I am working on an Android (v3.0) application that has a requirement of mimicking the weekly calendar layout found on Google Calendar:

The events will be based on external requests through the Google Calendar API (I already have this part working). Using the API, I can obtain a list of events for the week, with each event having a starting and and ending datetime. I would like to use this data to show the scheduled events to the application's users in a view similar to the one above.

Here's what I have so far:

The XML appears below:

<?xml version="1.0" encoding="utf-8"?>

            </LinearLayout>
        </RelativeLayout>
    </ScrollView>

</LinearLayout>

My approach was to make 40dp equal to 1 hr of time. Thus, whenever I would like to add an event that has a duration of 1.5 hours, I will make an 60dp button that I will place at the exact location that the time begins (12am = 0dp from the top, 1pm = 40dp from the top, 2pm = 80d from the top, etc).

My questions are:

1. Is there a better way of doing this?
2. How can I convert my XML to be stand-alone view that could be added to any Android project? (I plan on perhaps making a blog post about the end product)

Thank you!
