基于Android的百度地图多功能实现

基于墨卡托投影法、A*算法等理论，调用百度地图应用程序接口（API）的SDKInitializer、MapView和BaiduMap三大核心类方法，设计出一套百度地图的方案. 首先进行密钥申请和清单文件的配置，再自定义一个基类BaseActivity，完成地图界面初始化、调用生命周期方法等预操作. 在基类上进行地图多功能开发，实现了浏览地图、搜寻地点、路线规划、自我定位等应用. 结果表明，多功能百度地图有较好的移植性、实用性，更加贴近用户，能够满足用户搜索、定位等基本功能的实际需求.

Implementation of Multi-Function Baidu Map Based on Android

Based on the theories of Mercator projection and A* algorithm， a set of Baidu map plan was designed by using the methods of three core classes of Baidu map application program interface — SDK Initializer， MapView and BaiduMap. First， the key application and manifest configuration were completed， and then the base class BaseActivity was defined to complete the pre-operation such as the initialization of map interface and the calling of life cycle’s method. By which the multi-function Baidu map was developed and the basic functions of map browsing， specified location search， route planning， positioning， etc. were implemented. The results indicate that the multi-function Baidu map has better portability， practicality and popularization， satisfying the users’ requirement of search and location.
