解决webview内的iframe中的事件不可用的问题
最近做Android的Webview开发，使用iframe中嵌入了很多页面，嵌入的页面却不可用，最后发现是
webView.setWebViewClient(newWebViewClient(){
@Override
publicbooleanshouldOverrideUrlLoading(WebViewview,Stringurl){
returnsuper.shouldOverrideUrlLoading(view,url);
}
不要覆写
shouldOverrideUrlLoading
这个方法，覆写这个方法会拦截ifame中的事件。
补充知识：Android原生WebView访问使用iFrame网页问题（页面找不到了）
问题：
项目使用原生WebView访问使用了iFrame的网页出现的问题，列表页使用iFrame跳转到淘宝客的地址，单独访问淘宝客地址是能够打开。但列表页跳转过去总是提示“页面找不到了”，尝试很多方法，最终发现是WebView对第三方Cookie支持的问题。
解决：
if(android.os.Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP)
CookieManager.getInstance().setAcceptThirdPartyCookies(mWebView,true);
完整配置：
mWebView.setWebViewClient(newWebViewClient(){
@Override
publicvoidonPageStarted(WebViewview,Stringurl,Bitmapfavicon){
super.onPageStarted(view,url,favicon);
}
@Override
publicvoidonReceivedSslError(WebViewview,SslErrorHandlerhandler,SslErrorerror){
handler.proceed();
super.onReceivedSslError(view,handler,error);
}
@Override
publicbooleanshouldOverrideUrlLoading(WebViewview,Stringurl){returnsuper.shouldOverrideUrlLoading(view,url);
}
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
@Override
publicWebResourceResponseshouldInterceptRequest(WebViewview,WebResourceRequestrequest){
returnsuper.shouldInterceptRequest(view,request);
}
@Override
publicvoidonPageFinished(WebViewview,Stringurl){
super.onPageFinished(view,url);
if(null!=title&&null!=view&&TextUtils.isEmpty(mTitle))
title.setText(view.getTitle());
}
});
mWebView.setWebChromeClient(newWebChromeClient(){
@Override
publicvoidonProgressChanged(WebViewwebView,inti){
super.onProgressChanged(webView,i);
}
@Override
publicbooleanonJsConfirm(WebViewview,Stringurl,Stringmessage,android.webkit.JsResultresult){
returnsuper.onJsConfirm(view,url,message,result);

@Override
