Android获取地理坐标 Android 通过经纬度获取地理位置信息

首先获取LocationManager、Location及Criteria

LocationManager locationManager;

String context = Context.LOCATION_SERVICE;

locationManager = (LocationManager) getSystemService(context);

Criteria criteria = new Criteria();

criteria.setAccuracy(Criteria.ACCURACY_FINE);

criteria.setAltitudeRequired(false);

criteria.setBearingRequired(false);

criteria.setCostAllowed(false);

criteria.setPowerRequirement(Criteria.POWER_LOW);

String provider = locationManager.getBestProvider(criteria,

true);

Location location = locationManager

.getLastKnownLocation(provider);

Criteria 类介绍：

Criteria是“精确度”的意思，Criteria类提供若干个查询条件：

(1) public void setAccuracy(int accuracy)

位置解析的精度，高或低

参数： Criteria. ACCURACY_FINE，精确模式；

Criteria. ACCURACY_COARSE，模糊模式；

(2) public void setAltitudeRequired(booleanaltitudeRequired)

是否提供海拔高度信息，是或否

(3) public void setBearingRequired(boolean bearingRequired)

是否提供方向信息，是或否

(4) public void setCostAllowed(boolean costAllowed)

是否允许运营商计费，是或否

(5) public voidsetPowerRequirement(int level)

电池消耗，无、低、中、高，参数 Criteria. NO_REQUIREMENT,Criteria. POWER_LOW,Criteria. POWER_MEDIUM, orCriteria. POWER_HIGH,

(6) public voidsetSpeedRequired(boolean speedRequired)

是否提供速度信息，是或否

获取地理信息函数：

private void updateWithNewLocation(Location location) {

String coordinate;

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

String addressStr = "no address \n";

if (location != null) {

double lat = location.getLatitude();

double lng = location.getLongitude();

coordinate = "Latitude：" + lat + "\nLongitude：" + lng;

double latitude = location.getLatitude();

double longitude = location.getLongitude();

Geocoder geocoder = new Geocoder(context, Locale.getDefault());

try {

Listaddresses = geocoder.getFromLocation(latitude,

longitude, 1);

StringBuilder sb = new StringBuilder();

if (addresses.size() > 0) {

Address address = addresses.get(0);

for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {

sb.append(address.getAddressLine(i)).append("\n");

}

sb.append(address.getLocality()).append("\n");

sb.append(address.getLocality()).append("\n");

sb.append(address.getCountryName());

addressStr = sb.toString();

}

} catch (IOException e) {

e.printStackTrace();

}

} else {

coordinate = "no coordinate!\n";

}

loc.setText("your coordinate：\n" + coordinate + "\n"

+ addressStr);

}
