android：为什么我的 webView 不显示任何内容并自动将我重定向到内置浏览器？

class ShowJob : DialogFragment(), View.OnClickListener {     var listPosition: Int? = 0     var offset: Int? = 0     lateinit var link: String     val TAG = ShowJob::class.java.simpleName!!     override fun onCreate(savedInstanceState: Bundle?) {         super.onCreate(savedInstanceState)         val bundle = arguments         offset = bundle!!.getInt("jobOffset")         link = bundle.getString("link")         listPosition = bundle.getInt("listPosition", 0)     }     override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {         val view = inflater.inflate(R.layout.show_job_scr,container,false)         val webView = view.findViewById(R.id.webView)         webView.loadUrl(link)         webView.webViewClient = HelloWebViewClient()         WebView.setWebContentsDebuggingEnabled(false)         return view     }     private inner class HelloWebViewClient : WebViewClient() {         override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {             val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))             startActivity(intent)             return true         }     }     override fun onClick(p0: View?) {     } }
