How to create a circular ImageView in Android?

How could I create a rounded ImageView in Android?

I have tried the following code, but it's not working fine.

Code:

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();
paint.setShader(shader);

Canvas c = new Canvas(circleBitmap);
c.drawCircle(bitmap.getWidth()/2, bitmap.getHeight()/2, bitmap.getWidth()/2, paint);

imageView.setImageBitmap(circleBitmap);

Image inside the circle:

How can I do this?

I too needed a rounded ImageView, I used the below code, you can modify it accordingly:

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class RoundedImageView extends ImageView {

	public RoundedImageView(Context context) {
		super(context);
	}

	public RoundedImageView(Context context, AttributeSet attrs) {
		super(context, attrs);
	}

	public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
	}

	@Override
	protected void onDraw(Canvas canvas) {

		Drawable drawable = getDrawable();

		if (drawable == null) {
			return;
		}

		if (getWidth() == 0 || getHeight() == 0) {
			return;
		}
		Bitmap b = ((BitmapDrawable) drawable).getBitmap();
		Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

		int w = getWidth();
		@SuppressWarnings("unused")
		int h = getHeight();

		Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
		canvas.drawBitmap(roundBitmap, 0, 0, null);

	}

	public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
		Bitmap sbmp;

		if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
			float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
			float factor = smallest / radius;
			sbmp = Bitmap.createScaledBitmap(bmp,
					(int) (bmp.getWidth() / factor),
					(int) (bmp.getHeight() / factor), false);
		} else {
			sbmp = bmp;
		}

		Bitmap output = Bitmap.createBitmap(radius, radius, Config.ARGB_8888);
		Canvas canvas = new Canvas(output);

		final String color = "#BAB399";
		final Paint paint = new Paint();
		final Rect rect = new Rect(0, 0, radius, radius);

		paint.setAntiAlias(true);
		paint.setFilterBitmap(true);
		paint.setDither(true);
		canvas.drawARGB(0, 0, 0, 0);
		paint.setColor(Color.parseColor(color));
		canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
				radius / 2 + 0.1f, paint);
		paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
		canvas.drawBitmap(sbmp, rect, rect, paint);

		return output;
	}
