Question: i'm new to android developing and started to develop an booking app. There is a calendar view and i want to disable booked dates in that calendar. I found out that disabling feature is not there in android default calendar. so could you please help me to find a good custom calendar view that can disable specific dates. I need a resource or a library. Thank you!

Answer: 
Include CalendarPickerView in your layout XML.

```
<com.squareup.timessquare.CalendarPickerView
android:id="@+id/calendar_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

```

In the onCreate of your activity/dialog or the onCreateView of your fragment, initialize the view with a range of valid dates as well as the currently selected date.

```
Calendar nextYear = Calendar.getInstance();
nextYear.add(Calendar.YEAR, 1);

CalendarPickerView calendar = (CalendarPickerView) findViewById(R.id.calendar_view);
Date today = new Date();
calendar.init(today, nextYear.getTime()).withSelectedDate(today);

```

i have faced the same problem using custom calendar ,
i just overridden the function of adapter 

 @Override
    public boolean isEnabled(int position) {
         if(mySet.contains(position))
            return true;
        else
            return false;
    }

then i call the function int the adapter view 

 isEnabled(position);

befoer that tale Hashset and add the position which is displaying the calanderview 

           // mysetSize=set.size();
            //isEnabled(Integer.parseInt(gridvalue));
            Log.d(dayView.getTag()+"------1-------"+gridvalue,"-------"+position);
        } else if ((Integer.parseInt(gridvalue) < 7) && (position > 28)) {
            dayView.setTextColor(Color.WHITE);
            dayView.setClickable(false);
            dayView.setFocusable(false);
            Log.d("-------mySet------","-------"+mySet);
            Log.d(mysetSize+"-------28------"+gridvalue,"-------"+position);
            set.add(position);

        } else {
            // setting curent month's days in blue color.
            dayView.setTextColor(Color.DKGRAY);
            Log.d(dayView.getTag()+"-------current display post------","-------"+position);
            mySet.add(position);
        }

```
