由于提前

推荐答案

样本实施例：
这里考虑三个选项卡
首先在MainActivity.java

Sample Example : Consider three tabs here First in MainActivity.java

public class MainActivity extends TabActivity {

    private static final String TAB1 = "TAB1";
    private static final String TAB2 = "TAB2";
    private static final String TAB3 = "TAB3";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TabHost tabHost = getTabHost();


        TabSpec tab1 = tabHost.newTabSpec(TAB1);
        tab1.setIndicator(TAB1);
        Intent Intent1 = new Intent(this, Tab1.class);
        tab1.setContent(Intent1);


        TabSpec tab2 = tabHost.newTabSpec(TAB2);
        tab2.setIndicator(TAB2);
        Intent Intent2 = new Intent(this, Tab2.class);
        tab2.setContent(Intent2);


        TabSpec tab3 = tabHost.newTabSpec(TAB3);
        tab3.setIndicator(TAB3);
        Intent Intent3 = new Intent(this, Tab3.class);
        tab1.setContent(Intent3);


        tabHost.addTab(tab1); 
        tabHost.addTab(tab2); 
        tabHost.addTab(tab3); 
    }
}

main.xml中

main.xml

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="64dp" />

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"/>
    </LinearLayout>
</TabHost>

然后三类Tab1.java，Tab2.java和Tab3.java
三和XML文件的类。

Then three classes Tab1.java , Tab2.java and Tab3.java And three xml files to that classes.

尝试一下，说。
