Android Camera custom zoom anywhere on the camera view

Question

有没有一种方法，我可以通过触摸手势在相机预览上选择聚焦区域并放大到该特定区域？

Answer 1

The short answer is: yes, you can.

If your camera supports video resolution higher than the preview area, zoom in can show more details. Often, it's not the case, and zoomed in picture will not look good.
