未解决的引用:将java转换为kotlin时的setText

Question

我想使用Android将安卓应用程序的演示从java转换为kotlin。但我犯了一些错误。

一些Java代码是：

   public static class FileServerAsyncTask extends AsyncTask<Void, Void, String> {
    private boolean isname=true;
    private String name="啦啦啦";
    private Context context;
    private TextView statusText;
    Handler myhandler=new Handler(){
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what){
                case 10:
                    statusText.setText("XXXXX");
            }
        }
    };

    /**
     * @param context
     * @param statusText
     */
    public FileServerAsyncTask(Context context, View statusText) {
        this.context = context;
        this.statusText = (TextView) statusText;
    }

Studio将它们转换为

 class FileServerAsyncTask
    /**
     * @param context
     * *
     * @param statusText
     */
    (private val context: Context, statusText: View) : AsyncTask<Void, Void, String>() {
        private val isname = true
        private var name = "啦啦啦"
        private var statusText: TextView

        init {
            this.statusText = statusText as TextView
        }

        internal var myhandler = object : Handler() {
            override fun handleMessage(msg: Message) {
                when (msg.what) {
                    10 -> statusText.setText("XXXXX")
                    else -> {

                    }
                }
            }
        }

但是在10 -> statusText.setText("XXXXX")上也有错误

我将其更改为10 -> statusText.text = "XXXX"，但错误仍然存在。然而，在同一文件中的其他句子是可以的。

怎么了？

(private val context: Context, statusText: TextView) : AsyncTask<Void, Void, String>() {
    private val isname = true
    private val name = "啦啦啦"
    private val statusText: TextView
    internal var myhandler: Handler = object : Handler() {
        override fun handleMessage(msg: Message) {
            when (msg.what) {
                10 -> statusText.text = "XXXXXX"
            }
        }
    }

    init {
        this.statusText = statusText as TextView
    }

    override fun doInBackground(vararg params: Void): String? {
        return null
    }
}

问题是构造函数将视图更改为textview。
