我有四个活动说A,B,C和D 我的情况是A将通过startActivityForResult启动b活动。
I have Four activity say A, B, C and D My situation is A will start the activity B by startActivityForResult.
startActivityForResult(new Intent(this,B.class),ONE);
在其他情况下,我将与其他情况B点。像
In other situation i will B with other situation. like
startActivityForResult(new Intent(this,B.class),TWO);
在B I需要检查我需要调用C或D取决于请求code。如果即ONE需要启动C否则ð 所以,我需要知道谁(在这里B)检查请求code在孩子活动 或者换句话说,我想要得到什么要求code没有B则在b活动 在此先感谢
In B i need to check I need to call C or D depending requestCode. I.e if ONE need to start C else D So i need to know who to check the requestCode in the child Activity (B here ) Or in other words I want to get with what request code did B started in the Activity B Thanks in advance
您可以把多余的传递请求code。
You can pass request code by put extra.
intent.putExtra("requestCode", requestCode);
或者,如果你已经使用 startActivityForResult
很多次,那么比编辑每个较好,可以覆盖
的 startActivityForResult
在活动
,添加code有这样
Or if you have used startActivityForResult
many times, then better than editing each, you can override
the startActivityForResult
in your Activity
, add you code there like this
@Override
public void startActivityForResult(Intent intent, int requestCode) {
intent.putExtra("requestCode", requestCode);
super.startActivityForResult(intent, requestCode);
}
因此,有没有需要修改所有startActivityForResult 希望它帮助你。
So there is no need to edit all your startActivityForResult Hope it helped you
