Design of android activity
<p>Alice has to answer three questions. After she answered the questions she gets a dialog that lists the question and answers and there's a button to save the answers to a database.</p>

<p>At the moment I think that the design should be three classes: Master, Question, Summary.</p>

<p>Master calls Question with an intent that includes the question text of question 1.
After Alice inputs her answer the Question returns the answer to master via an intent.</p>

<p>Repeat two times.</p>

<p>Then Master does processing of the questions and calls Summary via an intent.</p>

<p>Is this kind of design recommendable in Android? Is it possible to have such an Master activity. If so, how can I allow a running master activity to listen to intents?</p>
