Thanks to a clever colleague here who suggested this. Since sub-activities inherit any android:screenOrientation set on their launching parent in the manifest, if you lock the parent one way but want the user to be able to control the orientation of the child, you need an explicit constant for that. Lo! and behold! ActivityInfo has one, "user" -- so:
android:screenOrientation="user" So "portrait," "landscape," "user," and "sensor" give pretty good control I also see "nosensor" -- which I assume you need if you have previously set a parent to "sensor." ? or? Finally, there is "behind" -- does anyone know what a "behind orientation" would be" ? -- Ward ==================== Okay, I think I know the answer as to what can cause an activity not to rotate. Every activity I wanted to rotate was started with startActivityForResult() (i.e. it was a sub-activity). It appears sub-activities "inherit" the "android:screenOrientation" of their parent in the manifest. In my case, I have portrait main screens, launching landscape sub-activities that contain forms for keyboard entry. If I set android:screenOrientation="portrait" on the main screen, the sub-activities will not rotate, unless I _explicitly_ add android:screenOrientation="landscape" to them. Which is fine, except they start out rotated, which is not necessarily what a user expects. I suppose I could launch my data entry screens as first-class activities (using startActivity() instead of startActivityForResult()) and pass the results back out-of-band and manually restart the parent, but it sure isn't as pretty as using the built-in result machinery. (Or, yes, I could become more "one" with Android and do two sets of layouts and put the user in absolute control, but that's a lot of work and I am so very lazy...) -- Ward ==================== Hello All: I asked this before and did not get an answer, so let me try again, simpler: On the G1... What can cause an activity to NOT rotate to landscape when the phone is opened? (I want it to rotate.) No android:screenOrientation is set, and the activity is destroyed and recreated, but the new layout is still portrait.
