OlaCabsのようにプログラムでGPSをオンにするAndroid app

私はアプリケーションに取り組んでおり、GPS位置情報を統合する必要があります。プログラムでGPSをオンにしたい。条件は次のとおりです。ユーザーを設定パネルに送信して有効にしたくない。強制的に有効にしたい、または単一のプロンプトが機能する（Ola Cabs Android app）と同様）。このサイトではこれについて多くの質問がありますが、誰もが次のような同様の機能を探しています。 Ola Cabsアプリ。それで、私たち全員が明確にできるように、このスレッドを開始しました。

これが私の100％動作するコードです。最初にこの依存関係compile 'com.google.Android.gms:play-services:9.2.1'をbuild.gradle（Module：app）に追加します。

その後、StartLocationAlert.Javaという名前のクラスを作成し、このコードをコピーしてこのファイルに貼り付けます

上記のクラスの使用法を以下に示します

また、AndroidManifest.xmlファイルに以下の権限を追加することを忘れないでください。そうしないと、これが正しく機能しない可能性があります

 <uses-permission Android:name="Android.permission.ACCESS_FINE_LOCATION" />
 <uses-permission Android:name="Android.permission.ACCESS_COARSE_LOCATION"/>

これがお役に立てば幸いです。

SettingsApiは非推奨であるため、開発者サイトにチェックインした後 ここ 。 Olaアプリと同じ結果を出すことができました。

以下のメソッドをActivityクラスに追加します

private void switchOnGPS() {
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(new LocationRequest().setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY));

    Task<LocationSettingsResponse> task = LocationServices.getSettingsClient(this).checkLocationSettings(builder.build());
    task.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() {
        @Override
        public void onComplete(@NonNull Task<LocationSettingsResponse> task) {
            try {
                LocationSettingsResponse response = task.getResult(ApiException.class);
            } catch (ApiException e) {
                switch (e.getStatusCode())
                {
                    case LocationSettingsStatusCodes.RESOLUTION_REQUIRED :
                        ResolvableApiException   resolvableApiException = (ResolvableApiException) e;
                        try {
                            resolvableApiException.startResolutionForResult(MainActivity.this,REQUEST_CHECK_SETTINGS);
                        } catch (IntentSender.SendIntentException e1) {
                            e1.printStackTrace();
                        }
                        break;

                        case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                            //open setting and switch on GPS manually
                            break;
                }
            }
        }
    });
    //Give permission to access GPS
    ActivityCompat.requestPermissions(this, new String[]{Android.Manifest.permission.ACCESS_FINE_LOCATION}, 11);
}

以下のように、アクティビティのonResumeメソッドで上記のメソッドを呼び出します

@Override
protected void onResume() {
    super.onResume();
    switchOnGPS();
}

マニフェストファイルにそれぞれのロケーション権限を追加します。

アニルーダの答えに基づいてライブラリを作成しました。

それを使用する方法の短いガイド：

  1. それをあなたに追加_build.gradle_ファイル：

    _compile 'net.alexandroid.utils:gps:1.6'_

  2. ImplementGpsStatusDetectorCallBackインターフェース。

  3. インターフェースメソッドの実装：onGpsSettingStatusおよびonGpsAlertCanceledByUser

  4. Createインスタンス変数：

    _private GpsStatusDetector mGpsStatusDetector;
_

  5. Instantiateit in onCreate()：

    _ mGpsStatusDetector = new GpsStatusDetector(this);
_

  6. 代わりに、ステータスを確認し、必要に応じてダイアログを表示する必要がありますadd：

    _mGpsStatusDetector.checkGpsStatus();
_

  7. OverrideonActivityResultそしてそこに追加します：

    _mGpsStatusDetector.checkOnActivityResult(requestCode, resultCode);
_

ライブラリの詳細： https://github.com/Pulimet/GpsDetector-Library

例：

_public class MainActivity extends AppCompatActivity implements GpsStatusDetector.GpsStatusDetectorCallBack {

    private GpsStatusDetector mGpsStatusDetector;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mGpsStatusDetector = new GpsStatusDetector(this);
        mGpsStatusDetector.checkLocationSettingStatus();
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        mGpsStatusDetector.checkOnActivityResult(requestCode, resultCode);
    }

    @Override
    public void onGpsSettingStatus(boolean enabled) {
        Log.d("TAG", "onGpsSettingStatus: " + enabled);
    }

    @Override
    public void onGpsAlertCanceledByUser() {
        Log.d("TAG", "onGpsAlertCanceledByUser");
    }
}

ここに私はユーザーにこのコードを持っています

private void turnGPSOn(){
    String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

    if(!provider.contains("gps")){ //if gps is disabled
        final Intent poke = new Intent();
        poke.setClassName("com.Android.settings", "com.Android.settings.widget.SettingsAppWidgetProvider"); 
        poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
        poke.setData(Uri.parse("3")); 
        sendBroadcast(poke);
    }
}

private void turnGPSOff(){
    String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

    if(provider.contains("gps")){ //if gps is enabled
        final Intent poke = new Intent();
        poke.setClassName("com.Android.settings", "com.Android.settings.widget.SettingsAppWidgetProvider");
        poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
        poke.setData(Uri.parse("3")); 
        sendBroadcast(poke);
    }
    }

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設定APIを使用しています。新しいAPIに従って、ユーザーは設定ページに移動して位置情報サービスを有効にする必要がなく、位置情報サービスをシームレスに統合できます。詳細については、以下をお読みください。
