Answer 1

Change all of your app's left/right layout properties to new start/end equivalents.

Simply example, use in android:gravity.

Don't forget to declare in your app Manifest that your app supports RTL mirroring: add android:supportsRtl="true" to the element in your Manifest file.

Answer 2

setLocale("en");//set English

setLocale("ar");//set Arabic

public void setLocale(String lang) {
        Locale locale = new Locale(lang);
        Locale.setDefault(locale);
        Configuration config = new Configuration();
        config.locale = locale;
        getBaseContext().getResources().updateConfiguration(config,
                getBaseContext().getResources().getDisplayMetrics());
    }

will automatic RTL after set locale as English and LTR set locale as Arabic. //Don't forget to restart your app. after set locale

No need to change gravity

Answer 3

To make your TextView work for RTL, you should add layout properties of RTL.

Use android:layout_marginStart in place of android:layout_marginLeft and android:layout_marginEnd in place of android:layout_marginRight

For left-to-right flow, start=left, end=right.

For right-to-left flow, start=right, end=left.

This RTL support was added in API Level 17, as part of Android 4.2's support for RTL layouts. This will help you https://developer.android.com/about/versions/android-4.2.html#RTL
