I know that in XML, Views are expensive, and ideally you should strive for as little as possible. But in my case, I am designing my layout in a such a way that I am sort of forced to have a lot of Views, close to 80. Eclipse gave me a warning on this, so I deleted some Views, but I can only do so much as my implementation requires minimum, 48 Views off the bat, and not including some extra stuff. So my question is in whether I should really find a simpler way, or if its fine. What is the actual number that really should be maximum?

    </GridLayout>


</RelativeLayout>
</ScrollView>

I should probably explain the logic behind what the code translated to. I essentially needed a GridLayout of 24 rows, as well as another GridLayout of another 24 rows floated above it. I did this to separate what I need to float above the first GridLayout. Its suppose to be for a Day View for a calendar app.

As I said I would use a ListView to show the data to avoid making so much views. First I would create a class to represent the user events that you show in the list:

private static class Event {

        public int startHour;
        public int hours = 1;
        public String name;
        public String date;
        public boolean isEmptyEvent = true;

        public Event(int startHour, int hours, String name, String date,
                boolean isEmptyEvent) {
            this.startHour = startHour; 0 to 23 (the method getStartHour makes this pretty)
            this.hours = hours; // how many this event requires(default 1)
            this.name = name;
            this.date = date;
            this.isEmptyEvent = isEmptyEvent;
        }

        public String getStartHour() {
            // should optimize this method so you don't end up creating String
            // after String(char array?)!
            if (startHour < 10) {
                return "0" + startHour + ":00";
            }
            return String.valueOf(startHour) + ":00";
        }
    }

Then I would parse the data I have in Events object(I don’t know what you save in the database so this is just guessing):

public SparseArray<Event> getData(String date) {
        // here you get the data from the database and create Events object for
        // those dates
        SparseArray<Event> data = new SparseArray<Event>(); // for efficiency
                // add some random events
        data.put(3, new Event(3, 1, "Breackfast", date, false));// one event at 3 taking 1 hour
        data.put(14, new Event(14, 3, "Lunch", date, false));// one event at 14 taking 3 hour
        data.put(20, new Event(20, 2, "Dinner", date, false));// one event at 20 taking 2 hour
        return data;
    }

Then in the adapter I would fill the rest of the empty entries(where the user didn’t yet set anything) with empty Events objects and show it to the user. As the code is a little big I will not post it here , instead you can find the full activity+ layouts here https://gist.github.com/3370107
