I'm trying to resolve a larger problem that relates to animating a nested fragment so I created a separate project and am trying to tackle it in modules.
The first part is toggling visibility within the childFragment
- I've been trying different types of code and I'm not sure why when I add layoutReturn.setVisibility(View.INVISIBLE);
The parent fragment is hidden. Yet when I add this line after inserting the child fragment:
@Override
public void onClick(View v) {
//layoutReturn.setVisibility(View.INVISIBLE);
FragmentManager childFrag = getFragmentManager();
FragmentTransaction childFragTrans = childFrag.beginTransaction();
addressCard_fragment addressCardChild = new addressCard_fragment();
childFragTrans.add(R.id.bottom_row_fragment_container, addressCardChild);
//childFragTrans.setCustomAnimations(R.animator.slide_in_card, R.animator.slide_out_card);
childFragTrans.commit();
Toast.makeText(getActivity().getBaseContext(), "yo", Toast.LENGTH_SHORT).show();
layoutReturn.setVisibility(View.INVISIBLE);
}
The change has no effect. The parent fragment remains visible, the Toast appears but the childFragment
remains unseen. Any help would be greatly appreciated!
Main Activity:
public class MainActivity extends AppCompatActivity {
private topRow_fragment fragmentTopRow;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
fragmentTopRow = new topRow_fragment();
}
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.top_row_fragment_container, fragmentTopRow);
fragmentTransaction.commit();
}}
parentFragment class:
public class topRow_fragment extends Fragment implements View.OnClickListener{
ImageButton btn;
View layoutReturn;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
layoutReturn = inflater.inflate(R.layout.firstrow_fragment, container, false);
btn = (ImageButton) layoutReturn.findViewById(R.id.imageLeft);
btn.setOnClickListener(this);
return layoutReturn;
}
@Override
public void onClick(View v) {
//layoutReturn.setVisibility(View.INVISIBLE);
FragmentManager childFrag = getFragmentManager();
FragmentTransaction childFragTrans = childFrag.beginTransaction();
addressCard_fragment addressCardChild = new addressCard_fragment();
childFragTrans.add(R.id.bottom_row_fragment_container, addressCardChild);
//childFragTrans.setCustomAnimations(R.animator.slide_in_card, R.animator.slide_out_card);
childFragTrans.commit();
Toast.makeText(getActivity().getBaseContext(), "yo", Toast.LENGTH_SHORT).show();
layoutReturn.setVisibility(View.INVISIBLE);
}}
childFragment class is just the typical onCreateView method.
Update01: When I use getChildFragmentManager I receive a massive error that begins with 09-14 22:54:34.933 20795-20795/com.example.bryanjordan.nestedfragmentstest E/FragmentManager: No view found for id 0x7f0c0060 (com.example.bryanjordan.nestedfragmentstest:id/bottom_row_fragment_container) for fragment addressCard_fragment{7d09836 #0 id=0x7f0c0060}
and is summarised with: java.lang.IllegalArgumentException: No view found for id 0x7f0c0060 (com.example.bryanjordan.nestedfragmentstest:id/bottom_row_fragment_container) for fragment addressCard_fragment{7d09836 #0 id=0x7f0c0060}

Both your top_row_fragment_container
and bottom_row_fragment_container
containers are in MainActivity. Then it is not prbably nested fragment.
Nested fragment mean Fragment inside Fragment.
You have wrap_content as container height.
android:layout_height="wrap_content"
Set some height to get both of your fragment visible.
Remove layoutReturn.setVisibility(View.INVISIBLE);
from your code.
