Sebenarnya, Anda dapat menggunakan apa yang disediakan Google melalui pustaka dukungan RoundedBitmapDrawableFactory (di sini dan di sini ), alih-alih menggunakan pustaka pihak ketiga:
Gradle:
implementation 'androidx.appcompat:appcompat:1.0.0-beta01'
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val originalDrawable = ContextCompat.getDrawable(this, R.drawable.avatar_1)!!
val bitmap = convertDrawableToBitmap(originalDrawable)
val drawable = RoundedBitmapDrawableFactory.create(resources, bitmap)
drawable.setAntiAlias(true)
drawable.cornerRadius = Math.max(bitmap.width, bitmap.height) / 2.0f
avatarImageView.setImageDrawable(drawable)
}
companion object {
@JvmStatic
fun convertDrawableToBitmap(drawable: Drawable): Bitmap {
if (drawable is BitmapDrawable)
return drawable.bitmap
// We ask for the bounds if they have been set as they would be most
// correct, then we check we are > 0
val bounds = drawable.bounds
val width = if (!bounds.isEmpty) bounds.width() else drawable.intrinsicWidth
val height = if (!bounds.isEmpty) bounds.height() else drawable.intrinsicHeight
// Now we check we are > 0
val bitmap = Bitmap.createBitmap(if (width <= 0) 1 else width, if (height <= 0) 1 else height,
Bitmap.Config.ARGB_8888)
val canvas = Canvas(bitmap)
drawable.setBounds(0, 0, canvas.width, canvas.height)
drawable.draw(canvas)
return bitmap
}
}
}

Hasil:
Dan, misalkan Anda ingin menambahkan perbatasan di atasnya, Anda dapat menggunakan ini misalnya:
stroke_drawable.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<stroke
android:width="4dp" android:color="@android:color/black"/>
</shape>
Dan tambahkan android:foreground="@drawable/stroke_drawable"
ke ImageView dalam file XML layout, dan Anda mendapatkan ini:
Saya tidak yakin bagaimana cara menambahkan shadow (yang akan bekerja pada versi Android yang lebih lama). Menggunakan FloatingActionButton (dari dependensi "com.google.android.material: material" ), saya gagal membuat bitmap mengisi FAB itu sendiri. Sebaliknya, menggunakannya bisa lebih baik jika berhasil.
EDIT: jika Anda ingin menambahkan bayangan elevasi (tersedia dari API 21), Anda dapat mengubah sedikit apa yang saya tulis:
Di dalam file XML layout:
<androidx.appcompat.widget.AppCompatImageView android:padding="4dp"
android:id="@+id/avatarImageView" android:layout_width="100dp" android:layout_height="100dp" android:elevation="8dp"
android:layout_gravity="center" android:background="@drawable/stroke_drawable" tools:srcCompat="@drawable/avatar_1"/>
CircularShadowViewOutlineProvider.kt
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
class CircularShadowViewOutlineProvider : ViewOutlineProvider() {
override fun getOutline(view: View, outline: Outline) {
val size = Math.max(view.width, view.height)
outline.setRoundRect(0, 0, size, size, size / 2f)
}
}
Dalam kode:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
avatarImageView.outlineProvider = CircularShadowViewOutlineProvider()
