我目前使用 ViewFlipper 我有两个不同的布局主要活动。我想用三分之一的布局，但我只能找到 showNext（）和显示previous（）命令。有人能告诉我如何使用，以实现第三布局 ViewFlipper ？

I am currently using ViewFlipper for my main activity with two different layouts. I want to use a third layout, but I can only find the showNext() and showPrevious() commands. Can someone show me how to implement a third layout using ViewFlipper?

推荐答案

做出了表率为您展示一个ViewFlipper HOWTO显示不同的看法。

Made an example for you that shows howto display different views in a ViewFlipper.

的实施例的布局是由以下几部分组成。有三个单选按钮。一个ViewFlipper放在下面的单选按钮。该鳍状肢保存与不同的文本三种不同的简单看法。

The layout of the example is made up of the following parts. There are three radio buttons. A ViewFlipper is placed below the radio buttons. This flipper holds three different simple views with different texts.

单选按钮，然后连接到Java code进行监听，这将改变，这取决于单选按钮当前选择，到ViewFlipper显示的视图。

The radio buttons are then hooked up to a listener in the java code that will change the view displayed by the ViewFlipper depending on which radio button that currently is chosen.
