如何传递 html 字符串到 android 上的 webview？

我正在解析 xml，然后将其加载到 Web 视图。解析之后，我将创建四个字符串，以便将所有字符串附加到一个视图。我能够在 Web 视图上获得两个视图，但是不能获得前两个字符串。

请在我的代码中建议，我在哪里出错了，以及正确的方式获得网页视图中格式化的 html 字符串。

@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
String chapterTitle = "";
String SubChapterTitle="";
String chapterIntro ="";
String chapterContent="";
View view = convertView;
if (convertView == null) {
// view = inflater.inflate(resourceid, null);
view = getLayoutInflater().inflate(R.layout.webviewitem, null);
}
synchronized (view) {
WebView wv = (WebView) view.findViewById(R.id.contentWebView);


WebSettings settings = wv.getSettings();
settings.setUseWideViewPort(true);
settings.setLoadWithOverviewMode(true);
settings.setJavaScriptEnabled(true);
settings.setDefaultZoom(ZoomDensity.FAR);
// wv.setBackgroundColor(0);
wv.setVerticalScrollBarEnabled(false);
wv.setHorizontalScrollBarEnabled(false);
/*String txtChapTitle = Intro.book.getsecretList().get(position)
.getChtitle().toString();*/
            

if (!(Intro.book.getsecretList().get(position).getChtitle()
.toString().equals(""))){
chapterTitle = "<b><fontSize=4>"+Intro.book.getsecretList().get(position)
.getChtitle().toString()+"</font></b>";
}
if (!(Intro.book.getsecretList().get(position)
.getSubtitle() == null)) {
SubChapterTitle = "<b><fontSize=4>"+Intro.book.getsecretList().get(position)
.getSubtitle().toString()+"</font></b>";
}
if (!(Intro.book.getsecretList().get(position)
.getIntro() == null)) {
chapterIntro = "<b><fontSize=2>"+Intro.book.getsecretList().get(position)
.getIntro().toString()+"</font></b>";
}
if (!(Intro.book.getsecretList().get(position)
.getContent() == null)) {
chapterContent = "<fontSize=2>"+Intro.book.getsecretList().get(position)
.getContent().toString()+"</font>";
}
            

StringBuilder content = new StringBuilder();
content.append(chapterTitle+SubChapterTitle+chapterIntro+chapterContent);
            

JsInterface Jsi = new JsInterface();
Jsi.wordDef = content ;
Log.v("Content", "" +content);
wv.addJavascriptInterface(Jsi, "interfaces");


wv.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
view.setHapticFeedbackEnabled(false);
}
});


wv.setWebChromeClient(new WebChromeClient() {
@Override
public boolean onJsAlert(WebView view, String url,
String message, JsResult result) {
return super.onJsAlert(view, url, message, result);
}
});
            

wv.loadUrl("file:///android_asset/wordview.html");
}
return view;
}
}

我能够得到 chapterIntro和 chaptercontent的网络视图，但不是前两个字符串。
