推荐答案

有一个名为PagerSlidingTabStrip库，它正是你想要的：的 https://github.com/astuetz/PagerSlidingTabStrip

There is a library called "PagerSlidingTabStrip" that does exactly what you want: https://github.com/astuetz/PagerSlidingTabStrip

交互式寻呼指示窗口小部件，与ViewPager从Android的支持库。

Interactive paging indicator widget, compatible with the ViewPager from the Android Support Library.

用法

附上PagerSlidingTabStrip小部件在您的视图。这通常应放在靠近它重新presents的ViewPager。

Include the PagerSlidingTabStrip widget in your view. This should usually be placed adjacent to the ViewPager it represents.

<com.astuetz.viewpager.extensions.PagerSlidingTabStrip
   android:id="@+id/tabs"
   android:layout_width="match_parent"
    android:layout_height="48dip" />

在您的onCreate方法（或onCreateView的片段），绑定控件到ViewPager。

In your onCreate method (or onCreateView for a fragment), bind the widget to the ViewPager.

 // Set the pager with an adapter
 ViewPager pager = (ViewPager) findViewById(R.id.pager);
 pager.setAdapter(new TestAdapter(getSupportFragmentManager()));

 // Bind the widget to the adapter
 PagerSlidingTabStrip tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
 tabs.setViewPager(pager);

（可选）如果您使用OnPageChangeListener你的看法寻呼机，你应该设置在窗口小部件，而不是直接在寻呼机。

(Optional) If you use an OnPageChangeListener with your view pager you should set it in the widget rather than on the pager directly.

 // continued from above
 tabs.setOnPageChangeListener(mPageChangeListener);
