Is it possible to preview the RTL view for layouts in XML Preview on Android Studio?

To force right-to-left layouts on your Android device you need to open Settings, and access the Developer options menu (if developer options aren't enabled, here's how to do it). Once you've accessed the menu, scroll down to find the “Force RTL layout direction” tab. Tap on it to activate the option, and you're done.
A layout direction can be left-to-right (LTR) or right-to-left (RTL). It can also be inherited (from a parent) or deduced from the default language script of a locale.
Just go to Android Studio > Refactor > Add RTL support where possible… I would recommend you checking your app once after applying this change as you might not want all your Layouts/Views to be RTL. If you want to force any layout to LTR then just add android:layoutDirection="ltr" to that view.
On devices running Android 4.4 (API level 19) or higher, you can enable Force RTL layout direction in the on-device developer options. This setting allows you to see text that uses LTR scripts, such as English text, in RTL mode.
For preview you can set your xml parent view with android:layoutDirection="rtl"
For example,
item.xml
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="2dp"
card_view:cardCornerRadius="2dp"
card_view:cardElevation="2dp"
card_view:cardUseCompatPadding="true"
android:layoutDirection="rtl"
>
//design
</android.support.v7.widget.CardView>
android:layoutDirection="rtl"
Output :
