我正在开发一个应用程序在Android操作系统。我不知道如何检查位置服务是否启用。
我需要一个方法,如果它们被启用,返回“true”,如果没有“false”(所以在最后一种情况下,我可以显示一个对话框来启用它们)。

根据上面的答案,在API 23中,你需要添加“危险”权限检查以及检查系统本身:
public static boolean isLocationServicesAvailable(Context context) {
int locationMode = 0;
String locationProviders;
boolean isAvailable = false;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
try {
locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);
} catch (Settings.SettingNotFoundException e) {
e.printStackTrace();
}
isAvailable = (locationMode != Settings.Secure.LOCATION_MODE_OFF);
} else {
locationProviders = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
isAvailable = !TextUtils.isEmpty(locationProviders);
}
boolean coarsePermissionCheck = (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED);
boolean finePermissionCheck = (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
return isAvailable && (coarsePermissionCheck || finePermissionCheck);
}

boolean finePermissionCheck = (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
return isAvailable && (coarsePermissionCheck || finePermissionCheck);
}
是的,你可以检查以下是代码:
public boolean isGPSEnabled(Context mContext)
{
LocationManager lm = (LocationManager)
mContext.getSystemService(Context.LOCATION_SERVICE);
return lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
}
在manifest文件中的权限下:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
迁移到AndroidX并使用
implementation 'androidx.appcompat:appcompat:1.3.0'
并使用LocationManagerCompat
在Java中
private boolean isLocationEnabled(Context context) {
LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
return LocationManagerCompat.isLocationEnabled(locationManager);
}
在Kotlin
private fun isLocationEnabled(context: Context): Boolean {
val locationManager = context.getSystemService(Context.LOCATION_SERVICE) as LocationManager
return LocationManagerCompat.isLocationEnabled(locationManager)
}
You can also use extension function.
------------------------------------
fun Context.isLocationEnabled(): Boolean{
val locationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
return LocationManagerCompat.isLocationEnabled(locationManager)}
能用最简单的方法做吗
private boolean isLocationEnabled(Context context){
int mode =Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE,
Settings.Secure.LOCATION_MODE_OFF);
final boolean enabled = (mode != android.provider.Settings.Secure.LOCATION_MODE_OFF);
return enabled;
}
