在android蜂窝webview/webkit中实现水平/垂直手指滑动滚动？

webView.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        // 手指触摸事件
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            // 记录手指初始位置
            fingerStartX = event.getX();
            fingerStartY = event.getY();
        } else if (event.getAction() == MotionEvent.ACTION_MOVE) {
            // 计算手指移动的距离
            float deltaX = event.getX() - fingerStartX;
            float deltaY = event.getY() - fingerStartY;

            // 判断手指滑动的方向
            if (Math.abs(deltaX) > Math.abs(deltaY)) {
                // 手指向下滚动
                if (deltaX > 0) {
                    // 垂直滚动
                    if (webView.canScrollVertically(SCROLL_VERTICAL)) {
                        webView.scrollTo(0, fingerStartY - deltaY);
                    }
                } else {
                    // 水平滚动
                    if (webView.canScrollHorizontally(SCROLL_HORIZONTAL)) {
                        webView.scrollTo(fingerStartX - deltaX, 0);
                    }
                }
            } else {
                // 手指向左滚动
                if (deltaY > 0) {
                    // 垂直滚动
                    if (webView.canScrollVertically(SCROLL_VERTICAL)) {
                        webView.scrollTo(0, fingerStartY - deltaY);
                    }
                } else {
                    // 水平滚动
                    if (webView.canScrollHorizontally(SCROLL_HORIZONTAL)) {
                        webView.scrollTo(fingerStartX - deltaX, 0);
                    }
                }
            }
        }
        return false;
    }
});
