* 派生自Checkable接口,使CheckableImageView具有的可选中的状态
* ,但当用户点击选中时,我们感觉会调用selector的state_checked="true"的状态,
* 但state_checked属性对ImageView是无效的
* ,因为ImageView并不具有可选中的属性,所以我们在调用selector前,应该为ImageView添加上state_checked属性
* 这就是重写onCreateDrawableState
* ()的原因,当用户选中时,给ImageView设置选中状态,强制使它处于选中状态中,这时,它就会调用我们的state_checked属性
