Android RecyclerView and custom Adapter position elements changes

I have a RecylcerView filled with a Custom Adapter recylerView.setAdapter(myAdapter), and the adaper is filled with different elements by an ArrayList. In the ViewHolder i overrided the
public void onBindViewHolder(#NonNull ViewHolder viewHolder, int position) method. In the custom ViewHolder i put a button. The button has a click listener on it. When i click the button i read the variable position and i am facing that the variable changes every time i click the same button.
Why this happens?
My Adapter is like this:

Seems that method getItemViewType is called after the click on LikePostButton so that : viewHolder.LikePostButton.setOnClickListener(v -> { gets an older currentPosition variable value
Thanks to everyone helping me to understand

you can override getItemViewType(position:Int) method and replace the line of super to return it with only position like this in Kotlin:
override fun getItemViewType(position: Int): Int {
return position
}
in Java :
#Override
public int getItemViewType(int position) {
return position;
}

Thanks, i solved it setting the listener on the button in the ViewHolder and then just calling getAbsoluteAdapterPosition() to get the correct position

How to increase Cart Count of action bar Textview from Recyclerview Adapter

Hi I have MainActivity which has ActionBar, and In Action Bar I Have CartIcon with textview. When i add from fragment i want to increase Textview of Action Bar. But i couldn't do this. Below is my code:

on Save Click i want to increase cart count but i couldn't able to do so far. please kindly suggest me what can i do to increase cart count from adapter
Here is a screenshot of my activity

Basic approach would be to make use of interface which is what you are doing.
Below just 2 changes in your code :
Implement interface in your Main Activity not in your Fragment.
Replace with below
recyleradpater = new RvAdapter(getContext(), lstOphthalmic,getActivity());
Will work for sure.

Changing Button image after response from server

Am working on an App in which implements a FOLLOW Button inside a View-pager.
when the user clicks the FOLLOW Button the button should change to FOLLOWING after getting success response from the server.
Although i have implemented it ...The button image doesn't change after the click.it has a very unusual behavior.
It sometimes shows FOLLOWING after the activity is reloaded or the pager slides.
Below is my code..

really appreciate any help.

Note, Fragments state on ViewPager are being initialize a Fragment before.
that is if three fragments A,B,C are use on ViewPager, B state is initialize on A while on user view, C also those the same when B is on user View.
There are two way to solve this
1) use A Fragment to implement the request method for response and set a public boolean to get response result true, then on B fragment where the button event is needed, check for boolean result.
2) In your AppController class check for result from A fragment and set to B fragment. This will always keep the result as it is even when the app is onPause.
check this http://www.androidhive.info/2014/05/android-working-with-volley-library-1/ for implementing AppController class.

In the xml that you have posted,replace the TAG <Fragment> with <LinearLayout> or <RelativeLayout> and inside this you simply show what you want to display in you UI
Make sure you extend Fragment class in you fragment activity

Could you post the code for your fragment? The problem could be with your import statements. You have 'import android.support.v4.app.FragmentActivity'. Do you have 'import android.support.v4.app.Fragment' in your fragment file?

Android ListView showing only first 4 items on repeat

I have a Fragment called User Management where I collect data from a server and display it in a ListView. It's also refreshable via SwipeRefreshLayout.
What happens is, if I get data on 1-4 users, it displays the data correctly. However, if I get data on more than 4 users, it displays the first 4 correctly, and instead of the fifth, it's the first one again, instead of the 6th, it's the second one and so on and so on.
I've tried everything I could think of, the adapter is getting the data correctly, the ListView is getting the adapter correctly, but for some reason, it peaks at 4 users displayed, and simply repeats them after that (the funny thing is, if I add a user and then refresh, it simply repeats the next user one more time in the list, so it's definitely aware of the change in user number)
Can you help me finding the problem?

Thank you!

There is a huge problem in your SampleAdapter.getView() method.
When you scroll down the View disappearing at the top of the screen is reused to be injected at the bottom. This reused View is the convertView you get as getView parameter.
As you code is, the reused view is injected with the exact same data (because if (convertView == null) { is always false when you scroll).
Images and texts are not updated.
When you scroll down, the element disappearing at the top just appears at the bottom, and so does others...
You should be doing something like:
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.row_usermana, null);
// The ViewHolder constructor should handle the mapping of its views
holder = new ViewHolder(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// Here you should only use holder as in:
holder.userpicture.setImageDrawable(getResources().getDrawable(getItem(position).userPicture));
...
}

This method looks strange, and is perhaps suspect. I don't see getUsers_mana() defined anywhere in this sample code, so I don't know if it is the problem or not. For one, you should call that 'UserManager.getInstance().getUsers_mana()' and then 'get(i)' once each and store the results in variables.
private void setContent(){
SampleAdapter adapter = new SampleAdapter(getActivity());
adapter.notifyDataSetChanged();
try {
if (!UserManager.getInstance().getUsers_mana().isEmpty()) {
for (int i = 0; i < UserManager.getInstance().getUsers_mana().size(); i++) {
Log.e("adding to adapter:",UserManager.getInstance().getUsers_mana().get(i).firstName + " " + UserManager.getInstance().getUsers_mana().get(i).lastName + "" + UserManager.getInstance().getUsers_mana().get(i).id + "" + UserManager.getInstance().getUsers_mana().get(i).username + "group:" + UserManager.getInstance().getUsers_mana().get(i).group);
adapter.add(new SampleItem(
UserManager.getInstance().getUsers_mana().get(i).id
, UserManager.getInstance().getUsers_mana().get(i).firstName + " " + UserManager.getInstance().getUsers_mana().get(i).lastName
, UserManager.getInstance().getUsers_mana().get(i).username
, UserManager.getInstance().getUsers_mana().get(i).group
, R.drawable.users_test
, R.drawable.settings
, R.drawable.delete
, UserManager.getInstance().getUsers_mana().get(i).activated
));
}
listView.setAdapter(adapter);Log.e("setting","ListView");
}
}catch (Exception e){
Log.e("error setContent", e.getMessage().toString());
}
}

It is because you are not doing anything in the
else {
convertView.getTag();
}
Check here
Why we should re-assign values for a recycled convertView in getView()
You have to reassign values to the convertView with the data of the 5th roq, 6th row etc. otherwise it still contains the old data

Remove the initialization of holder on the top and just put this line of code in the beginning of getView function.
ViewHolder holder = null;
You need to re initialize holder if its null and you need to update it with latest data if its not null.

See this sample it might help you
