本文介绍了TabHost与多个ViewFlippers - GestureListener的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个TabHost有两个ViewFlippers，每个ViewFlipper里面有三个列表视图。我想离开＆LT; - >右键手势侦听ViewFlipper三个列表视图之间滑动。向上/向下运动的列表视图似乎工作，但我似乎无法得到ViewFlipper工作。

解决方案
不要使用ViewFlipper，使用的。这是一个相对较晚除了为正是这种图形用户界面的创建的SDK。
I have a TabHost that has two ViewFlippers, and inside each ViewFlipper are three ListViews. I would like to have left<->right gesture listener for the ViewFlipper to slide between the three ListViews. The Up/Down motion for the ListViews seems to work, but I cannot seem to get the ViewFlipper to work.

解决方案
Don't use a ViewFlipper, use a ViewPager. It's a relatively late addition to the SDK that was created for exactly this sort of GUI.
