Change layout without calling onCreate

I have an activity with two layout files, one each for portrait and landscape modes. I see that the onCreate method is called each time I change orientation. I tried using

android:configChanges = "orientation"

in the manifest file, but it only reads the portrait layout. Is there a way I can set the layout to the landscape mode without calling onCreate?

If you use android:configChanges = "orientation", you must override the onConfigurationChanged(...) method of your Activity. Check the newConfig parameter for the new orientation then manually set the layout you want.

See the following links:

onConfigurationChanged(Configuration newConfig)

If you want your activity be only in landscape mode, you set this attribute for the activity in the AndroidManifest.xml:

        android:screenOrientation="landscape"

You can put your layout.xml files in such folders for different screen orientations:

  • res\layout-land
  • res\layout-port

This is a fact of life with android. You need to develop your activity around the fact it can be destroyed at any minute due to a configuration change like the screen's orientation changing. Save all the the information used to build the screen in on pause and recreate it in onCreate.

You could create two layout folders. One for portrait mode and one for landscape. layout and layout-land.
