Я пытаюсь запустить подробные действия при выборе карты в режиме просмотра ресайклеров. Я использую интерфейс и прослушиватель кликов, чтобы отправить клик на фрагмент, но при касании карты ничего не происходит.Карты в recyclerView не доступны для просмотра
Мой адаптер выглядит так ...
пакет com.garciaericn.t2d.data;
public class DeviceAdapter extends RecyclerView.Adapter<DeviceAdapter.MyViewHolder> {
private LayoutInflater inflater;
private Context context;
private ClickListener clickListener;
List<Device> data = Collections.emptyList();
public DeviceAdapter(Context context, List<Device> data) {
inflater = LayoutInflater.from(context);
this.context = context;
this.data = data;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = inflater.inflate(R.layout.card_layout, parent, false);
MyViewHolder holder = new MyViewHolder(view);
return holder;
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Device device = data.get(position);
String batteryLevelString = String.valueOf(device.getBatteryLevel()) + "%";
holder.deviceNameTV.setText(device.getDeviceName());
holder.batteryLevelTV.setText(batteryLevelString);
if (device.isCharging()) {
holder.isChargingTV.setText("Is charging");
} else {
holder.isChargingTV.setVisibility(View.GONE);
}
}
@Override
public int getItemCount() {
return data.size();
}
class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
// Temp data set
private String[] mDataset;
TextView deviceNameTV;
TextView batteryLevelTV;
TextView isChargingTV;
public MyViewHolder(View itemView) {
super(itemView);
deviceNameTV = (TextView) itemView.findViewById(R.id.device_name_tv);
batteryLevelTV = (TextView) itemView.findViewById(R.id.battery_level_tv);
isChargingTV = (TextView) itemView.findViewById(R.id.isChargingTV);
}
@Override
public void onClick(View view) {
if (clickListener != null) {
clickListener.deviceSelected(view, getPosition());
}
}
}
public void setClickListener(ClickListener clickListener) {
this.clickListener = clickListener;
}
public interface ClickListener {
public void deviceSelected(View view, int position);
}
}
И мои фрагменты, как это ...

public class DevicesCardViewFragment extends Fragment implements DeviceAdapter.ClickListener {
private static final String LOGTAG = "DevicesCardViewFragment";
private OnFragmentInteractionListener mListener;

}

// Bundle parameters is necessary
return new DevicesCardViewFragment();
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
settings = PreferenceManager.getDefaultSharedPreferences(getActivity());
mBatteryHelper = new BatteryHelper(getActivity());
// Update stats of current device.

Toast.makeText(getActivity(), "Battery level: " + mBatteryHelper.getCurrentBatteryLevel() + "%", Toast.LENGTH_LONG).show();
// Update device stats
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_devices_list, container, false);
mListener.showAd();
// Obtain recycler view
mRecyclerView = (RecyclerView) view.findViewById(R.id.devices_recycler_view);
