Hello, can anyone tell me how to put the black border with contents inside as shown in the diagram below, Tried several times by adding a border but I'm not getting this desired result. Thanks!

What is your layout XML for this screen, and what results are you getting. If possible, include a screenshot.

I've been using a relative layout and inside it a gridview.. part of my codes is as follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
tools:context="com.example.noush01.mauricraft.MainAct">

<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="EXIT"
android:id="@+id/bExit"
android:layout_marginTop="10dp"
android:layout_alignParentTop="true"
android:background="#fb2020"
android:minHeight="40dp"
android:minWidth="80dp"
android:textAlignment="center"
android:textColor="#ffffff"
android:textSize="20sp"
android:layout_alignEnd="@+id/gridView" />


<GridView

android:layout_width="fill_parent"
android:layout_height="380dp"
android:columnWidth="90dp"
android:gravity="center"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:verticalSpacing="10dp"
android:background="#80aaa7a7"
android:id="@+id/gridView"
android:layout_marginTop="15dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginBottom="5dp"
android:layout_below="@+id/bExit" />

<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Register As Customer"
android:id="@+id/button"
android:layout_below="@+id/gridView"
android:background="#1579fb"
android:textAlignment="center"
android:textColor="#ffffff"
android:textSize="18sp"
android:minHeight="50dp"
android:nestedScrollingEnabled="false"
android:minWidth="200dp"
android:layout_toStartOf="@+id/bExit" /> .............................................................

Im getting as default values inside the gridview as shown below. I don't know how to have them removed also.
