安卓Viewpager之PagerTitleStrip和PagerTabStrip使用

PagerTabStrip 和 PagerTitleStrip 都是安卓ViewPager组件的一个“卡片”，效果如下图。

 

PagerTitleStrip 是不可交互的，图中顶部那个就是(只能展示不能点击)；PagerTabStrip 是可交互的，能点击底部那个tab跳转viewpager的pager。下面是主要代码

<pre name="code" class="html"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center" >
        <!-- 顶部的 标题 tip -->
        <android.support.v4.view.PagerTitleStrip
            android:id="@+id/pagertitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="top" />
    </android.support.v4.view.ViewPager>

</LinearLayout>

下面是MainActivity的java代码。

  * PagerTabStrip(可交互的，就是能点击跳转page) 就是比PagerTitleStrip多了个下条。。。 看api：http://blog.toolib.net/reference/android/support/v4/view/PagerTabStrip.html 简单
  * PagerTitleStrip(不可交互的，就是个title点击不会跳转page) 用户：http://www.open-open.com/lib/view/open1350291294336.html
