推荐答案

1-首先，您必须使用 startActivityForResult()

1- First you'll have to start the Activity from your fragment using startActivityForResult()

2-确保在活动的 onActivityResult()方法中调用 super.onActivityResult (如果正在实现)

2- Make sure to call super.onActivityResult in your Activity's onActivityResult() method ( if you're implementing it)

3-在片段中，您只需实现 onActivityResult()并根据需要处理结果

3-Inside your fragment, you just need to implement onActivityResult() and handle the result as you wish
