I've seen this mentioned in a couple of places but cant quite work out how to implement it as there are no example online, I'm wondering whether I've misinterpreted its meaning.
the android developer link for addOnBackPressedCallback
I was wondering whether this means I can add a callback inside my fragment to pick up the onBackPressed() before it hits the activity.
In my fragment I've implemented
implements OnBackPressedCallBack
then implemented the method
@Override
public boolean handleOnBackPressed()
Log.d(TAG, "handleOnBackPressed: hello");
return true;
But its not picking it up and going straight to main activity onBackPressed().
I read on further and saw that My fragment needed to extend from FragmentActivity
public class MainExampleFragment extends FragmentActivity implements View.OnClickListener, OnBackPressedCallback {
and instead of
appCompatActivity.getSuppportFragmentManager
to call
FragmentActivity.getSupportFragmentManager
instead, but this throws and error in the Fragment.newInstance method when trying to set the bundle.
Has anyone info on doing this please thanks
