TabHost+ViewPager做能左右滑动的TabHost

先看下布局文件

main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >
<TabHost 
   android:id="@+id/tab_title"
   android:layout_width="match_parent"
   android:layout_height="wrap_content">
   <TabWidget 
       android:id="@android:id/tabs"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"/>
   
   <FrameLayout 
       android:id="@android:id/tabcontent"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:visibility="gone"/>//这个地方一定要设置为gone
</TabHost>
    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        >
       
    </android.support.v4.view.ViewPager>


</LinearLayout>

下边是每页布局文件 view_content.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    
    <ImageView 
        android:id="@+id/image"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:contentDescription="@string/app_name"/>


</LinearLayout>

下边是应用的主要实现文件
