我想阻止WebView中的网址，如何屏蔽网址？此代码不起作用。

Answer 1

如果您需要根据documentation的特定行为，则应返回true。

如果主机应用程序想要保留当前值，则返回true WebView并处理url本身，否则返回false。

Answer 2

阻止所有网址工作解决方案，即使我尝试过它。

public class MainActivity extends Activity {
private WebView wv1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    wv1 = new WebView(this);
    setContentView(wv1);
    wv1.getSettings().setLoadsImagesAutomatically(true);
    wv1.getSettings().setJavaScriptEnabled(true);
    wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
    wv1.loadUrl("http://www.kart.epizy.com");
    wv1.setWebViewClient(new MyWebViewClient());
    wv1.setClickable(true);
}

public class MyWebViewClient extends WebViewClient {
    public boolean shuldOverrideKeyEvent(WebView view, KeyEvent event) {
        // Do something with the event here
        return true;
    }

    public boolean shouldOverrideUrlLoading(WebView view, String url) {
     //return false to allow urls or add your condition like
       //return url.equals("https://play.google.com/store/apps/developer?id=kArt+Developers");
        return true;
    }
} }
