在Android监听事件上拖动地图

MapView mapView = findViewById(R.id.mapView);
mapView.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        // 处理触摸事件
        return true;
    }
});

mapView.setOnTouchListener(new View.OnTouchListener() {
    private float lastX, lastY;

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                // 记录按下时的坐标
                lastX = event.getX();
                lastY = event.getY();
                break;
            case MotionEvent.ACTION_MOVE:
                // 计算移动的距离
                float dx = event.getX() - lastX;
                float dy = event.getY() - lastY;
                // 更新地图的位置
                mapView.moveBy(dx, dy);
                // 更新上一次的坐标
                lastX = event.getX();
                lastY = event.getY();
                break;
            case MotionEvent.ACTION_UP:
                // 处理抬起事件
                break;
        }
        return true;
    }
});
