アプリケーションでAndroidデフォルトのGPS ON-OFFダイアログを使用する

私たちのアプリケーションでは、AndroidデフォルトのGPSダイアログを統合します。GPSがオフで、Googleマップアプリで現在地ボタンを押すと表示される同じダイアログです。また、統合したいダイアログ。

  1. 「いいえ」オプションをクリックすると、ダイアログが閉じます。
  2. 「はい」オプションをクリックすると、デバイスのGPSが直接アクティブになります。

以下のOLAアプリで表示されるダイアログ（Android L）：

以下のOLAアプリで表示されるダイアログ（Android KIT_KAT）：

以下のGoogleマップ用に表示されるダイアログ（Android L）：
enter image description here

私たちの既存の実装では、GPSがオフの場合、アプリケーションをデバイスのデフォルトのロケーション設定画面にリダイレクトし、そこからロケーションをオンにすることができます。

答えを楽しみにしています。前もって感謝します。

Google Playサービスの最新バージョンを使用する必要があります。最新バージョンでは、GPSを取得するために必要なすべてのものをアクティブにするダイアログが1つあります。

Android Developer Play Serviceのドキュメントから、

位置設定-FusedLocationProviderApiは複数のセンサーを組み合わせて最適な位置を提供しますが、アプリが受信する位置の精度は、デバイスで有効になっている設定（GPS、wifi、機内モードなど）に大きく依存します。新しいSettingsApiクラスを使用すると、ユーザーがアプリを終了せずに設定を変更するためのワンタッチコントロールを表示する場所設定ダイアログを表示できます。

Link は、Play Serviceバージョンのドキュメントを示します。バージョン7.0では、この新しいプロンプトが導入されました。

ステップバイステップ

ステップ1でGPSデバイスがサポートされているかどうかを確認します

ステップ2 hasGPSDevice true check Marshmallow Permimssion

ステップ3 Marshmallow Permimssion true check Location on already not

ステップ4位置がCALL Gpsトラッカーの場合、緯度経度をフェッチします

ステップ5ロケーションがoFfの場合、CAll Location DialogはGoogleマップと同じ
