I recently updated a project that I completed a couple of years ago. The application has a fragment and a sliding pane with a list of items, pressing on which triggers a certain action and closes the pane. The pane is also closed once the fragment is open.
public View onCreateView(@NonNull LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
performanceViewModel = new ViewModelProvider(this).get(Model_Performance.class);
View root = inflater.inflate(R.layout.performance_fragment_layout, container, false);
//setHasOptionsMenu(true); //DEPRECATED
// Create a Sliding Pane
slidingPane = root.findViewById(R.id.performance_sliding_pane_layout);
slidingPane.addPanelSlideListener(new SlidingPaneLayout.SimplePanelSlideListener(){
@Override
public void onPanelOpened(View panel) {
//Toast.makeText(panel.getContext(), "Opened", Toast.LENGTH_SHORT).show();
panelOpened();
}
@Override
public void onPanelClosed(View panel) {
//Toast.makeText(panel.getContext(), "Closed", Toast.LENGTH_SHORT).show();
panelClosed();
}
@Override
public void onPanelSlide(View view, float v) { }
});
if (slidingPane != null) {
if (slidingPane.isOpen())
{
Log.i("SlidePane","is closing........");
slidingPane.closePane();
}
}
view = root;
// +++++++++++++++++++++++++++++++
// Left sliding panel
// +++++++++++++++++++++++++++++++
// Lookup the recyclerview in activity layout
rvPerformance = root.findViewById(R.id.rvPerformanceLeft);
adapter = new PerformanceTableAdapter(appSingleton.getListOfPirepItemsShared(), this);
// Attach the adapter to the recyclerview to populate items
rvPerformance.setAdapter(adapter);
// Set layout manager to position the items
rvPerformance.setLayoutManager(new LinearLayoutManager(root.getContext()));
// Add horizontal dividers
rvPerformance.addItemDecoration(new DividerItemDecoration(root.getContext(), DividerItemDecoration.HORIZONTAL));
txtPerformance = root.findViewById(R.id.txtPerformance);
return root;
}
The problem is that slidingPane.closePane(); is never called. This is the message that I get in the console:
I/SlidePane: is closing........
W/System: A resource failed to call close.
An interesting thing is that when I try to close it with a menu button, like this:
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
MenuHost menuHost = requireActivity();
menuHost.addMenuProvider(new MenuProvider() {
@Override
public void onCreateMenu(@NonNull Menu menu, @NonNull MenuInflater menuInflater) {
menuInflater.inflate(R.menu.top_nav_menu_performance, menu);
}
@Override
public boolean onMenuItemSelected(@NonNull MenuItem menuItem) {
if(menuItem.getItemId()==android.R.id.home) {
// Opening and closing the Sliding Pane
if (slidingPane != null) {
if (!slidingPane.isOpen()) { slidingPane.openPane(); }
else { slidingPane.closePane(); }
}
}
return true;
}
}, getViewLifecycleOwner(), Lifecycle.State.RESUMED);
}
... the pane gets closed just fine. Everything used to work before.
Thanks in advance!
EDIT:
The closePane(); is only not called inside onCreateView or onViewCreated in the fragment. It is called just fine from a button click. This is driving me crazy... Just in case, this is the layout:
