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);
}
