单标签Android的多种活动

问题描述

限时删除！！

在我的应用程序，我想从使用意图的选项卡按钮打开活动。而不是开在同一个选项卡，但新的活动覆盖整个屏幕和选项卡不可见萦绕。我如何打开在同一个标​​签一个以上的活动。

In my application I am trying to open an activity from a button in tab using intent. But instead of opening in the same tab the new activity covers the entire screen and the tabs are no linger visible.. How can I open more than one activity in the same tab..

下面code是我的主类的：

The following code is of my main class:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    TabHost tabHost = getTabHost();
    tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("OPT").setContent(new Intent(this, TabGroup1Activity.class)));
    tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("EDIT").setContent(new Intent(this, TabGroup2Activity.class)));
    tabHost.setCurrentTab(1);
}

下面是TabGroupActivity的code：

The following is the code of TabGroupActivity:

public class TabGroupActivity extends ActivityGroup{

ArrayList<String> list;
Window window;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    if(list.equals(null))
    {
        list = new ArrayList<String>();
    }
}

@Override
public void finishFromChild(Activity child)
{
    LocalActivityManager manager = getLocalActivityManager();
    int index = list.size() -1;
    if(index < 1)
    {
        finish();
        return;
    }
    manager.destroyActivity(list.get(index), true);
    list.remove(index);
    index--;
    String lastId = list.get(index);
    Intent in = manager.getActivity(lastId).getIntent();
    window = manager.startActivity(lastId, in);
    setContentView(window.getDecorView());
}

public void startChildActivity(String Id, Intent intent)
{
    window = getLocalActivityManager().startActivity(Id, intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
    if(window != null)
    {
        list.add(Id);
        setContentView(window.getDecorView());
    }
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
    if(keyCode == KeyEvent.KEYCODE_BACK)
        return true;
    return super.onKeyDown(keyCode, event);
}

@Override
public boolean onKeyUp(int keyCode, KeyEvent event)
{
    if(keyCode == KeyEvent.KEYCODE_BACK)
    {
        onBackPressed();
        return true;
    }
    return super.onKeyUp(keyCode, event);
}

@Override
public void onBackPressed()
{
    int length = list.size();
    if(length > 1)
    {
        Activity current = getLocalActivityManager().getActivity(list.get(length - 1));
        current.finish();
    }
}
}

在$ C $下TabGroup1Activity的TabGroup2Activity也有同样的code：

The code for TabGroup1Activity the TabGroup2Activity also having the same code:

public class TabGroup1Activity extends TabGroupActivity{
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    startChildActivity("TestClass", new Intent(this,TestClass.class));
}
}

code为TestClass的活动：

Code for the TestClass activity:

public class TestClass extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.newview);
}
}
