안드로이드 스튜디오 Linear Layout

종류는 2가지이다.

android:orientation=“vertical” // 세로

android:orientation=“horizontal” // 가로

android:layout_width/height:"match_parent/wrap_content”

match_parent- 내용과 상관없이 화면을 꽉 채움

wrap_content- 내용이 들어있는 만큼만 화면을 차지한다

Android:textColor=“#fc0000”

Android:background= “#68f1fd"

일반 레이아웃과 달라진 점 ?
