조각을 RoboGuice 조각으로 변경 하시겠습니까?

Question

내 응용 프로그램에서 RoboGuice를 사용하려고합니다. 내 첫 번째 시도는 간단한 조각을 RoboFragment로 변경하는 것입니다. 하지만 앱을 더 이상 컴파일 할 수 없습니다. 여기에 무슨 문제가있을 수 있습니까? 에서

class MyFragment extends RoboFragment { 

     @InjectView(R.id.progress_bar) private static ProgressBar progressBar; 
    } 

결과 :

E/AndroidRuntime(1237): java.lang.RuntimeException: Unable to start activity 
ComponentInfo{path.to.MyApp}: android.view.InflateException: Binary XML file line #34: 
Error inflating class fragment 
. 

/편집 :

내 문제는 진행 막대 조각 내 나는이 일을 해요 있다는 생각 :

public static void setProgressBar(Activity parent, int visible) { 
    progressBar = (ProgressBar) parent.findViewById(R.id.progress_bar); 
} 

이 힘 아마 RoboGuice 주사와 함께 작동하지 않을까요?

Answer 1

모든 예외를 포함하여 전체 logcat 출력을 게시하는 경우 수정해야 할 오류를 찾아 낼 수 있습니다. xml inflate 라인 34에는 .fragment가 포함되어 있습니다. 단편에서 logcat 출력의 오류가 포함 된 부분을 나타내는 예외가 있어야합니다. 06 : 23.063 : E는/AndroidRuntime는 (676)에 의해 발생 : 는 java.lang.IllegalArgumentException가 : MyActivity @ 412f8b38을 것으로 나타나지 않습니다
