RecyclerView.ViewHolder no se vincula correctamente

Estoy construyendo una aplicación para Android usando java y kotlin. Soy muy nuevo en kotlin y estoy teniendo problemas con mi adaptador. por alguna razón, no parece que el adaptador ViewHolder esté vinculando correctamente. No estoy seguro de qué hacer ya que no recibo posts de error y tengo problemas para encontrar algo cuando estoy depurando. aquí está el código para mi adaptador:

data class NetworkTest(val addr: String, val port: String, val results: String, val protocol: String) public class NetTestRecyclerAdapter(val netList: List<NetworkTest>, val context: Context): RecyclerView.Adapter<NetTestRecyclerAdapter.NetTestRecyclerHolder>(){ override fun onBindViewHolder(holder: NetTestRecyclerHolder, position: Int) { holder.bindItems(netList[position]) } override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): NetTestRecyclerHolder { val v: View = LayoutInflater.from(context).inflate(R.layout.tested_list_item, parent, false) return NetTestRecyclerHolder(v) } override fun getItemCount(): Int { return netList.size } class NetTestRecyclerHolder(itemView: View): RecyclerView.ViewHolder(itemView){ fun bindItems(networkTest: NetworkTest){ val addrPortView = itemView.find<TextView>(R.id.addrPortView) val resultsProtocolView = itemView.find<TextView>(R.id.resultProtocolView) addrPortView.text = "Address: ${networkTest.addr} Port: ${networkTest.port}" resultsProtocolView.text = "Results: ${networkTest.results} Protocol: ${networkTest.protocol}" } } } 

y aquí está el código para mi actividad principal:

 public class NetTestActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { private RecyclerView mRecyclerView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_net_test); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); fab.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) .setAction("Action", null).show(); } }); DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); ActionBarDrawerToggle toggle = new ActionBarDrawerToggle( this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); drawer.setDrawerListener(toggle); toggle.syncState(); NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); navigationView.setNavigationItemSelectedListener(this); mRecyclerView = (RecyclerView)findViewById(R.id.networkList); List toolTestList = new ArrayList<>(); toolTestList.add(new NetworkTest("addr", "port", "results", "protocol")); NetTestRecyclerAdapter adapter = new NetTestRecyclerAdapter(toolTestList, getApplicationContext()); //context may need to be changed mRecyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext())); mRecyclerView.setAdapter(adapter); } @Override public void onBackPressed() { DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); if (drawer.isDrawerOpen(GravityCompat.START)) { drawer.closeDrawer(GravityCompat.START); } else { super.onBackPressed(); } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.net_test, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. int id = item.getItemId(); //noinspection SimplifiableIfStatement if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } @SuppressWarnings("StatementWithEmptyBody") @Override public boolean onNavigationItemSelected(MenuItem item) { // Handle navigation view item clicks here. int id = item.getItemId(); if (id == R.id.nav_camera) { // Handle the camera action } else if (id == R.id.nav_gallery) { } else if (id == R.id.nav_slideshow) { } DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); drawer.closeDrawer(GravityCompat.START); return true; } } 

por favor, ayúdame a encontrar lo que estoy haciendo mal aquí. gracias por adelantado por la ayuda.

aquí está mi file de layout para mi espectador, así como también

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/list_item" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/addrPortView" android:text="testing" android:layout_width="match_parent" android:layout_height="wrap_content"/> <TextView android:id="@+id/resultProtocolView" android:text="again" android:layout_width="match_parent" android:layout_height="wrap_content"/> </LinearLayout> 

mi layout de recyclerview se ve así:

 <?xml version="1.0" encoding="utf-8"?> <android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/networkList" android:layout_height="match_parent" android:layout_width="match_parent"> </android.support.v7.widget.RecyclerView> 

¿Debería include algo como esto?

 <include layout="@layout/activity_net_test" android:layout_width="match_parent" android:layout_height="match_parent"/> 

aquí está adb dumpsys top
