在Android上的WebView中阻止URL [英] Block a URL in a WebView on Android

问题描述

我想阻止链接加载到Webview中.

I want to block a link from loading within a Webview.

代码

public class WebMy extends Activity {


   
    private WebView mWebview;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
            setContentView(R.layout.pantalla);
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);  
            
    
             
            mWebview  = new WebView(this);
            mWebview.setWebViewClient(new WebViewClient()); 
            mWebview.getSettings().setJavaScriptEnabled(true); // Enable JavaScript.

            mWebview .loadUrl("http://www.myweb.com");
            setContentView(mWebview );
           
    }

潜在的解决方案

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) {
        if (Uri.parse(url).getHost().equals("www.google.com")) {
             // This is my web site, so do not override; let my WebView load the page.
             return false;
        }

        // Reject everything else.
        return true;
    }
}

我不知道我该如何在代码中使用它.例如，如果我要阻止此URL http://www.myweb.com/pepito .如何使用此代码执行此操作?谢谢.

I don´t know how I have to use this in my code. For example, if I want to block this url http://www.myweb.com/pepito. How can I do this with this code? Thank you.

推荐答案

shouldOverrideUrlLoading will examine the web page URL loaded into the WebView and all URLs loaded within the page content.

public class MyWebViewClient extends WebViewClient {
    public boolean shouldOverrideKeyEvent (WebView view, KeyEvent event) {
         
         return true;
    }

    public boolean shouldOverrideUrlLoading (WebView view, String url) {
        if (Uri.parse(url).getHost().equals("http://www.myweb.com/pepito")) {
             // This is my web site, so do not override; let the WebView load the page.
             return false;
        }

        // Reject everything else.
        return true;
    }
}
