Andorid Clip implements a custom progress bar effect instance

The Android system provides a horizontal progress bar for us to show progress, and the horizontal progress bar is used to display the progress of the clip drawable technology
Here's a concrete example to illustrate the use of clip drawable.

There is a knowledge to note:

Clip type of picture default clipping level is 0, at this time is all cropping, the picture is not visible;
When the level is 10000, the picture is not cropped and the picture is all visible

The results of the program run: The first is the initial interface, the second is a click of 5 times the interface, the third one for the click 10 interface

Create a new Android project called Clip drawable.
