当我试图让我的活动选项卡主机它显示了你忘了叫公共无效设置（LocalActivityManager的ActivityGroup）？

 公共类MainActivity扩展FragmentActivity {
    私人资源资源;
    私人TabHost tabHost;

    @覆盖
    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.activity_main）;

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

            tabHost.setup（）;

        RES = getResources（）;

        意图int​​entContact =新意图（）。setClass（这一点，
                tabOne_Activity.class）;
        则tabspec tabSpecContact = tabHost.newTabSpec（聊天）
                .setIndicator（，res.getDrawable（R.drawable.ic_launcher））
                .setContent（intentContact）;
        tabHost.addTab（tabSpecContact）;

        意图int​​entChat =新意图（）setClass（这一点，tabTwo_Activity.class）。
        则tabspec tabSpecChat = tabHost.newTabSpec（聊天）
                .setIndicator（，res.getDrawable（R.drawable.ic_launcher））
                .setContent（intentChat）;
        tabHost.addTab（tabSpecChat）;

        意图int​​entProfile =新意图（）。setClass（这一点，
                tabThree_Activity.class）;
        则tabspec tabSpecProfile = tabHost.newTabSpec（聊天）
                .setIndicator（，res.getDrawable（R.drawable.ic_launcher））
                .setContent（intentProfile）;
        tabHost.addTab（tabSpecProfile）;

        tabHost.setCurrentTab（2）;


    }
}
 

解决方案

您要使用tabhost.For，你必须扩展 TabActivity

或

写低于code中的onCreate（）：

  LocalActivityManager mlam =新LocalActivityManager（这一点，假）;
        mlam.dispatchCreate（savedInstanceState）;
        // tabHost = getTabHost（）;
        //tabHost.setup（）;
        tabHost.setup（mlam）;
 

When I am trying to get the tab host in my activity it is showing the error that do you forget to call public void setup(LocalActivityManager activityGroup)?

public class MainActivity extends FragmentActivity {
    private Resources res;
    private TabHost tabHost;

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

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

            tabHost.setup();

        res = getResources();

        Intent intentContact = new Intent().setClass(this,
                tabOne_Activity.class);
        TabSpec tabSpecContact = tabHost.newTabSpec("Chat")
                .setIndicator("", res.getDrawable(R.drawable.ic_launcher))
                .setContent(intentContact);
        tabHost.addTab(tabSpecContact);

        Intent intentChat = new Intent().setClass(this, tabTwo_Activity.class);
        TabSpec tabSpecChat = tabHost.newTabSpec("Chat")
                .setIndicator("", res.getDrawable(R.drawable.ic_launcher))
                .setContent(intentChat);
        tabHost.addTab(tabSpecChat);

        Intent intentProfile = new Intent().setClass(this,
                tabThree_Activity.class);
        TabSpec tabSpecProfile = tabHost.newTabSpec("Chat")
                .setIndicator("", res.getDrawable(R.drawable.ic_launcher))
                .setContent(intentProfile);
        tabHost.addTab(tabSpecProfile);

        tabHost.setCurrentTab(2);


    }
}

You are trying to use tabhost.For that you must extend TabActivity.

OR

Write the below code in onCreate():

LocalActivityManager mlam = new LocalActivityManager(this, false);
        mlam.dispatchCreate(savedInstanceState);
        // tabHost = getTabHost();
        //tabHost.setup();
        tabHost.setup(mlam);
