WebView无限扩展 - 如何防止这种情况？

Nar*_*Gar 7 android infinite expansion webview

我在我的Android应用程序中使用webview,但是在它完成加载后 - 我可以通过onPageFinished(WebView webview,String url)检测到 - 页面继续无限增长.

我怎样才能防止这种情况发生？

这就是我的工作.

  1. 我有一个包含ScrollView的通用页面模板.宽度和高度设置为与父级匹配.在ScrollView中,我创建的所有活动都有几个常见元素.其中一个是LinearLayout,我插入所有用户内容.

    .....
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:layout_margin="0dp"
android:padding="0dp"
android:scrollbars="none"
>

......

<LinearLayout 
        android:id="@+id/content"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_margin="0dp"
        android:padding="0dp"
        android:orientation="vertical">

        //EVERY USER CONTENT GOES HERE    

</LinearLayout>


......

</ScrollView>

    .....

  2. 在此特定情况下,内容是网页,使用移动网络API加载Google地图.这是布局文件

    <?xml version="1.0" encoding="utf-8"?>

  <WebView
       android:id="@+id/maps"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:layout_centerInParent="true"
       android:layout_margin="0dp"
       android:padding="0dp"
  />

  3. 这是我的活动的代码,初始化webview

    .... WebView wv =(WebView)this.content.findViewById(R.id.maps);

    WebSettings ws = wv.getSettings();

    ws.setPluginState(PluginState.ON);
ws.setSupportZoom(false);
ws.setLightTouchEnabled(true);
ws.setDomStorageEnabled(true);
ws.setAppCacheMaxSize(1024 * 1024 * 8);
ws.setAppCachePath(context.getCacheDir().getAbsolutePath());
ws.setAppCacheEnabled(true);
ws.setAllowFileAccess(true);
ws.setCacheMode(WebSettings.LOAD_NORMAL);
ws.setJavaScriptEnabled(true);

wv.setInitialScale(0);
wv.addJavascriptInterface(new Object(), "Android");
wv.setKeepScreenOn(true);

  4. 最后,当我通过wv.loadUrl("......")加载地图时;

页面完成加载后,我得到以下日志,webview在无限循环中增长

我注意到当页面包含jQuery时会发生这种情况.但同样的页面在库存浏览器中加载正常.

知道为什么会这样,以及如何纠正这个问题？

任何有意义的帮助表示赞赏...谢谢.

这是一个迟到的答案,但希望它可以帮助某人.我遇到了同样的问题,罪魁祸首是这个底层的CSS:

body {
    width: 100%;    
    height: 100%;
}

此更改解决了以下问题:

你尝试过 android:layout_height="50dip"

传递 height 属性的值，而不是使用 wrap_content

  • 嗯，看来 ScrollView 和 WebView 不能一起使用 - 就这样。我尝试在滚动视图之外使用网络视图（这极大地改变了我的开发模板的结构） - 它有效。但这并不能解释无限增长仅发生在具有 jQuery 的页面中的事实 (2认同)
