Using SharedPreference to save user details


I understand that the best way to save values is to use SharedPreferences e.g.

SharedPreferences Savesettings = getSharedPreferences("settingFile", MODE_PRIVATE);
        SharedPreferences.Editor example = Savesettings.edit();
        example.putString("Name", name)
                .putInt("Age", age)
                .putInt("Score", score)

But what if I want my program to remember a button being disabled or enabled after the user closes and opens the program? i have tried a RegisterOnChangePreferanceListener however i have no luck e.g.

SharedPreferences Preferences= PreferenceManager.getDefaultSharedPreferences(this);
        SharedPreferences.OnSharedPreferenceChangeListener Example =
                new SharedPreferences.OnSharedPreferenceChangeListener() {
                    public void onSharedPreferenceChanged(SharedPreferences preferance, String key) {

                        Name = name;//only an example not the main focus
                        Age = age;
                        Score = score;
                        enableBTN = false; //disables button
                        Name.setEnabled(false); //disables the edit text from further editing

Is there a way to do this, both methods do not seem to be working for me.

    You need to save it from within the button's OnClickListener. That way, everytime the button is clicked, you are guaranteed that the button's state is saved. button is a reference to a Button view object

    public class MainActivity extends Activity {
        protected void onCreate(Bundle bundle) {
            Button button = (Button)findViewById("this_button_view_id");
            EditText editText = (EditText)findViewById("this_edit_text_id");
            SharedPreferences Savesettings = getSharedPreferences("settingFile", MODE_PRIVATE);
            // If the Savesettings shared preferences above contains the "isButtonDisabled" key
            // It means the user clicked and disabled the button before
            // So we use that state instead
            // If it does does not contain that key
            // We set it to true so that the button is not disabled
            // Same for the edit text
            button.setEnabled(Savesettings.contains("isButtonDisabled") ? Savesettings.getBoolean("isButtonDisabled") : true);
            editText.setEnabled(Savesettings.contains("isEditTextDisabled") ? Savesettings.getBoolean("isEditTextDisabled") : true);
            button.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    // disable the edit text
                    // disable the button
                    SharedPreferences.Editor example = Savesettings.edit();
                    // Save the button state to the shared preferences retrieved above
                    example.putBoolean("isButtonDisabled", true);
                    // Save the edit text state to the shared preferences retrieved above
                    example.putBoolean("isEditTextDisabled", true);
