OnBackpress Tabgroupactivity не работает, если идентификатор клавиатуры открыт в любой деятельности

Я использую Tabgroupactivity в моем приложении, если я использовал editbox в своем приложении. Когда я нажимаю на клавиатуре редактирования, открывается. На этом tym, если если нажать кнопку назад, мое приложение будет два раза назад. Ниже приведен мой код для активности tabgroup.

public class TabGroupActivity extends ActivityGroup {

private ArrayList<String> mIdList;

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


/**
 * This is called when a child activity of this one calls its finish method. 
 * This implementation calls {@link LocalActivityManager#destroyActivity} on the child activity
 * and starts the previous activity.
 * If the last child activity just called finish(),this activity (the parent),
 * calls finish to finish the entire group.
 */

//  public void finishFromChild(Activity child) {
//  
//      LocalActivityManager manager = getLocalActivityManager();
//      int index = mIdList.size()-1;
//      
//      if (index < 1) {
//          finish();
//          return;
//      }
//          
//      manager.destroyActivity(mIdList.get(index), true);
//      mIdList.remove(index); index--;
//      String lastId = mIdList.get(index);
//      Intent lastIntent = manager.getActivity(lastId).getIntent();
//      Window newWindow = manager.startActivity(lastId, lastIntent);
//      setContentView(newWindow.getDecorView());
//  }
