在Android中以编程方式创建位图动画的最佳方法

Question

I have a board game app that creates a lot (hundreds) of bitmaps, and constantly changes them as the game progresses. These bitmaps are created, not loaded from a resource... so they have no R.id to refer to.

I would like to animate some of them, eg a bitmap moving from one loction to another when a player taps to move it. What is the best way to do this?

Note, this is 2.1 and the bitmaps are drawn on a canvas via a matrix translate.

Answer 1

Make this function to get image from drawable folder

  private Bitmap getImageBitmap(){
  int resID = getResources().getIdentifier(uri, "drawable",
            "a.b.c");
    Bitmap mBitmap = BitmapFactory.decodeResource(getResources(), resID);
    return mBitmap;
   }

For set the image , where do you you want>

 ImageView imageview01.setImageBitmap(getImageBitmap("name of bitmap");

if you want more about bitmap. then you may try this links.
