Android Kotlin：片段中包含Intent的OnClickListener

我一直试图在NewsFragment.kt下创建3 setOnClickListener（for US_Fragment.kt / EMEA_Fragment.kt / ASIA_Fragment.kt），但是卡住了。

如何在片段下创建setOnClickListener，以便如果单击按钮，程序将跳至其对应的页面？

非常感谢你。

代码如下：

NewsFragment.kt

class NewsFragment : Fragment() {
    // TODO: Rename and change types of parameters
    private var param1: String? = null
    private var param2: String? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        arguments?.let {
            param1 = it.getString(ARG_PARAM1)
            param2 = it.getString(ARG_PARAM2)
        }
    }

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {

        //Here is where I want to create 3 setOnClickListener with intent

    }

    companion object {

        @JvmStatic
        fun newInstance(param1: String, param2: String) =
            NewsFragment().apply {
                arguments = Bundle().apply {
                    putString(ARG_PARAM1, param1)
                    putString(ARG_PARAM2, param2)
                }
            }
    }


}

US_Fragment.kt

class US_Fragment : Fragment() {
 // TODO: Rename and change types of parameters
    private var param1: String? = null
    private var param2: String? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        arguments?.let {
            param1 = it.getString(ARG_PARAM1)
            param2 = it.getString(ARG_PARAM2)
        }
    }

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        val view = inflater.inflate(R.layout.fragment_us, container, false)
        view.usnews.layoutManager = LinearLayoutManager(activity)
        view.usnews.adapter = MainAdapter()

        return view
    }

    companion object {
        @JvmStatic
        fun newInstance(param1: String, param2: String) =
            US_Fragment().apply {
                arguments = Bundle().apply {
                    putString(ARG_PARAM1, param1)
                    putString(ARG_PARAM2, param2)
                }
            }
    }
}

EMEA_Fragment.kt

class EMEA_Fragment : Fragment() {
    // TODO: Rename and change types of parameters
    private var param1: String? = null
    private var param2: String? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        arguments?.let {
            param1 = it.getString(ARG_PARAM1)
            param2 = it.getString(ARG_PARAM2)
        }
    }

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        val view = inflater.inflate(R.layout.fragment_emea, container, false)
        view.emeanews.layoutManager = LinearLayoutManager(activity)
        view.emeanews.adapter = MainAdapter()

        return view
    }

    companion object {
        @JvmStatic
        fun newInstance(param1: String, param2: String) =
            EMEA_Fragment().apply {
                arguments = Bundle().apply {
                    putString(ARG_PARAM1, param1)
                    putString(ARG_PARAM2, param2)
                }
            }
    }
}

ASIA_Fragment.kt

class ASIA_Fragment : Fragment() {
    // TODO: Rename and change types of parameters
    private var param1: String? = null
    private var param2: String? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        arguments?.let {
            param1 = it.getString(ARG_PARAM1)
            param2 = it.getString(ARG_PARAM2)
        }
    }

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        val view = inflater.inflate(R.layout.fragment_asia, container, false)
        view.asianews.layoutManager = LinearLayoutManager(activity)
        view.asianews.adapter = MainAdapter()

        return view
    }

    companion object {

        fun newInstance(param1: String, param2: String) =
            ASIA_Fragment().apply {
                arguments = Bundle().apply {
                    putString(ARG_PARAM1, param1)
                    putString(ARG_PARAM2, param2)
                }
            }
    }
