[FIXED] Android PreferenceScreen password protection

Issue

In my application I would like to have parts of my preferences password protected. There's not really the need to have them "really" secured - it's just that some settings should be only changed "if you know what you do" (it's an enterprise app).

So my preference hierarchy looks something like this:

PreferenceScreen
+-- PreferenceScreen
    +-- SettingA
    +-- SettingB
+-- PreferenceScreen (this one should be password protected)
    +-- SettingC
    +-- SettingD

The problem is, I can't find any way to intercept the clicking of the preferencescreen - I tried to override the onPreferenceTreeClicked method, but that didn't work:

@Override
public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen, Preference preference) {
    if(userHasEnteredCorrectPassword) {
        return super.onPreferenceTreeClick(preferenceScreen, preference);
    } else {
        return false;
    }
}

Obviously because super.onPreferenceTreeClick(...) just start's an fragment in case the preference has set it.

I also tried to set the onClickListener of the preference in the onCreate of the PreferenceFragment - like this:

findPreference("secure_preference_screen").setOnPreferenceClickListener(new OnPreferenceClickListener() {
    @Override
    public boolean onPreferenceClick(Preference preference) {
        if(userHasEnteredCorrectPassword) {
            return true;
        } else {
            return false;
        }
    }
});

But that won't intercept the click as well.

Is there anyone out there who could possibly know how to implement such a feature?

Solution

So just close the fragment if the user don't have the password. Catch it in where you can. It doesn't really matters
