TabHost使用（二）

第一步：布局文件

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:id="@+id/tab1"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">
    <TextView
   		android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:text="This is one tab"/>
    </LinearLayout>
    
     <LinearLayout
     	android:id="@+id/tab2"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">
    <TextView
   		android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:text="This is two tab"/>
    </LinearLayout>
     <LinearLayout
     	android:id="@+id/tab3"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">
    <TextView
   		android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:text="This is three tab"/>
    </LinearLayout>
</TabHost>

 

第二步：测试类

public class TabHostTestActivity extends TabActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TabHost tabHost=getTabHost();
        //解析布局文件
        LayoutInflater.from(this).inflate(R.layout.main, tabHost.getTabContentView(), true);
        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("tab1").setContent(R.id.tab1));
        tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("tab2").setContent(R.id.tab2));
        tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("tab3").setContent(R.id.tab3));
        tabHost.setCurrentTab(1);
    }
}
