Crop square image to circle – Programmatically

by

Once the bitmap is retrieved RoundedBitmapDrawableFactory can be used to generate a RoundedBitmapDrawable from the v4 Support Library. That Drawable can then be applied to an ImageView or directly drawn to a Canvas.

// Create the RoundedBitmapDrawable.
RoundedBitmapDrawable roundDrawable = RoundedBitmapDrawableFactory.create(getResources(), bitmap);
roundDrawable.setCircular(true);

// Apply it to an ImageView.
ImageView imageView = (ImageView)findViewById(R.id.imageView);
imageView.setImageDrawable(roundDrawable);

// Alternatively, draw it to an canvas (e.g. in onDraw where a Canvas is available).
// setBounds since there's no View handling size and positioning.
roundDrawable.setBounds(left, top, right, bottom);
roundDrawable.draw(canvas);
