Android禁止ViewPager的左右滑动

有时候在开发中会遇到一些“诡异”的要求，比如在ViewPager中嵌入ListView，或者再嵌入一个ViewPager，那么在滑动的时候就会造成被嵌入的XXView不能滑动了，那么现在就把最外层的ViewPager禁止滑动吧，让被嵌入的XXView获得滑动事件好了。关于解决方法，网上也有很多说法，基本上是一致的，但是需要理解这个Android下的事件分发机制才行，不明白事件分发机制的，上网查些资料看看，然后我这里也有简单的介绍，请参看博客Android自定义控件——侧滑菜单的下方。

怎样禁止ViewPager左右滑动呢？大致就是重写ViewPager，覆盖ViewPager的onInterceptTouchEvent(MotionEvent arg0)方法和onTouchEvent(MotionEvent arg0)方法，这两个方法的返回值都是boolean类型的，只需要将返回值改为false，那么ViewPager就不会消耗掉手指滑动的事件了，转而传递给上层View去处理或者该事件就直接终止了。下面是我的自定义ViewPager。

以上代码特别简单，大家可以直接拷贝使用，无需做任何修改。为了操作方便，我在这个自定义的ViewPager里设置了一个boolean类型的控制变量，并且向外提供了控制ViewPager是否禁止滑动的方法，这样就显得灵活一点了。以下是自定义ViewPager在布局文件中的定义。
