[SwitchPreference]代码中动态修改SwitchPreference的Thumb或Track颜色
所有自定义代码在下面▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼
逻辑就是自定义个class继承SwitchPreference,拿到switch,给switch设置checkChange监听就可以了;
解释下为何holder.findViewById(16908352)中id是16908352呢?因为我们是继承自support-v14中的SwitchPreference,(注意:不是android.preference.SwitchPreference,这个已经被弃用了),查看SwitchPreference中onBindViewHoldr的代码,它的Switch是局部变量,所以我们是无法继承的,但已知switch的id是16908352,所以我们直接拿过来用就可以了,不用纠结它的id常量名是什么.
