How to right align PreferencesActivity in android?

Question

I have PreferencesActivity which I need it to be right aligned because I want to use Arabic language, I tried to use android:layout_gravity="right" for PreferenceScreen but it didn't work.

This is my XML:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" android:layout_gravity="right">
        <PreferenceCategory android:title="General Settings">
                <CheckBoxPreference
                        android:title="Full Screen"
                        android:defaultValue="false"
                        android:summary="Always view as Full Screen"
                        android:key="fullScreenPref" />
        <Preference
                android:title="Report Bugs"
                android:summary="Notify us for any Bugs or Errors"
                android:key="bugs"/>
        <Preference
                android:title="About"
                android:summary="Version 1.0.0"
                android:key="about"/>
        </PreferenceCategory>
</PreferenceScreen>

This is how I use the XML inside PreferencesActivity:

addPreferencesFromResource(R.layout.preferences);

After spending some time searching about our shared question, I found nothing useful. obviosly android api doesn't support RTL prefefrences. it means no support for persian/hebrew/arabic languages. But afterall I tried to find some way to right align an editText. I drived EditTextPreference class and implemented onCreateView method again. here is my code:

/**
 * Created by omid on 1/12/14.
 */
public class RtlTextPreference extends EditTextPreference {


    public RtlTextPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected View onCreateView(ViewGroup parent) {
        View view = super.onCreateView(parent);

        RelativeLayout layout = (RelativeLayout) ((LinearLayout) view).getChildAt(1);
        layout.setGravity(Gravity.RIGHT);
        return view;
    }
}

the rest of the preferences in the standard android api should be the same(btw I haven't tried yet). maybe someday we should fully implement rtl support in android preferences and host it on github. Hope this code snippet helps you.
