Come faccio a disattivare la mia finestra di avanzamento dopo aver caricato Webview?

Question

Cosa è necessario al mio codice per rendere la finestra di dialogo dismiss() dopo aver caricato la webview?

public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 
      CookieSyncManager.createInstance(this); 
      CookieSyncManager.getInstance().startSync(); 
      webview = (WebView) findViewById(R.id.webview); 
      webview.setWebViewClient(new homeClient()); 
      webview.getSettings().setJavaScriptEnabled(true); 
      webview.getSettings().setPluginsEnabled(true); 
      webview.loadUrl("http://google.com"); 

      ProgressDialog pd = ProgressDialog.show(Home.this, "", 
        "Loading. Please wait...", true); 

     } 

Ho provato

public void onPageFinshed(WebView view, String url){ 
     pd.dismiss(); 
    } 

Non ha funzionato.

: o webview.setWebViewClient (nuova homeClient()); homeClient() ????

provare questo aggiornamento

... 
... 
... 

webview = (WebView) findViewById(R.id.webview); 
webview.setWebViewClient(new WebViewClient() { 
      public boolean shouldOverrideUrlLoading(WebView view, String url) {    
       view.loadUrl(url); 
       return true; 
      } 


      public void onPageFinished(WebView view, String url) { 
       if (progressBar.isShowing()) { 
        progressBar.dismiss(); 
       } 
      } 
webview.loadUrl("http://www.google.com"); 

} 

:: questo è un buon esempio.

Come si accede a pd in onPageFinshed()? (E sei sicuro che in realtà è chiamato al caricamento della pagina?)

Nella tua onCreate(), provare passando pd al vostro homeClient modo che homeClient può prendersi cura di chiudere la finestra di.

tuo homeClient dovrebbe essere simile a questo:

private class homeClient extends WebViewClient { 

    private ProgressDialog pd; 

    public homeClient(ProgressDialog pd) { 
     this.pd = pd; 
    } 

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

    @Override 
    public void onPageFinished (WebView view, String url) { 
     if (pd.isShowing()) { 
      pd.dismiss(); 
     } 
    } 
} 

Nel vostro onCreate():

ProgressDialog pd = ProgressDialog.show(Fbook.this, "", 
       "Loading. Please wait...", true); 
webview.setWebViewClient(new homeClient(pd));

Questo è OK.

public class WordActivity extends Activity { 

    private WebView webview; 
    private ProgressDialog progressDialog; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.webview); 
     Bundle objetbunble = this.getIntent().getExtras(); 
     webview = (WebView) findViewById(R.id.webview); 

     final Activity activity = this; 

     webview.getSettings().setJavaScriptEnabled(true); 

     webview.setWebViewClient(new WebViewClient() { 
      public boolean shouldOverrideUrlLoading(WebView view, String url) {    
       view.loadUrl(url); 
       return true; 
      } 
      public void onLoadResource (WebView view, String url) { 
       if (progressDialog == null) { 
        progressDialog = new ProgressDialog(activity); 
        progressDialog.setMessage("Chargement en cours"); 
        progressDialog.show(); 
       } 
      } 
      public void onPageFinished(WebView view, String url) { 
       if (progressDialog.isShowing()) { 
        progressDialog.dismiss(); 
        progressDialog = null; 
       } 
      } 
     }); 
     webview.loadUrl("http://www.example.com"); 
    } 


}

@Jorgesys questo non è preciso al 100%. Se hai diversi iframe in una pagina avrai più onPageFinished (e onPageStarted). E se hai diversi reindirizzamenti, potrebbe anche fallire. Questo approccio penso che risolve tutti i problemi:

boolean loadingFinished = true; 
boolean redirect = false; 

mWebView.setWebViewClient(new WebViewClient() { 

    @Override 
    public boolean shouldOverrideUrlLoading(WebView view, String urlNewString) { 
     if (!loadingFinished) { 
      redirect = true; 
     } 

    loadingFinished = false; 
    webView.loadUrl(urlNewString); 
    return true; 
    } 

    @Override 
    public void onPageStarted(WebView view, String url) { 
     loadingFinished = false; 
     //SHOW LOADING IF IT ISNT ALREADY VISIBLE 
    } 

    @Override 
    public void onPageFinished(WebView view, String url) { 
     if(!redirect){ 
      loadingFinished = true; 
     } 

     if(loadingFinished && !redirect){ 
     //HIDE LOADING IT HAS FINISHED 
     } else{ 
      redirect = false; 
     } 

    } 
});

Se si vuole semplicemente per mostrare i progressi prima del caricamento pagina web in WebView. Si può semplicemente richiedere Caratteristica finestra di avanzamento come

getWindow().requestFeature(Window.FEATURE_PROGRESS); 

prima setContentView(R.layout.blahblah);

e mostrarlo progredire nella onProgressChanged come

final Activity context= this; 
webview.setWebChromeClient(new WebChromeClient() 
{ 
    public void onProgressChanged(WebView webView, int progress) 
    { 
    activity.setProgress(progress * 1000); 
    } 
}); 

E se si desidera aggiungere il proprio ProgressDialog quindi utilizzare WebviewClient

webView.setWebViewClient(new WebViewClient() { 
    ProgressDialog rogressDialog ; 
    @Override 
    public void onPageStarted(WebView view, String url, Bitmap bitmap) { 
     progressDialog = ProgressDialog.show(context, "Loading...", "Please wait...");//where context = YourActivity.this; 
     super.onPageStarted(view, url, bitmap); 
    } 

    @Override 
    public void onPageFinished(WebView view, String url) { 
     progressDialog .dismiss(); 
     super.onPageFinished(view, url); 
    } 
}); 

webView.loadUrl(url);

wv1.setWebViewClient(new WebViewClient() { 
      public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
       Toast.makeText(Entertainment.this, description, Toast.LENGTH_SHORT).show(); 
      } 

      @Override 
      public void onPageStarted(WebView view, String url, Bitmap favicon) 
      { 
       progressDialog.show(); 
      } 


      @Override 
      public void onPageFinished(WebView view, String url) { 
       progressDialog.dismiss(); 
       String webUrl = wv1.getUrl(); 

      } 

     }); 

    wv1.loadUrl(url); 

Il codice qui sopra mostra un dialogo di progresso per ogni link in entrata si naviga al di WebView.
