您可以使用createBitmap（）来提取当前位图的子集。

Answer 3

take a look at the following link. Should provide a good stepping stone to step up a ui with pinch to zoom and scroll and finally once you have what you want you can use a second view as your crop region. depends on what your looking for otherwise createBitmap option also works. http://blog.sephiroth.it/2011/04/04/imageview-zoom-and-scroll/

 View view = findViewById(R.id.crop_region);
 view.setDrawingCacheEnabled(true);
 view.buildDrawingCache();
 Bitmap cropBitmap = view.getDrawingCache();
