Tabhost的简单使用

建立主布局文件：

//其中红色为必选项，且注意id的写法

xml version= "1.0" encoding= "utf-8" ?>
< RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android"
    android :layout_width= "match_parent"
    android :layout_height= "match_parent" >

   < TabHost
       android :layout_width= "match_parent"
       android :layout_height= "wrap_content"
       android :id= "@+id/TabHost1" >
       < LinearLayout
           android :layout_width= "match_parent"
           android :orientation= "vertical"
           android :layout_height= "wrap_content" >

           < TabWidget
               android :layout_width= "match_parent"
               android :layout_height= "wrap_content"
               android :id= "@android:id/tabs" >
           TabWidget >

           < FrameLayout
               android :layout_width= "match_parent"
               android :layout_height= "match_parent"
               android:id= "@android:id/tabcontent" >
           FrameLayout >

       LinearLayout >

   TabHost >

RelativeLayout >

//设置标签页布局，注意红色和蓝色的标记

标签页布局1：tab1_layout

< LinearLayout android :layout_width= "match_parent"
    android :layout_height= "match_parent"
    android :orientation= "vertical"
    android:id= "@+id/tabLinLayout1"
    xmlns: android = "http://schemas.android.com/apk/res/android" >

    < Button
        android :layout_width= "match_parent"
        android :layout_height= "wrap_content"
        android :id= "@+id/btnBack"
        android :text= "返回" />

LinearLayout >

标签页布局2：tab2_layout

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:id="@+id/tabLinLayout2" >

    < Button
        android :layout_width= "match_parent"
        android :layout_height= "wrap_content"
        android :id= "@+id/btn2Back"
        android :text= "back" />

LinearLayout >

在java代码中的使用：

TabHost tabHost = (TabHost) findViewById(R.id. TabHost1 );
tabHost.setup();    //启用

//声明布局文件，通过选取布局文件名方式
LayoutInflater layoutInflater = LayoutInflater.from( this );
layoutInflater.inflate(R.layout. tab1_layout ,tabHost.getTabContentView());
layoutInflater.inflate(R.layout. tab2_layout ,tabHost.getTabContentView());

//为布局设置id，配置标签时用id与标签绑定
tabHost.addTab(tabHost.newTabSpec( "tab1" ).
        setIndicator( "标签1").setContent(R.id. tabLinLayout1 ));
tabHost.addTab(tabHost.newTabSpec( "tab2" ).

        setIndicator( "标签2").setContent(R.id. tabLinLayout2));
