React Native-在导航到包含嵌入在自己的web视图中的多条tweet的页面后取消对空指针的引用

react-native-webview react-navigation react-native-android twitter react-native

我目前为工作而开发的应用程序主要集中在显示文章上。其中一些包含Twitter嵌入(在web版本上),由于API由我们的两个应用程序共享,因此我也将嵌入作为HTML接收。每当我试图在WebView中显示tweets,并将源代码设置为HTML和Twitter JS脚本以进行样式设置时,页面要么正确加载,但在我按back(使用react导航)时崩溃,要么只是加载时崩溃,但仅在ANDROID上崩溃。

我试过以下方法:

package 而不是内置的。我开了一个 issue
从WebView中删除JS脚本。
injectedJavaScript 代替道具。

这就是我呈现网络视图的方式:

const JS = '<script type="text/javascript" src="https://platform.twitter.com/widgets.js"></script>';
return (
    <View
        key={content.embed._id} 
        style={[{ overflow : "hidden", marginTop : 15, marginStart : 15 }]}>
        <WebView 
            scrollEnabled={false}
            style={{ height : 150, width : Dimensions.get('window').width - 30 }}
            source={{ html : content.embed.html + JS }} />
    </View>
);

这是来自Android Studio的堆栈跟踪(我甚至没有红盒,只是一个普通的旧硬崩溃)。

所以我在社区支持的WebView github页面上做了更多的研究,结果发现 androidHardwareAccelerationDisabled 这是一个 boolean . 我试着把它设置成 true 它似乎已经解决了这个问题!

<Webview
    androidHardwareAccelerationDisabled={true}
    ... />
