Fragment_Adapter_Calling.java file
MyStudentAdapterU adp = new MyStudentAdapterU(stuData, getContext());
stdRecyclerView.setAdapter(adp);
stdRecyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
@Override
public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater) {
inflater.inflate(R.menu.search_menu,menu);
MenuItem item=menu.findItem(R.id.search_menu);
SearchView searchView=(SearchView)item.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
adp.getFilter().filter(newText);
return false;
}
});
super.onCreateOptionsMenu(menu, inflater);
}
but when I try to paste the same code in Activity.java file to call adapter, It shows an error "Cannot resolve method 'getFilter' in 'ProviderAdapter' on adapter.getFilter.filter(newText) line;
ProviderAdapter adp=new ProviderAdapter(ProviderActivityList.this,lists);
r1.setAdapter(adp);
r1.setLayoutManager(new LinearLayoutManager(ProviderActivityList.this));
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.search_menu,menu);
MenuItem item=menu.findItem(R.id.search_menu);
SearchView searchView=(SearchView)item.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
adp.getFilter().filter(newText);
return false;
}
});
return super.onCreateOptionsMenu(menu);
}

CodePudding user response:
In the first code snippet, you set adp
to MyStudentAdapterU
which obviously has a getFilter()
method.
In the second code snipper, you set adp
to ProviderAdapter
which obviously does NOT have a getFilter()
method.
