[android-developers] Re: Force screen orientation and avoid destroy call

2009-08-28 Thread Derek 

Another question:
android:screenOrientation=portrait locks the screen orientation,
that's fine.
But it is possible to do the same in Activity source code ? (i.e.
removing the screenOrientation in AndroidManifest.xml).

I've tried the following code to keep the initial orientation but it
fails.

private int initialOrientation =
Configuration.ORIENTATION_UNDEFINED;

public void onCreate(Bundle savedInstanceState) {
initialOrientation = getResources().getConfiguration
().orientation;
...
}

public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
setRequestedOrientation(initialOrientation);
}

I've also tried with:
initialOrientation = getResources().getConfiguration().orientation;
initialOrientation = getRequestedOrientation();
initialOrientation = getWindow().getWindowManager().getDefaultDisplay
().getOrientation();


Thanks for the help.

 Well, I think it's the correct solution. But, then again, I'm biased in
 favor of the author of that fine, upstanding blog post.

Just call setRequestedOrientation().  onConfigurationChanged() is a really
bad place to do this though -- you'd typically do it in onCreate().

Note that the transition to your app will be much better if you can specify
the orientation in the manifest, since that way the system knows what
orientation to switch in to before it starts launching your app.

[android-developers] Re: Force screen orientation and avoid destroy call

2009-08-28 Thread Derek 

It seems that constants returned and expected are not the same between
ActivityInfo and Configuration.
Translating Configuration constants to ActivityInfo seems to solve the
problem:

 int orientation = getResources().getConfiguration().orientation;
 if (orientation == Configuration.ORIENTATION_PORTRAIT)
initialOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
 else if (orientation == Configuration.ORIENTATION_LANDSCAPE)
initialOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;

Mark, do you think it's OK ?

Cheers.

Indeed they are not.  The documentation should explain which constants are
appropriate.  The configuration contains an actual orientation, the activity
has a particular orientation *mode* to apply to the activity.
