Answer 1

You won't be able to. It was added to in API Level 17 which is 4.2 so the older versions do not support it.

so r u suggesting me to change the order of the elements in the xml ? – Ratal

Probably the best way you create a layout file for specific android API levels. e.g. layout-v17 so that the new APIs use the RTL layout, then create a layout for older verions that have the XML in the way round you need – Vibraculum

Answer 2

Just use ViewCompat using android.support.v4.view to do it.

ViewCompat.setLayoutDirection(findViewById(R.id.my_view), ViewCompat.LAYOUT_DIRECTION_RTL);

Magic!! Great solution! – Nurse

@ArefBahreini This method work on api 17 and above. Check inside of this method - if (VERSION.SDK_INT >= 17) { view.setLayoutDirection(layoutDirection); } – Acrolein

Answer 3

you can change your application language and solve this problem :

String languageToLoad  = "en";
Locale locale = new Locale(languageToLoad);
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config,
getBaseContext().getResources().getDisplayMetrics());
