所有已实现的接口:

CefLoadHandler

public abstract class CefLoadHandlerAdapter
extends java.lang.Object
implements CefLoadHandler

An abstract adapter class for receiving load events. The methods in this class are empty. This class exists as convenience for creating handler objects.

用于接收加载事件的抽象适配器类。此类中的方法为空。此类存在是为了创建处理程序对象的便利。

onLoadEnd

public void onLoadEnd(CefBrowser browser,
                      CefFrame frame,
                      int httpStatusCode)

从接口复制的说明: CefLoadHandler

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.

在浏览器加载完帧后调用。 frameIdentifer值永远不会为空。可以同时加载多个帧。在主帧加载结束后，子帧可以开始或继续加载。无论请求是否成功完成，都将始终为所有帧调用此方法。

指定者:

onLoadEnd 在接口中 CefLoadHandler

参数:

browser - The affected browser. - 受影响的浏览器。

frame - The loading frame. - 装载框架。

httpStatusCode - The status code of the load. - 负载的状态代码。

onLoadError

public void onLoadError(CefBrowser browser,
                        CefFrame frame,
                        CefLoadHandler.ErrorCode errorCode,
                        java.lang.String errorText,
                        java.lang.String failedUrl)

从接口复制的说明: CefLoadHandler

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

在导航的资源加载失败或被取消时调用。

指定者:

onLoadError 在接口中 CefLoadHandler

参数:

browser - The affected browser. - 受影响的浏览器。

frame - The loading frame. - 装载框架。

errorCode - The error code number. - 错误代码编号。

errorText - The error text. - 错误文本。

failedUrl - The URL that failed to load. - 无法加载的URL。

onLoadingStateChange

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

从接口复制的说明: CefLoadHandler

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.

加载状态发生变化时调用。此回调将执行两次 - 一次以编程方式或通过用户操作启动加载，一次由于完成而终止加载，取消失败。

指定者:

onLoadingStateChange 在接口中 CefLoadHandler

参数:

browser - The affected browser. - 受影响的浏览器。

isLoading - true if it is loading. - 如果正在加载，则为true。

canGoBack - true if you can navigate back. - 如果您可以返回，则为true。

canGoForward - true if you can navigate forward. - 如果您可以向前导航，则为true。

onLoadStart

public void onLoadStart(CefBrowser browser,
                        CefFrame frame,
                        CefRequest.TransitionType transitionType)

从接口复制的说明: CefLoadHandler

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.

在浏览器开始加载帧时调用。 frameIdentifer值永远不会为空。可以同时加载多个帧。在主帧加载结束后，子帧可以开始或继续加载。如果该帧的加载请求失败，则可能不会为特定帧调用此方法。对于整体浏览器加载状态的通知，请改用OnLoadingStateChange。

指定者:

onLoadStart 在接口中 CefLoadHandler

参数:

browser - The affected browser. - 受影响的浏览器。

frame - The loading frame. - 装载框架。

transitionType - The transition type - 过渡类型
