方法详细资料

onLoadingStateChange

void onLoadingStateChange(CefBrowser browser,
                        boolean isLoading,
                        boolean canGoBack,
                        boolean canGoForward)

Called when the loading state has changed. This callback will be executed twice -- once when loading is initiated either programmatically or by user action, and once when loading is terminated due to completion, cancellation of failure.

参数:

browser - The affected browser.

isLoading - true if it is loading.

canGoBack - true if you can navigate back.

canGoForward - true if you can navigate forward.

onLoadStart

void onLoadStart(CefBrowser browser,
               int frameIdentifer)

Called when the browser begins loading a frame. The frameIdentifer value will never be empty. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method may not be called for a particular frame if the load request for that frame fails. For notification of overall browser load status use OnLoadingStateChange instead.

参数:

browser - The affected browser.

frameIdentifer - The identifier of the loading frame.

onLoadEnd

void onLoadEnd(CefBrowser browser,
             int frameIdentifier,
             int httpStatusCode)

Called when the browser is done loading a frame. The frameIdentifer value will never be empty. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method will always be called for all frames irrespective of whether the request completes successfully.

参数:

browser - The affected browser.

frameIdentifer - The identifier of the loading frame.

onLoadError

void onLoadError(CefBrowser browser,
               int frameIdentifer,
               CefLoadHandler.ErrorCode errorCode,
               String errorText,
               String failedUrl)

Called when the resource load for a navigation fails or is canceled.

参数:

browser - The affected browser.

frameIdentifer - The identifier of the loading frame.

errorCode - The error code number.

errorText - The error text.

failedUrl - The URL that failed to load.
