但是这个方法设置的item的Layout必须是带有onMeasure()方法的控件，否则在计算的时候会报错，建议使用LinearLayout。

再一个思路相同，但是，不是额外做方法来实现onMeasure()方法的计算LIstView的大小，而是自己继承ListView，重写ListView的onMeasure()方法，来自己计算ListView的高度，然后再xml中直接使用这个自定义的ListView就可以了。

这是解决让作为Item的ListView显示全部内容的方案，但是有些时候我们是想让作为Item的ListView不用全部显示，而是可以进行滑动，要解决这个问题就需要了解一下Android对事件的分发机制了

我的解决方案是集成ListView，重写interceptTouchEvent使其返回false来取消父ListView对触摸事件的拦截，将触摸事件分发到子View来处理。然后在使用的时候，将其作为父ListView使用，就可以使子ListView可以滑动了。思想来源于下面链接的6楼
