您可以通过为webview使用自定义WebViewClient来拦截url单击。
1)为WebView设置自定义WebView客户端
2)重写下面的方法并返回true（你也可以根据特定的url来做这件事）

shouldOverrideUrlLoading(WebView view, WebResourceRequest request)

3)重写下面的方法并处理单击并使用包名称或playstore url启动活动。
public void onLoadResource（WebView view，String url）

WebView mWebView; 


WebViewClient customWebClient = new WebViewClient(){
    
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request){
//This can be modified based on the url . URL can be retrieved using request.getUrl()
        return true;
    }
    
    @Override
    public void onLoadResource(WebView  view, String  url){
        if( url.equals("") ){
            // launch playstore activity
              final String appPackageName = "package name of the application"
              try {
                startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
                  } catch (android.content.ActivityNotFoundException anfe) {
                        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
                  }
        }
    }
}
mWebView.setWebViewClient(customWebClient);

在WebViewClient重写方法shouldOverrideUrlLoading（）中

override fun shouldOverrideUrlLoading(view: WebView, request: WebResourceRequest): Boolean {
                val url = request.url.toString()                  

                // start intent with URIs that contain all patterns that you need
                if (url.contains("needed-pattern") {
                    try {
                        ContextCompat.startActivity(
                            view.context,
                            Intent(Intent.ACTION_VIEW, Uri.parse(url)),
                            null
                        )
                    } catch (e: ActivityNotFoundException) {
                        Log.d("Clicked app is not installed!")
                    }

                    return true
                }

                return false
            }
