I have set default language as Arabic (ar) and it works as expected on my Alcatel device (version 6 Marshmallow) But when I run this app on Samsung device (version 4.1.2 JellyBean) the toolbars(top & bottom) do not show as RTL layout elements. Check out the images of both below.
Alcatel View working well
.
And Samsung View not working as expected
You can see top toolbar & bottom toolbar's elements, not in the same sequence on both devices. I have two drawer elements attached to the top toolbar(left having Category Info Lists with Gravity Start & right having User account related Info List with Gravity End). So they are not showing well too on Samsung.
The last thing for now is in the screen area I have a vertical recyclerview that shows different layout types according to the data available. The Position of these Layouts is also not correct on Samsung.
Note: the recyclerview part does not behave because of language change and it is also different when I run the app in English.
Edit: my adapter Class where I'm preparing data and setting nested recyclerview also.
