android-Custom Display Price Priceview

Reprint please indicate source: http://blog.csdn.net/goldenfish1919/article/details/44418883

Let's look at the effect we're going to make:

The price is divided into 3 parts, preceded by a ￥, an integral part of the middle, a fractional portion behind it, and a strikethrough in the middle.

Reference: http://blog.csdn.net/lmj623565791/article/details/44098729, we are actually more simple, customize a view, and then put three parts and delete lines are drawn separately.
