How to make an image fit into a circular frame in android

Question

I have a ListView in which there is an ImageView, the image in the ImageView gets loaded dynamically after its fetched from the server

Answer 1

We can manage the height and width of an image from xml code and draw circle/oval from java code like

for oval view

ImageView img1 = (ImageView) findViewById(R.id.imageView1);
Bitmap bm = BitmapFactory.decodeResource(getResources(),
        R.drawable.user_image);
Bitmap conv_bm = getRoundedBitmap(bm);
img1.setImageBitmap(conv_bm);


public static Bitmap getRoundedBitmap(Bitmap bitmap)
{
    final Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
    final Canvas canvas = new Canvas(output);

    final int color = Color.RED;
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
    final RectF rectF = new RectF(rect);

    paint.setAntiAlias(true);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(color);
    canvas.drawOval(rectF, paint);
    paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);

    bitmap.recycle();

    return output;
  }

 }
