Answer 1

I would suggest to read the Android fundamentals article (especially the ActivatingComponents section).

A menu should start a new activity. If you want to change the content of one activity I would recommend to use tabs (TabActivity).

So here’s what to do (or at least what I suggest):

Create a new activity (e.g. MyTaskActivity). Add it to your AndroidManifest.xml in the application tag:

<activity android:name="your.pacakge.MyTaskActivity" />

And call this in onOptionsItemSelected:

startActivity(new Intent(this, MyTaskActivity.class));
