android.view.inflateException Android

Question

이미지 버튼이있는 자바 클래스와 레이아웃을 하나 만들었습니다. 내용보기를 설정하면 런타임 예외가 발생합니다.

XML 레이아웃 :

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@drawable/letters_bg" > 

    <ImageButton 
     android:id="@+id/imageButton1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentLeft="true" 
     android:layout_marginBottom="49dp" 
     android:src="@drawable/leftsignpost" /> 

</RelativeLayout> 

자바 클래스 코드 :

public class LettersScreenActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     setContentView(R.layout.letters_screen); // error is here 
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 

    } 
} 

그래서 문제는 무엇인가? 왜 런타임 예외가 발생합니까 ??

Answer 1

나는 ...이 코드를 시도했습니다 그것 정말 일 잘 ... 당신이 당신의 드로어 블을 확인하면 확인 했

Answer 2

제공되는 코드에 명백한 문제가 있습니까? 실행해야합니까? 적어도 나를 위해 않습니다 (드로어 블은 물론 내 것입니다).

참조 된 리소스 letters_bg 및 leftsignpost이 있는지 확인하십시오. 이 값은 res/drawable이어야합니다. 프로젝트를 청소하십시오. 더 긴 스택 추적을 제공하십시오.
