Question

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

    final int color = 0xff424242;
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
    final RectF rectF = new RectF(rect);
    final float roundPx = 12;

    paint.setAntiAlias(true);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(color);
    canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

    paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);

    return output;
}

I am trying use this code for rounding bitmap, but I don’t what is Mode.SRC_in and Config.ARGB_8888. I have error with them. What should I do here?

For PorterDuffXfermode, you have to write import android.graphics.PorterDuffXfermode;

For Config.ARGB_8888, you have to write import android.graphics.Bitmap.Config;

Otherwise Direct press CTRL + SHIFT + O to organize imports.
