}

写入一个工具类

public class LocationUtils implements AMapLocationListener {

private AMapLocationClient aMapLocationClient;

private AMapLocationClientOption clientOption;

private ILocationCallBack callBack;

public void startLocate(Context context) {

aMapLocationClient = new AMapLocationClient(context);

//设置监听回调

aMapLocationClient.setLocationListener(this);

//初始化定位参数

clientOption = new AMapLocationClientOption();

clientOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Battery_Saving);

clientOption.setNeedAddress(true);

clientOption.setOnceLocation(false);

//设置是否强制刷新WIFI，默认为强制刷新

clientOption.setWifiActiveScan(true);

//设置是否允许模拟位置,默认为false，不允许模拟位置

clientOption.setMockEnable(false);

//设置定位间隔

clientOption.setInterval(2000);

aMapLocationClient.setLocationOption(clientOption);

aMapLocationClient.startLocation();

}

@Override

public void onLocationChanged(AMapLocation aMapLocation) {

if (aMapLocation != null) {

if (aMapLocation.getErrorCode() == 0) {

//定位成功完成回调

String country = aMapLocation.getCountry();

String province = aMapLocation.getProvince();

String city = aMapLocation.getCity();

String district = aMapLocation.getDistrict();

String street = aMapLocation.getStreet();

double lat = aMapLocation.getLatitude();

double lgt = aMapLocation.getLongitude();

callBack.callBack(country + province + city + district + street, lat, lgt, aMapLocation);

} else {

//显示错误信息ErrCode是错误码，errInfo是错误信息，详见错误码表。

Log.e("AmapError", "location Error, ErrCode:"

+ aMapLocation.getErrorCode() + ", errInfo:"

+ aMapLocation.getErrorInfo());

}

}

}

/**

* 自定义图标

*

* @return

*/

public MarkerOptions getMarkerOption(String str, double lat, double lgt) {

MarkerOptions markerOptions = new MarkerOptions();

markerOptions.icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_launcher));

markerOptions.position(new LatLng(lat, lgt));

markerOptions.title(str);

markerOptions.snippet("纬度:" + lat + " 经度:" + lgt);

markerOptions.period(100);

return markerOptions;

}

public interface ILocationCallBack {

void callBack(String str, double lat, double lgt, AMapLocation aMapLocation);

}

public void setLocationCallBack(ILocationCallBack callBack) {

this.callBack = callBack;

}

}

然后就是高德的代码

public class MainActivity extends AppCompatActivity implements LocationSource {

private MapView myMapView;

private AMap aMap;

private LocationSource.OnLocationChangedListener mListener = null;//定位监听器

private LocationUtils locationUtils;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

myMapView = findViewById(R.id.MapView);

myMapView.onCreate(savedInstanceState);

initView();

}

private void initView() {

if(aMap == null){

aMap = myMapView.getMap();

}

setLocationCallBack();

//设置定位监听

aMap.setLocationSource(this);

//设置缩放级别

aMap.moveCamera(CameraUpdateFactory.zoomTo(15));

//显示定位层并可触发，默认false

aMap.setMyLocationEnabled(true);

}

private void setLocationCallBack(){

locationUtils = new LocationUtils();

locationUtils.setLocationCallBack(new LocationUtils.ILocationCallBack() {

@Override

public void callBack(String str,double lat,double lgt,AMapLocation aMapLocation) {

//根据获取的经纬度，将地图移动到定位位置

aMap.moveCamera(CameraUpdateFactory.changeLatLng(new LatLng(lat,lgt)));

mListener.onLocationChanged(aMapLocation);

//添加定位图标

aMap.addMarker(locationUtils.getMarkerOption(str,lat,lgt));

}

});

}

@Override

public void activate(OnLocationChangedListener onLocationChangedListener) {

mListener = onLocationChangedListener;

locationUtils.startLocate(getApplicationContext());

}

@Override

public void deactivate() {

mListener = null;

}

@Override

protected void onPause() {

super.onPause();

//暂停地图的绘制

myMapView.onPause();

}

@Override

protected void onDestroy() {

super.onDestroy();

//销毁地图

myMapView.onDestroy();

}

@Override

protected void onResume() {

super.onResume();

//重新绘制加载地图

myMapView.onResume();

}

@Override

public void onSaveInstanceState(Bundle outState) {

super.onSaveInstanceState(outState);

myMapView.onSaveInstanceState(outState);

}

}

xml中只需要写入一个MapView就ok

还有一个反编译地理位置的代码,效果图就不上了

public class AddrChangeActivity extends AppCompatActivity implements View.OnClickListener, GeocodeSearch.OnGeocodeSearchListener {

private EditText Addr_Edit;

private Button Zheng_Btn;

private EditText JinDU_Edit;

private EditText WeiDu_Edit;

private Button Fan_Btn;

private TextView Get_Text;

private GeocodeSearch geocodeSearch;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_addr_change);

initView();

//构造 GeocodeSearch 对象，并设置监听。

geocodeSearch = new GeocodeSearch(this);

geocodeSearch.setOnGeocodeSearchListener(this);

//通过GeocodeQuery设置查询参数,调用getFromLocationNameAsyn(GeocodeQuery geocodeQuery) 方法发起请求。

//address表示地址，第二个参数表示查询城市，中文或者中文全拼，citycode、adcode都ok

// GeocodeQuery query = new GeocodeQuery(address, "010");

// geocoderSearch.getFromLocationNameAsyn(query);

}

private void initView() {

Addr_Edit = (EditText) findViewById(R.id.Addr_Edit);

Zheng_Btn = (Button) findViewById(R.id.Zheng_Btn);

JinDU_Edit = (EditText) findViewById(R.id.JinDU_Edit);

WeiDu_Edit = (EditText) findViewById(R.id.WeiDu_Edit);

Fan_Btn = (Button) findViewById(R.id.Fan_Btn);

Get_Text = (TextView) findViewById(R.id.Get_Text);

Zheng_Btn.setOnClickListener(this);

Fan_Btn.setOnClickListener(this);

}

@Override

public void onClick(View v) {

switch (v.getId()) {

case R.id.Zheng_Btn:

String addr = Addr_Edit.getText().toString().trim();

if (addr.isEmpty()) {

Toast.makeText(this, "请输入地址", Toast.LENGTH_SHORT).show();

return;

}

//参数1：addr 地址值 参数2：规定一个区域

GeocodeQuery query = new GeocodeQuery(addr, null);

geocodeSearch.getFromLocationNameAsyn(query);

break;

case R.id.Fan_Btn:

String jingdu = JinDU_Edit.getText().toString().trim();

String weidu = WeiDu_Edit.getText().toString().trim();

if (jingdu.isEmpty() || weidu.isEmpty()) {

Toast.makeText(this, "请输入经纬度", Toast.LENGTH_SHORT).show();

return;

}

//这个是经纬度查询的类

LatLonPoint point = new LatLonPoint(Double.parseDouble(jingdu), Double.parseDouble(weidu));

RegeocodeQuery regeocodeQuery = new RegeocodeQuery(point, 2000000000, GeocodeSearch.AMAP);

GeocodeSearch reSe = new GeocodeSearch(this);

reSe.setOnGeocodeSearchListener(new GeocodeSearch.OnGeocodeSearchListener() {

@Override

public void onRegeocodeSearched(RegeocodeResult regeocodeResult, int i) {

Log.e("onRegeocodeSearched", "onRegeocodeSearched");

RegeocodeAddress address = regeocodeResult.getRegeocodeAddress();

Get_Text.setText(address.getFormatAddress()+"地址");

}

@Override

public void onGeocodeSearched(GeocodeResult geocodeResult, int i) {

}

});

geocodeSearch.getFromLocationAsyn(regeocodeQuery);

break;

}

}

//把经纬度转换成地址

@Override

public void onRegeocodeSearched(RegeocodeResult regeocodeResult, int i) {

Log.e("onRegeocodeSearched", "onRegeocodeSearched");

RegeocodeAddress address = regeocodeResult.getRegeocodeAddress();

Get_Text.setText(address.getFormatAddress());

}

//是吧地址转换成经度纬度

@Override

public void onGeocodeSearched(GeocodeResult geocodeResult, int i) {

Log.e("onGeocodeSearched", "onGeocodeSearched");

//从查出来的结果集 得到地址对象

GeocodeAddress address = geocodeResult.getGeocodeAddressList().get(0);

//从地址对象里面得到 经纬度的类

LatLonPoint latLonPoint = address.getLatLonPoint();

//从这个point取经纬度即可

Get_Text.setText("经度是：" + latLonPoint.getLongitude() + ",纬度是：" + latLonPoint.getLatitude());

}

}

反编译的xml

以上;
