About MarkView click

[Jerome-MJ]

关于markview的点击事件，我大概是通过以下方式来实现的，目前试验没问题还。
通过Chart的onTouch事件中判断此时的位置是否在markview中，如果是，则拦截事件消费，并调用performClick，达到点击效果，如果错误或者可以优化的麻烦告知我
About markview click event, I probably realized by the way, the test also no problem
Through the Chart onTouch event to determine whether the position in the markview, if it is, then intercept events consumption, and call the performClick, click to effect, if the error or optimization trouble tell me
