Izinkan pengguna memilih kamera atau galeri untuk gambar

Apa yang saya coba lakukan tampaknya sangat sederhana, tetapi setelah beberapa hari mencari saya tidak bisa mengetahuinya.

Saya memiliki aplikasi yang memungkinkan pengguna untuk memilih beberapa (hingga 5) gambar. Saya menggunakan ImageView. Ketika pengguna mengklik pada ImageView, saya ingin mengizinkan mereka opsi untuk

1. Pilih gambar dari galeri, atau
2. Gunakan kamera untuk mengambil gambar.

Saya mulai dengan menggunakan ACTION_GET_CONTENTniat, dan itu berhasil dengan baik untuk sampai ke galeri. Jadi saya mencoba menggunakan ACTION_PICK_ACTIVITYmaksud untuk memungkinkan pengguna memilih kamera atau galeri:

Intent pickIntent = new Intent(Intent.ACTION_PICK_ACTIVITY);
Intent gallIntent=new Intent(Intent.ACTION_GET_CONTENT);
gallIntent.setType("image/*"); 
Intent camIntent = new Intent("android.media.action.IMAGE_CAPTURE");
pickIntent.putExtra(Intent.EXTRA_INTENT, camIntent);
pickIntent.putExtra(Intent.EXTRA_INTENT, gallIntent)
pickIntent.putExtra(Intent.EXTRA_TITLE, "Select Source");
startActivityForResult(pickIntent, IMAGE_SELECTOR);

Tapi sepertinya saya hanya bisa menambahkan satu EXTRA_INTENT. Menu muncul seperti yang diharapkan, tetapi satu-satunya pilihan adalah Galeri dan File .... no Camera).

Apakah ada cara yang lebih baik / lebih mudah untuk melakukan ini yang saya lewatkan? Terima kasih atas bantuannya.

Anda harus membuat dialog pemilih Anda sendiri menggabungkan kedua hasil resolusi maksud.

Untuk melakukan ini, Anda perlu meminta PackageManager dengan PackageManager.queryIntentActivities () untuk kedua maksud asli dan membuat daftar akhir dari Maksud yang mungkin dengan satu Maksud baru untuk setiap kegiatan yang diambil seperti ini:

List<Intent> yourIntentsList = new ArrayList<Intent>();

List<ResolveInfo> listCam = packageManager.queryIntentActivities(camIntent, 0);
for (ResolveInfo res : listCam) {
    final Intent finalIntent = new Intent(camIntent);
    finalIntent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
    yourIntentsList.add(finalIntent);
}

List<ResolveInfo> listGall = packageManager.queryIntentActivities(gallIntent, 0);
for (ResolveInfo res : listGall) {
    final Intent finalIntent = new Intent(gallIntent);
    finalIntent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
    yourIntentsList.add(finalIntent);
}

(Saya menulis ini langsung di sini jadi ini mungkin tidak dapat dikompilasi)

Kemudian, untuk info lebih lanjut tentang membuat dialog khusus dari daftar, lihat https://developer.android.com/guide/topics/ui/dialogs.html#AlertDialog

Cara meluncurkan Intent tunggal untuk memilih gambar dari Galeri atau Kamera, atau aplikasi apa pun yang terdaftar untuk menelusuri sistem file.

Daripada membuat Dialog dengan daftar opsi Intent, lebih baik menggunakan Intent.createChooser untuk mendapatkan akses ke ikon grafis dan nama pendek dari berbagai 'Kamera', 'Galeri' dan bahkan aplikasi browser filesystem Pihak Ketiga. seperti 'Astro', dll.

Ini menjelaskan cara menggunakan niat pemilih standar dan menambahkan maksud tambahan untuk itu.

private Uri outputFileUri;

private void openImageIntent() {

    // Determine Uri of camera image to save.
    final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "MyDir" + File.separator);
    root.mkdirs();
    final String fname = Utils.getUniqueImageFilename();
    final File sdImageMainDirectory = new File(root, fname);
    outputFileUri = Uri.fromFile(sdImageMainDirectory);

    // Camera.
    final List<Intent> cameraIntents = new ArrayList<Intent>();
    final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    final PackageManager packageManager = getPackageManager();
    final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
    for(ResolveInfo res : listCam) {
        final String packageName = res.activityInfo.packageName;
        final Intent intent = new Intent(captureIntent);
        intent.setComponent(new ComponentName(packageName, res.activityInfo.name));
        intent.setPackage(packageName);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        cameraIntents.add(intent);
    }

    // Filesystem.
    final Intent galleryIntent = new Intent();
    galleryIntent.setType("image/*");
    galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

    // Chooser of filesystem options.
    final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");

    // Add the camera options.
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));

    startActivityForResult(chooserIntent, YOUR_SELECT_PICTURE_REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == YOUR_SELECT_PICTURE_REQUEST_CODE) {
            final boolean isCamera;
            if (data == null) {
                isCamera = true;
            } else {
                final String action = data.getAction();
                if (action == null) {
                    isCamera = false;
                } else {
                    isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                }
            }

            Uri selectedImageUri;
            if (isCamera) {
                selectedImageUri = outputFileUri;
            } else {
                selectedImageUri = data == null ? null : data.getData();
            }
        }
    }
}

Saya menemukan ini . Menggunakan:

galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

untuk salah satu maksud menunjukkan kepada pengguna pilihan untuk memilih 'dokumen' di Android 4, yang menurut saya sangat membingungkan. Menggunakan ini sebagai gantinya menunjukkan opsi 'galeri':

Intent pickIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

Saya juga memiliki masalah ini dan apa yang saya lakukan adalah membuat AlertDialog dan menggunakan metode setItems () bersama dengan pendengar DialogInterface:

AlertDialog.Builder getImageFrom = new AlertDialog.Builder(Fotos.this);
getImageFrom.setTitle("Select:");
final CharSequence[] opsChars = {getResources().getString(R.string.takepic), getResources().getString(R.string.opengallery)};
getImageFrom.setItems(opsChars, new android.content.DialogInterface.OnClickListener(){

    @Override
    public void onClick(DialogInterface dialog, int which) {
        if(which == 0){
            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
        }else
            if(which == 1){
                Intent intent = new Intent();
                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(Intent.createChooser(intent,
                    getResources().getString(R.string.pickgallery)), SELECT_PICTURE);
            }
        dialog.dismiss();
    }
});

Saya telah menggabungkan beberapa solusi untuk membuat util lengkap untuk memilih gambar dari Galeri atau Kamera. Ini adalah fitur util ImagePicker (juga dalam lib Github ):

• Intensi yang digabungkan untuk Galeri dan permintaan kamera.
• Ubah ukuran gambar besar yang dipilih (mis .: 2500 x 1600)
• Putar gambar jika perlu

Tangkapan layar:

Sunting : Berikut adalah fragmen kode untuk mendapatkan Intent gabungan untuk Galeri dan aplikasi Kamera bersama. Anda dapat melihat kode lengkap di ImagePicker util (juga di lib Github ):

public static Intent getPickImageIntent(Context context) {
    Intent chooserIntent = null;

    List<Intent> intentList = new ArrayList<>();

    Intent pickIntent = new Intent(Intent.ACTION_PICK,
            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    takePhotoIntent.putExtra("return-data", true);
    takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(context)));
    intentList = addIntentsToList(context, intentList, pickIntent);
    intentList = addIntentsToList(context, intentList, takePhotoIntent);

    if (intentList.size() > 0) {
        chooserIntent = Intent.createChooser(intentList.remove(intentList.size() - 1),
                context.getString(R.string.pick_image_intent_text));
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentList.toArray(new Parcelable[]{}));
    }

    return chooserIntent;
}

private static List<Intent> addIntentsToList(Context context, List<Intent> list, Intent intent) {
    List<ResolveInfo> resInfo = context.getPackageManager().queryIntentActivities(intent, 0);
    for (ResolveInfo resolveInfo : resInfo) {
        String packageName = resolveInfo.activityInfo.packageName;
        Intent targetedIntent = new Intent(intent);
        targetedIntent.setPackage(packageName);
        list.add(targetedIntent);
    }
    return list;
}

kode ini akan membantu Anda, karena ada dua tombol satu untuk Kamera dan satu lagi untuk Galeri, dan Gambar akan ditampilkan di ImageView

https://github.com/siddhpuraamitr/Choose-Image-From-Gallery-Or-Camera

Bagi mereka yang mendapatkan kesalahan pada 4.4 ke atas saat mencoba menggunakan pemilihan Gambar dapat menggunakan kode di bawah ini.

Daripada membuat Dialog dengan daftar opsi Intent, lebih baik menggunakan Intent.createChooser untuk mendapatkan akses ke ikon grafis dan nama pendek dari berbagai 'Kamera', 'Galeri' dan bahkan aplikasi browser filesystem Pihak Ketiga. seperti 'Astro', dll.

            if (data == null) {
                isCamera = true;
            } else {
                final String action = data.getAction();
                if (action == null) {

                final Bitmap bitmap = BitmapFactory.decodeFile(selectedImageUri.getPath(), options);
                preview.setImageBitmap(bitmap);

                "Sorry! Failed to capture image", Toast.LENGTH_SHORT)
                .show();
    }
}

Ini harus menangani masalah null outputFileUri Tina:

private static final String STORED_INSTANCE_KEY_FILE_URI = "output_file_uri";

@Override
public void onSaveInstanceState( Bundle outState ) {
    super.onSaveInstanceState( outState );

    if ( outputFileUri != null ) {
        outState.putString( STORED_INSTANCE_KEY_FILE_URI, outputFileUri.toString() );
    }
}

@Override
public void onViewStateRestored( Bundle savedInstanceState ) {
    super.onViewStateRestored( savedInstanceState );

    if ( savedInstanceState != null ) {
      final String outputFileUriStr = savedInstanceState.getString( STORED_INSTANCE_KEY_FILE_URI );
      if ( outputFileUriStr != null && !outputFileUriStr.isEmpty() ) {
          outputFileUri = Uri.parse( outputFileUriStr );
      }
    }
}

Catatan: Saya menggunakan kode ini di dalam android.support.v4.app.Fragment metode yang diganti dapat berubah tergantung pada versi Fragmen / Aktivitas yang Anda gunakan.

Anda dapat membuat dialog opsi

Buka kamera:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                        cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                                MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
                        if (cameraIntent.resolveActivity(getActivity().getPackageManager()) != null) {
                            startActivityForResult(cameraIntent, CAMERA_IMAGE);
                        }

Galeri Terbuka:

if (Build.VERSION.SDK_INT <= 19) {
            Intent i = new Intent();
            i.setType("image/*");
            i.setAction(Intent.ACTION_GET_CONTENT);
            i.addCategory(Intent.CATEGORY_OPENABLE);
            startActivityForResult(i, GALLARY_IMAGE);
        } else if (Build.VERSION.SDK_INT > 19) {
            Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(intent, GALLARY_IMAGE);
        }

Untuk mendapatkan hasil seleksi

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == Activity.RESULT_OK) {
            if (requestCode == GALLARY_IMAGE) {
                Uri selectedImageUri = data.getData();
                String selectedImagePath = getRealPathFromURI(selectedImageUri);
            } else if (requestCode == CAMERA_IMAGE) {
                Bundle extras = data.getExtras();
                Bitmap bmp = (Bitmap) extras.get("data");
                SaveImage(bmp);
            }
        }
    }

 public String getRealPathFromURI(Uri uri) {
        if (uri == null) {
            return null;
        }
        String[] projection = {MediaStore.Images.Media.DATA};
        Cursor cursor = getActivity().getContentResolver().query(uri, projection, null, null, null);
        if (cursor != null) {
            int column_index = cursor
                    .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
            cursor.moveToFirst();
            return cursor.getString(column_index);
        }
        return uri.getPath();
    }

Metode untuk menyimpan gambar yang diambil

 private void SaveImage(final Bitmap finalBitmap) {
        Thread t = new Thread(new Runnable() {
            @Override
            public void run() {
                String root = Environment.getExternalStorageDirectory().toString();

                File myDir = new File(root + "/Captured Images/");
                if (!myDir.exists())
                    myDir.mkdirs();

                String fname = "/image-" + System.currentTimeMillis() + ".jpg";
                File file = new File(myDir, fname);
                try {
                    FileOutputStream out = new FileOutputStream(file);
                    finalBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
                    out.flush();
                    out.close();
                    localImagePath = myDir + fname;
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }


        });
        t.start();

    }

Anda dapat mencoba ini:

Untuk membuka Galeri:

private void browseImage() {

        try {
  Intent galleryIntent = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
  startActivityForResult(galleryIntent, GALLERY_IMAGE_PICK); //GALLERY_IMAGE_PICK it is a string
  } catch (Exception e) {}
     }

Untuk membuka Kamera:

 private void captureImage() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);

    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);

    // start the image capture Intent

    startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);

}

Ini sederhana dengan menggunakan AlertDialog dan Intent.ACTION_PICK

    //camOption is a string array contains two items (Camera, Gallery)
    AlertDialog.Builder builder = new AlertDialog.Builder(CarPhotos.this);
    builder.setTitle(R.string.selectSource)
    .setItems(R.array.imgOption, new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which)

     {

        if (which==0) {
        Intent intent = new Intent(this, CameraActivity.class);
        startActivityForResult(intent, REQ_CAMERA_IMAGE);               }

        if (which==1) {
        Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(i, RESULT_LOAD_IMAGE);
            }

     }
            });
             builder.create();
             builder.show();

Membangun atas jawaban David, dua penny saya pada onActivityResult()bagian. Ini menangani perubahan yang diperkenalkan pada 5.1.1 dan mendeteksi apakah pengguna telah memilih satu atau beberapa gambar dari perpustakaan.

private enum Outcome {
    camera, singleLibrary, multipleLibrary, unknown
}

/**
 * Returns a List<Uri> containing the image uri(s) chosen by the user
 *
 * @param data      The data intent coming from the onActivityResult()
 * @param cameraUri The uri that had been passed to the intent when the chooser was invoked.
 * @return A List<Uri>, never null.
 */
public List<Uri> getPicturesUriFromIntent(Intent data, Uri cameraUri) {

    Outcome outcome = Outcome.unknown;

    if (data == null || (data.getData() == null && data.getClipData() == null)) {
        outcome = Outcome.camera;
    } else if (data.getData() != null && data.getClipData() == null) {
        outcome = Outcome.singleLibrary;
    } else if (data.getData() == null) {
        outcome = Outcome.multipleLibrary;
    } else {
        final String action = data.getAction();
        if (action != null && action.equals(MediaStore.ACTION_IMAGE_CAPTURE)) {
            outcome = Outcome.camera;
        }
    }

    // list the uri(s) we got back
    List<Uri> uris = new ArrayList<>();
    switch (outcome) {
        case camera:
            uris.add(cameraUri);
            break;

        case singleLibrary:
            uris.add(data.getData());
            break;

        case multipleLibrary:
            final ClipData clipData = data.getClipData();
            for (int i = 0; i < clipData.getItemCount(); i++) {
                ClipData.Item item = clipData.getItemAt(i);
                uris.add(item.getUri());
            }
            break;
    }

    return uris;
}

Coba dengan cara ini

final CharSequence[] items = { "Take Photo", "Choose from Library",
            "Cancel" };

    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    builder.setTitle("Add Photo!");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int item) {
            if (items[item].equals("Take Photo")) {
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                File f = new File(android.os.Environment
                        .getExternalStorageDirectory(), "temp.jpg");
                intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
                startActivityForResult(intent, REQUEST_CAMERA);
            } else if (items[item].equals("Choose from Library")) {
                Intent intent = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                intent.setType("image/*");
                startActivityForResult(
                        Intent.createChooser(intent, "Select File"),
                        SELECT_FILE);
            } else if (items[item].equals("Cancel")) {
                dialog.dismiss();
            }
        }
    });
    builder.show();

Kemudian buat metode hasil aktivitas dan lakukan sesuatu seperti ini

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if (requestCode == REQUEST_CAMERA) {
            File f = new File(Environment.getExternalStorageDirectory()
                    .toString());
            for (File temp : f.listFiles()) {
                if (temp.getName().equals("temp.jpg")) {
                    f = temp;
                    break;
                }
            }
            try {
                Bitmap bm;
                BitmapFactory.Options btmapOptions = new BitmapFactory.Options();

                bm = BitmapFactory.decodeFile(f.getAbsolutePath(),
                        btmapOptions);

                // bm = Bitmap.createScaledBitmap(bm, 70, 70, true);
                ivImage.setImageBitmap(bm);

                String path = android.os.Environment
                        .getExternalStorageDirectory()
                        + File.separator
                        + "Phoenix" + File.separator + "default";
                f.delete();
                OutputStream fOut = null;
                File file = new File(path, String.valueOf(System
                        .currentTimeMillis()) + ".jpg");
                try {
                    fOut = new FileOutputStream(file);
                    bm.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
                    fOut.flush();
                    fOut.close();
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        } else if (requestCode == SELECT_FILE) {
            Uri selectedImageUri = data.getData();

            String tempPath = getPath(selectedImageUri, MainActivity.this);
            Bitmap bm;
            BitmapFactory.Options btmapOptions = new BitmapFactory.Options();
            bm = BitmapFactory.decodeFile(tempPath, btmapOptions);
            ivImage.setImageBitmap(bm);
        }
    }
}

Memilih kamera atau galeri untuk gambar di Android

Saya telah bekerja keras pada Pemilihan Gambar Kamera atau galeri , dan membuat beberapa kelas util untuk pekerjaan ini. Dengan penggunaan kelas ini, 'Memilih kamera gambar atau galeri terlalu mudah' , hanya butuh 5-10 permen untuk pengembangan Anda.

Langkah-1: Tambahkan kelas-kelas ini dalam kode Anda.

ImagePickerUtils: - http://www.codesend.com/view/f8f7c637716bf1c693d1490635ed49b3/

BitmapUtils: - http://www.codesend.com/view/81c1c2a3f39f1f7e627f01f67be282cf/

ConvertUriToFilePath: - http://www.codesend.com/view/f4668a29860235dd1b66eb419c5a58b5/

MediaUtils: - https://codeshare.io/5vKEMl

Kita perlu Menambahkan Izin ini dalam bentuk manifest:

  <uses-permission android:name="android.permission.CAMERA" />
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
  <uses-feature android:name="android.hardware.camera" />
  <uses-feature android:name="android.hardware.camera.autofocus" />

Fungsi kelas ini (checkAndRequestPermissions) otomatis memeriksa izin di Android-Marshmallow dan Android - Nougat.

Langkah 2. Memanggil kelas kamera untuk meluncurkan maksud kamera:

 //Create a global veriable .  
     private Uri mCameraUri;
     private static final int CAMERA_REQUEST_CODE = 100;

// Call this function when you wants to select or capture an Image.
       mCameraUri = ImagePickerUtils.createTakePictureIntent(this, CAMERA_REQUEST_CODE);

Langkah-3: Tambahkan onActivityResult di Aktivitas Anda untuk menerima data dari Intent

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == Activity.RESULT_OK) {
            Uri fileUri = ImagePickerUtils.getFileUriOfImage(this, data, mCameraUri);
            try {
                Bitmap bitmap = null;
                if (CAMERA_REQUEST_CODE == requestCode) {
                    bitmap = new BitmapUtils().getDownsampledBitmap(this, fileUri, imageView.getWidth(), imageView.getHeight());
                }
                if (bitmap != null)
                imageView.setImageBitmap(bitmap);

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

Saya harap ini membantu Anda, Jika ada yang punya saran untuk meningkatkan kelas ini, silakan tambahkan ulasan Anda di komentar.

Per David Manpearl jawab
https://stackoverflow.com/a/12347567/7226732

kita hanya perlu memodifikasi onActivityResult () seperti

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == YOUR_SELECT_PICTURE_REQUEST_CODE) {
            final boolean isCamera;
            if (data.getExtras() == null) {
                isCamera = true;
            } else {
                final String action = data.getAction();
                if (action == null) {
                    isCamera = false;
                } else {
                    isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                }
            }
            Uri selectedImageUri;
            if (isCamera) {
                selectedImageUri = fileUri;
                try {
                    Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImageUri);
                    Toast.makeText(CreateWaterType.this, "Image Saved!", Toast.LENGTH_SHORT).show();
                    image_view.setImageBitmap(bitmap);

                } catch (IOException e) {
                    e.printStackTrace();
                    Toast.makeText(CreateWaterType.this, "Failed!", Toast.LENGTH_SHORT).show();
                }

            } else {
                selectedImageUri = data == null ? null : data.getData();
                try {
                    Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImageUri);

                    Toast.makeText(CreateWaterType.this, "Image Saved!", Toast.LENGTH_SHORT).show();
                    image_view.setImageBitmap(bitmap);

                } catch (IOException e) {
                    e.printStackTrace();
                    Toast.makeText(CreateWaterType.this, "Failed!", Toast.LENGTH_SHORT).show();
                }
            }
        }
    }
}

dan atur pengambilan atau pengambilan gambar dalam tampilan gambar.
