如何显示启用位置对话框，如谷歌地图？
我使用最新版本的Google Play服务（7.0），并按照其指南中给出的步骤进行操作，我启用了如下的位置对话框，其中有一个“从不”button。 我的应用程序强制需要位置，所以我不想显示从不向用户，因为一旦用户点击“从不”，我无法再获取位置或请求位置。
哪里像Google Maps只有没有button，没有button，任何想法如何实现一样？

LocationSettingsRequest.Builder有一个方法setAlwaysShow(boolean show) 。 虽然文档表示目前没有任何操作 （更新2015-07-05：Google文档更新已经删除了这个措辞），但是设置了builder.setAlwaysShow(true); 将启用Google地图的行为： 
下面是使它工作的代码：
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()); 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; } } }); }

对于那些想要处理“是/否”button的人来说，我想对凯的答案加上一些修改。
在你的活动中声明这个常量
protected static final int REQUEST_CHECK_SETTINGS = 0x1;
调用onStart（）中的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; } }
奥拉出租车正在使用新发布的设置API来实现这一function。 根据新的API，用户不需要导航到设置页面来启用位置服务，从而实现相同的无缝集成。 请阅读下面的更多细节：

它的工作类似于谷歌地图？ 源代码

您也可以添加多个LocationRequests Builder来实现“使用GPS，Wi-Fi和移动networking进行定位”对话，而不是“使用GPS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());
