which is the licence used on this code ? Can I use it on my project ?
please do add a license
I updated the Gist with MIT license, feel free to use it in your projects
This changes the orientation of a screenshot captured by spoon, but it doesn't actually change the orientation of the UI to match. So I'm getting my portrait layout in a landscape screenshot. I'm not registering for configChanges in my manifest either. :(
I found this to actually work: mActivityRule.getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
SystemClock.sleep(100);

On importing your code Android Studio is not finding ActivityLifecycleMonitorRegistry. I'm pretty sure it has to do with my build.gradle file, but I haven't been able to reconcile it so that it imports "android.support.test.internal.runner.lifecycle.ActivityLifecycleMonitorRegistry;"

On importing your code Android Studio is not finding ActivityLifecycleMonitorRegistry.
Same here. Works great without the additional check, though. ;)
I'm getting java.lang.ClassCastException: android.view.ContextThemeWrapper cannot be cast to android.app.Activity
when calling it with onView(isRoot()).perform(orientationLandscape());
The root view's Context doesn't seem to be an Activity…
The ClassCastException
can occur when using AppCompatActivity
- this tends to wrap the Context
in a ContextWrapper
. You may also see a TintContextWrapper
dependent on what you are doing. To get the Activity
you need to unwrap the context using ContextWrapper.getBaseContext()
until you get to an Activity
. NOTE: Activity
itself extends ContextThemeWrapper
This uses recursion which is not obviously ideal but should give you an idea:
public static Activity getActivity(Context context) {
if (context instanceof Activity) {
return (Activity) context;
}
if (context instanceof ContextWrapper) {
return getActivity(((ContextWrapper) context).getBaseContext());
}
return null;
}
Is there an advantage using this instead of e.g. simply activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); ?
Although it works, it was very slow in my case. It does not wait for the orientation to be changed. Same goes for
activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
@mattmook there's nothing keeping you from replacing recursion with a loop:
public static Activity getActivity(Context context) {
while (context instanceof ContextWrapper) {
if (context instanceof Activity) {
return (Activity)context;
}
context = ((ContextWrapper)context).getBaseContext();
}
return null;
}
Thank you very much for so beautiful code. But how to perform Espresso tests on the second Activity? It seems that my tests are still applied on the old instance.
I can use SystemClock.sleep(1000); But is there a way to avoid it? :)
Thank you very much for your great snippet! :)
In case, this doesn't work for you because of (since Android 7.0?) com.android.internal.policy.DecorContext
's baseContext is the Application not an Activity, try out a variation of the following code.
activity = getActivity(view.getContext());
if (activity == null && view instanceof ViewGroup) {
ViewGroup v = (ViewGroup)view;
int c = v.getChildCount();
for (int i = 0; i < c && activity == null; ++i) {
activity = getActivity(v.getChildAt(i).getContext());
}
}
Building upon @TWiStErRob and @simonracz answers I've created a fork of this ViewAction which works fine with Android 7.0 and lower.

@nbarraille Does this work when we use config annotation?
I tried to run Espresso test case, it worked, but not with Robolectric. I guess I might facing robolectric issue!!
@Config(
qualifiers = "port-xxhdpi"
)
Use it like this:
onView(isRoot()).perform(orientationLandscape());
onView(isRoot()).perform(orientationPortrait());
