目前我在 Android 应用程序中工作，使用 Tabbar 创建五个选项卡，如 1、2、3、4 和 5。第一个选项卡使用 ListActivity 创建 ListView，当我从 ListView 中选择 ListItem 时，ListItem 值转到第三个选项卡，并且我在第三个选项卡中得到了很好的值，但问题是从第一个选项卡到第三个选项卡的值传递，当时只选择了第一个选项卡，但我想选择第三个选项卡。如何解决这个问题，请帮助我。

源代码供您参考：
第一个标签：
@Override
protected void onListItemClick(ListView l, final View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
String SelectedItem = l.getItemAtPosition(position).toString();
System.out.println("Selected Item: "+ SelectedItem);
System.out.println("position Item: "+ position);
String SelectedPhoneNumber = phoneNumber.get(position);
System.out.println("SelectedPhoneNumber " + SelectedPhoneNumber);
// Using TabGroupActivity, so
Intent i = new Intent(getParent(), 3rdTab.class);
i.putExtra("DestinationNumber", SelectedPhoneNumber);
TabGroupActivity parentActivity = (TabGroupActivity)getParent();
parentActivity.startChildActivity("Sample", i);
}
