Android 手势监听和图片放大缩小功能实例

本源代码演示Android TabHost组件嵌套的用法示例，屏幕上部和底部均出现TAb，下部的TAB是在上部指定TAB激活时才显示，实现了双层嵌套的TAB视图效果。本例子继承了TabActivity，注意：在设置双层嵌套时，要注意其TAB的顺序，若错乱可能会导致嵌套失败。 　　对于TabHost、布局文件中必须包含TabHost、TabWidget 、FrameLayout ，如果继承TabActivity，并且通过getTabHost()方法来获取TabHost，那么三者的ID必须是android.R.id.tabhost、android.R.id.tabs、android.R.id.tabcontent，如果继承Activity，可以通过findViewById来获取这三个组件，此时ID可自定义。
