一、引入和配置
1.引入相关的sdk
//高德地图sdk相关
implementation 'com.amap.api:navi-3dmap:latest.integration'//导航
implementation 'com.amap.api:search:latest.integration'//搜索
implementation 'com.amap.api:location:latest.integration'//定位`
注意导航和3d地图implementation 'com.amap.api:3dmap:latest.integration'不能同时导入，否则报错
注意导航和2d地图implementation 'com.amap.api:map2d:latest.integration'不能同时导入，否则报错
2.创建应用，添加key
https://lbs.amap.com/dev/key/app
<application
android:icon="@drawable/icon"
android:label="@string/app_name" >
<meta-data
android:name="com.amap.api.v2.apikey"
android:value="请输入您的用户Key"/>
……
</application>
3.在AndroidManifest.xml配置权限
<!--允许程序打开网络套接字-->
<uses-permission android:name="android.permission.INTERNET" />
<!--允许程序设置内置sd卡的写权限-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!--允许程序获取网络状态-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!--允许程序访问WiFi网络信息-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!--允许程序读写手机状态和身份-->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!--允许程序访问CellID或WiFi热点来获取粗略的位置-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
4.混淆
3D 地图 V5.0.0之前：
-keep class com.amap.api.maps.**{*;}
-keep class com.autonavi.amap.mapcore.*{*;}
-keep class com.amap.api.trace.**{*;}
3D 地图 V5.0.0之后：
-keep class com.amap.api.maps.**{*;}
-keep class com.autonavi.**{*;}
-keep class com.amap.api.trace.**{*;}
定位
-keep class com.amap.api.location.**{*;}
-keep class com.amap.api.fence.**{*;}
-keep class com.autonavi.aps.amapapi.model.**{*;}
搜索
-keep class com.amap.api.services.**{*;}
2D地图
-keep class com.amap.api.maps2d.**{*;}
-keep class com.amap.api.mapcore2d.**{*;}
导航
-keep class com.amap.api.navi.**{*;}
-keep class com.autonavi.**{*;}
二、地图显示和定位
1.定位
//初始化定位
AMapLocationClient mLocationClient;
private void locationInit() {
//初始化定位
mLocationClient = new AMapLocationClient(this.getActivity().getApplicationContext());
//设置定位回调监听
mLocationClient.setLocationListener(new AMapLocationListener() {
@Override
public void onLocationChanged(AMapLocation aMapLocation) {
L.e(TAG,aMapLocation.toString());
mBinding.tvLocation.setText(aMapLocation.getAoiName());
}
});
//初始化AMapLocationClientOption对象
AMapLocationClientOption mLocationOption = new AMapLocationClientOption();
//设置定位场景，目前支持三种场景（签到、出行、运动，默认无场景）
mLocationOption.setLocationPurpose(AMapLocationClientOption.AMapLocationPurpose.SignIn);
mLocationOption.setOnceLocation(true);//获取一次定位结果
//给定位客户端对象设置定位参数
mLocationClient.setLocationOption(mLocationOption);
//启动定位
mLocationClient.startLocation();
}
@Override
public void onDestroy() {
super.onDestroy();
if (mLocationClient!=null){
mLocationClient.stopLocation();
mLocationClient.onDestroy();
}
}
private void getLocationPermission(){
AndPermission.with(this)
.runtime()
.permission(Permission.ACCESS_COARSE_LOCATION,Permission.ACCESS_FINE_LOCATION)
.onGranted(permissions -> {
//异步查询
locationInit();
})
.onDenied(permissions -> {
new XPopup.Builder(this.getActivity())
.asConfirm("权限申请","读取视频文件，需要获取【存储】的权限，去设置开启？",
"取消","去设置",
() -> AppUtils.goIntentSetting(this.getActivity()),null,true).show();
})
.start();
}
2.显示地图,并定位到自己位置
image.png
2.1.布局中创建
<com.amap.api.maps.MapView
android:id="@+id/map_view"
android:layout_width="match_parent"
android:layout_height="200dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/include6" />
2.2.获取地图，并设置定位到自己当前位置
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ImmersionBar.with(this).hideBar(BarHide.FLAG_HIDE_NAVIGATION_BAR).statusBarDarkFont(true).init();
db.mapView.onCreate(savedInstanceState);
initMap();
initView();
}
private void initMap() {
AMap aMap = db.mapView.getMap();
aMap.setMyLocationEnabled(true);
}
@Override
protected void onDestroy() {
super.onDestroy();
//在activity执行onDestroy时执行mMapView.onDestroy()，销毁地图
db.mapView.onDestroy();
}
@Override
protected void onResume() {
super.onResume();
//在activity执行onResume时执行mMapView.onResume ()，重新绘制加载地图
db.mapView.onResume();
}
@Override
protected void onPause() {
super.onPause();
//在activity执行onPause时执行mMapView.onPause ()，暂停地图的绘制
db.mapView.onPause();
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//在activity执行onSaveInstanceState时执行mMapView.onSaveInstanceState (outState)，保存地图当前的状态
db.mapView.onSaveInstanceState(outState);
}
private void initView() {
tvTitle.setText("选择地址");
}

三、poi检索的时候需要选择省份，然后通过关键字检索
private String[] provinceList =new String[]{"北京市", "天津市", "重庆市","上海市","河北省", "山西省", "辽宁省", "吉林省",
"黑龙江省", "江苏省", "浙江省", "安徽省", "福建省", "江西省", "山东省","河南省", "湖北省", "湖南省", "广东省", "海南省","四川省",
"贵州省", "云南省", "陕西省", "甘肃省", "青海省","台湾省","西藏自治区", "内蒙古自治区","广西壮族自治区","宁夏回族自治区",
"新疆维吾尔自治区", "香港特别行>政区", "澳门特别行政区"};
把上面的34省份选择一个后作为cityCode,再传入对应的关键字，就可以检索出来poi列表信息
int currentPage=1;
PoiSearch.Query query;
PoiSearch poiSearch;
private void getPoi(String keyWord){
//keyWord表示搜索字符串，第二个参数表示POI搜索类型,cityCode表示POI搜索区域
query = new PoiSearch.Query(keyWord, "", cityCode);
query.setPageSize(20);
query.setPageNum(currentPage);//设置查询页码
poiSearch = new PoiSearch(this, query);
poiSearch.setOnPoiSearchListener(new PoiSearch.OnPoiSearchListener() {
@Override
public void onPoiSearched(PoiResult poiResult, int i) {
ArrayList<PoiItem> pois = poiResult.getPois();
if (pois!=null&&pois.size()>0){
if (currentPage==1){
//地图移动到第一个检索POI位置
mAdapter.setNewData(pois);
}else mAdapter.addData(pois);
mAdapter.loadMoreComplete();
}else mAdapter.loadMoreEnd();
}
@Override
public void onPoiItemSearched(PoiItem poiItem, int i) {
}
});
poiSearch.searchPOIAsyn();
}

四、异常相关
异常一：More than one file was found with OS independent path 'assets/location_map_gps_locked.png'
发现
image.png
解决方案：在
Module:app中的android中写入
packagingOptions {
exclude 'assets/location_map_gps_locked.png'
exclude 'assets/location_map_gps_3d.png'
}
异常二：javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found`
导致无法定位和检索poi
网络设置了代理，导致
