推荐答案

这应该是你找什么： 该BackgroundBitmap指令将是你的此搜索和bitmapToDrawInTheCenter将是你的图像2。

This should be what you looking for: The backgroundBitmap would be your "image1" and the bitmapToDrawInTheCenter would be your "image2".

public void createImageInImageCenter(){
    Bitmap backgroundBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
    Bitmap bitmapToDrawInTheCenter = BitmapFactory.decodeResource(getResources(), R.drawable.ic_action_search);

    Bitmap resultBitmap = Bitmap.createBitmap(backgroundBitmap.getWidth(),backgroundBitmap.getHeight(), backgroundBitmap.getConfig());
    Canvas canvas = new Canvas(resultBitmap);
    canvas.drawBitmap(backgroundBitmap, new Matrix(), null);
    canvas.drawBitmap(bitmapToDrawInTheCenter, (backgroundBitmap.getWidth() - bitmapToDrawInTheCenter.getWidth()) / 2, (backgroundBitmap.getHeight() - bitmapToDrawInTheCenter.getHeight()) / 2, new Paint());

    ImageView image = (ImageView)findViewById(R.id.myImage);
    image.setImageBitmap(resultBitmap);
}
