Saya membuat aplikasi Android, dan perlu menghubungi daftar kontak ponsel. Saya perlu memanggil fungsi daftar kontak, memilih kontak, lalu kembali ke aplikasi saya dengan nama kontak. Berikut kode yang saya dapat di internet, tetapi tidak berhasil.

import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.Contacts.People;
import android.view.View;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;

public class Contacts extends ListActivity {

    private ListAdapter mAdapter;
    public TextView pbContact;
    public static String PBCONTACT;
    public static final int ACTIVITY_EDIT=1;
    private static final int ACTIVITY_CREATE=0;

    // Called when the activity is first created. 
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        Cursor C = getContentResolver().query(People.CONTENT_URI, null, null, null, null);
        startManagingCursor(C);

        String[] columns = new String[] {People.NAME};
        int[] names = new int[] {R.id.row_entry};

        mAdapter = new SimpleCursorAdapter(this, R.layout.mycontacts, C, columns, names);
        setListAdapter(mAdapter);
    } // end onCreate()
    // Called when contact is pressed
    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);

        Cursor C = (Cursor) mAdapter.getItem(position);
        PBCONTACT = C.getString(C.getColumnIndex(People.NAME));

        // RHS 05/06
        //pbContact = (TextView) findViewById(R.id.myContact);
        //pbContact.setText(new StringBuilder().append("b"));

        Intent i = new Intent(this, NoteEdit.class);
        startActivityForResult(i, ACTIVITY_CREATE);
    }
}

Saya tidak 100% yakin apa yang seharusnya dilakukan kode sampel Anda, tetapi cuplikan berikut akan membantu Anda 'memanggil fungsi daftar kontak, memilih kontak, lalu kembali ke aplikasi [Anda] dengan nama kontak'.

Ada tiga langkah untuk proses ini.

1. Izin

Tambahkan izin untuk membaca data kontak ke manifes aplikasi Anda.

<uses-permission android:name="android.permission.READ_CONTACTS"/>

2. Memanggil Pemilih Kontak

Di dalam Aktivitas Anda, buat Intent yang meminta sistem untuk menemukan Kegiatan yang dapat melakukan aksi PICK dari item di URI Kontak.

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

Panggil startActivityForResult, lewat Intent ini (dan integer kode permintaan, PICK_CONTACTdalam contoh ini). Hal ini akan menyebabkan Android untuk meluncurkan sebuah Kegiatan yang terdaftar untuk dukungan ACTION_PICKpada People.CONTENT_URI, kemudian kembali ke Kegiatan ini ketika pemilihan dibuat (atau dibatalkan).

startActivityForResult(intent, PICK_CONTACT);

3. Mendengarkan Hasilnya

Juga di Aktivitas Anda, ganti onActivityResultmetode untuk mendengarkan pengembalian dari Aktivitas 'pilih kontak' yang Anda luncurkan pada langkah 2. Anda harus memeriksa bahwa kode permintaan yang dikembalikan sesuai dengan nilai yang Anda harapkan, dan bahwa kode hasilnya RESULT_OK.

Anda bisa mendapatkan URI dari kontak yang dipilih dengan menelepon getData()pada data yang parameter Intent. Untuk mendapatkan nama kontak yang dipilih, Anda perlu menggunakan URI itu untuk membuat kueri baru dan mengekstrak nama dari kursor yang dikembalikan.

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
  super.onActivityResult(reqCode, resultCode, data);

  switch (reqCode) {
    case (PICK_CONTACT) :
      if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c =  getContentResolver().query(contactData, null, null, null, null);
        if (c.moveToFirst()) {
          String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
          // TODO Whatever you want to do with the selected contact name.
        }
      }
      break;
  }
}

Saya melakukannya dengan cara ini untuk rilis Android 2.2 Froyo: pada dasarnya gunakan gerhana untuk membuat kelas seperti: public class SomePickContactName memperluas Activity

lalu masukkan kode ini. Ingatlah untuk menambahkan variabel kelas privat dan CONSTANTS yang dirujuk dalam versi kode saya:

protected void onCreate(Bundle savedInstanceState) 
{
  super.onCreate(savedInstanceState);       
  Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
  startActivityForResult(intentContact, PICK_CONTACT);
}//onCreate

public void onActivityResult(int requestCode, int resultCode, Intent intent) 
{

  if (requestCode == PICK_CONTACT)
  {         
    getContactInfo(intent);         
    // Your class variables now have the data, so do something with it. 
  }
}//onActivityResult

protected void getContactInfo(Intent intent)
{

   Cursor cursor =  managedQuery(intent.getData(), null, null, null, null);      
   while (cursor.moveToNext()) 
   {           
       String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
       name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)); 

       String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

       if ( hasPhone.equalsIgnoreCase("1"))
           hasPhone = "true";
       else
           hasPhone = "false" ;

       if (Boolean.parseBoolean(hasPhone)) 
       {
        Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
        while (phones.moveToNext()) 
        {
          phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        }
        phones.close();
       }

       // Find Email Addresses
       Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);
       while (emails.moveToNext()) 
       {
        emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
       }
       emails.close();

    Cursor address = getContentResolver().query(
                ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,
                null,
                ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID + " = " + contactId,
                null, null);
    while (address.moveToNext()) 
    { 
      // These are all private class variables, don't forget to create them.
      poBox      = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX));
      street     = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
      city       = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));
      state      = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));
      postalCode = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
      country    = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY));
      type       = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.TYPE));
    }  //address.moveToNext()   
  }  //while (cursor.moveToNext())        
   cursor.close();
}//getContactInfo

Mencari-cari solusi API Level 5 menggunakan API ContactsContract Anda bisa sedikit memodifikasi kode di atas dengan yang berikut:

  Intent intent = new Intent(Intent.ACTION_PICK);
  intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
  startActivityForResult(intent, PICK_CONTACT);

Dan kemudian di onActivityResult gunakan nama kolom:

  ContactsContract.Contacts.DISPLAY_NAME

Berikut ini cuplikan kode untuk mendapatkan kontak:

        }

public void onActivityResult(int requestCode, int resultCode, Intent intent) 
{
  if (requestCode == PICK_CONTACT && intent != null) //here check whether intent is null R not
  {  
  }
}

karena tanpa memilih kontak apa pun itu akan memberikan pengecualian. jadi lebih baik untuk memeriksa kondisi ini.

Yang mengejutkan saya, Anda tidak memerlukan izin pengguna CONTACT_READ untuk membaca nama dan beberapa informasi dasar (Apakah kontak itu dibintangi, apa waktu panggilan terakhir). Namun Anda perlu izin untuk membaca detail kontak seperti nomor telepon.

Hati-hati saat bekerja dengan daftar kontak android.

Membaca daftar kontak dalam metode di atas berfungsi pada sebagian besar perangkat Android kecuali HTC One dan Sony Xperia. Membuang enam minggu saya untuk mencari tahu apa yang salah!

Sebagian besar tutorial yang tersedia secara online hampir mirip - pertama baca kontak "SEMUA", kemudian tunjukkan Listviewdengan ArrayAdapter. Ini bukan solusi yang efisien memori. Alih-alih mencari solusi di situs web lain terlebih dahulu, kunjungi developer.android.com. Jika solusi apa pun tidak tersedia di developer.android.com, Anda harus mencari di tempat lain.

Solusinya adalah menggunakan CursorAdapteralih-alih ArrayAdapteruntuk mengambil daftar kontak. Menggunakan ArrayAdapterakan berfungsi pada sebagian besar perangkat, tetapi itu tidak efisien. Hanya CursorAdaptermengambil sebagian dari daftar kontak pada saat run time ketika ListViewsedang digulir.

public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    ...
    // Gets the ListView from the View list of the parent activity
    mContactsList =
        (ListView) getActivity().findViewById(R.layout.contact_list_view);
    // Gets a CursorAdapter
    mCursorAdapter = new SimpleCursorAdapter(
            getActivity(),
            R.layout.contact_list_item,
            null,
            FROM_COLUMNS, TO_IDS,
            0);
    // Sets the adapter for the ListView
    mContactsList.setAdapter(mCursorAdapter);
}

Mengambil Daftar Kontak: Mengambil Daftar Kontak

Saya menggunakan metode ini untuk membaca Kontak

public static List<ContactItem> readPhoneContacts(Context context) {
        List<ContactItem> contactItems = new ArrayList<ContactItem>();
        try {
            Cursor cursor = context.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,
                    null, null, "upper("+ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + ") ASC");

            /*context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    null,
                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = ?",
                    new String[] { id },
                    ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");*/

            Integer contactsCount = cursor.getCount(); // get how many contacts you have in your contacts list
            if (contactsCount > 0) {
                while (cursor.moveToNext()) {

                    String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                    String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                        ContactItem contactItem = new ContactItem();
                        contactItem.setContactName(contactName);
                        //the below cursor will give you details for multiple contacts

            ex.printStackTrace();
        }


        return contactItems;
    }//loadContacts

hai saya punya kode untuk menyimpan kontak di database Anda dengan preferensi bersama di sini adalah kode saya

public class Main22Activity extends AppCompatActivity {
    EditText nameInput,phoneInput;
    TextView LargeText;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main22);
        nameInput = (EditText) findViewById(R.id.nameInput);
        phoneInput = (EditText) findViewById(R.id.phoneInput);

        LargeText = (TextView) findViewById(R.id.textView2);
    }

    public void saveInfo (View view){
        SharedPreferences sharedPref = getSharedPreferences("nameInfo" , Context.MODE_PRIVATE);
        SharedPreferences.Editor editor= sharedPref.edit();
        editor.putString("name", nameInput.getText().toString());
        editor.putString("phone", phoneInput.getText().toString());
        editor.apply();
        Toast.makeText(this, "Saved", Toast.LENGTH_LONG).show();
    }

    public void displayData(View view){
        SharedPreferences sharedPref = getSharedPreferences("nameInfo" , Context.MODE_PRIVATE);
        String name = sharedPref.getString("name", "");
        String ph = sharedPref.getString ("phone","");
        LargeText.setText(name + " " + ph);
    }
}

-> Add a permission to read contacts data to your application manifest.

<uses-permission android:name="android.permission.READ_CONTACTS"/>

-> Use Intent.Action_Pick in your Activity like below

Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
        startActivityForResult(contactPickerIntent, RESULT_PICK_CONTACT);

-> Then Override the onActivityResult()

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // check whether the result is ok
        if (resultCode == RESULT_OK) {
            // Check for the request code, we might be usign multiple startActivityForReslut
            switch (requestCode) {
            case RESULT_PICK_CONTACT:
               Cursor cursor = null;
        try {
            String phoneNo = null ;
            String name = null;           
            Uri uri = data.getData();            
            cursor = getContentResolver().query(uri, null, null, null, null);
            cursor.moveToFirst();           
            int  phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            phoneNo = cursor.getString(phoneIndex); 

            textView2.setText(phoneNo);
        } catch (Exception e) {
            e.printStackTrace();
        }
                break;
            }
        } else {
            Log.e("MainActivity", "Failed to pick contact");
        }
    }

This will work check it out

Saya menggunakan kode yang disediakan oleh @Colin MacKenzie - III. Terima kasih banyak!

Untuk seseorang yang mencari pengganti dariQuery yang 'usang' dikelola:

1st, dengan asumsi menggunakan lib dukungan v4:

import android.support.v4.app.LoaderManager;
import android.support.v4.content.CursorLoader;
import android.support.v4.content.Loader;

2:

your_(activity)_class implements LoaderManager.LoaderCallbacks<Cursor>

Ke-3,

// temporarily store the 'data.getData()' from onActivityResult
private Uri tmp_url;

4, timpa panggilan balik:

@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    // create the loader here!
    CursorLoader cursorLoader = new CursorLoader(this, tmp_url, null, null, null, null);
    return cursorLoader;
}

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
    getContactInfo(cursor); // here it is!
}

@Override
public void onLoaderReset(Loader<Cursor> loader) {
}

5:

public void initLoader(Uri data){
    // will be used in onCreateLoader callback
    this.tmp_url = data;
    // 'this' is an Activity instance, implementing those callbacks
    this.getSupportLoaderManager().initLoader(0, null, this);
}

6, kode di atas , kecuali bahwa saya mengubah param tanda tangan dari Intent ke Cursor:

protected void getContactInfo(Cursor cursor)
{

   // Cursor cursor =  managedQuery(intent.getData(), null, null, null, null);      
   while (cursor.moveToNext()) 
   {
        // same above ...
   } 

7, panggil initLoader:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (PICK_CONTACT == requestCode) {
        this.initLoader(data.getData(), this);
    }
}

8, jangan lupa bagian kode ini

    Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
    this.act.startActivityForResult(intentContact, PICK_CONTACT);
