LocationSettingsRequest.Builder有一个方法setAlwaysShow(boolean show)。调用builder.setAlwaysShow(true);将启用Google Maps行为，尽管文档指出它目前没有做任何事情（已于2015年7月5日更新：更新的Google文档已删除此措辞）：
以下是使其工作的代码：
if (googleApiClient == null) {
googleApiClient = new GoogleApiClient.Builder(getActivity())
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
googleApiClient.connect();
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(30 * 1000);
locationRequest.setFastestInterval(5 * 1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
//**************************
builder.setAlwaysShow(true); //this is the key ingredient
//**************************
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
final LocationSettingsStates state = result.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(
getActivity(), 1000);
} 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;
}
}
});
}
有关Kotlin，请参见此处: https://dev59.com/XF0a5IYBdhLWcg3w6sZk#61868985
RESOLUTION_REQUIRED。然后一旦我接受并启用位置，它就会触发SUCCESS，并完全跳过onActivityResult()。按下“否”或返回键会使对话框消失一秒钟，然后重新加载并再次触发RESOLUTION_REQUIRED。摆脱对话框的唯一方法是接受或关闭并重新打开应用程序。 - pez对于那些想要处理“是/否”按钮的人，我想在Kai的答案上增加一些更改。
在您的活动中声明此常量：
protected static final int REQUEST_CHECK_SETTINGS = 0x1;
在您的 onStart() 中调用 settingsrequest()。
public void settingsrequest()
{
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(30 * 1000);
locationRequest.setFastestInterval(5 * 1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
builder.setAlwaysShow(true); //this is the key ingredient
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
final LocationSettingsStates state = result.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(MainActivity.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;
}
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
// Check for the integer request code originally supplied to startResolutionForResult().
case REQUEST_CHECK_SETTINGS:
switch (resultCode) {
case Activity.RESULT_OK:
startLocationUpdates();
break;
case Activity.RESULT_CANCELED:
settingsrequest();//keep asking if imp or do whatever
break;
}
break;
}
}
LocationServices.SettingsApi已经被弃用，现在我们使用SettingsClient
LocationRequest mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(10);
mLocationRequest.setSmallestDisplacement(10);
mLocationRequest.setFastestInterval(10);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationSettingsRequest.Builder builder = new
LocationSettingsRequest.Builder();
builder.addLocationRequest(mLocationRequest);
然后检查当前位置设置是否满足要求。 创建 LocationSettingsResponse 任务：
Task<LocationSettingsResponse> task=LocationServices.getSettingsClient(this).checkLocationSettings(builder.build());
task.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() {
@Override
public void onComplete(Task<LocationSettingsResponse> task) {
try {
LocationSettingsResponse response = task.getResult(ApiException.class);
// All location settings are satisfied. The client can initialize location
// requests here.
} catch (ApiException exception) {
switch (exception.getStatusCode()) {
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the
// user a dialog.
try {
// Cast to a resolvable exception.
ResolvableApiException resolvable = (ResolvableApiException) exception;
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
resolvable.startResolutionForResult(
HomeActivity.this,
101);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
} catch (ClassCastException e) {
// Ignore, should be an impossible 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;
}
}
}
});
已添加 onActivityResult
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
switch (requestCode) {
case 101:
switch (resultCode) {
case Activity.RESULT_OK:
// All required changes were successfully made
Toast.makeText(HomeActivity.this,states.isLocationPresent()+"",Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
// The user was asked to change settings, but chose not to
Toast.makeText(HomeActivity.this,"Canceled",Toast.LENGTH_SHORT).show();
break;
default:
break;
}
break;
}
}

GoogleApiClient已被弃用。Kotlin中的新实现方法如下。
依赖项
// Google Maps Location Services
implementation 'com.google.android.gms:play-services-location:17.1.0'
implementation 'com.google.android.gms:play-services-maps:17.0.0'
代码
val locationRequest = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(30 * 1000)
.setFastestInterval(5 * 1000)
val builder = LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest)
.setAlwaysShow(true)
val pendingResult = LocationServices
.getSettingsClient(activity)
.checkLocationSettings(builder.build())
pendingResult.addOnCompleteListener { task ->
if (task.isSuccessful.not()) {
task.exception?.let {
if (it is ApiException && it.statusCode == LocationSettingsStatusCodes.RESOLUTION_REQUIRED) {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
(it as ResolvableApiException).startResolutionForResult(activity,
MainActivity.REQUEST_CODE_LOCATION)
}
}
}
}
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(createLocationRequest(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY))
.addLocationRequest(createLocationRequest(LocationRequest.PRIORITY_HIGH_ACCURACY))
.setAlwaysShow(true);
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
这是我的 Kotlin 示例 -
private fun enableLocation() {
val locationRequest = LocationRequest.create()
locationRequest.apply {
priority =LocationRequest.PRIORITY_HIGH_ACCURACY
interval = 30 * 1000.toLong()
fastestInterval = 5 * 1000.toLong()
}
val builder = LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest)
builder.setAlwaysShow(true)
val result=
LocationServices.getSettingsClient(requireContext()).checkLocationSettings(builder.build())
result.addOnCompleteListener {
try {
val response: LocationSettingsResponse = it.getResult(ApiException::class.java)
println("location>>>>>>> ${response.locationSettingsStates.isGpsPresent}")
if(response.locationSettingsStates.isGpsPresent)
//do something
}catch (e: ApiException){
when (e.statusCode) {
LocationSettingsStatusCodes.RESOLUTION_REQUIRED -> try {
val intentSenderRequest =
IntentSenderRequest.Builder(e.status.resolution).build()
launcher.launch(intentSenderRequest)
} catch (e: IntentSender.SendIntentException) {
}
}
}
}
}
使用以下的 getResult 方法
private var launcher= registerForActivityResult(ActivityResultContracts.StartIntentSenderForResult()){ result->
if (result.resultCode == Activity.RESULT_OK) {
Log.d(TAG, "OK")
} else {
Log.d(TAG, "CANCEL")
requireContext().toast("Please Accept Location enable for use this App.")
}
}
