推荐答案

设置 WebViewClient 到您的 webview 并覆盖

Set a WebViewClient to your webview and override shouldOverrideUrlLoading. Check if the url to be loaded is the one you want to intercept. If it is do what you want and return true, if its not, return false.

    webview.setWebViewClient(new WebViewClient() {           
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (url.equals("theURLYouDontWantToLoadInBrowser")) { 
            //Do your thing 
            startActivity(new Intent(this, OnlineQuery.class));
            return true;
        } else { 
            return false;          
        }       
    });
