Question

美好的一天！

我有一个WebView，你得到一个json，我打算将webview作为接收数据挂载，这部分代码＆＃34; html + =＆＃34; ＆＃34; + nmTitle +＆＃34; ＆＃34 ;;＆＃34; 我把接收json内容的变量放在这个部分＆＃34; nmTitle = object.optString（＆＃34; nmTitle＆＃34;）＆＃34;，它高于接收json的处理程序中的代码。但是，我的WebView不是接收分配的内容，而是将标题显示为＆＃34; null＆＃34;，看来，他携带WebView以便以后接收json，如何更改它为他分配内容然后发送到html？

public class InfoFragment extends Activity {
private AbstractNetworkHandler handler;
String nmTitle;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fragment_activities_list2);
    final WebView wv = new WebView(this);

    final LinearLayout ll = (LinearLayout) findViewById(R.id.LinearLayout1);
    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    wv.setLayoutParams(lp);

    //this.handler = AbstractNetworkFactory.build(this, NetworkAction.WEB_VIEW);
    this.handler = AbstractNetworkFactory.build(super.getBaseContext(), NetworkAction.WEB_VIEW);
    Log.i("webview", "ate aki foi");

    handler.get(23L, new HttpJsonObjectListener() {

        @Override
        public void onRequestCompleted(final JSONObject object, Integer httpStatus, CharSequence msg) {
            // final JSONArray array = object.optJSONArray("searchResultsCollection");
            nmTitle = object.optString("nmTitle");

            final JSONArray array = object.optJSONArray("searchResultsCollection");

            String s = String.valueOf(nmTitle);

            // json.setText("My Awesome Text");
            Log.i("webview", s);
            Log.i("webview", "recebendo json");
        }

    }, new HttpFailListener() {
        @Override
        public void onRequestCompleted(Exception e, Integer httpStatus, CharSequence msg) {
            Log.i("webview", "falhou ao obter json");
        }
    });
    // (WebView) findViewById(R.id.webView1);
    WebSettings ws = wv.getSettings();
    ws.setJavaScriptEnabled(true);
    ws.setSupportZoom(false);

    // wv.loadUrl("http://www.thiengo.com.br/img/system/logo/thiengo-80-80.png");
    String html = "<html>";
    html += "<body>";
    html += "<h1>" + nmTitle + "</h1>";
    html += "<img src=\"http://www.exemplo.com.br/img/system/logo/-80-80.png\" style=\"float: left; display: block; margin-right: 10px;\" />";
    for(int i = 0; i < 3; i++) {
        html += "<h3 id=\"h3\" style=\"float: left;\">Texto auxiliar " + (i + 1) + "</h3>";
    }
    html += "<script type=\"text/javascript\">";
    html += "document.getElementById('h3').style.color = '#ff0000';";
    html += "</script></body></html>";

    wv.loadData(html, "text/html", "UTF-8");
    ll.addView(wv);

}

}
