大部分的功能其实在 安卓地图SDK 中可以找到..因为包含了一系列的实例代码，所以很方便，但是为什么没有直接链接写下来结束呢？是因为中间遇到了一些小的问题.----定位不到,当然现在也能实现了(解决方案如下定位部分)，下面是我的一些小的建议和转载的一些文章
其实更加重要的是地图开发的一些文档，索要仔细阅读，以及xml的配置.
开发环境的配置请访问：http://lbs.amap.com/api/android-sdk/summary/
一、 要实现高德地图定位呢，首先需要做好以下几步准备：
1. 在高德开放平台注册帐号
注册地址：http://lbs.amap.com
2. 在开发中下载Android平台下的地图SDK和定位SDK文件
进入相关下载下载自己想要的功能或文件，图只是截取了地图SDK的页面，定位SDK也是一样，按自己想要的文件下载。下载完成后解压得到：
- 3D地图包解压后得到：3D地图显示包“AMap_3DMap_VX.X.X_时间.jar”和库文件夹（包含armeabi、arm64-v8a等库文件）。
- 2D地图包解压后得到：2D地图显示包“AMap_2DMap_VX.X.X_时间.jar ”
- 定位SDK下载并解压得到定位包“AMap_Location_V2.x.x.jar“
3. 添加jar包，将jar包放入工程的libs目录下。 
对于每个jar文件，右键-选择Add As Library，导入到工程中。或者使用菜单栏 选择 File ->Project Structure->Modules-> Dependencies。点击绿色的加号选择File dependency. 然后选择要添加的jar包即可，此时build.gradle中会自动生成如下信息。 
4. 申请API KEY
进入控制台
创建自己的应用（创建过程内需要的SHA1已经的博客讲过）
开发环境已经配置好了，接下来就是敲代码了。
二、 首先我们要做的就是将地图显示出来，通过以下几步操作，即可在应用中使用高德地图SDK：
第一步：添加用户key 在工程的“ AndroidManifest.xml ”文件如下代码中添加您的用户 Key。
<code class="hljs perl has-numbering" style="display: block; padding: 0.5em; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"> <application android:allowBackup=<span class="hljs-string" style="color: rgb(0, 136, 0);">"true"</span> android:icon=<span class="hljs-string" style="color: rgb(0, 136, 0);">"<span class="hljs-variable" style="color: rgb(102, 0, 102);">@mipmap</span>/ic_launcher"</span> android:label=<span class="hljs-string" style="color: rgb(0, 136, 0);">"<span class="hljs-variable" style="color: rgb(102, 0, 102);">@string</span>/app_name"</span> android:supportsRtl=<span class="hljs-string" style="color: rgb(0, 136, 0);">"true"</span> android:theme=<span class="hljs-string" style="color: rgb(0, 136, 0);">"<span class="hljs-variable" style="color: rgb(102, 0, 102);">@style</span>/AppTheme"</span>> <meta-data android:name=<span class="hljs-string" style="color: rgb(0, 136, 0);">"com.amap.api.v2.apikey"</span> android:value=<span class="hljs-string" style="color: rgb(0, 136, 0);">"c9df032baec3ec50b1e089768ea4672b"</span> /></code>
第二步：添加所需权限 在工程的“ AndroidManifest.xml ”文件中进行添加。
<code class="hljs lasso has-numbering" style="display: block; padding: 0.5em; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span class="hljs-comment" style="color: rgb(136, 0, 0);">//地图包、搜索包需要的基础权限</span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.INTERNET"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.WRITE_EXTERNAL_STORAGE"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_NETWORK_STATE"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_WIFI_STATE"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.READ_PHONE_STATE"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_COARSE_LOCATION"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span> <span class="hljs-comment" style="color: rgb(136, 0, 0);">//定位包、导航包需要的额外权限（注：基础权限也需要）</span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_FINE_LOCATION"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_MOCK_LOCATION"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span> <span class="hljs-subst"><</span>uses<span class="hljs-attribute">-permission</span> android:name<span class="hljs-subst">=</span><span class="hljs-string" style="color: rgb(0, 136, 0);">"android.permission.CHANGE_WIFI_STATE"</span> <span class="hljs-subst">/</span><span class="hljs-subst">></span></code>
第三步：在布局xml文件中添加地图控件。
<code class="hljs avrasm has-numbering" style="display: block; padding: 0.5em; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><<span class="hljs-keyword" style="color: rgb(0, 0, 136);">com</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68);">.amap</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68);">.api</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68);">.maps</span>2d<span class="hljs-preprocessor" style="color: rgb(68, 68, 68);">.MapView</span> android:id=<span class="hljs-string" style="color: rgb(0, 136, 0);">"@+id/map_view"</span> android:layout_width=<span class="hljs-string" style="color: rgb(0, 136, 0);">"match_parent"</span> android:layout_height=<span class="hljs-string" style="color: rgb(0, 136, 0);">"match_parent"</span> /></code>
第四步，创建地图Activity，管理地图生命周期。
<code class="hljs java has-numbering" style="display: block; padding: 0.5em; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span class="hljs-keyword" style="color: rgb(0, 0, 136);">public</span> <span class="hljs-class"><span class="hljs-keyword" style="color: rgb(0, 0, 136);">class</span> <span class="hljs-title" style="color: rgb(102, 0, 102);">MainActivity</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">extends</span> <span class="hljs-title" style="color: rgb(102, 0, 102);">Activity</span> {</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">private</span> MapView mMapView = <span class="hljs-keyword" style="color: rgb(0, 0, 136);">null</span>; <span class="hljs-annotation" style="color: rgb(155, 133, 157);">@Override</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">protected</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">void</span> <span class="hljs-title">onCreate</span>(Bundle savedInstanceState) { <span class="hljs-keyword" style="color: rgb(0, 0, 136);">super</span>.onCreate(savedInstanceState); setContentView(R.layout.activity_main); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//获取地图控件引用</span> mMapView = (MapView) findViewById(R.id.map); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//在activity执行onCreate时执行mMapView.onCreate(savedInstanceState)，实现地图生命周期管理</span> mMapView.onCreate(savedInstanceState); } <span class="hljs-annotation" style="color: rgb(155, 133, 157);">@Override</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">protected</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">void</span> <span class="hljs-title">onDestroy</span>() { <span class="hljs-keyword" style="color: rgb(0, 0, 136);">super</span>.onDestroy(); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理</span> mMapView.onDestroy(); } <span class="hljs-annotation" style="color: rgb(155, 133, 157);">@Override</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">protected</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">void</span> <span class="hljs-title">onResume</span>() { <span class="hljs-keyword" style="color: rgb(0, 0, 136);">super</span>.onResume(); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//在activity执行onResume时执行mMapView.onResume ()，实现地图生命周期管理</span> mMapView.onResume(); } <span class="hljs-annotation" style="color: rgb(155, 133, 157);">@Override</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">protected</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">void</span> <span class="hljs-title">onPause</span>() { <span class="hljs-keyword" style="color: rgb(0, 0, 136);">super</span>.onPause(); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//在activity执行onPause时执行mMapView.onPause ()，实现地图生命周期管理</span> mMapView.onPause(); } <span class="hljs-annotation" style="color: rgb(155, 133, 157);">@Override</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">protected</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">void</span> <span class="hljs-title">onSaveInstanceState</span>(Bundle outState) { <span class="hljs-keyword" style="color: rgb(0, 0, 136);">super</span>.onSaveInstanceState(outState); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//在activity执行onSaveInstanceState时执行mMapView.onSaveInstanceState (outState)，实现地图生命周期管理</span> mMapView.onSaveInstanceState(outState); } }</code>注意：一定要有mMapView.onCreate(savedInstanceState);
运行一下，效果如下：
三、接下来就是实现定位了，定位也需要通过以下几步操作完成：
第一步：配置AndroidManifest.xml ------该步骤也是我定位的时候没有添加的..
1.在application标签中声明service组件,每个app拥有自己单独的定位service。
<code class="hljs xml has-numbering" style="display: block; padding: 0.5em; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span style="color:#ff0000;"> <span class="hljs-tag"><<span class="hljs-title">service</span> <span class="hljs-attribute">android:name</span>=<span class="hljs-value">"com.amap.api.location.APSService"</span>/></span></span></code>
2.接下来声明使用权限
<code class="hljs xml has-numbering" style="display: block; padding: 0.5em; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span class="hljs-comment" style="color: rgb(136, 0, 0);"><!--用于进行网络定位--></span> <span class="hljs-tag" style="color: rgb(0, 102, 102);"><<span class="hljs-title" style="color: rgb(0, 0, 136);">uses-permission</span> <span class="hljs-attribute" style="color: rgb(102, 0, 102);">android:name</span>=<span class="hljs-value" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_COARSE_LOCATION"</span> /></span> <span class="hljs-comment" style="color: rgb(136, 0, 0);"><!--用于访问GPS定位--></span> <span class="hljs-tag" style="color: rgb(0, 102, 102);"><<span class="hljs-title" style="color: rgb(0, 0, 136);">uses-permission</span> <span class="hljs-attribute" style="color: rgb(102, 0, 102);">android:name</span>=<span class="hljs-value" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_FINE_LOCATION"</span> /></span> <span class="hljs-comment" style="color: rgb(136, 0, 0);"><!--获取运营商信息，用于支持提供运营商信息相关的接口--></span> <span class="hljs-tag" style="color: rgb(0, 102, 102);"><<span class="hljs-title" style="color: rgb(0, 0, 136);">uses-permission</span> <span class="hljs-attribute" style="color: rgb(102, 0, 102);">android:name</span>=<span class="hljs-value" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_NETWORK_STATE"</span> /></span> <span class="hljs-comment" style="color: rgb(136, 0, 0);"><!--用于访问wifi网络信息，wifi信息会用于进行网络定位--></span> <span class="hljs-tag" style="color: rgb(0, 102, 102);"><<span class="hljs-title" style="color: rgb(0, 0, 136);">uses-permission</span> <span class="hljs-attribute" style="color: rgb(102, 0, 102);">android:name</span>=<span class="hljs-value" style="color: rgb(0, 136, 0);">"android.permission.ACCESS_WIFI_STATE"</span> /></span> <span class="hljs-comment" style="color: rgb(136, 0, 0);"><!--这个权限用于获取wifi的获取权限，wifi信息会用来进行网络定位--></span> <span class="hljs-tag" style="color: rgb(0, 102, 102);"><<span class="hljs-title" style="color: rgb(0, 0, 136);">uses-permission</span> <span class="hljs-attribute" style="color: rgb(102, 0, 102);">android:name</span>=<span class="hljs-value" style="color: rgb(0, 136, 0);">"android.permission.CHANGE_WIFI_STATE"</span> /></span> <span class="hljs-comment" style="color: rgb(136, 0, 0);"><!--用于访问网络，网络定位需要上网--></span> <span class="hljs-tag" style="color: rgb(0, 102, 102);"><<span class="hljs-title" style="color: rgb(0, 0, 136);">uses-permission</span> <span class="hljs-attribute" style="color: rgb(102, 0, 102);">android:name</span>=<span class="hljs-value" style="color: rgb(0, 136, 0);">"android.permission.INTERNET"</span> /></span> <span class="hljs-comment" style="color: rgb(136, 0, 0);"><!--用于读取手机当前的状态--></span> <span class="hljs-tag" style="color: rgb(0, 102, 102);"><<span class="hljs-title" style="color: rgb(0, 0, 136);">uses-permission</span> <span class="hljs-attribute" style="color: rgb(102, 0, 102);">android:name</span>=<span class="hljs-value" style="color: rgb(0, 136, 0);">"android.permission.READ_PHONE_STATE"</span> /></span> <span class="hljs-comment" style="color: rgb(136, 0, 0);"><!--写入扩展存储，向扩展卡写入数据，用于写入缓存定位数据--></span> <span class="hljs-tag" style="color: rgb(0, 102, 102);"><<span class="hljs-title" style="color: rgb(0, 0, 136);">uses-permission</span> <span class="hljs-attribute" style="color: rgb(102, 0, 102);">android:name</span>=<span class="hljs-value" style="color: rgb(0, 136, 0);">"android.permission.WRITE_EXTERNAL_STORAGE"</span> /></span></code>
第二步：启动定位功能：
1. 在主线程中获得地图对象AMap，并设置定位监听且实现LocationSource接口：<code class="hljs java has-numbering" style="display: block; padding: 0.5em; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span class="hljs-keyword" style="color: rgb(0, 0, 136);">public</span> <span class="hljs-class"><span class="hljs-keyword" style="color: rgb(0, 0, 136);">class</span> <span class="hljs-title" style="color: rgb(102, 0, 102);">MainActivity</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">extends</span> <span class="hljs-title" style="color: rgb(102, 0, 102);">Activity</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136);">implements</span> <span class="hljs-title" style="color: rgb(102, 0, 102);">LocationSource</span>{</span></code><code class="hljs cs has-numbering" style="display: block; padding: 0.5em; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span class="hljs-keyword" style="color: rgb(0, 0, 136);">if</span> (aMap == <span class="hljs-keyword" style="color: rgb(0, 0, 136);">null</span>) { aMap = mapView.getMap(); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//设置显示定位按钮 并且可以点击</span> UiSettings settings = aMap.getUiSettings(); aMap.setLocationSource(<span class="hljs-keyword" style="color: rgb(0, 0, 136);">this</span>);<span class="hljs-comment" style="color: rgb(136, 0, 0);">//设置了定位的监听,这里要实现LocationSource接口</span> <span class="hljs-comment" style="color: rgb(136, 0, 0);">// 是否显示定位按钮</span> settings.setMyLocationButtonEnabled(<span class="hljs-keyword" style="color: rgb(0, 0, 136);">true</span>); aMap.setMyLocationEnabled(<span class="hljs-keyword" style="color: rgb(0, 0, 136);">true</span>);<span class="hljs-comment" style="color: rgb(136, 0, 0);">//显示定位层并且可以触发定位,默认是flase</span> }</code>2. 配置定位参数，启动定位<code class="hljs cs has-numbering" style="display: block; padding: 0.5em; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span class="hljs-comment" style="color: rgb(136, 0, 0);">//初始化定位</span> mLocationClient = <span class="hljs-keyword" style="color: rgb(0, 0, 136);">new</span> AMapLocationClient(getApplicationContext()); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//设置定位回调监听，这里要实现AMapLocationListener接口，AMapLocationListener接口只有onLocationChanged方法可以实现，用于接收异步返回的定位结果，参数是AMapLocation类型。</span> mLocationClient.setLocationListener(<span class="hljs-keyword" style="color: rgb(0, 0, 136);">this</span>); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//初始化定位参数</span> mLocationOption = <span class="hljs-keyword" style="color: rgb(0, 0, 136);">new</span> AMapLocationClientOption(); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//设置定位模式为Hight_Accuracy高精度模式，Battery_Saving为低功耗模式，Device_Sensors是仅设备模式</span> mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//设置是否返回地址信息（默认返回地址信息）</span> mLocationOption.setNeedAddress(<span class="hljs-keyword" style="color: rgb(0, 0, 136);">true</span>); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//设置是否只定位一次,默认为false</span> mLocationOption.setOnceLocation(<span class="hljs-keyword" style="color: rgb(0, 0, 136);">false</span>); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//设置是否强制刷新WIFI，默认为强制刷新</span> mLocationOption.setWifiActiveScan(<span class="hljs-keyword" style="color: rgb(0, 0, 136);">true</span>); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//设置是否允许模拟位置,默认为false，不允许模拟位置</span> mLocationOption.setMockEnable(<span class="hljs-keyword" style="color: rgb(0, 0, 136);">false</span>); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//设置定位间隔,单位毫秒,默认为2000ms</span> mLocationOption.setInterval(<span class="hljs-number" style="color: rgb(0, 102, 102);">2000</span>); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//给定位客户端对象设置定位参数</span> mLocationClient.setLocationOption(mLocationOption); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//启动定位</span> mLocationClient.startLocation()</code>
高精度定位模式：
在这种定位模式下，将同时使用高德网络定位和GPS定位,优先返回精度高的定位低功耗定位模式：
在这种模式下，将只使用高德网络定位仅设备定位模式：
在这种模式下，将只使用GPS定位。 3. 实现AMapLocationListener接口，获取定位结果：
