Question

在我的Android客户端应用程序中，我试图通过套接字将虚拟操纵杆坐标从客户端（Android）发送到服务器（Arduino）.Tray在主活动中编写包含套接字's'的线程't' ，以将x，y坐标发送到arduino服务器。当我移动操纵杆时，JoystickView类会给我“ x”和“ y”。这将在用户单击“连接”按钮后完成， 'x'是从0到255，也是'y'，但是为了能够知道arduino端女巫的值是'x'并且女巫是'y'，我在y中添加了255，所以y将是255到510。 / p> 虚拟操纵杆为我提供存储在公共变量“ xxx”和“ yyy”中的“ x”，“ y”坐标。将连接按钮与线程“ t，已创建的I套接字”链接在一起，以将“ x”，“ y”发送到服务器。

**我的问题：我的代码可以与Arduino一起使用吗，我可以在Arduino Side中获得x，y吗？我也不能将线程“ t”放在“ public void onClick（View v）”函数中。这是第二个问题：( **
