Why would Eclipse tell me there is no attribute “margin” for a LinearLayout?

Question

I\'m getting an error when I try and build my android project:

No resource identifier found for attribute \'margin\' in package \'android\'

Answer 1

The correct attribute name for declaring a 5p margin in every direction is:

android:layout_margin="5dp"

Note the layout_ prefix. You'll want to remove the line that says android:margin="5dp", which is what makes Eclipse complain.

The full set of valid margin attributes includes:

• layout_margin
• layout_marginBottom
• layout_marginEnd
• layout_marginLeft
• layout_marginRight
• layout_marginStart
• layout_marginTop
