Android App crash because of Null Pointer exception on setting onClick listener in Editor class

I have created a Linear Layout onclick of a button which has an edit text. While typing there is a popup window for suggestions that comes up and the app crashes.

Stack trace:

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.setOnClickListener(android.view.View$OnClickListener)' on a null object reference

I found some related answers which stated that this happens on using Android PopupWindow class since the suggestions are using a PopupWindow as well. My code does not use PopupWindow as well.

This crash is happening mostly on Samsung Note 5, and Galaxy S6.

Any help would be appreciated!
