在安卓开发中如何在自己设置的经纬度显示到高德地图上中心点

首先创建工程，并在工程Build Path>Configure Build Path…>libraries 中选择“Add Externel JARs…”，选定

MapApijar，点击OK，这样就可以将高德地图Android API 库文件引入。然后在工程Build Path>Configure Build

Path…>Order and Export 中将引入的库文件MapApijar 选中，点击OK，这样您就可以在您的程序中使用高德地图API

了。

二、我们在不熟悉的情况下、先尽量多的添加此软件应用权限；所以在mainifest中添加如下代码；插入的位置在

<application的代码之前。

Java代码

<uses-permission android:name="androidpermissionACCESS_COARSE_LOCATION"></uses-permission>

<uses-permission android:name="androidpermissionACCESS_FINE_LOCATION"></uses-permission>

<uses-permission android:name="androidpermissionINTERNET"></uses-permission>

<uses-permission android:name="androidpermissionACCESS_NETWORK_STATE"></uses-permission>

<uses-permission android:name="androidpermissionWRITE_EXTERNAL_STORAGE"></uses-permission>

<uses-permission android:name="androidpermissionREAD_PHONE_STATE"></uses-permission>

<uses-permission android:name="androidpermissionCHANGE_WIFI_STATE"></uses-permission>

<uses-permission android:name="androidpermissionACCESS_WIFI_STATE"></uses-permission>

三、接着就要在res文件下的layout中添加界面布局了。其代码如下、你可以完全复制进去。

Java代码

<xml version="10" encoding="utf-8">

<LinearLayout xmlns:android=">

使用swift来使用高德地图，这里使用Android实践高德地图包含定位，移动地图动画，获取网络数据，marker标记以及点击，Infowindow自定义界面以及点击，以及点击无marker地图上面隐藏infowindow等功能。直接看代码

@Override

102版本新增方法，设置true表示混合定位中包含gps定位，false表示纯网络定位，默认是true

/

// Location API定位采用GPS和网络混合定位方式，时间最短是2000毫秒

aMapManagerrequestLocationUpdates(

LocationProviderProxyAMapNetwork, 2000, 10, this);

停止定位

举个简单例子吧!假设A1:C10为一张工资表,内容分别是姓名、部门和工资如果要在E2中计算部门为财务科的职工的平均工资可以先找个位置输入条件区域，如H1:H2，其中H1输入部门，H2输入财务科，即H1:H2结果如下：部门财务科该条件区域的功能表示希望计算财务科的相关数据然后在E2中输入公式：=DSUM(A1:C10,3,H1:H2)功能是在A1：C10中查找符合条件区域H1：H2的数据，并计算符合条件区域定义条件的第3列的总和，本题第3列为工资，相当于计算工资的总和。本题的公式也可改为：=DSUM(A1:C10,"工资",H1:H2)
