Android选项卡TabHost功能和用法

1、布局文件

<TabHost xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@android:id/tabhost" android:layout_weight="1" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.helloword.TabActivity" >

    <LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">
        
        <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="match_parent" android:layout_height="match_parent">
            </FrameLayout>
            
    </LinearLayout>

</TabHost>

tab1.xml 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tab1" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" >
    
    <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:text="左边 tab"/>

</LinearLayout>

tab2.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tab2" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" >
    
    <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:text="right tab"/>

</LinearLayout>

2、Activity 

package com.example.helloword; import android.app.Activity; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.widget.TabHost; public class TabActivity extends Activity  implements View.OnClickListener{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_tab); TabHost tabHost = findViewById(android.R.id.tabhost); tabHost.setup(); LayoutInflater inflater = LayoutInflater.from(this); inflater.inflate(R.layout.tab1, tabHost.getTabContentView()); inflater.inflate(R.layout.tab2, tabHost.getTabContentView()); tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("left").setContent(R.id.tab1)); tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("right").setContent(R.id.tab2)); } @Override public void onPointerCaptureChanged(boolean hasCapture) { // TODO Auto-generated method stub
 } @Override public void onClick(View arg0) { // TODO Auto-generated method stub
 } }
