推荐答案

我只是有这个同样的问题，我通过调用解决了当前活动的onBack pressed从的ActivityGroup：

I just had this same problem and I solved it by calling the current activity's onBackPressed from the ActivityGroup:

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

IDLIST是活动的活动组在列表中。

idList is a list of activities in the activity group.
