我使用最新版本的 Google Play 服务 (7.0) 并按照他们指南中给出的步骤操作，并启用了如下所示的位置对话框，其中有一个“从不”按钮。我的应用强制需要位置，所以我不想向用户显示“从不”，因为一旦用户点击“从不”，我就无法再次获取位置或请求位置。
由于 Google 地图只有 yes 和 no 按钮而没有 never 按钮，知道如何实现相同的功能吗？

locationRequest.apply {

LocationSettingsRequest.Builder 有一个方法setAlwaysShow(boolean show)。 虽然文档表明它目前什么都不做（2015 年 7 月 5 日更新：更新的 Google 文档已删除此措辞），但设置 builder.setAlwaysShow(true); 将启用 Google 地图行为：
这是让它工作的代码：
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());

RESOLUTION_REQUIRED。然后，一旦我接受并启用位置，它会点击SUCCESS，并完全跳过onActivityResult()。按No 或返回会使对话框消失一秒钟，然后重新加载并再次点击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。
launchMode 不能设置为singleInstance，否则这将不起作用。该对话框将永远不会出现，onActivityResult 将被自动调用。在AndroidManifest 中的活动没有android:launchMode="singleInstance"。 3 小时后我学会了这个方法

GoogleApiClient 已弃用。用什么？
您还可以为 Builder 添加多个 LocationRequest 以实现“使用 GPS、Wi-Fi 和移动网络进行定位”对话框，而不是仅“使用 GPS 进行定位”
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());

LocationServices.SettingsApi 现已弃用，因此我们使用 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。 创建 LocationSettingsResponse 任务：
Task<LocationSettingsResponse> task=LocationServices.getSettingsClient(this).checkLocationSettings(builder.build());
然后添加监听器
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.

final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
switch (requestCode) {
case 101:
switch (resultCode) {
case Activity.RESULT_OK:
