使用查询将图像加载到Webview中会导致NullPointerEx

我正在使用Android Studio。

AQ版本：编译组：“ com.googlecode.android-query”，名称：“ android-query”，版本：“ 0.25.9”

几个月前，我在eclipse项目中使用了相同的技术，并且有效：(。

在片段的onActivityCreated中：

     aq = new AQuery(getActivity(), this.getView());
    String url = "http://farm4.static.flickr.com/3531/3769416703_b76406f9de.jpg";
    aq.id(R.id.image_webview).progress(R.id.progress).webImage(url);

我试图将代码放入具有相同结果的onCreateView中。

AQ源代码

private static String getSource(Context context){
    if(template == null){
        try{
            InputStream is = context.getClassLoader().getResourceAsStream("com/androidquery/util/web_image.html");          
            template = new String(AQUtility.toBytes(is));
        }catch(Exception e){
            AQUtility.debug(e);
        }
    }
    return template;
}
 private void setup(){
    String source = getSource(wv.getContext());
LINE 147:       String html = source.replace("@src", url).replace("@color", Integer.toHexString(color));
    .....
}

看来AS在加载web_image.html时遇到了麻烦。

谢谢您的所有回复！！！
