ScrollView里面的Android WebView只滚动scrollview [英] Android WebView inside ScrollView scrolls only scrollview

问题描述

在我的应用程序中，我有一个 ScrollView，其中包含一些线性视图、一些文本视图和一个 Web 视图，然后是其他线性布局等.问题是 WebView 不滚动.Scroll 只在 ScrollView 上监听.有什么建议吗??

In my app I have a ScrollView that contains some linearviews, some textviews and One Webview, then other linear layouts etc. The problem is that the WebView does not scroll. The Scroll listens only on ScrollView. Any suggestions??

<ScrollView >
    <TextView />
    <WebView />              <-- this does not scroll
    <TextView />
</ScrollView >

推荐答案

这里是解决方案.网上找的.我已经对 WebView 进行了子类化，并且正在使用 requestDisallowInterceptTouchEvent(true); 方法来允许我的 webview 处理滚动事件.

Here is the solution. Found online. I have subclassed WebView and i'm using the requestDisallowInterceptTouchEvent(true); method to allow my webview to handle the scroll event.

TouchyWebView.java

TouchyWebView.java

package com.mypackage.common.custom.android.widgets

public class TouchyWebView extends WebView {

    public TouchyWebView(Context context) {
        super(context);
    }

    public TouchyWebView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public TouchyWebView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event){
        requestDisallowInterceptTouchEvent(true);
        return super.onTouchEvent(event);
    }          
}

在 layout.xml 中

And in layout.xml

<com.mypackage.common.custom.android.widgets.TouchyWebView 
                android:id="@+id/description_web"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                 />
