android GPS 获取位置

使用GPS权限：

<uses-permissionandroid:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>

Android提供LocationManager和Location，可以方便的获得经纬度、海拔等位置。使用LocationManager来获得位置管理类，从而可以获得历史GPS信息以及位置变化的监听注册；使用Location来获得具体的位置信息。代码如下：

locationm= (LocationManager) getSystemService(LOCATION_SERVICE);

Criteria criteria =newCriteria();

criteria.setAccuracy(Criteria.ACCURACY_FINE);

criteria.setAltitudeRequired(false);

criteria.setBearingRequired(false);

criteria.setCostAllowed(true);

criteria.setPowerRequirement(Criteria.POWER_LOW);

String provider =locationm.getBestProvider(criteria,true);

Location location =locationm.getLastKnownLocation(provider);

//获得上次的记录

gps_loc(location);

LocationListener GPS_listener =newLocationListener() {

//监听位置变化，实时获取位置信息

@Override

publicvoidonStatusChanged(String provider,intstatus,

Bundle extras) {

//TODOAuto-generated method stub

}

@Override

publicvoidonProviderEnabled(String provider) {

//TODOAuto-generated method stub

}

@Override

publicvoidonProviderDisabled(String provider) {

//TODOAuto-generated method stub

}

@Override

publicvoidonLocationChanged(Location location) {

//TODOAuto-generated method stub

//位置发生改变时

gps_loc(location);

}

};

locationm.requestLocationUpdates(provider, 1000, 0, GPS_listener);

}

//获得自己位置

privatevoidgps_loc(Location location) {

if(location !=null) {

self_weidu= location.getLatitude();

self_jindu= location.getLongitude();

}else{

self_weidu= 0;

self_jindu= 0;

}
