Method Detail

shouldOverrideUrlLoading

public boolean shouldOverrideUrlLoading(WebView view,
                                        String url)
Give the host application a chance to take over the control when a new url is about to be loaded in the current WebView. If WebViewClient is not provided, by default WebView will ask Activity Manager to choose the proper handler for the url. If WebViewClient is provided, return true means the host application handles the url, while return false means the current WebView handles the url.

Parameters:
view - The WebView that is initiating the callback.
url - The url to be loaded.
Returns:
True if the host application wants to leave the current WebView and handle the url itself, otherwise return false.

onPageStarted

public void onPageStarted(WebView view,
                          String url,
                          Bitmap favicon)
Notify the host application that a page has started loading. This method is called once for each main frame load so a page with iframes or framesets will call onPageStarted one time for the main frame. This also means that onPageStarted will not be called when the contents of an embedded frame changes, i.e. clicking a link whose target is an iframe.

Parameters:
view - The WebView that is initiating the callback.
url - The url to be loaded.
favicon - The favicon for this page if it already exists in the database.

onPageFinished

public void onPageFinished(WebView view,
                           String url)
Notify the host application that a page has finished loading. This method is called only for main frame. When onPageFinished() is called, the rendering picture may not be updated yet. To get the notification for the new Picture, use WebView.PictureListener.onNewPicture(android.webkit.WebView, android.graphics.Picture).

Parameters:
view - The WebView that is initiating the callback.
url - The url of the page.

onLoadResource

public void onLoadResource(WebView view,
                           String url)
Notify the host application that the WebView will load the resource specified by the given url.

Parameters:
view - The WebView that is initiating the callback.
url - The url of the resource the WebView will load.

onTooManyRedirects

public void onTooManyRedirects(WebView view,
                               Message cancelMsg,
                               Message continueMsg)
Notify the host application that there have been an excessive number of HTTP redirects. As the host application if it would like to continue trying to load the resource. The default behavior is to send the cancel message.

Parameters:
view - The WebView that is initiating the callback.
cancelMsg - The message to send if the host wants to cancel
continueMsg - The message to send if the host wants to continue

onReceivedError

public void onReceivedError(WebView view,
                            int errorCode,
                            String description,
                            String failingUrl)
Report an error to an activity. These errors come up from WebCore, and are network errors.

Parameters:
view - The WebView that is initiating the callback.
errorCode - The HTTP error code.
description - A String description.
failingUrl - The url that failed.

onFormResubmission

public void onFormResubmission(WebView view,
                               Message dontResend,
                               Message resend)
As the host application if the browser should resend data as the requested page was a result of a POST. The default is to not resend the data.

Parameters:
view - The WebView that is initiating the callback.
dontResend - The message to send if the browser should not resend
resend - The message to send if the browser should resend data

doUpdateVisitedHistory

public void doUpdateVisitedHistory(WebView view,
                                   String url,
                                   boolean isReload)
Notify the host application to update its visited links database.

Parameters:
view - The WebView that is initiating the callback.
url - The url being visited.
isReload - True if this url is being reloaded.

onReceivedSslError

public void onReceivedSslError(WebView view,
                               SslErrorHandler handler,
                               SslError error)
Notify the host application to handle a ssl certificate error request (display the error to the user and ask whether to proceed or not). The host application has to call either handler.cancel() or handler.proceed() as the connection is suspended and waiting for the response. The default behavior is to cancel the load.

Parameters:
view - The WebView that is initiating the callback.
handler - An SslErrorHandler object that will handle the user's response.
error - The SSL error object.

onReceivedHttpAuthRequest

public void onReceivedHttpAuthRequest(WebView view,
                                      HttpAuthHandler handler,
                                      String host,
                                      String realm)
Notify the host application to handle an authentication request. The default behavior is to cancel the request.

Parameters:
view - The WebView that is initiating the callback.
handler - The HttpAuthHandler that will handle the user's response.
host - The host requiring authentication.
realm - A description to help store user credentials for future visits.

shouldOverrideKeyEvent

public boolean shouldOverrideKeyEvent(WebView view,
                                      KeyEvent event)
Give the host application a chance to handle the key event synchronously. e.g. menu shortcut key events need to be filtered this way. If return true, WebView will not handle the key event. If return false, WebView will always handle the key event, so none of the super in the view chain will see the key event. The default behavior returns false.

Parameters:
view - The WebView that is initiating the callback.
event - The key event.
Returns:
True if the host application wants to handle the key event itself, otherwise return false

onUnhandledKeyEvent

public void onUnhandledKeyEvent(WebView view,
                                KeyEvent event)
Notify the host application that a key was not handled by the WebView. Except system keys, WebView always consumes the keys in the normal flow or if shouldOverrideKeyEvent returns true. This is called asynchronously from where the key is dispatched. It gives the host application an chance to handle the unhandled key events.

Parameters:
view - The WebView that is initiating the callback.
event - The key event.

onScaleChanged

public void onScaleChanged(WebView view,
                           float oldScale,
                           float newScale)
Notify the host application that the scale applied to the WebView has changed.

Parameters:
view - he WebView that is initiating the callback.
