Create a class instance

public class AddFragment extends Fragment { private DataBaseHelper myDb; private Button writeButton, deleteButton; private EditText namePassEdit, emailEditText, pasEditText, informationEditText; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.new_add_fragment, null); initializeViews(rootView); return rootView; } private void initializeViews(View rootView){ namePassEdit = rootView.findViewById(R.id.nameEditText); emailEditText = rootView.findViewById(R.id.emailEditText); pasEditText = rootView.findViewById(R.id.passwodEditText); informationEditText = rootView.findViewById(R.id.infoEditText); writeButton = rootView.findViewById(R.id.writeButton); /*deleteButton = rootView.findViewById(R.id.delButton); deleteButton.setVisibility(rootView.GONE);*/ writeButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { PassClass passClass = new PassClass(); passClass.setName(namePassEdit.getText().toString()); passClass.setEmail(emailEditText.getText().toString()); passClass.setPassword(pasEditText.getText().toString()); passClass.setInfo(informationEditText.getText().toString()); if (new DBAdapter(getActivity()).savePass(passClass)){ Toast.makeText(getActivity(), "SUCCESS", Toast.LENGTH_SHORT).show(); } else { Toast.makeText(getActivity(), "Not Saved", Toast.LENGTH_SHORT).show(); } } }); } public void writeToSql(){ } @Override public void onDestroyView() { super.onDestroyView(); }}

There is an identical fragment that is created without problems, fragments are called via a common function.

 private void setFragment(Fragment fragment) { FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); fragmentTransaction.replace(R.id.main_frame, fragment); fragmentTransaction.commit(); }

I looked in debug mode, I saw the following. I think the problem is this. What it is and how to get rid of it debug mode

    See what value you are passing to the variable.

     Fragment fragment

    in the method

     private void setFragment(Fragment fragment){}

    and compare with the variable that you pass when you call setFragment (), where this method works correctly. In general, you should transmit a new instance instance -

     setFragment(new YourFragmentName());

    Ps Complete the FragmentTransaction like this:

     FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.replace(R.id.main_frame, fragment); ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE); ft.addToBackStack(null); ft.commit();
