试用此代码:

    import android.widget.TabHost.OnTabChangeListener;

/**

 * tabs. It uses this information to perform some custom animations that slide the tabs in and out from left and right.

您可以使用 ViewPager 和页面inder .

与较旧的Android版本以及更多选项.

使用 ViewPagePagerIncicator lib https://github.com/jakewharton/android-viewpagerindicator/

you can done this by using ViewPager and PageIndicator.

for compatibly with older Android versions, and more options.
