My getBindingAdapterrPosition only returns -1

I'm trying to implement a feature on my application, where - if you click on a RecyclerView item - it opens up a dialog box for that item with a picture - kind of like InstaGram.
However, I am trying to make an onClickListener, where I get the position of the adapter. The goal is, that it reads what item I click on, so it can open up a dialog box for that specific item. But no matter what item in the recyclerview I click on, it returns the position as being -1.
Here is my code for it:

I hope you all can help, as I have tried for a while, but continue to receive the same output no matter what I do.

You have to move your setOnClickListener from onCreateViewHolder into onBindViewHolder.
You might want to check this tutorial
Edit
Something like here:
#NonNull
#Override
public UserAdapter.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_list_item, parent, false);
final ViewHolder ViewHolder = new ViewHolder(view);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull UserAdapter.ViewHolder holder, int position) {
User user = userList.get(position);
holder.imageView.setImageResource(userList.get(position).getImage());
holder.textView.setText(userList.get(position).getTitle());
holder.item.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(mContext, "Test Click"+userList.get(position), Toast.LENGTH_SHORT).show();
}
});
}

Error in java file ,yosemiteadapter.java(ViewPageAdapter), making an tour app, app is crashing

I am making a tour app, it structure is like this:
First activity shows seasons like Summer, Winter, Spring, Autumn. After selecting any season, another activity pops up with locations around the world best suited for that season. After selecting any one location, another activity will pop up with 2 to 3 images with the description, and we will slide through these images. That's it. To make it more accessible, I tried adding this code to NawDrawer activity:

Originally the ViewPagerAdapter.java was for Hawaii (check the image), but I created exact same as Yoshimiteadapter.java for Yosemite, but it's not working.
I apologize for the inconvenience caused by the files :) ,it's messy ,but desperate help is needed:

I found the solution , it's related to this:
textView.setText(strings1[position]);
I have only one string, three images, which causes the error. [position] should be set to '0'; so the modification is like this:
textView.setText(strings1[0]);

list adapter using fragments

I am using a listAdapter to try to populate a listView. but i am having an issue and it is causing my application to crash. i initially wanted to populate the list into xml objects but i believe a listView would be better for my application..THIS IS MY ADAPTER
package com.example.victor.kidsrewards;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.view.LayoutInflater;
import android.widget.TextView;
import java.util.List;
/**
* Created by Victor on 3/20/2016.
*/
public class ListAdapter extends ArrayAdapter<Task> {
private final Context context;
private final List<Task> taskList;
public ListAdapter(Context context, List<Task> taskList){
super(context, R.layout.fragment_tasks, taskList);
this.context = context;
this.taskList= taskList;
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.fragment_tasks,parent,false);
/*TextView taskText = (TextView)rowView.findViewById(R.id.newTaskText);
taskText.setText(taskList.get(position).getText());
TextView pointsText = (TextView)rowView.findViewById(R.id.newPointsText);
pointsText.setText(taskList.get(position).getText());*/
return rowView;
}
}
**
**
this is my xml code
<!-- TODO: Update blank fragment layout -->
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#000"
android:text="TODO TEXT GOES_HERE">
</ListView>
</FrameLayout>
**

This is my fragment where i call my listadapter
package com.example.victor.kidsrewards;

import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.ListFragment;

import android.view.View;
import android.view.ViewGroup;
/**

public class TaskList extends ListFragment {
private TaskDataBase tdb;
public TaskList() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_task_list, container, false);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
tdb = new TaskDataBase(getContext());
setListAdapter(new ListAdapter(getContext(), tdb.getTasks()));
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
}
}

What is the name of the layout file that you have included?
If it is fragment_tasks.xml then fragment_tasks.xml should not have a ListView. It should at least have the textView with id newTaskText.
Define the content layout which contains a listView. Then there is a layout for each row. This should only contain the TextView (and other views relevant to a single row) but not ListView.

onPostExecute is not working in fragment activity

I want to load some data from a website using Jsoup in my fragment activity and show the output in the Textview. I am using AsyncTask to load the data from a website using Jsoup but after successfully getting the data from the website the onPostExecute method in AsyncTask is not displaying the data. I have tried to debug it and it seems like the there is a problem in onPostExecute

If you guys tell where the problem is or how to solve it, it will be very helpful to me

I don't think that your super class has an onPreExecute function, so
super.onPreExecute();
may be causing you some issues. You can try
super.onPostExecute();
That may be fix it.

Actionbarsherlock crashes on screen rotation using latest version

I'm wondering if anyone can help me. I'm pretty new to programming and this is a little over my head, but once this issue is resolved I think I can complete the rest of my program with my current skill set (I hope). Anyway, I'm using Actionbarsherlock to create a swipe tab interface. The code I used was found on Youtube as an example of how to do it. The URL to download the source is: https://www.dropbox.com/s/p91dzt4dekuia3q/SwipeyTabs.zip if anyone wants to look. The sourcecode is available for download, but I'll post what I believe are the relevant parts here. Basically, whenever the device (and emulator) is rotated, the app crashes. If I start the device in landscape mode, it works until rotated into portrait, and if I start in portrait it works until rotated into landscape. I get a null pointer exception as the error and could provide the logcat output if needed.
The MainActivity.java file is:
package com.rufflez.swipeytabs;

From what I could figure out, doing several hours of research, is that this used to be a bug in ABS that was addressed several versions ago and likely this issue is somehow connected to that issue. Any help would be very much appreciated. Especially if you can provide it in a teacher-student style so I can learn more effectively. :-) Thanks in advance to anyone attempting to help though!
