这是我用于拖动当前屏幕的代码。

int screenWidth = getActivity().getWindowManager().getDefaultDisplay().getWidth();
int screenHeight = getActivity().getWindowManager().getDefaultDisplay().getHeight();
int fromX, toX, fromY, toY = 0;
fromX = screenWidth/2;
toX = screenWidth/2;
fromY = (screenHeight/2) + (screenHeight/3);
toY = (screenHeight/2) - (screenHeight/3);
int scroll_time = 10000;             
solo.sleep(5000);
    // Drag UP  
solo.drag(fromX, toX, fromY, toY, 40);
Log.d(TAG, "Drag 1");
    // here default origin (x,y = 0,0) is left upper corner

这里滚动工作但很慢。

那么对于快速滚动需要对这段代码进行哪些更改？

我遇到了同样的问题，您需要做的是调整以下代码行，

solo.drag(fromX, toX, fromY, toY, 40); //Change 40 to 10

这将提高您的滚动速度，步数越低，滚动越快！

            return true;
        }

   }
 }

看到这个它是使用完整的 Android 在屏幕上拖放图像吗？
