如果我選擇大圖像，OnActivityResult崩潰

我必須獲取圖庫中圖像的圖像路徑，將其保存爲列表，不幸的是，如果選擇的圖像太大，以下代碼會崩潰應用程序（以及我的警報嘗試catch塊不被查看）。如果我選擇大圖像，OnActivityResult崩潰

private void openImage() { 

     try{ 
      Intent i = new Intent(Intent.ACTION_GET_CONTENT); 
      i.setType("image/*"); 
      startActivityForResult(i, FILE_REQ_CODE); 
      } catch (RuntimeException e) { 
          e.printStackTrace(); 
       Alerts.TooLargeImage(LoadImage.this); 
      } 

    } 

    protected void onActivityResult(int requestCode, int resultCode, 
      Intent intentData) { 
     try{ 
      Uri tmp = intentData.getData(); 
      String path = tmp.toString(); 
      imagePathList.add(path); 
      preview.setImageURI(tmp); 
      FileArchiveManager.saveImagePath(imagePathList); 
      super.onActivityResult(requestCode, resultCode, intentData); 
      } catch (RuntimeException e) { 
          e.printStackTrace(); 
       Alerts.TooLargeImage(LoadImage.this); 
      } 
    }

如何解決這個問題？

從http://developer.android.com/training/displaying-bitmaps/load-bitmap.html：

public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId, 
    int reqWidth, int reqHeight) { 

    // First decode with inJustDecodeBounds=true to check dimensions 
    final BitmapFactory.Options options = new BitmapFactory.Options(); 
    options.inJustDecodeBounds = true; 
    BitmapFactory.decodeResource(res, resId, options); 

    // Calculate inSampleSize 
    options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight); 

    // Decode bitmap with inSampleSize set 
    options.inJustDecodeBounds = false; 
    return BitmapFactory.decodeResource(res, resId, options); 
} 

mImageView.setImageBitmap(decodeSampledBitmapFromResource(getResources(), R.id.myimage, 100, 100));

使用BitmapFactory.decodeResource()和BitmapFactory.Options.inSampleSize將讓你的位圖的下采樣版本加載到RAM（因爲你現實就不需要這麼大的圖像顯示），而不會造成java.lang.OutofMemoryError。

感謝您的回答，但我不知道如何在我的方法 – AndreaF

中使用您的代碼與java.io.EOFException的應用程序崩潰，並沒有顯示圖庫，如果我嘗試使用setImageBitmap（decodeSampledBitmapFromResource（getResources （），R.id.myimage，100，100））;在onActivityResult – AndreaF

你能給我更多關於EOFException的細節嗎？ –
