tab标签

//tab标签类定义：

public class TabDamoActivity extends TabActivity {
 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setTitle("TabDamoActivity");
        TabHost tabHost=getTabHost();
        LayoutInflater.from(this).inflate(R.layout.testtab,tabHost.getTabContentView(),true);
        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("test1").setContent(R.id.tab1));
        tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("test2").setContent(R.id.tab2));
        tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("test3").setContent(R.id.tab3));
        tabHost.addTab(tabHost.newTabSpec("tab4").setIndicator("test4").setContent(R.id.tab3));
 }
}
//在res里的layout包中的配置xml文件，实现对tab标签内容的编辑

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
  <TextView
    android:id="@+id/tab1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/red"
    android:text="this is the first Tab!!!"/>
   <TextView
    android:id="@+id/tab2"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/blue"

   <TextView
    android:id="@+id/tab3"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/green"
    android:text="this is the third Tab!!!"/>
</FrameLayout>

//配置AndroidManifest.xml文件：

<activity
  android:name=".TabDamoActivity" android:label="tab "/>
