未解决的参考：参数

Question

我不知道出于什么原因，我在构建项目时得到未解析的参考：参数。无法理解我做错了什么？有人能指出我哪里出错了？我正在使用支持片段android.support.v4.app.Fragment;

public class Tab1() : Fragment() {
    val TAG = "Tab1";
    companion object {
        public fun create(uuid: String): Tab1 {
            val history:Tab1 = Tab1()
            history.arguments.putString("uuid",uuid)
            return history
        }
    }

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup, savedInstanceState: Bundle?): View {
        val view = inflater.inflate(R.layout.tab1, container, false)
        return view
    }
}

是的！我通过以下实现解决了这个问题。感谢。

companion object Factory {
        public fun newInstance(uuid: String): Tab1 {
            val history:Tab1 = Tab1()
            val args = Bundle()
            args.putString("uuid",uuid)
            history.setArguments(args)
            return history
        }
    }
