汗，查了很久的问题，竟然是重载错函数

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
    }

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState,
                         @Nullable PersistableBundle persistentState){
        super.onCreate(savedInstanceState, persistentState);
    }
