How can I create a border around an Android LinearLayout?

Question

I have one big layout, and one smaller layout inside of it.

How do I create a line border around the small layout?

Answer 1

I'll add Android docs link to other answers.

https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape

It describes all attributes of the Shape Drawable and stroke among them to set the border.

Example:

Red border with transparent background.
