Android WebView - 拦截点击 [英] Android WebView - Intercept clicks

问题描述

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.

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.

<a href="http://cnn.com">cnn.com</a>

如何在我的 Activity 上捕获对此的点击，停止 WebView 导航，然后通知 Activity "http://CNN.com"被点击?

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?

推荐答案

那你就得设置一个 WebViewClient 到您的 WebView 并覆盖 shouldOverrideUrlLoading 和 onLoadResource 方法.举个简单的例子:

Then you have to set a WebViewClient to your WebView and override shouldOverrideUrlLoading and onLoadResource methods. Let me give you a simple example:

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
        }
    }
}
