floatingsearchview RTL Layout

Estoy intentando usar floatingsearchview en mi aplicación. Mi aplicación tiene layout RTL y cuando uso floatingsearchview no coincide con el layout RTL. ¿Cómo puedo arreglarlo?

Aquí está mi código xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/parent_view" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" tools:context=".MainActivity"> <android.support.design.widget.AppBarLayout android:id="@+id/appbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> <com.arlib.floatingsearchview.FloatingSearchView android:id="@+id/floating_search_view" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:layoutDirection="rtl" app:floatingSearch_close_search_on_keyboard_dismiss="false" app:floatingSearch_dimBackground="false" app:floatingSearch_dismissOnOutsideTouch="true" app:floatingSearch_leftActionMode="showHamburger" app:floatingSearch_menu="@menu/menu_search_view" app:floatingSearch_searchBarMarginLeft="@dimen/search_view_inset" app:floatingSearch_searchBarMarginRight="@dimen/search_view_inset" app:floatingSearch_searchBarMarginTop="@dimen/search_view_inset" app:floatingSearch_searchHint="@string/search_hint" app:floatingSearch_showSearchKey="true" app:floatingSearch_suggestionsListAnimDuration="250" /> </android.support.design.widget.AppBarLayout>
