WebView水平滚动失败 [英] WebView horizontal scrolling fails

问题描述

片段中的WebView出现了一个奇怪的问题.水平滚动无法正常工作.它只滚动一点.没问题，可以垂直滚动内容，捏以缩放，是的，在捏住的同时用两根手指移动页面也可以在所有方向上使用.

I've got a strange issue with a WebView inside a fragment. The horizontal scrolling doesn't work properly. It scrolls only a bit. It's no problem, to scroll the content vertically, pinch to zoom, and yes, moving the page with two fingers while pinching also works in all directions.

这是Fragment的onCreateView()方法，带有WebView.我不能使用WebViewFragment. 该片段位于Viewpager中！提供的数据是有效的html5文档.但是我也没有成功尝试真实网页".

This is the onCreateView()-Method of the Fragment, that carries the WebView. I can't use WebViewFragment. This Fragment is inside a Viewpager! The provided data is a valid html5 document. But I've not successfully tried a "real webpage" as well.

this.mView = inflater.inflate(R.layout.search_results, container, false);
        mWebView = (WebView)this.mView.findViewById(R.id.search_results);
        mWebView.setWebViewClient(new SearchResultsWebViewClient());
        mWebView.setInitialScale(120);
        mWebView.setScrollContainer(true);
        mWebView.bringToFront();
        mWebView.setScrollbarFadingEnabled(true);
        mWebView.setVerticalScrollBarEnabled(true);
        mWebView.setHorizontalScrollBarEnabled(true);
        mWebView.getSettings().setBuiltInZoomControls(true);
        mWebView.getSettings().setJavaScriptEnabled(false);

        mWebView.loadData(this.data, "text/html", "utf-8");

        return this.mView;

这是search_results.xml

This is the search_results.xml

    <?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id ="@+id/search_results"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
</WebView>

以及加载片段的布局文件

And the layout-file in which the fragment is loaded

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
        android:baselineAligned="false"
        android:weightSum="1.0">

    <LinearLayout android:layout_weight="0.5"
                    android:layout_width="0dip"
                    android:layout_height="match_parent"
                    android:orientation="vertical" >        
<ListView android:id="@id/android:list"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:background="#000000"
           android:drawSelectorOnTop="false"/>
</LinearLayout>
     <LinearLayout android:layout_weight="0.5"
                android:layout_width="0dip"
                android:layout_height="match_parent"
                android:orientation="vertical" >
                <FrameLayout android:id="@+id/resultsWebWiewFragmentFrame"
                      android:layout_width="match_parent" 
                      android:layout_height="match_parent"/>
    </LinearLayout>
</LinearLayout>

由于我使用的是ABS，因此无法直接将片段加载到xml文件中.这将引发ClassCastException.

Because I'm using ABS, it isn't possible to load the fragment directly in the xml file. This'll throw a ClassCastException.
