Android below 4.2 how to set layoutDirection to be RTL

Question

trying to set the layout elements to be RTL ordered

in 4.2 and above the line: layoutDirection=\"rtl\" and in the manifest: android:supportsRtl=\"true

Answer 1

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

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

Answer 2

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.

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());
