我正在使用Robolectric 3.3从com.android.support:appcompat-v7:23.4.0测试AppCompatActivity
我得到之后：
java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
我创建了以下测试运行器：
public class ActivityTestRunner extends RobolectricTestRunner {
public ActivityTestRunner(Class然后我得到：
java.lang.NullPointerException
