Googleマップのように位置情報を有効にするダイアログを表示する方法
私は最新版のGoogle Play Services（7.0）を使い、彼らのガイドに書かれている手順に従った。そして私は以下のような位置ダイアログを有効にした。私のアプリは強制的に位置情報を必要とするので、私は絶対にユーザーに見せたくない。なぜなら、ユーザーが「絶対に」をクリックすると、位置情報を取得したり、位置情報を要求したりできないからだ。
グーグルマップは決してボタンなしではいといいえボタンしか持っていないので、どこで同じことを達成するためのアイデアがありますか？

LocationSettingsRequest.Builder メソッドsetAlwaysShow(boolean show)があります。 文書はそれが現在何もしていないことを示しているが（更新された2015-07-05：更新されたGoogleドキュメントはこの表現を削除しました）、builder.setAlwaysShow(true);を設定することはGoogleマップの振る舞いを可能にするでしょう： 
これがうまくいったコードです。
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;
}
}
}); }
はい/いいえボタンの処理を探している人のために、kaiの答えにいくつかの変更を加えたいと思います。
あなたの活動の中でこの定数を宣言する
protected static final int REQUEST_CHECK_SETTINGS = 0x1;
onStart（）でsettingsrequest()を呼び出します。
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;
}
}
その動作はグーグルマップに似ていますか？

LocationServices.SettingsApiは現在廃止されているので、SettingsClientを使用します
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);
次に、現在地の設定が満たされているかどうかを確認してください。 LocationSettingsResponseタスクを作成します。
Task<LocationSettingsResponse> task=LocationServices.getSettingsClient(this).checkLocationSettings(builder.build());
それからリスナーを追加します
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;
}
}
}
});
OnActivityResultを追加しました
@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;
}
}

Ola Cabsは、この機能を実現するために新しくリリースされたSettings APIを使用しています。新しいAPIでは、ロケーションサービスを有効にしてシームレスに統合できるようにするために、設定ページに移動する必要はありません。詳細については以下をお読みください。
https://developers.google.com/Android/reference/com/google/Android/gms/location/SettingsApi
また、「位置情報にGPSを使用」の代わりに「位置情報にGPS、Wi-Fiおよびモバイルネットワークを使用する」ダイアログを実現するために、BuilderにLocationRequestをいくつか追加することもできます。
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());
