36 Layout FrameLayout 단순히비어있는공간 모든객체들이화면의왼쪽위를기준으로그려짐 프로그래머가직접그리고싶은객체의기준점설정불가 LinearLayout 모든하위구성요소를수직또는수평형태중하나로정렬하여그리는방식 하위구성요소들간의 margin 과정렬방식 (gravity) 지정가능 구성요소별가중치 (android:layout_weight) 지정가능 화면에남는공간을어떻게활용할지결정 176

37 Layout 가중치미적용 177

38 Layout 가중치적용 178

39 Layout TableLayout 테이블의행과열을기준으로하위구성요소들배치 TableLayout 은행을정의하는 TableRow 객체로구성되고, 각행은 0 개이상의셀들로구성 각셀은0개이상의 View 오브젝트로표현되므로셀은비어있는상태가될수있음 열들은비어있는공간을최대로차지하여그릴수도있고, 화면에맞게줄일수도있으며, 보이지않게할수도있다 179
