我收到错误：目标不能为空毕加索

public void getListFromDb(){
    Cursor res = myDb.ViewAll();
    startManagingCursor(res);


    //Map cursor from db to viewFields
    String[] fromFieldNames = new String[]{DatabaseHelper.COL_2, DatabaseHelper.COL_3, DatabaseHelper.COL_4, DatabaseHelper.COL_5};
    int[] toViewIDS = new int[]{R.id.viewName, R.id.viewAddress, R.id.viewPostcode, R.id.viewType};

    //Create SimpleCursorAdaptor with null cursor
    SimpleCursorAdapter myCursorAdaptor = new SimpleCursorAdapter(this, R.layout.item_layout, null, fromFieldNames, toViewIDS, 0);
    // Set adaptor for listView
    myList.setAdapter(myCursorAdaptor);

            .resize(600, 200) // resizes the image to these dimensions (in pixel). does not respect aspect ratio
            .into(img);




    new AsyncTask<SimpleCursorAdapter, Void, Cursor>() {

            this.mSimpleCursorAdapter.changeCursor(cursor);
        }
    }.execute(myCursorAdaptor);




}

                String message = "ID: " + idDB;
                //Toast.makeText(ViewActivity.this, message, Toast.LENGTH_LONG).show();
                String hello = Long.toString(idDB);

                Intent intent = new Intent(ViewActivity.this, ImageFullViewActivity.class);
                intent.putExtra("ImgID", hello);
                startActivity(intent);
            }
        }

    });

}

如何解决此问题。 此外，图像的网址只是暂时的，因为我正在使用它进行测试。我能否在.load（）？

中插入图像的真实路径
