call custom Activity as startActivityForResult

Question

I am starting an Activity for result as

startActivityForResult(new Intent(this,ActivityA.class),REQUEST_CODE)

ActivityA is started. There is a gridview on ActivityA, I want to get the position of selected image in method onActivityResult(int requestCode, int resultCode, Intent data) of caller Activity but I am not getting the way to do that

Answer 1

In Activity A,

onItemClick() of GridView

//create a new intent...
Intent intent = new Intent();
intent.putInt("position",position);
setResult(RESULT_OK,intent);
//close this Activity...
finish();

in Caller Activity,

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent){
        super.onActivityResult(requestCode, resultCode, intent);
        Bundle extras = intent.getExtras();
        if(extras != null)
        int position = extras.getInt("position");
    }
