我做了并运行了例子.但我接受了错误.

Error: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.tabmenu/com.example.tabmenu.MainActivity: java.lang.IllegalArgumentException: you must specify a way to create the tab indicator.

mainActivity.java

@SuppressWarnings("deprecation")
public class MainActivity extends TabActivity {

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

        TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);

        TabSpec tab1 = tabHost.newTabSpec("First Tab");
        TabSpec tab2 = tabHost.newTabSpec("Second Tab");
        TabSpec tab3 = tabHost.newTabSpec("Third Tab");

        tab1.setIndicator("Tab1");
        tab1.setContent(new Intent(this,Tab1Activity.class));

        tab1.setIndicator("Tab2");
        tab1.setContent(new Intent(this,Tab2Activity.class));

        tab1.setIndicator("Tab3");
        tab1.setContent(new Intent(this,Tab3Activity.class));

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