Re-loading Fragment from inside itself

Question

I have been trying to figure out how I would be able to refresh my Fragment from a menu button that is defined inside the Fragment. I have looked at this question here but I was hoping for a more detailed example on how I would be able to achieve this. Any help or Guidance would be appreciated, thanks. ``` @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.clear_cache: mImageFetcher.clearCache(); Toast.makeText(getActivity(), R.string.clear_cache_complete_toast, Toast.LENGTH_SHORT).show(); break; case R.id.random: //Reload the fragment from here getActivity().getSupportFragmentManager().beginTransaction() .replace(R.id.gridView, new Fragment3()) .commit(); return true; } return super.onOptionsItemSelected(item); ``` XML: ``` ``` Crashes with: ``` 12-04…

Accepted Answer

Inside Fragment put these:

```
private Callbacks mCallbacks;

public interface Callbacks {
        //Callback for when button clicked.
        public void onButtonClicked();
}

@Override
public void onAttach(Activity activity) {
        super.onAttach(activity);
        // Activities containing this fragment must implement its callbacks
        mCallbacks = (Callbacks) activity;

}
```

In onOptionsItemSelected change to

```
case R.id.random:

mCallbacks.onButtonClicked();
break;
```

Make your FragmentActivity to implements YourFragment.Callbacks :

```
public class YourActivityName extends FragmentActivity implements YourFragment.Callbacks
```

Inside the FragmentActivity containing the Fragment add this:

```
    @Override
    public void onButtonClicked() {
        getSupportFragmentManager().beginTransaction()
        .replace(R.id.gridView, new Fragment3())
        .commit();

}
```
