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 publicvoidonShowCustomView(Viewview,CustomViewCallbackcallback){ super.onShowCustomView(view,callback); } @Override publicvoidonHideCustomView(){ } @Override publicbooleanonShowFileChooser(WebViewwebView,android.webkit.ValueCallbackfilePathCallback,FileChooserParamsfileChooserParams){ returnsuper.onShowFileChooser(webView,filePathCallback,fileChooserParams); } @Override publicbooleanonJsAlert(WebViewview,Stringurl,Stringmessage,android.webkit.JsResultresult){ returnsuper.onJsAlert(view,url,message,result); } @Override publicvoidonReceivedTitle(WebViewview,Stringtitle){ super.onReceivedTitle(view,title); } } ); WebSettingsmWebSettings=mWebView.getSettings(); mWebSettings.setAllowFileAccess(true); mWebSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS); mWebSettings.setSupportZoom(true); mWebSettings.setBuiltInZoomControls(true); mWebSettings.setUseWideViewPort(true); mWebSettings.setSupportMultipleWindows(false); mWebSettings.setAppCacheEnabled(true); mWebSettings.setDomStorageEnabled(true); mWebSettings.setJavaScriptEnabled(true); mWebSettings.setGeolocationEnabled(true); mWebSettings.setAppCacheMaxSize(Long.MAX_VALUE); mWebSettings.setAppCachePath(getDir("appcache",0).getPath()); mWebSettings.setDatabasePath(getDir("databases",0).getPath()); mWebSettings.setGeolocationDatabasePath(getDir("geolocation",0) .getPath()); mWebSettings.setPluginState(WebSettings.PluginState.ON_DEMAND); mWebSettings.setLoadWithOverviewMode(true); mWebSettings.setCacheMode(WebSettings.LOAD_NO_CACHE); StringmUserAgent=mWebSettings.getUserAgentString(); mWebSettings.setUserAgentString(mUserAgent+"App/AppName"); syncCookie(); mWebSettings.setUseWideViewPort(true); mWebSettings.setLoadWithOverviewMode(true); if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.KITKAT){ mWebSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK); }else{ mWebSettings.setCacheMode(WebSettings.LOAD_DEFAULT); } if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.HONEYCOMB){ mWebSettings.setDisplayZoomControls(false); } if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.KITKAT){ mWebSettings.setLoadsImagesAutomatically(true); }else{ mWebSettings.setLoadsImagesAutomatically(false); } if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP){ mWebSettings.setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW); } if(android.os.Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP) CookieManager.getInstance().setAcceptThirdPartyCookies(mWebView,true); mWebView.setScrollBarStyle(WebView.SCROLLBARS_INSIDE_OVERLAY); mWebView.setHorizontalScrollBarEnabled(false); mWebView.setHorizontalFadingEdgeEnabled(false); mWebView.setVerticalFadingEdgeEnabled(false); mWebView.requestFocus(); privatevoidsyncCookie(){ CookieSyncManager.createInstance(this); CookieManagercookieManager=CookieManager.getInstance(); cookieManager.setAcceptCookie(true); CookieSyncManager.getInstance().sync(); }
