您应该重写shouldOverrideUrlLoading（）方法。该方法已被弃用，因此也请覆盖新方法。

inner class MyWebViewClient : WebViewClient()
{
    override fun shouldOverrideUrlLoading(view: WebView?, url: String?): Boolean
    {
        if(URLUtil.isNetworkUrl(url))
        {
            return false
        }
            try
            {
            val shareIntent= Intent()
            shareIntent.action=Intent.ACTION_VIEW
            shareIntent.data= Uri.parse(url)
            startActivity(shareIntent)
            }
            catch(e: ActivityNotFoundException)
            {Toast.makeText(this@MainActivity, "Appropriate app not found", Toast.LENGTH_LONG).show()
                Log.e("AndroidRide",e.toString())
            }
        return true
    }
    @RequiresApi(Build.VERSION_CODES.N)
    override fun shouldOverrideUrlLoading(view: WebView?, request: WebResourceRequest?): Boolean
    {
        val url=request?.url.toString()
        if(URLUtil.isNetworkUrl(url))
        {
            return false
        }
        try
        {
            val shareIntent= Intent()
            shareIntent.action=Intent.ACTION_VIEW
            shareIntent.data= Uri.parse(url)
            startActivity(shareIntent)
        }            catch(e: ActivityNotFoundException)
        {Toast.makeText(this@MainActivity, "Appropriate app not found", Toast.LENGTH_LONG).show()
            Log.e("AndroidRide",e.toString())
        }
        return true

    }
