EditTextPreference - only numeric value inputType - isn't working

Answer 1

The Customize your settings section in the developer guide for settings recommends that you set the input type programmatically by using an OnBindEditTextListener as follows:

public class SettingsFragment extends PreferenceFragmentCompat {
    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.settings_screen, rootKey);

        EditTextPreference weeklyGoalPref = findPreference("weekly_goal");
        if (weeklyGoalPref != null) {
            weeklyGoalPref.setOnBindEditTextListener(new EditTextPreference.OnBindEditTextListener() {
                @Override
                public void onBindEditText(@NonNull EditText editText) {
                    editText.setInputType(InputType.TYPE_CLASS_NUMBER);
                }
            });
        }
    }
}

I tried defining the input type as "number" in xml and still got the normal keyboard with letters. This approach worked for me.
