在ImageView的不从画廊

显示的画面我试图从我的应用程序库获取图像，并把它的ImageView，但我得到错误“的OutOfMemoryError”在ImageView的不从画廊

代码正从意图galery图像。 ACTION_PICK和onActivityResult（）：

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 

     super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 

     Bitmap bitmap = null; 
     ImageView imageView = iVAddProductDiscountPicture; 

     switch (requestCode) { 
      case GALLERY_REQUEST: 
       if (resultCode == RESULT_OK) { 
        Uri selectedImage = imageReturnedIntent.getData(); 
        try { 
         bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), selectedImage); 
         final ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
         bitmap.compress(Bitmap.CompressFormat.JPEG, 10, stream); 
         Bitmap decoded = BitmapFactory.decodeStream(new ByteArrayInputStream(stream.toByteArray())); 
         //TODO: дописать код сжатия изображения 
         imageView.setImageBitmap(decoded); 

        } catch (IOException e) { 
         e.printStackTrace(); 
        } 
        alertDialog.dismiss(); 

       } 
     } 
    }

'OutOfMemoryError'意味着图像太大，您的设备来处理。加载它已经缩放。 –

@MichaelDodd，文件大小无关紧要，只有解决方法。 –

@Wladimir Rudnicky请将位图压缩大小从10增加到100并尝试使用bitmap.compress（Bitmap.CompressFormat.JPEG，100，stream）; –

在的onCreate（）

imgProfile.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Intent gallary = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
      startActivityForResult(gallary,LOAD_IMG); 
     } 
    });

onCrea以外TE（）

@Override 
    protected void onActivityResult(int requestCode,int resultCode,Intent data){ 
    super.onActivityResult(requestCode,resultCode,data); 

    try{ 
     if(requestCode==LOAD_IMG && resultCode==RESULT_OK && data!=null){ 

      Uri selectedImage = data.getData(); 
      String []filePath = {MediaStore.Images.Media.DATA}; 

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

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

      imgProfile.setImageBitmap(BitmapFactory.decodeFile(imgDecodableString)); 

     }else{ 
      Toast.makeText(this, "Please select image", Toast.LENGTH_LONG).show(); 
     } 
    }catch (Exception e){ 
     Toast.makeText(this, "error", Toast.LENGTH_LONG).show(); 
    } 
}

我试过了。图像视图得到空的图像，但我没有得到错误 - 进展 –

请详细解释**，**如何解决'OutOfMemoryError'。 – CommonsWare

尝试这一点：

public void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (resultCode == RESULT_OK) { 
      if (requestCode == SELECT_PICTURE) { 
      selectedImageUri =data.getData(); 
       Log.d("uri:----",""+selectedImageUri); 
    if (null != selectedImageUri) { 
       imgView.setImageURI(selectedImageUri); 
      } 
     } 
    }
