As you can see below, I have this Fragment layout from my bottom navigator:
So, when application user click on card item from recycle view, I would like to open another fragment over this Search Fragment. I'm trying to to that, but occurs this error:
E/AndroidRuntime: FATAL EXCEPTION: main
Process: mobhair.com.br, PID: 538
java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.support.v7.widget.RecyclerView$ViewHolder.shouldIgnore()' on a null object reference
at android.support.v7.widget.RecyclerView.findMinMaxChildLayoutPositions(RecyclerView.java:4101)
at android.support.v7.widget.RecyclerView.dispatchLayoutStep1(RecyclerView.java:3835)
I really don't know which the problem. Sou could you please help me?
Follow what I have done so far:
Search Fragment:
public class SearchFragment extends Fragment {
private SearchViewAdataper searchViewAdataper;
private RecyclerView recyclerView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.search_screen_fragment, container, false);
final ProgressDialog progressDialog = new ProgressDialog(view.getContext());
Toolbar mToolbar = (Toolbar) view.findViewById(R.id.toolbar);
mToolbar.setTitleTextColor(Color.WHITE);
mToolbar.setTitle(R.string.title_search);
progressDialog.setMessage(getString(R.string.loading_data));
recyclerView = (RecyclerView) view.findViewById(R.id.search_recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(view.getContext(), LinearLayoutManager.VERTICAL, false));
SearchManager searchManager = new SearchManager(view.getContext());
searchManager.getAllProfessions(new SearchServiceListener() {
@Override
public void onSuccess(List<SearchDataModel> searchDataModels) {
searchViewAdataper = new SearchViewAdataper(getContext(), searchDataModels);
recyclerView.setAdapter(searchViewAdataper);
progressDialog.dismiss();
}
@Override
public void onFail(Throwable t) {
progressDialog.dismiss();
Toast.makeText(getContext(), R.string.communication_server_problem, Toast.LENGTH_LONG).show();
}
});
return view;
}
}
SearchSectionAdapter adapter: Here it manage all cards items and action click Listener from card item to call a new fragment
NOTE: I will put just setOnClickListener implementation. if necessary all implementation let me know and I can update this question.
holder.mSearchItemImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View v) {
ProfessionalManager professionalManager = new ProfessionalManager(v.getContext());
professionalManager.getAllProfessionalByProfessionDescription(singleItem.getDescription(), new ProfessionalServiceListener() {
@Override
public void onSuccess(List<Professional> professionals) {
/*Intent intent = new Intent(v.getContext(), ProfessionalListActivity.class);
v.getContext().startActivity(intent);*/
Fragment fragment = new ProfessionalListFragment();
FragmentTransaction ft = ((FragmentActivity)context)
.getSupportFragmentManager()
.beginTransaction();
ft.replace(R.id.search_recyclerView, fragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.addToBackStack(null);
ft.commit();
}
@Override
public void onFail(Throwable t) {
}
});
}
});
