WebView链接点击打开默认浏览器

发布于 2024-10-03 19:07:38 字数 163 浏览 0 评论 0原文

现在我有一个加载网络视图的应用程序,并且所有点击都保存在应用程序内。我想做的是当某个链接(例如 http://www.google.com)在应用程序中单击它会打开默认浏览器。如果有人有任何想法,请告诉我!

Right now I have an app that loads a webview and all the clicks are kept within the app. What I would like to do is when a certain link, for example, http://www.google.com is clicked within the app it opens the default browser. If anyone has some ideas please let me know!

我今天必须做同样的事情,并且我在 StackOverflow 上找到了一个非常有用的答案,我想在这里分享,以防其他人需要它。

来源(来自sven

webView.setWebViewClient(new WebViewClient(){
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (url != null && (url.startsWith("http://") || url.startsWith("https://"))) {
            view.getContext().startActivity(
                new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
            return true;
        } else {
            return false;
        }
    }
});

I had to do the same thing today and I have found a very useful answer on StackOverflow that I want to share here in case someone else needs it.

webView.setWebViewClient(new WebViewClient(){
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (url != null && (url.startsWith("http://") || url.startsWith("https://"))) {
            view.getContext().startActivity(
                new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
            return true;
        } else {
            return false;
        }
    }
});

WebView webview = (WebView) findViewById(R.id.webview);
webview.loadUrl(https://whatoplay.com/);

您不必包含此代码。

// webview.setWebViewClient(new WebViewClient());

而是使用下面的代码。

webview.setWebViewClient(new WebViewClient()
{
  public boolean shouldOverrideUrlLoading(WebView view, String url)
  {
    String url2="https://whatoplay.com/";
     // all links  with in ur site will be open inside the webview 
     //links that start ur domain example(http://www.example.com/)
    if (url != null && url.startsWith(url2)){
      return false;
    } 
     // all links that points outside the site will be open in a normal android browser
    else
    {
      view.getContext().startActivity(
      new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
      return true;
    }
  }
});
WebView webview = (WebView) findViewById(R.id.webview);
webview.loadUrl(https://whatoplay.com/);

You don't have to include this code.

// webview.setWebViewClient(new WebViewClient());

Instead use below code.

webview.setWebViewClient(new WebViewClient()
{
  public boolean shouldOverrideUrlLoading(WebView view, String url)
  {
    String url2="https://whatoplay.com/";
     // all links  with in ur site will be open inside the webview 
     //links that start ur domain example(http://www.example.com/)
    if (url != null && url.startsWith(url2)){
      return false;
    } 
     // all links that points outside the site will be open in a normal android browser
    else
    {
      view.getContext().startActivity(
      new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
      return true;
    }
  }
});

您只需要添加以下行

yourWebViewName.setWebViewClient(new WebViewClient());

即可查看this以获取官方文档。

You only need to add the following line

yourWebViewName.setWebViewClient(new WebViewClient());

Check this for official documentation.

你可以使用 Intent 来实现这一点:

Intent browserIntent = new Intent("android.intent.action.VIEW", Uri.parse("your Url"));
startActivity(browserIntent);

you can use Intent for this:

Intent browserIntent = new Intent("android.intent.action.VIEW", Uri.parse("your Url"));
startActivity(browserIntent);

您可以为此使用 Intent:

Uri uriUrl = Uri.parse("http://www.google.com/"); 
Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);  
startActivity(launchBrowser);  

You can use an Intent for this:

Uri uriUrl = Uri.parse("http://www.google.com/"); 
Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);  
startActivity(launchBrowser);

由于这是有关 WebView 中外部重定向的首要问题之一,因此这里有一个 Kotlin 上的“现代”解决方案:

webView.webViewClient = object : WebViewClient() {
        override fun shouldOverrideUrlLoading(
            view: WebView?,
            request: WebResourceRequest?
        ): Boolean {
            val url = request?.url ?: return false
            //you can do checks here e.g. url.host equals to target one
            startActivity(Intent(Intent.ACTION_VIEW, url))
            return true
        }
    }

As this is one of the top questions about external redirect in WebView, here is a "modern" solution on Kotlin:

webView.webViewClient = object : WebViewClient() {
        override fun shouldOverrideUrlLoading(
            view: WebView?,
            request: WebResourceRequest?
        ): Boolean {
            val url = request?.url ?: return false
            //you can do checks here e.g. url.host equals to target one
            startActivity(Intent(Intent.ACTION_VIEW, url))
            return true
        }
    }

现在,public boolean shouldOverrideUrlLoading(WebView view, String url) 已被弃用,并使用 public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request),您可以在Java:

private class MyWebViewClient extends WebViewClient {
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            if (Objects.equals(request.getUrl().toString(), "http://www.google.com/")) {
                Uri uri = request.getUrl();
                startActivity(new Intent(Intent.ACTION_VIEW, uri));
                return true;
            }
            else {
                return false;
            }
        }
    }

只需将 http://www.google.com/ 替换为您要在网络中打开的网址浏览器而不是网页视图。

Now that public boolean shouldOverrideUrlLoading(WebView view, String url) is deprecated and public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) is used instead, you can use the following code in Java:

private class MyWebViewClient extends WebViewClient {
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            if (Objects.equals(request.getUrl().toString(), "http://www.google.com/")) {
                Uri uri = request.getUrl();
                startActivity(new Intent(Intent.ACTION_VIEW, uri));
                return true;
            }
            else {
                return false;
            }
        }
    }

Just replace http://www.google.com/ with the URL you want to open in web browser instead of webview.
