android - TextView background not displaying -

i've been working on app, , have problem. trying textview background move above current screen. preview renders correctly, emulator , device both don't show it. here code -

<framelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingleft="0dp" android:paddingright="0dp" android:paddingtop="0dp" android:paddingbottom="0dp" tools:context=".inspection" android:baselinealigned="false"> <linearlayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:baselinealigned="false">     <fragment         android:id="@+id/nativeuser_fragment"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:name="com.aadevs.thetabapp.nativeuserfragment"         android:layout_weight="0.5"         tools:layout="@layout/fragment_nativeuser" />     <fragment         android:id="@+id/otheruser_fragment"         android:name="com.aadevs.thetabapp.otheruserfragment"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:layout_weight="0.5"         tools:layout="@layout/fragment_otheruser" /> </linearlayout> <relativelayout     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_gravity="center"     android:paddingleft="40dp"     android:paddingright="40dp"     android:paddingbottom="60dp"     android:paddingtop="60dp"     android:background="@drawable/debtcircle">     <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="hey there"         android:layout_gravity="center"/> </relativelayout> 

here code drawable debtcircle -

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="ring"> <stroke     android:width="2px"/> <solid android:color="#ffffff"/> 

here different renders (preview, emulator , device)

as can see, preview works fine, emulator , device not working expected. can me?

there problem in drawable.... should use below drawable...

   <?xml version="1.0" encoding="utf-8"?>    <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="oval">    <stroke     android:width="2dp"      android:color="strokecolorhere"/>     <solid android:color="#ffffff"/>   </shape> 

give stroke color if want...just use it...
