去寻找是否存在该设备类型的适配器
返回所有充电适配器
适配器共有2个
当前需要充电的设备对象是com.adapter.android.Android@659e0bfd
当前需要充电的设备对象是com.adapter.android.Android@659e0bfd
找到适合该设备的适配器com.adapter.android.AndroidAdapter@2a139a55
我是Android充电器
我可以给Android充电
去寻找是否存在该设备类型的适配器
返回所有充电适配器
适配器共有2个
当前需要充电的设备对象是com.adapter.iphone.Iphone@15db9742
找到适合该设备的适配器com.adapter.iphone.IphoneAdapter@6d06d69c
我是iphone充电器
我可以给iphone充电
