Question

我有几页(文本的栏目)的绕过,希望能够在各栏之间横向发展,以回应计票。我可以用滚动(To)来做这一罚款,但这是相当突然的,我确实希望能够从一页顺利过渡到下一页。

The problem as I see it: you can t attach a Scroller to a WebView, and shouldn t nest a WebView in a ScrollView.

是否有任何良好想法在网上通话中实施平稳或不断的横向滚动?

加入: 我试图在我使用未经证实的假肢来计算距离的地方执行一个叫.的想法。

    // vx and vy are from the onfling event of the gesture detector 
    scroller.fling(page*x, 0, vx, vy, page*(x + 1), page*(x + 1), 0, 0);

    while(scroller.computeScrollOffset()){
        webview.scrollTo(scroller.getCurrX(), 0);
        webview.invalidate();
    }

......但是,虽然 lo似乎太慢,无法抓住er者的流动,或者说是这样,因为行为似乎像 s(滚动)方法一样(这种观点 jump到滚动末)。

Answer 1

您不能附在网上浏览器上,但你也可以利用这种姿态。

The gesture detects the fling using this method

onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)

Give the velocityX, velocityY to the scoller method along with other parameters

fling(int startX, int startY, int velocityX, int velocityY, int minX, int maxX, int minY, int maxY)

• 寻找CurrX(CurrY())职位,扫描计算值。

Extend the webview and override the methods onTouchEvent(MotionEvent ev), dispatchTouchEvent(MotionEvent ev) to return false so that by default the touch events are not consumed by the webview itself. Now implement the gestureListener and override the onfling method mentioned above. pass the velocity and other parameters to the scroller. Start a loop to scan the computeScrollOffset() value to find the getCurrX() and getCurrY() and invalidate the view each time. Pass this value to scroll the webview as needed.

如果需要的话,请让我知道。
