Activity.startSubActivity() would have been the way to go, but has
been removed with SDK 0.9. Here is how I worked around this problem:
Unfortunately, any start of an activity (i.e. using
Activity.startActivity(), Activity.startActivityForResult()) from
within a "parent" activity calls the "parent's" onStop() method. This
means the end of the "parent" activity, unless Activity.onStop() is
not overridden to catch that call.
Sp every time before I call Activity.startActivity() in the "parent"
activity, I set a flag menuItemSelected. which the overridden onStop()
evaluates to circumvent the termination of the "parent" activity. I
have no visibility how the app state transitions play together with
the various state change functions, but the following resulted in the
desired behavior (i.e. keeps the "parent" activity alive):
--------------- snip ------------------
@Override
protected void onStop() {
super.onStop();
if (!menuItemSelected) {
this.finish();
}
menuItemSelected = false;
}
--------------- snip ------------------
I am not sure if this is the right way to do it, but could not
identify another solution.
Hope this helps, JP
