I am using code from a lot of different sources and stringing things together, so I know I am doing something wrong, but I cant seem to find it.
Thanks in advance.
UPDATE:
The Resource file for the Activity is as follows:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MessageSelectionListActivity" >
<TextView
android:id="#+id/smsPageTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/sms_page_title"
android:textSize="20sp" />
<TextView
android:id="#+id/smsPageInstructions"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/smsPageTitle"
android:layout_below="#+id/smsPageTitle"
android:text="#string/sms_page_instructions"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="15sp" />
<Button
android:id="#+id/makeExcelFileButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/smsPageInstructions"
android:layout_alignParentBottom="true"
android:layout_alignRight="#+id/smsPageInstructions"
android:text="#string/make_excel_file" />
<ListView
android:id="#+id/smsListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/makeExcelFileButton"
android:layout_alignLeft="#+id/makeExcelFileButton"
android:layout_below="#+id/smsPageInstructions" />
And for the row layout is as follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip" >
<CheckBox
android:id="#+id/item_check_box"
android:layout_width="wrap_content"
android:layout_height="fill_parent" />
<TextView
android:id="#+id/item_title"
android:layout_width="fill_parent"
android:layout_height="26dip"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_toRightOf="#id/item_check_box"
android:singleLine="true" />
<TextView
android:id="#+id/item_body"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_toRightOf="#id/item_check_box"
android:layout_below="#id/item_title" />
</RelativeLayout>

So I was able to fix the problem.
here is how. The first message in the trace gave me the clue.
04-08 13:06:49.699: E/AndroidRuntime(2616): FATAL EXCEPTION: main 04-08 13:06:49.699: E/AndroidRuntime(2616): android.content.res.Resources$NotFoundException: Resource ID #0x7f090006 type #0x12 is not valid
The the resource with ID 0x7f090006 is invalid. so when I traced it back to the code, I had used the Resource ID instead of the resource name (R.layout.XXXXXX). changing it to that resolved the issue.

I cant call activity function from fragment in android studio

I have two scripts
Activity:
public class HomeActivity extends AppCompatActivity {
public void Init()
{
//Do something
}
}
Fragment:
public class HomeFragment extends Fragment {
private FragmentHomeBinding binding;
#Override
public View onCreateView(#NonNull LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
HomeViewModel homeViewModel =
new ViewModelProvider(this).get(HomeViewModel.class);
binding = FragmentHomeBinding.inflate(inflater, container, false);
View root = binding.getRoot();
HomeActitvity homeActitvity = new HomeActivity()
homeActivity.Init()
return root;
}
}
When I run app I get this errors and app closes, but when I comment homeActivity.Init() app opens

thank you to all the helpers
can you please share the crashing error? It's hard to figure out the error. If you can also add how to reproduce the crash it can be very helpful
You forgot to initialize NavHostFragent
so kindly Initiliaze In your OnCreate
NavHostFragment navHostFragment = (NavHostFragment) getSupportFragmentManager()
.findFragmentById(R.id. fragmentContainerView);
NavController navController = navHostFragment.getNavController();
and for the navigate one fragment to another fragment use navigate
homeBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {navController.navigate(R.id. action_startFragment_to_registerFragment
}
});)

Two recyclerview not scrollable in one layout

I created a View that has two recyclerviews inside.
Everything works correctly but I get that the two recyclerviews are scrollable.
I would like the two recyclerview to be shown in its maximum length to show all lines and for the scrolling of the view to work directly
if I set android: nestedScrollingEnabled = "false" the recyclerview is not shown totally long
what do i have to change?
Thanks

You have to use only one RecyclerView and use the type to manage which card you want to recall
public class RecyclerViewAdapterClasseursDocs extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private final List<Document> documents;
private final List<Classeur> classeurs;
private final Context context;
public RecyclerViewAdapterClasseursDocs(List<Classeur> classeurs, List<Document> documents, Context context) {
this.classeurs = classeurs;
this.context = context;
this.documents = documents;
}
#NonNull
#Override
public RecyclerView.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {

return new ViewHolderClasseur(LayoutInflater.from(context.getApplicationContext()).inflate(R.layout.classeur, parent, false));
}
return new ViewHolderDoc(LayoutInflater.from(context.getApplicationContext()).inflate(R.layout.docs, parent, false));

Please tell me what I missed. Thank you.
Check all the ids in the xml files and correct their name in java.
It seems like you are referencing an id of another xml file thats not associated with this activity like you might be refering a username field of login xml file in registration activity and vice versa
Nvm, i fixed the problem. There's no problem with the codings just the application is not updated after changes had been made. It is fixed after i clean and rebuild the project. Thank you .

java.lang.IllegalStateException: Required view not found even after setContentView()

I am facing a weird problem related to view not found but everything seems to be right with the code (at least to me). Infact the program was working fine till some time back. I am not sure what change that i made causing this issue. Could anyone of you point me the problem? Thank you.
