Android - set activity result on activity closed


To start activity for result:

Intent intent = new Intent(MainActivity.this, DetailsActivity.class);
startActivityForResult(intent,EVENT_DETAILS_REQUEST);

In my DetailsActivity, to set result and extras, that can be used in main activity:

@Override
    public void onBackPressed()
    {
        Intent resultIntent = new Intent();
        resultIntent.putExtra("isEdited",isEdited);
        setResult(RESULT_OK,resultIntent);
        finish();
    }

Finally, in MainActivity:

@Override
    protected void onActivityResult(int requestCode, int resultCode, @NonNull Intent data)
{
  switch(requestCode)
  {
    ......
    case EVENT_DETAILS_REQUEST:
    boolean isEdited = data.getBooleanExtra("isEdited", false);
    .......
    break;

  }

}

This is fine as long as user is using "Back" hardware (or system navbar) button to close DetailsActivity. If user tap "Back" arrow at the top of the activity to close activity, onBackPressed won't be called and onActivityResult data will be null.

I have tried to use onPause, onStop, onFinish instead of onBackPressed to manage it working, but I'm getting data for onActivityResult always null.

What is correct way to solve my problem?


Solution

  • @Override
    public boolean onOptionsItemSelected(MenuItem item)
    {
        switch (item.getItemId())
        {
            case android.R.id.home:
                onBackPressed();
                return true;
    
            default:
                return super.onOptionsItemSelected(item);
        }
    }
    

    Override this method in your detail activity... and this code
