stopLoading（）真的在做什么？

是的，我知道stopLoading()的文件说，“停止当前的负载。”stopLoading（）真的在做什么？

但是当我尝试用它来停止当前负荷加载一个新的进展之前页面，它似乎并没有表现as desired：

07-24 12:53:30.177: V/WebView.loadUrl: http://www.google.com 
07-24 12:53:30.227: V/WebViewClient.onPageStarted: http://www.google.com 

===> WebView.stopLoading() called here <==== 

07-24 12:53:31.917: V/WebView.loadUrl: http://www.stackoverflow.com 
07-24 12:53:32.697: V/WebViewClient.onPageFinished: http://www.google.com 

07-24 12:53:32.767: V/WebViewClient.onPageStarted: http://www.stackoverflow.com 
07-24 12:53:33.587: V/WebViewClient.onPageFinished: http://www.stackoverflow.com

正如你可以在日志中看到，WebViewClient.onPageFinished()第一个loadUrl()被调用尽管WebView.stopLoading()被称为大约1秒较早。

这是为什么？

stopLoading()确实是做什么的？

我猜它只是设置一个标志，告诉WebView不要运行像onPageFinished等任何钩子，我不认为它会实际上停止网络连接。 – you786 2012-08-02 19:34:40

you786是正确的：

public void stopLoading() { 
    checkThread(); 
    // TODO: should we clear all the messages in the queue before sending 
    // STOP_LOADING? 
    switchOutDrawHistory(); 
    mWebViewCore.sendMessage(EventHub.STOP_LOADING); 
}

对于TODO他们在剩余的消息标志着在会首先得到处理。这样的结果是什么，我只是好奇：在

WebViewClient.onReceivedError(WebView view, int errorCode, String description, String failingUrl)

停止负载时的WebView并没有真正停止，而是加载自己的404页（什么，如果你不叫stopLoading通常会做（））：
