안드로이드 비트 맵 편집 된 텍스트의 재활용 오류

Question

2 액티비티가 2 ImageViews으로 표시됩니다. 하나는 정사각형에 맞게 잘리고 두 번째 것은 첫 번째를 기반으로하고 CenterCropped은 흐림이있는 배경 이미지로 채 웁니다. 배경 이미지 흐림 프로세스는 스레드에서 발생합니다. 그 활동을 언급 한 직후 ActivityForResult에 의해 다른 활동 (예 : TextView, 확인 및 취소 버튼)과 같은 간단한 대화 상자를 호출하려고합니다. 작업이 완료되고 모든 것이 양호한 [확인/취소] 버튼을 클릭하면 Edittext을 입력하려고 할 때 문제가 발생하고 Cannot draw recycled bitmap 오류가 발생하여 다른 활동에 있음을 알 수 있습니다 !! 키보드가 뷰를 위로 밀어서 SoftPan에 액티비티를 설정하고 여전히 그 메시지를 받으면서 그것이 일어 났을 것이라고 생각했습니다. 배경을 흐리게 만드는 부분을 제거하면 앱이 정상적으로 작동합니다. 다음은 코드의 일부입니다 :

이 방법 프로세스 JNI에서 이미지를, 그것의 약 3200px X 2400px 배경을 bluring에 대한

private void setImageViewResult() 
{ 
    Bitmap b = BitmapFactory.decodeFile(image.getAbsolutePath()); 
    // store the bitmap in the JNI "world" 
    final JniBitmapHolder bitmapHolder = new JniBitmapHolder(b); 
    // no need for the bitmap on the java "world", since the operations are done on the JNI "world" 
    b.recycle(); 
    // crop a center square from the bitmap, from (0.25,0.25) to (0.75,0.75) of the bitmap. 
    // bitmapHolder.cropBitmap(width/4,height/4,width*3/4,height*3/4); 
    // rotate the bitmap: 
    bitmapHolder.rotateBitmapCw90(); 
    // get the output java bitmap , and free the one on the JNI "world" 
    b = bitmapHolder.getBitmapAndFree(); 
    final int width = b.getWidth(), height = b.getHeight(); 
    // Bitmap b = ExifUtil.rotateBitmap(f.getAbsolutePath(), BitmapFactory.decodeFile(f.getAbsolutePath())); 
    Display display = getWindowManager().getDefaultDisplay(); 
    Point size = new Point(); 
    display.getSize(size); 
    int screenWidth = size.x; 
    int screenHeight = size.y; 
    float boxSize = BOX_SIZE;// dpToPx(338); 
    float boxCenterInScreenHeight = screenHeight/2; 
    float boxCenterInScreenWidth = screenWidth/2; 
    float boxYInScreen = boxCenterInScreenHeight - boxSize/2; 
    float boxXInScreen = boxCenterInScreenWidth - boxSize/2; 
    float boxHeightRatio = boxSize/screenHeight; 
    float boxWidthRatio = boxSize/screenWidth; 
    float yRatio = boxYInScreen/screenHeight; 
    float xRatio = boxXInScreen/screenWidth; 
    float CropFromY = b.getHeight() * yRatio; 
    float CropFromX = b.getWidth() * xRatio; 
    // float HeightAndWidthToCrop = b.getHeight() * 
    // boxHeightRatio; 
    float HeightAndWidthToCrop = b.getWidth() * boxWidthRatio; 
    bitmapHolder.storeBitmap(b); 
    b.recycle(); 
    bitmapHolder.cropBitmap((int) CropFromX, (int) CropFromY, (int) HeightAndWidthToCrop + (int) CropFromX, (int) HeightAndWidthToCrop + (int) CropFromY); 
    bmp = bitmapHolder.getBitmapAndFree(); 
    ivResult.setImageBitmap(bmp); 
    setBackgroundBlur(); 
} 

첨부 :을 (가장 고귀한 RES AT 유지해야) :

private void setBackgroundBlur() 
{ 
    Config.getThreadPool().submit(new Runnable() 
    { 
     @Override 
     public void run() 
     { 
      // bgFile = StorageUtils.newTempFile("jpg"); 
      try 
      { 
       // WebExecutor.executeSync(new DownloadImage(item.getImageCoverUrl(), bgFile)); 
       Bitmap bmp2 = ImageUtils.createCenterCrop(bmp, new DimensionsRect((int) (Config.getScreenDimens().getWidth()/2f), 
                        (int) (Config.getScreenDimens().getHeight()/2f))); 
       bmp2 = ImageUtils.setGpuImageFilter(bmp2, new GPUImageSaturationFilter(1)); 
       Canvas c = new Canvas(bmp2); 
       c.drawColor(0x77000000); 
       bmp2 = ImageUtils.setGpuImageFilter(bmp2, new GPUImageBoxBlurFilter(1f)); 
       System.gc(); 
       bgBitmap = bmp2; 
       handler.post(new Runnable() 
       { 
        @Override 
        public void run() 
        { 
         android.util.Log.i("SEB BACKGROUND BLUR", "in method"); 
         Drawable d = new BitmapDrawable(bgBitmap); 
         // ivBackground.setImageBitmap(bgBitmap); 
         ((RelativeLayout) findViewById(R.id.toot)).setBackground(d); 
         ViewPropertyAnimator.animate(ivBackground).alpha(1).setDuration(500).start(); 
        } 
       }); 
      } catch (Exception e) 
      { 
       e.printStackTrace(); 
      } 
     } 
    }); 
} 

에서 OnCreate는 SetImageViewResult를 호출하고, 두 번째 활동을 시작합니다

@Override 
protected void onCreate(final Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_rename_scan); 
    setSoftPan(); 
    final EditText etName = (EditText) findViewById(R.popScan.name); 
    final Button ok = (Button) findViewById(R.popScan.ok); 
    final Button cancel = (Button) findViewById(R.popScan.cancel); 
    ok.setOnClickListener(new OnClickListener() 
    { 
     @Override 
     public void onClick(final View v) 
     {} 
    }); 
    cancel.setOnClickListener(new OnClickListener() 
    { 
     @Override 
     public void onClick(final View v) 
     { 
      finish(); 
     } 
    }); 
} 

을

setBackgroundBlur 메서드의 내부에서 로그를 열어 키보드가 열린 후에 두 번째 호출되는지 확인하려고했지만 시도하지 않았습니다.

로그 캣 : 그것은 사용 된 메모리이기 때문에 재활용 된 비트 맵

b.recycle(); 

// get the output java bitmap , and free the one on the JNI "world" 
b = bitmapHolder.getBitmapAndFree(); 

그렇지 수 재 할당 값이 예외를 일으키는 코드 부분

Answer 1

인 해방. 당신은 그것을 암호 해독해야합니다. 귀하의 케이스에서 다른 변수를 사용하면 잘 작동합니다.
