getActivity在ActivityUnitTestCase中返回null

Question

如果getActivity（）总是返回null，如何在android测试中获取活动？

public class PageDistrListTest extends ActivityUnitTestCase<PageDistrList> {

PageDistrList activity;

  @Override
  protected void setUp() throws Exception {
        super.setUp();
        activity = getActivity();
        headerRecycler = (RecyclerView) activity.findViewById(R.id.page_tab_distr_recycler_header);
    }
}

Answer 1

您将获得此类活动实例

activity = launchActivity("package.PageDistrList", PageDistrList.class, null);
