please see you are using arraylist in constructor

public MyAdapter(Context context, int textViewResourceId,   ArrayList<String> hltagList) {
            super(context, textViewResourceId, hltagList);
}

whereas accessing its elements via array. just change your line to 

label.setText(hltag_List.get(position));

Change your adapter code to following if, you have an array in datasource:

public MyAdapter(Context context, int textViewResourceId,   String[] hltagList) {
            super(context, textViewResourceId, hltagList);
        }

and keep the line:

label.setText(hltag_List[position]);

I think you should use ArrayList.get(int index) to obtain the i-th object in the list.

If it is a Arraylist , use hltag_List.get(position) . 

label.setText(hltag_List.get(position));
