如何解析Fragment中的Jsoup数据(WebView)

How to Parse Jsoup data in Fragment (WebView)

这是我的 fragment.There 没有错误之类的,但是当我打开片段时仍然是空白屏幕。 我怎样才能解决这个线程问题?我只想从 html 解析并在 WebView 中显示。

   @Override
public View onCreateView(LayoutInflater inflater, ViewGroup
        container, Bundle savedInstanceState) {
    rootview = inflater.inflate(R.layout.menu2_layout_duyurular, container, false);
    downloadThread.start();
    WvFun();
    return rootview;
}

Thread downloadThread = new Thread() {
    public void run() {
        try {
            doc = Jsoup.connect(url_duyurular).get();
            div = doc.select("#yazilar").get(0);
            data += div;
            Log.i("Words", data);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
};

    public void WvFun() {
        Log.i("Working Fine", "WvFun is working.");
        WebView webView = (WebView) rootview.findViewById(R.id.duyurular_page);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadData(data, "text/html", "utf-8");
    }

我的logcat。如您所见,logcat 中没有错误。但是 "Working Fine" 日志早于 "Words" Log.How 我可以解决这个问题吗?我应该如何使用线程。

现在我可以解析并在 webview 上显示了。

@Override

    final WebView webView = (WebView) rootview.findViewById(R.id.duyurular_page);
    webView.getSettings().setJavaScriptEnabled(true);
   // webView.addJavascriptInterface(new MyJavaScriptInterface(this), "HtmlViewer");
    downloadThread.start();
    webView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageFinished(WebView view, String url) {
            webView.loadData(data, "text/html", null);
        }
    });

    webView.loadUrl(url_duyurular);

    return rootview;
}

Thread downloadThread = new Thread() {
    public void run() {
        try {

            doc = Jsoup.connect(url_duyurular).get();
