android中switch中case通过枚举来实现

实例一（枚举为int类型）:

public enum usb_action{

    USB_ACTION_UNKNOWN,

    USB_ACTION_ATTACH,

    USB_ACTION_DETACH,

};

 

public Handler mHandler=new Handler() 

{ 

    public void handleMessage(Message msg) 

    {

        usb_action curUsbAction = usb_action.values()[msg.what]; //do your own bounds checking

        switch(curUsbAction) 

        {

        case USB_ACTION_UNKNOWN:

            //do sth.

            break; 

        default: 

            break;       

        } 

        super.handleMessage(msg); 

    }

};

实例二（枚举为string类型）:

public enum week {
LOGIN, REGISTER, INVITATION, POSTER, DOWNLOAD, RESERVED
};

 

week  ati = week .valueOf(ad.getAdGuid());//   ad.getAdGuid()获取String
switch (ati) {
case LOGIN:

break;
case REGISTER:

break;
case INVITATION:

break;
case POSTER:
break;
case DOWNLOAD:

break;
case RESERVED:

break;
default:
break;
}
