How To Get Time In Slot Type In Android

I am trying to get time in slot type. for example bike shop is open 9am to 9pm so we can get the bike in that time. if anyone books a bike in evening 5 pm to 7 pm slot then it shou

Solution 1:

A model class to hold data

classTimeSlot{
String time;
boolean isAvailable;
} 

Custom adapter to change content of gridview

publicclassCustomListAdapterextendsBaseAdapter {
    private  ArrayList<TimeSlot> list;

    private LayoutInflater mInflater;
    Context con;

    publicCustomListAdapter(Context context, ArrayList<TimeSlot> list) {
        this.list = list;
this.con = context;
        mInflater = LayoutInflater.from(context);
    }

    publicintgetCount() {
        return list.size();        
    }

    public Object getItem(int position) {
        return list.get(position);
    }

    publiclonggetItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) 
    {
        convertView = new TextView(con);
//set layout params or inflate xml layout
        convertView.setText(list.get(position).time);
        convertView.setEnabled(list.get(position).isAvailable);
        return convertView;
    }
}

Main activity

    List<TimeSolt> slots ;
    //assign the data from network or local...//create gridview from xml ...

    gridView.setColumnCount(3);

    //other properties goes here..//create custom adapter

    adapter = newCustomAdapter(this, slots);

    //other properties like onitemclick....



gridView.setAdapter(adapter);

            //create gridview from xml ...
        calendarView.setOnDateChangeListener(newCalendarView.OnDateChangeListener() {
                    @OverridepublicvoidonSelectedDayChange(@NonNull CalendarView calendarView, int year, int month, int date) {
        //change the data of slots  according to date //slots = newData; and call 
    adapter.notifyDataSetChanged();

                    }
                });
