    Bitmap bitmap1 = null; // define it
    Bitmap bitmap2 = null; // define it

    Bitmap resultBitmap = Bitmap.createBitmap(bitmap1.getWidth(), bitmap1.getHeight(), Bitmap.Config.ARGB_8888);

    Canvas c = new Canvas(resultBitmap);

    c.drawBitmap(bitmap1, 0, 0, null);

    Paint p = new Paint();
    p.setAlpha(127);

    c.drawBitmap(bitmap2, 0, 0, p);

    // Your final bitmap is resultBitmap
