I have one big layout, and one smaller layout inside of it.
How do I create a line border around the small layout?
Sure. You can add a border to any layout you want. Basically, you need to create a custom drawable and add it as a background to your layout. example:
Create a file called customborder.xml
in your drawable folder:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<corners android:radius="20dp"/>
<padding android:left="10dp" android:right="10dp" android:top="10dp" android:bottom="10dp"/>
<stroke android:width="1dp" android:color="#CCCCCC"/>
</shape>
Now apply it as a background to your smaller layout:
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/customborder">
That should do the trick.
