從圖庫（SD卡）中挑選圖片以用於我的應用... java.lang.OutOfMemoryError：位圖大小超過虛擬機預算

我在android上選取應用程序中的圖像，我不知道爲什麼，有時我得到了一個例外，我認爲它總是選擇一個超過400或500 kb的圖像，但我不確定。爲什麼？因爲當我選擇100 kb的小圖像時，我沒有得到異常，並且當我得到高KB或MB圖像時，它會與java.lang.OutOfMemoryError: bitmap size exceeds VM budget一起崩潰。 但非常重要：它在模擬器上崩潰，但也在我的手機上崩潰，不是模擬器的故障。從圖庫（SD卡）中挑選圖片以用於我的應用... java.lang.OutOfMemoryError：位圖大小超過虛擬機預算

這是我的代碼：

changeImageButton.setOnClickListener(new OnClickListener() { 
      public void onClick(View v) { 
       Intent i = new Intent(Intent.ACTION_PICK, 
         android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI); 
       startActivityForResult(i, ACTIVITY_SELECT_IMAGE); 
      } 
     }); 



protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 
     super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 

     switch(requestCode) { 
     case 1: 
     { 
      setResult(1); 
      finish();  
     } 
     case ACTIVITY_SELECT_IMAGE: 
      if(resultCode == RESULT_OK){ 
       Uri selectedImage = imageReturnedIntent.getData(); 
       String[] filePathColumn = {MediaStore.Images.Media.DATA}; 

       Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null); 
       cursor.moveToFirst(); 

       int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
       String filePath = cursor.getString(columnIndex); 
       cursor.close(); 

       selectedPhoto = BitmapFactory.decodeFile(filePath); 
       //profileImage.setImageBitmap(selectedPhoto); 
       profileImage.setImageBitmap(Bitmap.createScaledBitmap(selectedPhoto, 80, 80, false)); 
      } 
     } 
    }

profileImage是我佈局的ImageView的。我用縮放butmap的圖像resice到80×80

請給我一些幫助，這個例外，我需要去解決它

這是個例外：

我面臨同樣的問題，這是什麼解決方案@ AndroidUser99 – Crishnan 2014-02-17 12:05:28

Bitmap.createScaledBitmap方法只要我研究過內存消耗高點併產生錯誤，但我並不完全確定它。無論如何，這是JAVA API，你不能更深入。

你可以做下：

//create a Drawable with your image as parameter 
BitmapDrawable d= new BitmapDrawable(youBitmap); 
//define bounds for your drawable  
int left =0; 
int top = 0; 
int right=80; 
int bottom=80; 

Rect r = new Rect(left,top,right,bottom); 
//set the new bounds to your drawable  
d.setBounds(r); 
//set the drawable as view of your image view 
profileImage.setImageDrawable(d);

我還沒有測試此代碼，但它應該工作。

不，它仍然崩潰，同樣的例外：S – NullPointerException 2011-01-31 13:55:07
