下面是$ C $词用于前向和反向

  //向前行驶

 forward_button.setOnTouchListener（新View.OnTouchListener（）{

        @覆盖
        公共布尔onTouch（视图V，MotionEvent事件）{
            如果（（event.getAction（）== MotionEvent.ACTION_DOWN）|（event.getAction（）== MotionEvent.ACTION_MOVE））{
                forward_button.set pressed（真正的）;
                Arduino的=（字节）（Arduino的| 16）;
                写（Arduino的）;
                返回true;

            }否则，如果（event.getAction（）== MotionEvent.ACTION_UP）{
                forward_button.set pressed（假）;
                Arduino的=（字节）（Arduino的＆安培; 236）;
                写（Arduino的）;
                返回true;
            }
            forward_button.set pressed（假）;
            返回false;
        }
    }）;

   //备份

 reverse_button.setOnTouchListener（新View.OnTouchListener（）{

        @覆盖
        公共布尔onTouch（视图V，MotionEvent事件）{
            如果（（event.getAction（）== MotionEvent.ACTION_DOWN）|（event.getAction（）== MotionEvent.ACTION_MOVE））{
                reverse_button.set pressed（真正的）;
                Arduino的=（字节）（Arduino的| 32）;
                写（Arduino的）;
                返回true;

            }否则，如果（event.getAction（）== MotionEvent.ACTION_UP）{
                reverse_button.set pressed（假）;
                Arduino的=（字节）（Arduino的＆安培; 220）;
                写（Arduino的）;
                返回true;
            }
            reverse_button.set pressed（假）;
            返回false;
        }
    }）;

我想用相同的方式用于左和右功能如;

  left_button.setOnTouchListener（新View.OnTouchListener（）{

        @覆盖
        公共布尔onTouch（视图V，MotionEvent事件）{
            如果（（event.getAction（）== MotionEvent.ACTION_DOWN）|（event.getAction（）== MotionEvent.ACTION_MOVE））{
                left_button.set pressed（真正的）;
                Arduino的=（字节）（Arduino的| 8）;
                写（Arduino的）;
                返回true;

            }否则，如果（event.getAction（）== MotionEvent.ACTION_UP）{
                left_button.set pressed（假）;
                Arduino的=（字节）（Arduino的＆安培; 244）;
                写（Arduino的）;
                返回true;
            }
            left_button.set pressed（假）;
            返回false;
        }
    }）;

是做什么的？这种单向

解决方案

  mLButton =（按钮）findViewById（R.id.button_l）;
        mLButton.setOnClickListener（新OnClickListener（）{
            公共无效的onClick（视图v）{
                //发送一条消息使用编辑文本小窗口的内容
                字符串消息=D+左+，+站+ N的;
                的sendMessage（消息）;
            }
        }）;

        }）;
        mRButton =（按钮）findViewById（R.id.button_r）;
        mRButton.setOnClickListener（新OnClickListener（）{
            公共无效的onClick（视图v）{
                //发送一条消息使用编辑文本小窗口的内容
                字符串消息=D+右+，+站+ r  N的;
                的sendMessage（消息）;
            }

下面是一个例子。

Here is the code i use for the forward and reverse

// Drive forward

 forward_button.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if ((event.getAction() == MotionEvent.ACTION_DOWN) | (event.getAction() == MotionEvent.ACTION_MOVE)) {
                forward_button.setPressed(true);
                Arduino = (byte) (Arduino | 16);
                write(Arduino);
                return true;

            }else if (event.getAction() == MotionEvent.ACTION_UP) {
                forward_button.setPressed(false);
                Arduino = (byte) (Arduino & 236);
                write(Arduino);
                return true;
            }
            forward_button.setPressed(false);
            return false;
        }
    });

   // Back up

 reverse_button.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if ((event.getAction() == MotionEvent.ACTION_DOWN) | (event.getAction() == MotionEvent.ACTION_MOVE)) {
                reverse_button.setPressed(true);
                Arduino = (byte) (Arduino | 32);
                write(Arduino);
                return true;

            }else if (event.getAction() == MotionEvent.ACTION_UP) {
                reverse_button.setPressed(false);
                Arduino = (byte) (Arduino & 220);
                write(Arduino);
                return true;
            }
            reverse_button.setPressed(false);
            return false;
        }
    });

I am thinking of using the same way for the left and right function such as;

   left_button.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if ((event.getAction() == MotionEvent.ACTION_DOWN) | (event.getAction() == MotionEvent.ACTION_MOVE)) {
                left_button.setPressed(true);
                Arduino = (byte) (Arduino | 8);
                write(Arduino);
                return true;

            }else if (event.getAction() == MotionEvent.ACTION_UP) {
                left_button.setPressed(false);
                Arduino = (byte) (Arduino & 244);
                write(Arduino);
                return true;
            }
            left_button.setPressed(false);
            return false;
        }
    });

Is this one way of doing it??

解决方案

   mLButton = (Button) findViewById(R.id.button_l);
        mLButton.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                // Send a message using content of the edit text widget
                String message = "D," + left + "," + stop + "n";
                sendMessage(message);
            }
        });

        });
        mRButton = (Button) findViewById(R.id.button_r);
        mRButton.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                // Send a message using content of the edit text widget
                String message = "D," + right + "," + stop + "rn";
                sendMessage(message);
            }

Here is one example.
