Hello ozkaro,​

Welcome to our Microsoft Q&A platform!

To change the background color programatically, try to get the shape drawable and then use SetTint to change the color value.

Check the code:

   //layout.xaml  
   <TextView  
       android:id="@+id/text"  
       android:background="@drawable/custom_shape"  
       android:text="testing..."  
       android:layout_width="match_parent"  
       android:layout_height="wrap_content"/>  
     
   //change the background  
   var text = FindViewById<TextView>(Resource.Id.text);  
   Drawable background = text.Background;  
   background.SetTint(Resource.Color.colorAccent);
