This solution will only add the border, the body of the LinearLayout will be transparent.
First, Create this border drawable in the drawable folder, border.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android= "http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke android:width="2dp" android:color="#ec0606"/>
<corners android:radius="10dp"/>
</shape>
Then, in your LinearLayout View, add the border.xml as the background like this
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/border">
