机器人的WebView - 截点击 [英] Android WebView - Intercept clicks

问题描述

我写了一个简单的HelloWorld应用与web视图具有一个simple.html网页在我的资产文件夹链接到CNN。

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>

如何在我的活动我抓住这个点击，从航行，然后告知http://CNN.com点击的活动停止的WebView？

How, in my Activity do I capture the click on this, stop the WebView from navigating, and then informing the Activity that "http://CNN.com" was clicked?

推荐答案

然后，你必须设置一个<一个href="http://developer.android.com/reference/android/webkit/WebViewClient.html"><$c$c>WebViewClient你的的WebView 并重写<一href="http://developer.android.com/reference/android/webkit/WebViewClient.html#shouldOverrideUrlLoading%28android.webkit.WebView,%20java.lang.String%29"><$c$c>shouldOverrideUrlLoading和<一href="http://developer.android.com/reference/android/webkit/WebViewClient.html#onLoadResource%28android.webkit.WebView,%20java.lang.String%29"><$c$c>onLoadResource的方法。让我给你举一个简单的例子：

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
        }
    }
}
