补全发送硬件控制信息到服务器Thread的代码： * 调用mDeviceSelectViewModel的sendRequest方法向服务器发送信息，参数为控制操作标识（mHardwareControlViewModel中的actionType） * 发送信息后延迟1s调用hardwareControlHandler来更新界面（使用mHardwareControlViewModel的startHardwareControlHandler方法）， * runnable为hardwareControlRunnable * 做好异常处理，发生异常时通过sendEmptyMessage调用resetDeviceHandler来提示错误并重置界面状态 Thread hardwareRequestThread =

new Thread(new Runnable() {
@Override
public void run() {
try {
mDeviceSelectViewModel.sendRequest(mHardwareControlViewModel.getActionType());
Thread.sleep(1000);
mHardwareControlViewModel.startHardwareControlHandler(hardwareControlRunnable);
} catch (Exception e) {
resetDeviceHandler.sendEmptyMessage(0);
}
}
});
hardwareRequestThread.start();
