这是我的数据库:

{
  "UID1" : {
    "KEY" : {
      "Name" : "name1",
      "Email" : "something1@something.com",
      "userid" : "UID1"
    }
  },
  "UID2" : {
    "KEY2" : {
      "Name" : "name1",
      "Email" : "something1@something.com",
      "userid" : "UID2"
    },
    "KEY3" : {
      "Name" : "name2",
      "Email" : "something2@something.com",
      "userid" : "UID2"
    },
    "KEY4" : {
      "Name" : "name3",
      "Email" : "something3@something.com",
      "userid" : "UID2"
  }
}

我想更新和删除例如位于"KEY2"位置的数据.

我怎样才能做到这一点？我尚未在Android中尝试过任何代码.
