Détection de L'erreur de Webview et affichage du Message
j'aimerais afficher un message d'erreur quand il y a une erreur lors du chargement d'une page webview (pas de connexion). C'est ce que j'ai jusqu'à présent, sans le code de gestion des erreurs:
public class TrackerPage extends Activity {
// @Override
private WebView webview;
private ProgressDialog progressDialog;
private boolean error;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get rid of the android title bar
requestWindowFeature(Window.FEATURE_NO_TITLE);
// Set the XML layout
setContentView(R.layout.tracker_page);
// Bundle objectbundle = this.getIntent().getExtras();
webview = (WebView) findViewById(R.id.tracker);
final Activity activity = this;
// Enable JavaScript and lets the browser go back
webview.getSettings().setJavaScriptEnabled(true);
webview.canGoBack();
webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onLoadResource(WebView view, String url) {
// Check to see if there is a progress dialog
if (progressDialog == null) {
// If no progress dialog, make one and set message
progressDialog = new ProgressDialog(activity);
progressDialog.setMessage("Loading please wait...");
progressDialog.show();
// Hide the webview while loading
webview.setEnabled(false);
}
}
public void onPageFinished(WebView view, String url) {
// Page is done loading;
// hide the progress dialog and show the webview
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
webview.setEnabled(true);
}
}
});
// The URL that webview is loading
webview.loadUrl("http://url.org/");
}
}
comment je ferais ça?

Toutes les réponses ci-dessus sont obsolètes. Vous devez utiliser ce code après avoir terminé
@Override
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error){
//Your code to do
Toast.makeText(getActivity(), "Your Internet Connection May not be active Or " + error , Toast.LENGTH_LONG).show();
}

Vous êtes la plupart du chemin... Mettre en œuvre onReceivedError
et gérer les erreurs que vous voulez.

Ajouter cet après onpagefinished :
public void onReceivedError(WebView view, int errorCod,String description, String failingUrl) {
Toast.makeText(Webform.this, "Your Internet Connection May not be active Or " + description , Toast.LENGTH_LONG).show();
}
N'oubliez pas d'importer android.widget.Toast;

public class WebClient extends WebViewClient {
@Override
@TargetApi(Build.VERSION_CODES.M)
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
super.onReceivedError(view, request, error);
final Uri uri = request.getUrl();
handleError(view, error.getErrorCode(), error.getDescription().toString(), uri);
}
@SuppressWarnings("deprecation")
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
super.onReceivedError(view, errorCode, description, failingUrl);
final Uri uri = Uri.parse(failingUrl);

}
private void handleError(WebView view, int errorCode, String description, final Uri uri) {
final String host = uri.getHost();// e.g. "google.com"
final String scheme = uri.getScheme();// e.g. "https"
// TODO: logic
