android.view.ContextThemeWrapper cannot be cast to android.app.Activity
This line is probably the culprit:
Activity activity = (Activity) v.getContext();
The view v passed to the onClick() method is the same view that you assigned the listener to, so v is the same as holder.parentLayot . I don’t know exactly where holder.parentLayot came from, but chances are very good that (in XML) this view (or one of its parents) has an android:theme attribute.
When a view has the android:theme attribute, it doesn’t use its activity’s context directly. Instead, the android framework will “wrap” the activity’s context in a ContextThemeWrapper in order to modify the view’s theme.
To access the activity from this wrapper, you’ll have to “unwrap” it. Try something like this:
private static Activity unwrap(Context context) { while (!(context instanceof Activity) && context instanceof ContextWrapper) { context = ((ContextWrapper) context).getBaseContext(); } return (Activity) context; }
Then, you can use this method in your onClick() instead of casting the context directly:

Activity activity = unwrap(v.getContext());
Recursive solution in Kotlin:
fun Context.getActivity(): Activity? { return when (this) { is Activity -> this is ContextWrapper -> this.baseContext.getActivity() else -> null } }
Solved: java.lang.ClassCastException: android.app.ContextImpl cannot be cast to android.app.Activity
If you are working on Android application or AAR Library, you will be using applications context frequently for accessing android system API’s.While using those API’s which are dependent on Context, there are chances you may see an error like as below,
System.err: java.lang.ClassCastException: android.app.ContextImpl cannot be cast to android.app.Activity
Solution :
When we encountered this error in to accessing one of our library, we were passing Context to library API using getBaseContext() API whereas our library was expecting application context, hence solution which worked was,
Change getBaseContext() to “this” while calling the library function.
