推荐答案

下面我们只是采取相对布局之间的两个图像视图。第一帧（以上单元的拍摄图像的视图）是固定和按钮点击监听器，我们的框架一个简单的逻辑是在这里调整背后的第二个图像。没有太多的复杂。

Here just we take two image view between relative layout. First frame(above image-view in snap shoot) is fix and on button click-listener a second image which we adjust behind the frame a simple logic is here. Not much complicated.

但主要的事情是，我们希望框架的透明区域。这里框架并不像上面的截图，但不管，像脸部或手什么的，我predeclared所以裁剪（帧透明部分），并把它放在另一个图像。

But main things is that we want to transparent area of frame. Here frame is not as like above screenshot but whatever, like face or hands whatever, I predeclared so crop it(a frame transparent part )and put it in another image.
