Android WebView - Intercept clicks
提问by Ian Vink
I have written a simple helloworld app with a WebView which has a link to CNN on a simple.html page in my asset folder.
我编写了一个带有 WebView 的简单 helloworld 应用程序，该应用程序在我的资产文件夹中的 simple.html 页面上有一个指向 CNN 的链接。
<a href="http://cnn.com">cnn.com</a>
How can I capture the click on this on my Activity, stop the WebView from navigating, and then inform the Activity that "http://CNN.com" was clicked?
如何在我的 Activity 上捕获对此的点击，停止 WebView 导航，然后通知 Activity已单击“ http://CNN.com”？

Then you have to set a WebViewClientto your WebViewand override shouldOverrideUrlLoadingand onLoadResourcemethods. Let me give you a simple example:
然后你必须为WebViewClient你的WebView和覆盖shouldOverrideUrlLoading和onLoadResource方法设置一个。我给你举个简单的例子：
WebView yourWebView; // initialize it as always...
// this is the funny part:
yourWebView.setWebViewClient(yourWebClient);
// somewhere on your code...
WebViewClient yourWebClient = new WebViewClient(){
// you tell the webclient you want to catch when a url is about to load
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
return true;
}
// here you execute an action when the URL you want is about to load
@Override
public void onLoadResource(WebView view, String url){
if( url.equals("http://cnn.com") ){
// do whatever you want
}
}
}
