私はこのgpsメソッドを手に入れました：

        globalconstant.db.setVersion(1);

        globalconstant.db.execSQL(gps);

        Log.d("FESTIVALE :: ", "Frissítési idő: "
                + globalconstant.gps_update_value);
        float f = Float.valueOf(globalconstant.gps_update_value.trim())
                .floatValue();

                LocationManager.GPS_PROVIDER, (long) update, 5f,
                globalconstant.mlocListener);

        // if(Global.getInstance().currentGPSLocation != null){

衛星に接続されるまで、簡単なローダーダイアログを作成したいと思います。どうすればそれを管理できますか？このメソッドが呼び出される前に、最初に衛星に接続されていることを確認するにはどうすればよいですか？あなたの答えをありがとう！

これを実装する必要がありますGpsStatus.Listener。

例えば、

public class MyActivity extends Activity implements GpsStatus.Listener
{
         ...
         ...
         ...
         // add listener into locationManager
        locationManager.addGpsStatusListener(this);

       @Override
       public void onGpsStatusChanged(int) 
       {

          switch (event) 
         {
            case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
            break;
            case GpsStatus.GPS_EVENT_FIRST_FIX:   // this means you  found GPS Co-ordinates                          
            break;
            case GpsStatus.GPS_EVENT_STARTED:
            break;
            case GpsStatus.GPS_EVENT_STOPPED:
            break;
          }
       }
}

ダイアログをポップアップし、場所の更新を要求し、実際に場所の更新を取得したときにダイアログを閉じることができます。

Activity実装してくださいGpsStatus.Listener

次に使用します：

public void onChanged(int event) {
        switch (event) {
            case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
                break;
            case GpsStatus.GPS_EVENT_FIRST_FIX:                              
                break;
            case GpsStatus.GPS_EVENT_STARTED:
                break;
            case GpsStatus.GPS_EVENT_STOPPED:
                break;
        }
    }

GpsStatus.GPS_EVENT_FIRST_FIXは、GPSシステムが起動してから最初の修正を受信したときに送信されるイベントです。
