Android触控板

Question

我正在尝试在android中做触摸板，我有问题。 当我按下鼠标按钮时，我的手指无法移动到屏幕上。

鼠标监听器：

mouse1.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    client.send("B:bPressed1");
                    Log.d("Touchpad", "Mouse1 pressed");
                } else if (event.getAction() == MotionEvent.ACTION_UP) {
                    client.send("B:bRelease1");
                    Log.d("Touchpad", "Mouse1 released");
                }
                return false;
            }
        });

覆盖onTouchEvent以获取鼠标位置：

@Override
    public boolean onTouchEvent(MotionEvent e) {
        this.gDetector.onTouchEvent(e);
        float x = e.getX();
        float y = e.getY();

        switch (e.getAction()) {
        case MotionEvent.ACTION_MOVE:
            int dx = (int) (x - mPreviousX);
            int dy = (int) (y - mPreviousY);
            Log.i("Touchpad", dx + "/" + dy);
            client.send("M:" + dx + "/" + dy);

        }
        mPreviousX = x;
        mPreviousY = y;
        return super.onTouchEvent(e);
    }
