Child background attribute overrides the parent rounded corner of the background

Question

I created a navigation bar using a LinearLayout containing a Clickable TextView for containing a LinearLayout. I set the XML form of the background to create rounded corners, the problem is that when the user clicks on one of the tabs that I set to the back color of the tab, the rounded corners are overwritten, the reason I set the rounded corners in the container, and not in tabs, is that the right-left / left-right languages.

Before clicking

After pressing
