butterKnife@BindView报错: If this view is optional add '@Nullable' annotation

使用ButterKnife 8.2的时候遇到这个问题很明显空指针问题按照提示添加

import android.support.annotation.Nullable;@Nullable

造成原因如下：

ButterKnife 没有

ButterKinfe.Bind(this); 或者ButterKnife.Bind(this,view)

我是在BaseActivity中添加ButterKnife.Bind(this) 报错的果然还是我太天真了这样是找不到的。
