Question

Il est possible d'éviter l'appel à onCreate lorsque vous changez de paysage à portrait?

Comment?

Merci

Answer 1

Absolument possible, AndroidManifest.xml ajouter cette activité à:

android:configChanges="orientation|keyboardHidden"

vous pouvez lire plus d'informations sur cette astuce sur mon article: http://xjaphx.wordpress.com/2011/09/19/the-less-known-over-screen-orientation/

Answer 2

Read this article Handling Runtime Changes. Basically there are two options

1. Let android handle configuration changes - then your activity will be recreated and onCreate will be invoked again.

2. Handle it yourself - then your activity won't be destroyed.

Answer 3

Yes it is possible to do this, by adding android:configChanges="orientation" to your manifest.

However, by choosing this path, you lose much of the great resource management in Android.

If you want to appropriately save and restore state since the activity is recreated without the above manifest change, then you will want to look at onSaveInstanceState () and onRestoreInstanceState ()

Answer 4

add this to manifest of the activity - android:configChanges="orientation"
