We have a custom control which is inherited from EditText. When we are trying to set background color to that component. The bordercolor of the component is disappeared. We could able to reproduce the same issue with EditText also. Here we have attached a sample to replicate the above mentioned issue.
It looks like the border in the default Android EditText widget is actually a background drawable with different states and not a separate component which is why it disappears after changing the background. To have a background and retain the underline border, you'll have to use your own 9-patch image or custom shape as mentioned here. You could also set the BackgroundColor on the Forms Entry control itself and that appears to keep the underline border as well. Hope this helps!
