私の英語の最初の申し訳ありませんが、私はよく理解していますが、大丈夫ですか?

緯度と経度をbdに保存するLocationServiceが1つあります。彼はうまく機能しますが、LocationListenerが変更されたときに、私の意図に情報を送信したいと思います。EditTextに入れるインテントに文字列を送信したいと思います。

サービスのコード:

public class LocalizadorService extends Service{

private LocationManager locManager;
private LocationListener locListener;
private EjercicioBD baseDatos = EjercicioBD.getEjercicioBD(this);

@Override
public IBinder onBind(Intent arg0) {
    return null;
}

@Override
public void onCreate() {
    super.onCreate();
}

@Override
public void onStart(Intent intent, int startId) {
    encontrarGPS();
    super.onStart(intent, startId);
}

@Override
public void onDestroy() {
    locManager.removeUpdates(locListener);
    super.onDestroy();
}

private void encontrarGPS() {
    //Obtenemos una referencia al LocationManager
    locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);

    if(locManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
        locListener = new LocationListener(){
            public void onLocationChanged(Location arg0) {
                if (arg0 != null) {
                    setCurrentLocation(arg0);
                }
            }

            public void onProviderDisabled(String arg0) {
                noGPS();
                Toast.makeText(LocalizadorService.this, "El GPS ha sido desactivado, activelo", Toast.LENGTH_SHORT).show();
            }
            public void onProviderEnabled(String arg0) {
                         **HERE WANT TO SEND A STRING TO MY INTENT**
            public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
                         **HERE WANT TO SEND A STRING TO MY INTENT**
                    }
        };
        locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 7000, 0, locListener);
    }
    else{
        Toast.makeText(LocalizadorService.this, "El GPS no esta activado, por favor activelo para empezar", Toast.LENGTH_SHORT).show();
        noGPS();
    }
}

private void noGPS(){
    Intent intent = new Intent( android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);
}
private void setCurrentLocation(Location arg0){
    if(arg0 != null)
        baseDatos.insertarTablas(arg0.getLatitude(), arg0.getLongitude(), arg0.getSpeed());
}
}

どのようにできるのか?

みんなありがとう。

私は LocationListener でこれを行います:

public void onProviderDisabled(String arg0) {
                noGPS();
                Toast.makeText(LocalizadorService.this, "El GPS ha sido desactivado, activelo", Toast.LENGTH_SHORT).show();
                intent.setAction(EjercicioBroad.MESSAGE);
                intent.addCategory(Intent.CATEGORY_DEFAULT);
                intent.putExtra("prueba", "PROBANDO");
                sendBroadcast(intent);
            }

そして、これは内部クラスでの私の活動です:

public class EjercicioIniciar extends Activity {

private EditText nombreRuta;
private Button empezar,terminar,aceptar,cancelar;
private EjercicioBD baseDatos;
private boolean rutaEmpezada;
private SharedPreferences misDatos;
private SharedPreferences.Editor editor;
private Chronometer cronometro;

private EditText info;
private StringBuilder builder = new StringBuilder();
private RadioButton andar,correr,bici,coche;

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

    baseDatos = EjercicioBD.getEjercicioBD(this);

    empezar = (Button)findViewById(R.id.empezar);

    terminar = (Button)findViewById(R.id.terminar);

    cronometro = (Chronometer)findViewById(R.id.cronometro);
    cronometro.setTextColor(Color.BLUE);

    info = (EditText)findViewById(R.id.editText1);
    info.setFocusable(false);
    info.setShadowLayer(2, 0, 0, Color.BLACK);

    String fontPath = "fonts/DS-DIGIT.ttf";
    Typeface tf = Typeface.createFromAsset(getAssets(), fontPath);
    cronometro.setTypeface(tf);

    misDatos = getApplicationContext().getSharedPreferences("misDatos", Context.MODE_PRIVATE);
    editor = misDatos.edit();
    rutaEmpezada = misDatos.getBoolean("rutaEmpezada", false);
}

@Override
protected void onStart() {
    super.onStart();
    empezar.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v) {
            if(!rutaEmpezada){
                final Dialog dialogo = new Dialog(EjercicioIniciar.this);
                dialogo.setContentView(R.layout.nombre_tabla);
                dialogo.setTitle("Nombre de la ruta");

                nombreRuta = (EditText)dialogo.findViewById(R.id.nombreRuta);

                aceptar = (Button)dialogo.findViewById(R.id.aceptar);
                aceptar.setOnClickListener(new OnClickListener(){
                    @Override
                    public void onClick(View v) {
                        int creada = baseDatos.crearTablas(nombreRuta.getText().toString().trim());

                        if(creada == 1){
                            Intent service = new Intent(EjercicioIniciar.this,LocalizadorService.class);
                            startService(service);

                            cronometro.setBase(SystemClock.elapsedRealtime());

                            Calendar calen = Calendar.getInstance();
                            String actual = ""+calen.get(Calendar.HOUR_OF_DAY)+":"+calen.get(Calendar.MINUTE)+":"+calen.get(Calendar.SECOND);
                            cronometro.start();

                            builder.append("Ha iniciado una ruta "+radioButton().toUpperCase()+", "+nombreRuta.getText().toString().toUpperCase()+" \n"+"A las "+actual+" \n");
                            info.setText(builder);

                            dialogo.dismiss();

                            rutaEmpezada = true;
                            editor.putBoolean("rutaEmpezada", true);
                            editor.commit();
                        }
                    }
                });

                cancelar = (Button)dialogo.findViewById(R.id.cancelar);
                cancelar.setOnClickListener(new OnClickListener(){
                    @Override
                    public void onClick(View v) {
                        dialogo.dismiss();
                    }
                });

                andar = (RadioButton)dialogo.findViewById(R.id.andar);

                bici = (RadioButton)dialogo.findViewById(R.id.bici);
                coche = (RadioButton)dialogo.findViewById(R.id.coche);

                dialogo.show();
            }else
                Toast.makeText(EjercicioIniciar.this, "Actualmente has iniciado una ruta", Toast.LENGTH_SHORT).show();
        }
    });
    terminar.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v) {
            if(rutaEmpezada){
                Intent service = new Intent(EjercicioIniciar.this,LocalizadorService.class);
                stopService(service);

                Calendar calen = Calendar.getInstance();
                String actual = ""+calen.get(Calendar.HOUR_OF_DAY)+":"+calen.get(Calendar.MINUTE)+":"+calen.get(Calendar.SECOND);
                builder.append("Fin de su ruta a las "+actual+"\n");
                cronometro.stop();
                builder.append("Duración de la ruta, "+cronometro.getText());
                info.setText(builder);
                cronometro.setBase(SystemClock.elapsedRealtime());

}

private String radioButton(){

        return andar.getText().toString();

    else
        return "de alguna manera";
}

public class EjercicioBroad extends BroadcastReceiver{
    public static final String MESSAGE = "MESSAGE STRING";
    @Override
    public void onReceive(Context arg0, Intent arg1) {
        info.setText(arg1.getStringExtra("prueba"));
    }
}

}

動作しません。ediText は変更されません。全てに感謝

たとえば、のandメソッドで使用できますBroadcastReceiverActivitysentBroadcastService

BroadCastReceiver を使用する必要があります。サービスクラスで Service の代わりに IntentService を拡張する必要があります

このサンプル コードをアクティビティ クラスに挿入します。

   public class YourClass{
     private IntentFilter yourfilter;
     private ResponseReceiver yourreceiver;


     Override
     public void onCreate(Bundle savedInstanceState) {

      yourfilter = new IntentFilter(ResponseReceiver.MESSAGE);
      yourfilter.addCategory(Intent.CATEGORY_DEFAULT);
      yourreceiver = new ResponseReceiver();
      registerReceiver(yourreceiver, yourfilter);

     Intent i = new Intent(YourActivity.this, YourService.class);
     startService(i);
     }

    public class ResponseReceiver extends BroadcastReceiver {
       public static final String MESSAGE = "MESSAGE STRING";

       @Override
       public void onReceive(Context context, Intent intent) {
       yourEditText.setValue(intent.getStringExtra(YourKey);

      }
    }

場所が変わるたびに、このコードをサービスクラスに入れます

    public class YourService extends IntentService {

    Intent broadcastIntent = new Intent();
    broadcastIntent.setAction(ResponseReceiver.MESSAGE);
    broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT);
    broadcastIntent.putExtra(yourkey, yourvalue);
    sendBroadcast(broadcastIntent);
