資源簡介

大概思路： 1）創(chuàng)建項目，上傳應(yīng)用到百度定位sdk獲得應(yīng)用對應(yīng)key，并配置定位服務(wù)成功。 2）將配置的定位代碼塊放入service中，使程序在后臺不斷更新經(jīng)緯度 3）為應(yīng)用創(chuàng)建數(shù)據(jù)庫和相應(yīng)的數(shù)據(jù)表，編寫 增刪改查 業(yè)務(wù)邏輯方法 4）編寫界面，通過點擊按鈕控制是否開始計算距離，并引用數(shù)據(jù)庫，初始化表數(shù)據(jù)，實時刷新界面 5）在service的定位代碼塊中計算距離，并將距離和經(jīng)緯度實時的保存在數(shù)據(jù)庫(注：只要經(jīng)緯度發(fā)生改變，計算出來的距離就要進行保存) 6）界面的刷新顯示
