Android选项卡TabHost功能和用法

1、布局文件

1<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
2    xmlns:tools="http://schemas.android.com/tools"
3    android:id="@android:id/tabhost"
4    android:layout_weight="1"
5    android:layout_width="match_parent"
6    android:layout_height="match_parent"
7    tools:context="com.example.helloword.TabActivity" >
8
9    <LinearLayout 
10        android:orientation="vertical"
11        android:layout_width="match_parent"
12        android:layout_height="match_parent">
13        
14        <TabWidget
15            android:id="@android:id/tabs"
16            android:layout_width="match_parent"
17            android:layout_height="wrap_content"/>
18            
19            <FrameLayout
20                android:id="@android:id/tabcontent"
21                android:layout_width="match_parent"
22                android:layout_height="match_parent">
23            </FrameLayout>
24            
25    </LinearLayout>

5import android.os.Bundle;
6import android.view.LayoutInflater;
7import android.view.View;
8import android.widget.TabHost;
9
10public class TabActivity extends Activity  implements View.OnClickListener{
11
12    @Override
13    protected void onCreate(Bundle savedInstanceState) {
14        super.onCreate(savedInstanceState);
15        setContentView(R.layout.activity_tab);
16        
17        TabHost tabHost = findViewById(android.R.id.tabhost);
18        tabHost.setup();
19        
20        LayoutInflater inflater = LayoutInflater.from(this);
21        
22        inflater.inflate(R.layout.tab1, tabHost.getTabContentView());
23        inflater.inflate(R.layout.tab2, tabHost.getTabContentView());
24        
25        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("left").setContent(R.id.tab1));
26        
27        tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("right").setContent(R.id.tab2));
28        
29        
30    }
31
32    @Override
33    public void onPointerCaptureChanged(boolean hasCapture) {
34        // TODO Auto-generated method stub
35        
36    }
37
38    @Override
39    public void onClick(View arg0) {
