Android : How to Draw multiple images inside the same imageview but shifted in the y coordinate?

问题

In my android application I have a horizontal list view and a vertical one. The vertical view contains images. When any of the images is touched, it must go to the horizontal view, but every 3 of them must be drawn over each other in the same image view and shifted upwards so that all the images will appear.

Thanks

use this code for show 2 image in one image:

    ImageView myImageView = (ImageView) findViewById(R.id.img1);
    Bitmap bitmap1 = BitmapFactory.decodeResource(getResources(), R.drawable.call);
    Bitmap bitmap2 = BitmapFactory.decodeResource(getResources(), R.drawable.available);
    Bitmap combinedBitmap = getCombinedBitmap(pic2, pic1);

    myImageView.setImageBitmap(b);

and this is the getCombinedBitmap() method :

public Bitmap getCombinedBitmap(Bitmap b, Bitmap b2) {
    Bitmap drawnBitmap = null;

    try {
        drawnBitmap = Bitmap.createBitmap(200, 200, Config.ARGB_8888);

        Canvas canvas = new Canvas(drawnBitmap);
        // JUST CHANGE TO DIFFERENT Bitmaps and coordinates .
        canvas.drawBitmap(b, 0, 0, null);
        canvas.drawBitmap(b2, 0, 0, null);
        //for more images :
        // canvas.drawBitmap(b3, 0, 0, null);
        // canvas.drawBitmap(b4, 0, 0, null);

    }
    catch (Exception e) {
        e.printStackTrace();
    }
    return drawnBitmap;
}

enjoy :)
