Web视图内容的Andr​​oid闪烁？ [英] web view content flickering in android?

问题描述

我使用这 lib中横向轻扫。检查低于code

I'm using this lib for horizontal swipe. Check the below code

刷卡功能工作正常，但当我要去直接滑动则不会显示在Web视图内容。
显示出一些图片下面更多细节： -

Swipe functionality works fine but when i'm going direct to slide then doesn't show content on web view. Shown some below pic for more detail:-

在上面的图片当过我是刷卡它的作品不错，但如果我们想直接进入下一张幻灯片然后对着消失内容的问题如下： -

After above pic when ever i'm swipe it works nice but when we want to going directly into next slide then facing content disappear problem shown below :-

，然后它显示下面

code

PageControl mPageControl = (PageControl) findViewById(R.id.page_control);
    mSwipeView = (SwipeView) findViewById(R.id.swipe_view);

    mSwipeView.setPageControl(mPageControl);

    for (int i = 0; i < 10; i++) {
        mSwipeView.addView(new FrameLayout(this));
    }

    for (int i = 0; i < 10; i++) {

        ((FrameLayout) mSwipeView.getChildContainer().getChildAt(i))
                .addView(setupView());
        count++;
    }

setupView函数（）

public View setupView() {

    LayoutInflater layoutInflator = getLayoutInflater();
    LinearLayout childlayout = (LinearLayout) layoutInflator.inflate(
            R.layout.webview, Switcher, false);

            // adding all the things in which define in below XML

    return childlayout;

}

也抬高XML的@ + ID / option_main下面的xml：

also inflate xml on "@+id/option_main" with below xml :
