Android : 레이아웃을 부 풀릴 때 InvocationTargetException이있는 StackOverFlowError

Question

첫 번째로, 내 영어를 유감스럽게 생각합니다.

저는 사용자 정의보기가 있습니다. LinearLayout에서 확장하여 ButtonHelp이라고합니다. 내 레이아웃에서보기를 LoadingActivity으로 사용합니다. 내 아래 코드는 다음과 같은 오류와 함께 삼성 갤럭시 Y 등의 QVGA 스크린을 제외한 모든 장치 및 에뮬레이터에서 완벽하게 작동 :

Caused by: java.lang.StackOverflowError 
    at android.util.LongSparseArray.get(LongSparseArray.java:79)

, 나는이 선에 대해 아무 생각이 없다 왜 QVGA 에뮬레이터/장치에서 발생합니까? 참고로

는 :

• 나는 화면 320 × 480 단지에 대한 이미지 자료를 가지고있다.

• ButtonHelp 레이아웃 :

  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content" 
  android:orientation="vertical" > 
  
  <ImageButton 
      android:id="@+id/btnhelp_help" 
      android:layout_width="40dp" 
      android:layout_height="40dp" 
      android:layout_marginLeft="5dp" 
      android:layout_marginRight="5dp" 
      android:layout_marginTop="5dp" 
      android:background="@drawable/loading_button_help" 
      android:src="@drawable/loading_icon_help" /> 
  </LinearLayout> 
  

• ButtonHelp 번호 :

  :

  public class ButtonHelp extends LinearLayout { 
      private ImageButton mHelp; 
  
      public ButtonHelp(Context context, AttributeSet attrs) { 
       super(context, attrs); 
       initLayout(); 
       initControls(); 
      } 
  
      public ButtonHelp(Context context) { 
       super(context); 
       initLayout(); 
       initControls(); 
      } 
  
      private void initLayout() { 
       LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       inflater.inflate(R.layout.btn_help, this); 
      } 
  
      private void initControls() { 
       mHelp = (ImageButton) findViewById(R.id.btnhelp_help); 
      } 
  
      public void setOnClickListener(View.OnClickListener listener) { 
       mHelp.setOnClickListener(listener); 
      } 
  } 
  

• ButtonHelp는 LoadingActivity에 사용

• ButtonHelp을 제거하면 위의 logcat과 마찬가지로 레이아웃을 만들 때 오류가 계속 표시됩니다.

다른 SO 질문을 검색했지만이 경우에는 해결책이나 설명이 없습니다.

감사합니다.

UPDATE : loading_button_help에 대한 질문으로

, 다음과 같습니다 코드 :

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:state_window_focused="false" android:state_enabled="true" 
     android:drawable="@drawable/loading_button_help" /> <!-- Normal --> 

    <item android:state_window_focused="false" android:state_enabled="false" 
     android:drawable="@drawable/loading_button_help" /> <!-- Normal disable --> 

    <item android:state_pressed="true" 
     android:drawable="@drawable/loading_button_help_press" /> <!-- pressed --> 

    <item android:state_focused="true" android:state_enabled="true" 
     android:drawable="@drawable/loading_button_help" /> <!-- selected --> 

    <item android:state_enabled="true" 
     android:drawable="@drawable/loading_button_help" /> <!-- normal --> 

    <item android:state_focused="true" 
     android:drawable="@drawable/loading_button_help" /> <!-- normal disable focused --> 

    <item 
     android:drawable="@drawable/loading_button_help" /> <!-- normal disable --> 
</selector> 

그리고 loading_icon_help 그냥 PNG 이미지입니다.

Answer 1

loading_button_help.xml에서 @ drawable/loading_button_help를 사용합니까? 순환 참조가 있다고 생각합니다. XML 또는 이미지 파일의 이름을 바꾸십시오.
