Android - update widget text

Question

Hi, i have 2 questions about widgets update

• I have 2 buttons and i need to change one button text when i press the other one, how can i do this?

• The first time i open the widget it calls the onUpdate method, but it never calls it again. I need to update the widget every 2 seconds and i have this line in the xml.

  android:updatePeriodMillis="2000"

Do i need a service or should it works just with the updatePeriodMillis tag?

• onUpdate method

  RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.newswidget);
  
  
  Intent intent = new Intent(context, DetalleConsulta.class);
  intent.putExtra(DetalleConsulta.CONSULTA_ID_NAME, "3");
  PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
  views.setOnClickPendingIntent(R.id.btNews, pendingIntent);
  
  
  /* Inicializa variables para llamar el controlador */
  this.imei = ((TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId();
  this.controlador = new Controlador(this.imei);
  
  
  try {
      this.respuestas = this.controlador.recuperarNuevasRespuestas();
  
  
  if(this.respuestas != null && this.respuestas.size() > 0){
      Iterator<Consulta> iterRespuestas = this.respuestas.iterator();
      views.setTextViewText(R.id.btNews, ((Consulta)iterRespuestas.next()).getRespuesta());
  }
  
  
  } catch (PersistenciaException e) {
      //TODO manejar error
  }
  
  
  appWidgetManager.updateAppWidget(appWidgetIds, views);
  

thx a lot!!!

Answer 1

hi,

• about the first question i found a great example about handle widget events:

Handling User Interaction with Android App Widgets

• about the second one i was reading on the web and i found that in android 1.6 the minimun time to update the widget is 30 min.

I tried it and it works.

i hope this help others!!!

to update the text from another button...

 final    Button btn1 = (Button) this.findViewById(R.id.Button01);
   final Button btn2 = (Button) this.findViewById(R.id.Button02);

   btn1.setOnClickListener(new OnClickListener() {                      
            @Override
            public void onClick(View v) {
                btn2.setText("Button1 changed your text!");
            }           
        });
