我去，好久对没来os来了编辑器都有三种风格了，这愉快的周末即将开始，下午了，来个gps是如何定位的，Android版本的，ios的请绕走。
首先还是需要引入你的权限，在AndroidManifest.xml里加上这几个
<!--网络 精确定位gps，权限不懂的Google或者看API-->
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />权限都加上了，看看我的activity
package*********
import***********
public class LocationActivity extends Activity {
private String TAG = "LocationActivity";
private LocationManager locationManager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
}
@Override
protected void onResume() {
super.onResume();
initData();//init
}
private void initData(){
if (!locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
Log.i(TAG,"gps close");
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(intent, 0);
return;
} else {
Log.i(TAG,"gps open");
}
String bestProvider = locationManager.getBestProvider(getCriteria(),true);
Location location = locationManager.getLastKnownLocation(bestProvider);
updateView(location);
/*
1000毫秒 0米偏移量，更新,定位方式我用的NETWORK_PROVIDER,
也可以用GPS_PROVIDER,只是gps在室内好像定不了
*/
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
1000, 0, locationListener);
}
private void updateGps(Location location) {
if (location != null) {
Log.i(TAG,"设备位置信息,经度："+String.valueOf(location.getLongitude())
+ "纬度：" + String.valueOf(location.getLatitude())
+ "海拔：" + String.valueOf(location.getAltitude())）；
} else {
Log.i(TAG,"暂时未获取到位置");
}
}
private Criteria getCriteria() {
Criteria criteria = new Criteria();
/*
设置定位精确度 Criteria.ACCURACY_COARSE比较粗略，
Criteria.ACCURACY_FINE则比较精细,此处注意，
如果想粗略的定位要去AndroidManifest.xml中加上粗略的权限，
*/
criteria.setAccuracy(Criteria.ACCURACY_FINE);
// 设置是否要求速度
criteria.setSpeedRequired(false);
// 设置是否允许运营商收费
criteria.setCostAllowed(false);
// 设置是否需要方位信息
criteria.setBearingRequired(false);
// 设置是否需要海拔信息
criteria.setAltitudeRequired(true);
// 设置对电源的需求
criteria.setPowerRequirement(Criteria.POWER_LOW);
return criteria;
}
private LocationListener locationListener = new LocationListener() {
/**
* 位置信息变化时触发
*/
public void onLocationChanged(Location location) {
updateGps(location);
}
/**
* GPS状态变化时触发
*/
public void onStatusChanged(String provider, int status, Bundle extras) {
switch (status) {
// GPS状态为可见时
case LocationProvider.AVAILABLE:
Log.i(TAG, "当前GPS状态为可见状态");
break;
// GPS状态为服务区外时
case LocationProvider.OUT_OF_SERVICE:
Log.i(TAG, "当前GPS状态为服务区外状态");
break;
// GPS状态为暂停服务时
case LocationProvider.TEMPORARILY_UNAVAILABLE:
Log.i(TAG, "当前GPS状态为暂停服务状态");
break;
}
}
/**
* GPS开启时触发
*/
public void onProviderEnabled(String provider) {
Location location = locationManager.getLastKnownLocation(provider);
updateGps(location);
}
/**
* GPS禁用时触发
*/
public void onProviderDisabled(String provider) {
updateGps(null);
}
};
private GpsStatus.Listener listener = new GpsStatus.Listener() {
@Override
public void onGpsStatusChanged(int event) {
switch (event) {
case GpsStatus.GPS_EVENT_FIRST_FIX:
Log.i(TAG, "第一次定位");
break;
case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
Log.i(TAG, "卫星状态改变");
GpsStatus gpsStatus = locationManager.getGpsStatus(null);
int maxSatellites = gpsStatus.getMaxSatellites();
Iterator<GpsSatellite> iters = gpsStatus.getSatellites()
.iterator();
int count = 0;
while (iters.hasNext() && count <= maxSatellites) {
GpsSatellite s = iters.next();
count++;
}
break;
case GpsStatus.GPS_EVENT_STARTED:
Log.i(TAG, "定位启动");
break;
case GpsStatus.GPS_EVENT_STOPPED:
Log.i(TAG, "定位结束");
break;
}
}
};
}复制到你类中，有需要import的全部导入即可，运行下查看是否可以获取gps，亲测三星是可以的，比较仓促，不足之处留言。
