                    editor.putString("yearofbirth", yearofbirth_);
                    editor.putString("gender", gender_);
                    editor.apply();


SharedPreferences sharedPreferences1 = getContext().getApplicationContext().getSharedPreferences("userDataInSharedPref", Context.MODE_PRIVATE);
        String uname = sharedPreferences1.getString("name", "");

        binding.logout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                SharedPreferences.Editor editor = sharedPreferences1.edit();
                editor.clear();
                editor.commit();

//                SharedPreferences sharedPreferences = getActivity().getApplicationContext().getApplicationContext().getSharedPreferences("autoLogin", Context.MODE_PRIVATE);
            }
        });

Check if you are using any singleton class where you might be retrieving the values of these variables using SharedPreferences. The instance of this class need to be set to null too along with above solution.

to clear one string :

sharedPreferences.edit().remove("name").commit();

to clear all strings :

sharedPreferences.edit().clear().apply();

To clear it you need to add this code

public void clear(){
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.clear();
    editor.apply();
}
