Scrollview XML 레이아웃 문제

Question

희망은 간단합니다.

나는 scrollview를 사용하는 레이아웃을 가지고 있습니다. 이것은 이미지와 텍스트 뷰를 그 위에 놓고 그 아래에있는 내 edittext와 함께 scrollview를 가질 때까지 괜찮 았습니다.

순간에 나는 다음과 같은 오류가 받고 있어요 : 나는 행운과 (내가 그 오류가 너무 가리키는 생각) 스크롤 뷰 너비 속성을 변경하는 것을 시도했다

01-22 20:13:32.228: E/AndroidRuntime(275): FATAL EXCEPTION: main

.

내 XML은 다음과 같습니다. 누군가가 내가 잘못인가요? :

를 당신 만있는 ScrollView 한 아이의 레이아웃을 설정할 수 있습니다. 나는 당신이 android:layout_width 속성을 설정하지 않았다는 것을 왜 보여주고 있는지 알지 못하지만, ScrollView에 여러 개의 자식 뷰가 있다는 것이 문제입니다.
