Please help me to set bitmap in circular imageview.


How to&Answers:

I am curious about how you created a circular ImageView. Can you share that secret ??
As far as creating a circular Bitmap is concerned, create a BitmapShader from the bitmap you want to show. Then create a ShapeDrawable (Oval) and assign the bitmap shader to it. Draw the drawable. Bam! circular image!

Bitmap bitmap = getthebitmapyouwanttoshowinacirclefromsomewhere;
Bitmap circleBitmap = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);

BitmapShader shader = new BitmapShader (bitmap,  TileMode.CLAMP, TileMode.CLAMP);
Paint paint = new Paint();
Canvas c = new Canvas(circleBitmap);
c.drawCircle(bitmap.getWidth()/2, bitmap.getHeight()/2, bitmap.getWidth()/2, paint);
