Question

我想从服务器显示webview中的内容。数据来自服务器的html格式。如何在webview上这样。数据变量包含所有结果但我无法读取html内容。

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dashboard__description__page);
        WebView webView = (WebView) findViewById(R.id.webview);
        // String summary = "<html><body>You scored <b>192</b> points.</body></html>";
        webView.loadData(summary, "text/html", null);


        if (savedInstanceState == null) {
            Bundle extras = getIntent().getExtras();

            if(extras == null) {
                alternate_id= null;
                bookmarkid= null;
                bookmarkfile = null;
            } else {
                alternate_id= extras.getString("alternateid");
                bookmarkid= extras.getString("bookmarkid");
                bookmarkfile = extras.getString("bookmarkfile");

            }
        } else {
            alternate_id= (String) savedInstanceState.getSerializable("alternateid");
            bookmarkid= (String) savedInstanceState.getSerializable("bookmarkid");
            bookmarkfile= (String) savedInstanceState.getSerializable("bookmarkfile");

        }




        // System.out.println(stringCameFromFirstAcvitity);

      //  actorsList = new ArrayList<Actors>();
        new JSONReaderAsyncTask().execute("https://www.webmod.com/mydata/get_article_detail?", " access_token", "bookmark_file", "alternate_id", "bookmarkId");

        reader_back=(ImageButton)findViewById(R.id.reader_back_btn);
        reader_back.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent dash_back = new Intent(getApplicationContext(),Dashboard.class);
                startActivity(dash_back);

            }
        });


    }

    class JSONReaderAsyncTask extends AsyncTask<String, Void, Boolean> {

        ProgressDialog dialog;

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            dialog = new ProgressDialog(Dashboard_Description__page.this);
            dialog.setMessage("Loading, please wait");
            dialog.setTitle("Connecting server");
            dialog.show();
            dialog.setCancelable(false);


        }

        @Override
        protected Boolean doInBackground(String... params)

            String jsonResult = "";

                nameValuePairs.add(new BasicNameValuePair("alternate_id", alternate_id));
                nameValuePairs.add(new BasicNameValuePair("bookmarkId", bookmarkid));

               // System.out.println(alternate_id);
                //System.out.println(bookmarkfile);
               // System.out.println(bookmarkid);
                httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                HttpResponse response = httpClient.execute(httpPost);
                // System.out.println("hello Hitu");

                //  jsonResult = inputStreamToString(response.getEntity().getContent()).toString();

                if (status == 200) {
                    HttpEntity entity = response.getEntity();
                    String data = EntityUtils.toString(entity);

                    }

奥基。正如您所说，您希望在WebView中显示这些数据，这就是您可以做的事情。

wv = (WebView) findViewById(R.id.webView)
wv.loadDataWithBaseURL("", YOUR_TEXT, "text/html", "utf-8", "");

我希望这会有所帮助。
