Oreo中AppcompactActivity的onCreate（）方法的IllegalstateException

Question

我正在使用@ style / Theme.AppCompat.Light.Dialog.NoActionBar主题来显示Dialog Activity.It在Oreo下工作得很好但是在oreo中崩溃了：

public class AdvancePaintActivity extends AppCompatActivity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        setContentView(R.layout.activity_paint_advance); 
    }
