THE BEST PLACE FOR MAGENTO & ANDROID TIPS AND TRICKS… AND MUCH MORE! Sometimes is difficult to use kotlin android extensions, the best way to use Kotlin synthetic in Adapter or ViewHolder is like this: val tvTask = view.findViewById(R.id.tvTask) tvTask.text = task.description fun bind(task: Task, checkTask: (Task) -> Unit, delete*ask:  (Task) -> Unit) = with(itemView){ This android function notifies the attached observers that the underlying data has been changed and any View reflecting the data set You can use NOTIFYDATASETCHANGED ARRAYADAPTER, but it only works if you use the add(), insert(), remove(), and clear() on the Adapter. When an ArrayAdapter or BaseAdapter are constructed, it holds the reference for the List that was pas*ed in. If you were to pas* in a List that was a member of an Activity, and change that Activity member later, the ArrayAdapter is still holding a reference to the original List. The Adapter does not know you changed the List in the Activity. Use the functions of the ArrayAdapter to modify the underlying List (add(), insert(), remove(), clear(), etc.) Re-create the ArrayAdapter with the new List data. (Uses a lot of resources and garbage collection.) Create your own clas* derived from BaseAdapter and ListAdapter that allows changing of the underlying List data structure. Use the NOTIFYDATASETCHANGED() every time the list is updated. To call it on the UI-Thread, use the runOnUiThread() of Activity. Then, public clas* MultipleData {     private String text;     public MultipleData(String text, boolean selected) {         this.text = text;     public String getText() {         return text;     public void setText(String text) {         this.text = text;     public boolean isSelected() {         return selected;     public void setSelected(boolean selected) {         this.selected = selected;         android:checked=false         android:clickable=false
