我面临一个问题,即给共同的偏好带来一个变量。 我正在从联络员那里获得联系人、姓名和号码,然后将其保留到共同的偏好,以便我能够在另一个活动中利用他们建立一个数据库,但每次都把他们带到另一个活动中,在我要求名字或假问时给我打电话的次数?

页: 1 联系信息活动

id "displays the id"
name "displays name"
phone "displays phone"

第二次活动

id "displays phone number"
name "displays phone number"
phone "displays phone number"

i dont get it?
