    text
    copied!<p>I wish to have a single class which all of my <code>Activity</code> classes extend. I have <code>ListActivities</code>, <code>Activities</code>, <code>MapActivities</code>, <code>TabActivities</code>, etc in my App.</p> <p>I have many of these different activities in my app, ~12 activities. I want each of them to have the methods which are in the parent class.</p> <p>Right now, i have created 4 parent activity classes which are extended from a certain activity depending on their type(<code>ListActivity</code>, <code>Activity</code>, <code>MapActivity</code>, <code>TabActivity</code>)</p> <p>I am creating a lot of redundant code - each of the 4 parent activities has almost identical code, in exception for what class activity it extends.</p> <p>Here is an example that may clarify what my problem is:</p> <ul> <li>I have an <code>Activity</code>: <code>MenuScreen</code> which extends <code>BaseListActivity</code> </li> <li><code>BaseListActivity</code> extends <code>ListActivity</code></li> <li><p><code>BaseListActivity</code> contains methods and fields which i want all my activities to have access to</p></li> <li><p>I have another <code>Activity</code>: <code>HomeScreen</code> which extends <code>BaseActivity</code></p></li> <li><code>BaseActivity</code> extends <code>Activity</code></li> <li><code>BaseActivity</code> contains the same methods and fields which are in my other <code>Base[&lt;type&gt;]Activity</code> classes(such as <code>BaseListActivity</code>)</li> </ul> <p>these methods/fields are copy-pasted to all my <code>Base[&lt;type&gt;]Activity</code>, and seems awfully redundant to me.</p> <p>Can i create a master activity class which all types of Activity classes can use as its parent? if not, am i stuck with copy and pasting this code and feeling gross/dirty about it?</p>
