Implement custom drawable file for textview

If we want a custom background for a button we need to have a drawable file which defines the shape,size and color of the button layout and this will be the drawable which will set as background of the button in the layout file. So in this step you need  to have an xml file under your res/drawable/

rounded_corner_button.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape
            android:shape="rectangle">

            <solid
                android:color="@color/colorPrimary"/>

            <stroke
                android:color="@color/colorAccent"
                android:width="2dp" />

            <corners
                android:radius="15dp" />
        </shape>
    </item>
</selector>

Create the Button in layout file with custom background

Once the drawable file is created you need to create the button in your layout file and simply use the above drawable file in your textview as in the following code

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Rounded Button"
    android:background="@drawable/rounded_corner_button"
    android:textColor="@color/white"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:padding="15dp"
    />

Add the required colors
