Question

I have several intent using startActivityforResult() to launch. I want to receive several feedbacks. How can I write onActivityResult() for each startActivityforResult()?

Answer 1

You can pass in the requestCode as second argument to startActivityForResult. This integer value will be return to you in onActivityResult as requestCode.

Say you calling with different request codes.

 startActivityForResult(i1, 1);

 startActivityForResult(i2, 2);

Then your onActivityResult looks like:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  switch (requestCode) {
     case 1:
       // do what u hv to do for first start activity
     break;
     case 2:
       // for second start activity
     break;
  }
}

In Activity 2 which is launched by you use following apis to return the data:

public final void setResult (int resultCode)
public final void setResult (int resultCode, Intent data) // If you want to pass some data
