안드로이드 화면 크기 구하기 라고 쳣을떄
많은 소스들 정보가 나오면
여러가지 방법이 있는데 사용할때마다 계속 튕깁니다.. 오류;;;
그래서 view를 fill로 해놓고
소스에서 getwidtrh를 사용하려고했는데 0을 내뱉는데...
어떻게 해야하죠???
화면 크기를 불러오는게 가장 좋은데 참 왜 오류가
<uses-sdk android:minSdkVersion="10" /> 이거도 제대로 되있는데말이져

View의 크기를 onCreate에서 가져오려고하면 무조건 0입니다.
이유는 화면에 그려지지도않았는데... 크기를 가져오려고 하기때문이죠 이때는 핸들러를 쓰시면됩니다
