I've tried to set up a click and toch listener for my RecyclerView with tutorials. But every tutorial I've tried I finaly failed because I've set the RecyclerView up with an other tutorial and all tutorials are looking different. Please can you help me detect click for each row? For example when a user clicks my first row (which is a logout field) it should logout the user from the app. All of my logout actions are working but the click on RecyclerView don't.
My SettingsAdapter:
import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v7.app.AlertDialog;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import android.widget.Toast;
import java.util.List;

public TextView settingTitle, settingSubtitle;
public MySettingHolder(View view) {
super(view);
settingImage = (ImageView) view.findViewById(R.id.settingImage);
settingTitle = (TextView) view.findViewById(R.id.settingTitle);
settingSubtitle = (TextView) view.findViewById(R.id.settingSubtitle);
}
}
public SettingsAdapter (List<Settings> settingList) {
this.settingList = settingList;

@Override
public MySettingHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.settings_list_row, parent, false);
return new MySettingHolder(itemView);
}
@Override
public void onBindViewHolder(MySettingHolder holder, int position) {
// Setting for one entry
Settings setting = settingList.get(position);
holder.settingImage.setImageResource(setting.getSettingImageUrl());
// If the settingSubtitle is empty it should be not visible and just the settingTitle
if (setting.getSettingSubtitle().equals("")) {
holder.settingTitle.setText(setting.getSettingTitle());
holder.settingSubtitle.setVisibility(View.GONE);
} else {
