我希望通过Wifi获取位置并在谷歌地图中工作,这对我不起作用,但Gps没问题,也没问题.
我的代码：
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
if (locationManager != null) {
boolean gpsIsEnabled = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
boolean networkIsEnabled = locationManager
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (gpsIsEnabled) {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,5000L,10F,(android.location.LocationListener) this);
} else if (networkIsEnabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,(android.location.LocationListener) this);
} else {
// Show an error dialog that GPS is disabled...
}
} else {
// Show some generic error dialog because something must have gone
// wrong with location manager.
}
AndroidManifest：
<uses-library android:name="com.google.android.maps" /> <Meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="AIzaSyB4C_zHeHYMTWqW4_Wpin-5jLF9S54KDSQ" /> </application> <permission android:name="com.karyan.karyanmap.permission.MAPS_RECEIVE" android:protectionLevel="signature" /> <uses-permission android:name="com.karyan.karyanmap.permission.MAPS_RECEIVE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE" /> <uses-feature android:name="android.hardware.wifi" android:required="true"/> <uses-feature android:name="android.hardware.camera" android:required="false" > </uses-feature> <uses-feature android:glEsVersion="0x00020000" android:required="true" />
当wifi连接到Intenet时,Newtork_Provider为null.如何解决问题
谢谢..
解决方法
比方说,我可以为GPS_PROVIDER和NETWORK_PROVIDER(或PASSIVE_PROVIDER)设置“请求位置更新”到相同的函数调用,如下所示：
// SETUP Location Manager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,this); locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,this); locationManager.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER,this);
在这种情况下,我只获得GPS数据.
