Cannot mock android.widget.TextView

What steps will reproduce the problem?
1. In an ActivityInstrumentationTestCase2, create a mock of a TextView

What is the expected output? What do you see instead?

Expect to get a mock, but get an exception.

I am able to mock other widget classes (ViewFlipper, ImageView etc) but when I 
try to create a mock of a TextView I get the following exception at runtime:

Seems an NPE is being thrown within the TextView constructor.  I am creating 
the mock as follows:

AndroidMock.createMock(TextView.class, getActivity());

May be an Android API issue, but I have verified that I can call the equivalent 
constructor manually:

new TextView(getActivity());

without any problems.

Other mocks:

AndroidMock.createMock(ImageView.class, getActivity());

... appear to work as expected.
