我正在使用kotlin在android中使用芯片视图。我需要实现clickk功能

Question

就像按钮一样，我在每个芯片视图上使用了setOnClickListener。但它不起作用。如果这很容易回答，我很抱歉，但我是Android新手。所以请帮帮我。我的xml文件看起来很好。这是片段代码。

覆盖CreateView上的乐趣（膨胀器：LayoutInflater，容器：ViewGroup？，保存的InstanceState：Bundle？）：视图？{

     val view = inflater.inflate(R.layout.fragment_main, container, false)
     setHasOptionsMenu(true)
     byName = view.findViewById(R.id.byName)
     byPrice = view.findViewById(R.id.byPrice) if(Connection().checkConnectivity(activity as Context)) {

        no_net.visibility = View.GONE
        appbar.visibility = View.VISIBLE
        val q = Volley.newRequestQueue(activity as Context)
        val url = "http://13.235.250.119/v2/restaurants/fetch_result/"
        try{
            progress_bar.visibility = View.VISIBLE
            val jsonreq = object : JsonObjectRequest(
                Request.Method.GET,url,null,
                Response.Listener {
                    if(it.getJSONObject("data").getBoolean("success")){
                        list = arrayListOf<DataList>()
                        val data = it.getJSONObject("data").getJSONArray("data")

尝试使用以下代码，它将对您有所帮助。

      //activity xml
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<com.google.android.material.chip.Chip
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="UserName"
    android:id="@+id/userNameChip"/></LinearLayout>


 //Activity code
  class TestActivity : AppCompatActivity() {
private lateinit var userNameChip: Chip
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_test)
    userNameChip = findViewById(R.id.userNameChip)
    userNameChip.setOnClickListener { view ->
        val defaultUser: String = (view as Chip).text.toString()
        Toast.makeText(this,defaultUser,Toast.LENGTH_LONG).show()
    }
}
 }
