直接上代碼：

先看下效果圖：

我這里主要做了三個功能：

1.一秒鐘實時定位功能；

2.添加任意經緯度地點到地圖上；

3.判斷朝陽門是否在本人定位范圍1000米內；

百度地圖初始化方法：

DemoApplication.java

package com.qfy.qfymap;import android.app.Application;import com.baidu.mapapi.CoordType; import com.baidu.mapapi.SDKInitializer;public class DemoApplication extends Application {@Overridepublic void onCreate() {super.onCreate();// 在使用 SDK 各組間之前初始化 context 信息，傳入 ApplicationContextSDKInitializer.initialize(this);//自4.3.0起，百度地圖SDK所有接口均支持百度坐標和國測局坐標，用此方法設置您使用的坐標類型.//包括BD09LL和GCJ02兩種坐標，默認是BD09LL坐標。SDKInitializer.setCoordType(CoordType.BD09LL);} }
