Wie verwende ich Webview?

Question

String fbid = getIntent().getStringExtra("id");//Getting this value from previous screen 

    Log.e("What I am getting : " + fbid); 


    final String url = "https://www.fbbexample.com/abc/"+fbid; //**not working** 

Log.e("url I am getting : " + url); Log value: https://www.fbbexample.com/abc/59 



// final String url2 = "https://www.fbbexample.com/abc/"+59; //**this is working** 

    // Log.e("url2 I am getting : " + url2); Log value: https://www.fbbexampl.com/abc/59 

    webView = (WebView) findViewById(R.id.webView);  



    webView.getSettings().setJavaScriptEnabled(true); 

    webView.loadUrl(url); 

    webView.getSettings().setBuiltInZoomControls(true); 

    webView.setWebViewClient(new WebViewClient() { 

     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, String url) { 
      view.loadUrl(url); 
      // webView.getSettings().setBuiltInZoomControls(true); 
      return true; 
     } 
    }); 
} 
} 

Was ich bin vor, wenn ich hart Code die Zeichenfolge „FBID“ es funktioniert und wenn ich versuche, es wie erwähnt oben dann leeren Bildschirm bekommen .. ....

Intent Absicht = new Intent (getContext(), SingleFbb.class);
intent.putExtra ("id", idno);

      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_show_subject_list_items_in_web_view); 
      this.initViews(); 
      String fbid = getIntent().getStringExtra("idmindmaps"); 
      url= "https://www.fbbexample.com/abc/"+fbid; 
      loadWebView(url); 
     } 

     //initializes all views 
     private void initViews() { 
      webView = (WebView) findViewById(R.id.filesWebView); 
     } 

     //show Url in WebView 
     public class myWebClient extends WebViewClient { 
      @JavascriptInterface 
      @Override 
      public void onPageStarted(WebView view, String url, Bitmap favicon) { 
       // TODO Auto-generated method stub 
       super.onPageStarted(view, url, favicon); 
       dialog = new ProgressDialog(ShowSubjectListItemsInWebView.this); 
       dialog.setProgressStyle(android.R.style.Widget_ProgressBar_Small); 
       dialog.setCancelable(false); 
       dialog.setMessage(Constant.KEY_PLEASE_WAIT); 
       dialog.show(); 
      } 

      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       // TODO Auto-generated method stub 
       view.loadUrl(url); 
       return true; 
      } 

      @Override 
      public void onPageFinished(WebView view, String url) { 
       // TODO Auto-generated method stub 
       super.onPageFinished(view, url); 
       if (dialog.isShowing()) { 
        dialog.dismiss(); 
       } 
      } 
     } 

     public void loadWebView(String url) { 
      webView.setWebViewClient(new myWebClient()); 
      webView.getSettings().setJavaScriptEnabled(true); 
      webView.getSettings().setBuiltInZoomControls(true); 
      webView.getSettings().setUseWideViewPort(true); 
      webView.getSettings().setLoadWithOverviewMode(true); 
      webView.getSettings().setDomStorageEnabled(true); 
      webView.setVisibility(View.VISIBLE); 
      webView.loadUrl(url); 
     } 

    } 

Answer 2

Versuchen Sie dies. Dadurch werden die Leerräume,

Sie auch falsche Schlüssel verwenden, um Wert von vorherigen Bildschirm zu erhalten. richtigen Schlüssel in Ihrem Code ist "idmindmaps" so verwenden Sie dies.

String fbid = getIntent().getStringExtra("idmindmaps");
