How to remove the last item in recyclerview adapter by a button?

I have a recyclerview and I want to delete the last item on it when I click a button that is not in the recyclerview. I want to delete the item and notify the adapter that the item is deleted so I can enter another item. By the way, the items I enter are by edittext and a button.

public void setPersonName(Integer personName) {

}
public PersonUtils(Integer personName) {
this.personName = personName;
}
}
I expect to delete the last item (integer) in the recyclerview and notify the adapter so I can edit the value when needed.

You can add a method in your adapter to remove last item in the list:
public ViewHolder removeLastItem() {
if (personUtils == null || personUtils.isEmpty()) return;
personUtils.removeAt(personUtils.getSize()-1);
notifyDataSetChanged();
}
When the button is clicked, just call:
adapter.removeLastItem()

Check if you are in the last index, then remove the item and use notifyItemRemoved to notify any registered observers:
if(currentPosition == 0){
listOfItems.removeAt(currentPosition)
notifyItemRemoved(currentPosition)
}

When I apply OnItemClickListener it does not do any action like intent inside the func not called. I tried toast too but nothing shown on clicking the listView Items.
I also tried OnItemSlectedListener , it also not worked for me.
What is the problem here with this code. ?

Thanks Every One. Issue was with autolink on email and phone, I make their focusable=false but nothing happened.Then I remove it and guess what? Clicklistener also starts working.

The attribute android:clickable="true" in your ListView could be overriding all of click events of its child views, you should probably remove it:
<ListView
android:clickable="true" <!-- Remove this attribute -->
android:id="#+id/listView_emp_directory_xml"
android:layout_below="#id/relatice_layout_header_emp_directory_activity_xml"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

Facebook Native in feed ads are overlapping to each other in RecyclerView

I have an app which has Recyclerview and I want to put some facebook Native ads in between list items, like every 5 list items 1 native ad will be shown. everything is working perfectly but main problem is when I scroll down adChoice icon is being doubled and on scrolling up also adChoice icons are getting doubled. It seems that ads are overlapping to the previous one.
SCREENSHOT
Any suggestion will help me a lot. Here is the all source code and the official facebook audience network native ad code sample.

Ad are getting overlapped when adding in the container. The solution is to clear the container before adding the ads again.
For example:
AdChoicesView adChoicesView = new AdChoicesView(context, nativeAd, true);
// Clear the container.
adChoicesContainer.removeAllViews()
adChoicesContainer.addView(adChoicesView);

onItemClick not working for Card View

It uses retrofit 2.0 to fetch the data from the webservice and bind it to the card view. When I click on the card view having image and textviews, on click is not triggering, rather a strange behaviour is at the very corner edges of the card view onclick is triggering.

CustomerItemClickListner Interface to handle row item on click
package com.innovation.myapp.jwelleryonrent.model.adapter;
import android.view.View;
/**
*
*/
public interface CustomItemClickListner {
public void onItemClick(View v,int position);
}

First create one variable of your interface in your adapter:
CustomItemClickListener mListener;
then like you have set in your OnClick() method:
if (mListener != null) {
mListener.onItemClick(v, getAdapterPosition());
}
and the last thing you need to modify in your adapter is creating new method which you will call later in your activity class for handling listener:
public void setOnItemClickListener(CustomItemClickListener listener) {
mListener = listener;
}
now you can call this method in your activity like this:
adapter.setOnItemClickListener(this); // implement interface
// or
adapter.setOnItemClickListener(new CustomItemClickListener());
