Android how to test orientation change

Question

I have an issue regarding unit testing android orientation shifts. I have both Portrait and Landscape supported in my application and I have to test if the views hierarchy is correctly drawn when the orientation changes.

I have created two test methods to check this, and I have something like this:

public void testOnCreate() throws Exception {
    //Check all the activity components
    assertNotNull(activity);
    assertNotNull(application);

    //Check if the rights components are available on the screen
    assertNotNull(LayoutInflater.from(activity));
    activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    testOrientationPortrait();
}

On this particular case the tests pass, and the view hierarchy is drawn correctly. But when I try to test the landscape using:

public void testOrientationChange() throws Exception {
    assertNotNull(activity);
    activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

    //Check if the rights components are available on the screen
    assertNotNull(LayoutInflater.from(activity));
    testOrientationLandscape();
}

The orientation changes, but the view hierarchy fails, because views have the attributes from portrait.

Any ideas how to fix this?

Thanks, Ark

Well that shows me how to check for orientation. But the orientation is the only one that changes, for me. I need to be able to reinflate the new xml containing the view hierarchy for landscape. — Aurelian Cotuna, Jan 28 '13 at 13:22

Override this method and do your changes in the method:

@Override
 public void onConfigurationChanged(Configuration newConfig) {
  // TODO Auto-generated method stub
  super.onConfigurationChanged(newConfig);


 }

Do not forget to add

 <activity

        android:configChanges="orientation"
        >
    </activity>

in your menifest.

And this can be used just to check the orientation . getResources().getConfiguration().orientation

`configChanges` is used when you have the same layout for both of the orientation, because views don't need to be redrawn, but I have separate layouts for land and protrait, so I don't used `configChanges` at all. So this doesn't help me at all. – Aurelian Cotuna Jan 28 '13 at 13:35

This gives the orientation if(newConfig.orientation==Configuration.ORIENTATION_LANDSCAPE){ Log.e("On Config Change","LANDSCAPE"); }else{ Log.e("On Config Change","PORTRAIT"); } – Payal Jan 28 '13 at 13:50
Yes I know. But as I said before, the orientation is changed, but the views have wrong attributes, because they are not redrawn for the new orientation. For instance I run the tests for the portrait, everything is ok, I run the tests for landscape, the orientation changes, but the views attributes remain the same. – Aurelian Cotuna Jan 28 '13 at 14:41
