通过蓝牙将按钮值发送到连接的设备

Question

您好，我们在uni开设了一个项目，我们在其中开发了井字游戏。与原始版本的区别在于它是通过蓝牙连接的多人游戏，主机可以选择一组要使用的游戏。我已经可以连接两个设备，并且已经设置了游戏代码。但是，我似乎无法将一组游戏的按钮的值发送到其他设备。所选游戏集只能在主机设备上加载。谁能帮帮我吗。非常感谢

GameLobby.java

      btnChoice1 = (Button) MyDialog.findViewById(R.id.btnChoice1);
            btChoice1.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    PieceChoice = 1;
                    Toast.makeText(GameLobby.this, "Game piece chosen. Waiting for connection", Toast.LENGTH_LONG).show();
                    MyDialog.dismiss();
                }
            });

GameLobby.java上的处理程序

 private final Handler mHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        switch (msg.what) 
        {
            case MESSAGE_DEVICE_NAME:
        mChoice = msg.getData().getInt(FCHOICE);
        switch (mChoice)
                    {
                        case 1:
                            loadGameBoard1();
                            break;
                        case 2:
                            loadGameBoard2();
                            break;
                        case 3:
                            loadGameBoard3();
                            break;

                    }

BluetoothService.java

        Message msg = mHandler.obtainMessage(GameLobby.MESSAGE_DEVICE_NAME);
        Bundle bundle = new Bundle();
        int pieceChoice = GameLobby.PieceChoice;
        bundle.putInt(GameLobby.FCHOICE, pieceChoice);
        msg.setData(bundle);
        mHandler.sendMessage(msg);
