此代码与网络完美配合，但我需要做WiFi测试GPSwifi.so我想做检查GPS无线和网络两者。任何人都无法帮助如何在Android应用程序中完成这项工作。

此代码适用于Android网络基础，但我需要使用GPS wifi ..

你可以做一件事......只需在活动开始时自动启动你的WiFi
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
if (wifiManager != null) {
wifiManager.setWifiEnabled(true);
}
}
将权限放入清单文件中：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

这个怎么样：http://sourceforge.net/projects/libwlocate/
该库通过单一界面执行GPS和WLAN定位，易于使用。当然还有Android源和端口。
答案 2 :(得分：0)
如果你想先用先到先得，那么你可以为wifi和网络做两个独立的位置监听器。就像下面一样。
try
{
gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
}catch(Exception ex){
ex.printStackTrace();
}
//don't start listeners if no provider is enabled
if(!gps_enabled && !network_enabled)
return false;
if(gps_enabled)
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListenerGps);
if(network_enabled)
lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListenerNetwork);
然后你可以听两个听众jus
LocationListener locationListenerGps = new LocationListener() {
public void onLocationChanged(Location location) {
// timer1.cancel();
Log.d("from", "GPS");
locationResult.gotLocation(location);
lm.removeUpdates(this);
lm.removeUpdates(locationListenerNetwork);
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
};
LocationListener locationListenerNetwork = new LocationListener() {
public void onLocationChanged(Location location) {
// timer1.cancel();
Log.d("from", "NETWORK");
locationResult.gotLocation(location);
lm.removeUpdates(this);
lm.removeUpdates(locationListenerGps);
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
};
这就是你如何制作先到先得的位置监听器。希望这有帮助。

尝试此代码..它适用于 Network_Provider
protected void onCreate（Bundle savedInstanceState）{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
boolean answer;
answer=isOnline();
System.out.println(answer);
if(answer){
LocationManager L = (LocationManager) getSystemService(LOCATION_SERVICE);
if (L.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
gps_loc();
} else
{
showSettingsAlert();
}
}
else
{
Toast.makeText(getApplicationContext(), "Check your Internet Connection",Toast.LENGTH_SHORT).show();
}
}
public boolean isOnline（）{
ConnectivityManager cm =
(ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if (netInfo != null && netInfo.isConnectedOrConnecting()) {
return true;
}
return false;
}
public void showSettingsAlert(){

Intent I = new Intent(

startActivity(I);
Toast.makeText(getApplicationContext(),"Tick Use_wifi settings and click back button", Toast.LENGTH_LONG).show();
}
})
.setNegativeButton("No", null)
.show();
}
void gps_loc()
{
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// LocationListener ll = new mylocationlistener();
Location location=lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {
Log.d("LOCATION CHANGED", location.getLatitude() + "");
Log.d("LOCATION CHANGED", location.getLongitude() + "");
Toast.makeText(getApplicationContext(),"", Toast.LENGTH_SHORT).show();
double lat=location.getLatitude();
double lng=location.getLongitude();
List<Address> addresses = null;
try {

} catch (IOException e) {

}
Address addr= addresses.get(0);
