Android强制使用WebView不调用系统或外部浏览器
HTML5 HYBIRD混合APP需要在H5页面中打开第三方网站(例如:百度),android默认不在当前WebView中打开,反而会调用系统或外部浏览器,解决办法是自己重写WebViewClient,覆盖shouldOverrideUrlLoading并让其返回True。
实现代码
mWebView.setWebViewClient(new WebViewClient() { public boolean shouldOverrideUrlLoading(WebView view, String url) { // webview自己加载URL,让后通知系统不需要HandleURL view.loadUrl(url); return true; } }); |
原因可以从Android源代码中可知,True if the host application wants to leave the current WebView and handle the url itself, otherwise return false。
/** Give the host application a chance to take over the control when a new url is about to be loaded * in the current WebView. If WebViewClient is not provided, by default WebView will ask Activity * Manager to choose the proper handler for the url. If WebViewClient is provided, return true means * the host application handles the url, while return false means the current WebView handles the url. * This method is not called for requests using the POST "method". @param view The WebView that is initiating the callback. @param url The url to be loaded. @return True if the host application wants to leave the current WebView and handle the url itself, otherwise return false. */ public boolean shouldOverrideUrlLoading(WebView view, String url) { return false; } |
需要注意一点问题,如果你的代码中有拨打电话(tel:),发送邮件(mailto:)的话,需要在实现代码时对URL简单筛选一下才好
