Question

在我的一个应用程序中，我在{{tabactivity}}和{{activitygroup}}的帮助下使用标签栏在每个屏幕中显示标签栏。

我想检测已选择的标签上的第二次点击，并实现类似于iPhone UITabbar的功能。第二次点击它将进入初始活动。

public class Tabmanagement extends TabActivity{

public static Button back;
public static TextView text;
public static Button next;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
    setContentView(R.layout.tabmanagement);

    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    Resources res = getResources();
    TabHost tabHost = getTabHost();
    TabHost.TabSpec spec;
    Intent intent;

    getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.windowstitle);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

    back=(Button)findViewById(R.id.Btn_Back);
    text = (TextView) findViewById(R.id.Text_Title);
    next=(Button)findViewById(R.id.Btn_Search);  


    spec = tabHost  .newTabSpec("tab1")
    .setIndicator("Topics",res.getDrawable(R.drawable.topics))
    .setContent(new Intent(this,FirstGroup.class)
    .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
    tabHost.addTab(spec);




    spec = tabHost  .newTabSpec("tab2")
    .setIndicator("Posts",res.getDrawable(R.drawable.post))
    .setContent(new Intent(this,SecondGroup.class)
    .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
    tabHost.addTab(spec);



    intent = new Intent().setClass(this, ThirdGroup.class);

    spec = tabHost  .newTabSpec("tab3")
                    .setIndicator("Response",res.getDrawable(R.drawable.response))
                    .setContent(intent);

    tabHost.addTab(spec);


    intent = new Intent().setClass(this, FourthGroup.class);

    spec = tabHost  .newTabSpec("tab4")
                    .setIndicator("Settings",res.getDrawable(R.drawable.settings))
                    .setContent(intent);

    tabHost.addTab(spec);
    tabHost.setCurrentTab(0);

    }

}

我认为这就是你要找的东西。基本上从TabHost中获取TabWidget，并在视图上设置正确的侦听器。
