वास्तव में, आप Google द्वारा समर्थित लाइब्रेरी राउंडेड बायटैम्पडेबल फ़ायलेबल क्लास ( यहां और यहां ) के माध्यम से तृतीय पक्ष लाइब्रेरी का उपयोग करने के बजाय क्या उपयोग कर सकते हैं :
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
}
}
}

परिणाम:
और, मान लीजिए कि आप इसके ऊपर एक सीमा जोड़ना चाहते हैं, तो आप उदाहरण के लिए इसका उपयोग कर सकते हैं:
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>
और android:foreground="@drawable/stroke_drawable"लेआउट XML फ़ाइल में ImageView जोड़ें , और आपको यह मिलता है:
मुझे यकीन नहीं है कि छाया को कैसे जोड़ा जाए (जो पुराने एंड्रॉइड संस्करणों पर काम करेगा), हालांकि। फ़्लोटिंगएशनबटन ( "com.google.android.material: सामग्री" निर्भरता से ) का उपयोग करते हुए , मैं बिटमैप को FAB स्वयं भरने में विफल रहा। इसके बजाय इसका उपयोग करना और भी बेहतर हो सकता है अगर यह काम करे।
संपादित करें: यदि आप ऊँचाई की छाया जोड़ना चाहते हैं (एपीआई 21 से उपलब्ध), तो आपने जो लिखा है उसे थोड़ा बदल सकते हैं:
लेआउट XML फ़ाइल के अंदर:
<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)
}
}
कोड में:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
avatarImageView.outlineProvider = CircularShadowViewOutlineProvider()
