在android中单击任何选项卡时启动主活动

我有三个包含子活动的选项卡，问题是当我单击其中任何一个选项卡时，它都不会显示主活动。我如何在这三个选项卡栏中显示主活动…有人对此有解决方案吗

提前。。 ：）

Tabmain TabActivity

    TabHost tabHost = getTabHost();
    TabSpec HomeSpec = tabHost.newTabSpec("Home");
    HomeSpec.setIndicator("Home", getResources().getDrawable(R.drawable.home));
    Intent HomeIntent = new Intent(this, HomeMediator.class);
    HomeSpec.setContent(HomeIntent);

    TabSpec SearchSpec = tabHost.newTabSpec("Search");
    SearchSpec.setIndicator("Search", getResources().getDrawable(R.drawable.search));
    Intent songsIntent = new Intent(this, SearchMediator.class);
    SearchSpec.setContent(songsIntent);

    TabSpec TreeInfoSpac = tabHost.newTabSpec("Tree Info");
    TreeInfoSpac.setIndicator("Botanical Name", getResources().getDrawable(R.drawable.carrot));
    Intent videosIntent = new Intent(this, BotaniacalMediator.class);
    TreeInfoSpac.setContent(videosIntent);

    tabHost.addTab(HomeSpec);
    tabHost.addTab(SearchSpec);
    tabHost.addTab(TreeInfoSpac);
    tabHost.setOnTabChangedListener(new OnTabChangeListener() {

        @Override
        public void onTabChanged(String tabId) {
            // TODO Auto-generated method stub

        }
    });

禁忌群体活动

private ArrayList<String> mIdList;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (mIdList == null) {
        mIdList = new ArrayList<String>();

    }
}


public void finishFromChild(Activity child) {
    LocalActivityManager manager = getLocalActivityManager();
    int index = mIdList.size() - 1;

    if (index < 0) {
        finish();
        return;
    }

    manager.destroyActivity(mIdList.get(index), true);
    Log.i("Activity Finish:", manager.getCurrentId());
    mIdList.remove(index);
    index--;
    String lastId = mIdList.get(index);
    Intent lastIntent = manager.getActivity(lastId).getIntent();
    Window newWindow = manager.startActivity(lastId, lastIntent);
    setContentView(newWindow.getDecorView());
}

public void startChildActivity(String Id, Intent intent) {

    Window window = getLocalActivityManager().startActivity(Id,
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
    if (window != null) {
        mIdList.add(Id);
        setContentView(window.getDecorView());
        Log.i("Activity Start:", getLocalActivityManager().getCurrentId());
    }
}

我不太清楚你的意思，但要使用

OnTabListener

启动意图

Intent main = new Intent (yourclass.this, MainClass.class);
startActivity(main);

---

您可以在第一个tabspec中进行设置，如下所示

  Intent HomeIntent = new Intent(this, MainClass.class);
  HomeSpec.setContent(HomeIntent);

---

请提供您正在使用的代码qtn有点模糊

Intent main = new Intent (yourclass.this, MainClass.class);
startActivity(main);

  Intent HomeIntent = new Intent(this, MainClass.class);
  HomeSpec.setContent(HomeIntent);
