我有一个简单的 helloworld 应用程序。我试图告诉 Activity 用户点击了“Cnn.com”
WebViewClient wc = new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equals("http://cnn.com/")) {
//TELL ACTIVITY CNN WAS CLICKED
return true;
} else {
return false;
}
}
};
mWebView.setWebViewClient(wc);
我该怎么做。
(我来自 C# .NET 背景)
最佳答案
public class YourActivity extends Activity{
// bla bla bla
// the code you already have
WebViewClient wc = new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equals("http://cnn.com/")) {
YourActivity.this.tellMe();
return true;
} else {
return false;
}
}
};
// this is the method to 'tell' the activity that someone clicked the link
public void tellMe(){
// in this case I just raise a toast.
// but you can do whatever you want here ;)
Toast.makeText(YourActivity.this, "eyy!! somebody clicked the cnn link", 1).show();
}
}
