Android:使用 Fused Location Provider 检查是不是启用了位置服务

【中文标题】Android:使用 Fused Location Provider 检查是不是启用了位置服务【英文标题】:Android: Check if Location Services Enabled using Fused Location ProviderAndroid:使用 Fused Location Provider 检查是否启用了位置服务 【发布时间】:2015-12-02 02:15:09 【问题描述】:根据 android 文档:
Google 位置服务 API,Google Play 服务的一部分, 提供了一个更强大的高级框架,可以自动 处理位置提供者、用户移动和位置准确性比
android.location
中的平台位置API。
但使用融合位置提供程序(来自 Google Play 服务中的位置 API)我不知道如何检查用户是否启用或禁用了位置。
使用 old android.location
很容易:
locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
但我不想同时使用 Google Play Services 融合位置提供程序和 旧 android 位置。
如何检查用户是否使用 Fused Location Provider 启用了位置?
提前致谢。

嗨,你能把你的实现发布为答案吗? 【参考方案1】:This android developer training tutorial could help - 基本情况如下:
在 Activity onCreate() 中运行的代码:
// Create an instance of GoogleAPIClient.
if (mGoogleApiClient == null)
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mGoogleApiClient.connect();
LocationRequest mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(10000);
mLocationRequest.setFastestInterval(5000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(mLocationRequest);
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>()
@Override
public void onResult(LocationSettingsResult locationSettingsResult)
final Status status = locationSettingsResult.getStatus();
final LocationSettingsStates LS_state = locationSettingsResult.getLocationSettingsStates();
switch (status.getStatusCode())
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can initialize location
// requests here.
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the user
// a dialog.
try
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(LocationByGPS.this, REQUEST_CHECK_SETTINGS);
catch (IntentSender.SendIntentException e)
// Ignore the error.
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way to fix the
// settings so we won't show the dialog.
break;
);
覆盖此方法:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
switch (requestCode)
case REQUEST_CHECK_SETTINGS:
switch (resultCode)
case Activity.RESULT_OK:
// All required changes were successfully made
GetUserLocation();//FINALLY YOUR OWN METHOD TO GET YOUR USER LOCATION HERE
break;
case Activity.RESULT_CANCELED:
// The user was asked to change settings, but chose not to
break;
default:
break;
break;
记得在你的课堂上实现这些:
public class MyClass extends AppCompatActivity implements
ActivityCompat.OnRequestPermissionsResultCallback,
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener
protected static final int REQUEST_CHECK_SETTINGS = 0x1;
/*
your code i.e. with the above code etc....
*/
Good explanation here in this Google developer link.
干杯!

我已经通过添加代码和另一个有用的链接来编辑我的答案。 看起来不错 - 我做了一些清理工作并修复了您的链接,但除此之外,这是一个可靠的答案。感谢您的建议,祝您好运! LocationByGPS.this 在哪里? 你甚至修复了官方 Android 开发者教程中的几个错误,太棒了。 @NabeelK 这是外部类,可能是您的 SomethingActivity 类。见官方教程。【参考方案2】:请参阅SettingsApi:检查您的位置请求,然后确保根据应用的位置需求正确配置设备的系统设置。

我在这里实现了 SettingsClient :github.com/askfortricks/FusedLocationProviderClient 因为现在不推荐使用 SettingsApi。【参考方案3】:2020 年现在
最新、最好、最短的方法是
public boolean isLocationEnabled()
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P)
// This is new method provided in API 28
LocationManager lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
return lm.isLocationEnabled();
else
// This is Deprecated in API 28
int mode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE,
Settings.Secure.LOCATION_MODE_OFF);
return (mode != Settings.Secure.LOCATION_MODE_OFF);

如何在不将用户重定向到配置的情况下启用 gps?我的意思是,当用户点击“确定”按钮时,会弹出一个 alertDialog 或snackBar 来启用 GPS。LocationManagerCompat.isLocationEnabled(context.getSystemService(Context.LOCATION_SERVICE) as LocationManager)
所以你不必检查 SDK 版本。【参考方案4】:
你也可以这样检查:
LocationManager service = (LocationManager) getSystemService(LOCATION_SERVICE);
boolean isEnabled = service.isProviderEnabled(LocationManager.GPS_PROVIDER);
【讨论】:
【参考方案5】:如果使用 FusedLocationProviderClient, 首先我们需要检查设备中是否启用了位置。
private fun isLocationEnabled(): Boolean
val activity: Activity? = this.activity
val lm = activity?.getSystemService(Context.LOCATION_SERVICE) as? LocationManager
if (lm != null)
val enabled = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P)
lm.isLocationEnabled
else
lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER)
|| lm.isProviderEnabled(LocationManager.GPS_PROVIDER)
Log.d(TAG, "isLocationServiceEnabled", enabled)
return enabled
return false
然后,检查 LocationSettings。
val request = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
val settingRequest = LocationSettingsRequest.Builder()
.addLocationRequest(request)
.build()
// check Location settings for the request
LocationServices.getSettingsClient(context)
.checkLocationSettings(settingRequest)
.addOnSuccessListener
// OK!!
// fusedLocationProviderClient.requestLocationUpdates
.addOnFailureListener exception ->
if (exception is ResolvableApiException)
try
exception.startResolutionForResult(activity, RC_LOCATION_SETTINGS)
catch (ex: IntentSender.SendIntentException)
// ignore
else
// handle other errors
showFusedDisabledDialog()
