如何处理onActivityResult？

Question

I am blocking in onActivity result.

Activity A startActivityForResult() to Activity B, Some business reason i am removing activity B and moving to till Activity F. From Activity F have to send setResult() to Activity A same time i have to clear stacks while moving to Activity A.

How to handle this scenario?

Answer 1

We can use a flag from Intent class (didn't try myself) - Intent.FLAG_ACTIVITY_FORWARD_RESULT

Right before calling finish() in each of your middle actvities, you must be making a call to startActivity(intent) . Pass this flag to this intent :

showC.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT);

In your last activity, do the regular setResult() ceremony. And then try to get result in your first activity as usual.

Answer 2

using intent start ActivityF and pass result to ActivityA using intent.putExtra

Intent intent = new Intent(ActivityF.this, ActivityA.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("RESULT", "result to ActivityA");
startActivity(intent);
