窗口小部件的onReceive犯規增量INT

Question

我目前瞭解的Android部件。我想增加計數器值，但是當我點擊小部件時，它將從0增加到1，然後停下來增加它。我的onRecieve方法工作正常。 這裏是我的代碼：

public static CheckDate CheckDate; 
public static EventList EventList; 

public static String EVENT_CLICK = "EventClick"; 
public String msg; 

public RemoteViews rviews; 
public AppWidgetManager manager; 
public Context cntxt; 
public Intent intnt; 
public int[] ids; 

public int counter = 0; 

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds){ 
    super.onUpdate(context, appWidgetManager, appWidgetIds); 

    CheckDate = new CheckDate(); 
    EventList = new EventList(); 

    manager = appWidgetManager; 
    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout); 
    ids = appWidgetIds; 

    Intent intent = new Intent(context, DayWidget.class); 
    intent.setAction(EVENT_CLICK); 
    intent.putExtra("msg", "change"); 

    PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0); 

    views.setOnClickPendingIntent(R.id.Event, actionPendingIntent); 

    CheckDate.Check(); 

    views.setTextViewText(R.id.Today, CheckDate.Today); 
    views.setTextViewText(R.id.Event, String.valueOf(counter)); 

    manager.updateAppWidget(ids, views); 
} 

public void UpdateWidget(){ 
    Bundle extras = intnt.getExtras(); 
    if(extras!=null) { 
     AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(cntxt); 
     ComponentName AppWidget = new ComponentName(cntxt.getPackageName(), DayWidget.class.getName()); 
     int[] appWidgetIds = appWidgetManager.getAppWidgetIds(AppWidget); 

     rviews = new RemoteViews(AppWidget.getPackageName(), R.layout.widget_layout); 
     counter ++; 
     rviews.setTextViewText(R.id.Event, String.valueOf(counter)); 

     appWidgetManager.updateAppWidget(appWidgetIds, rviews); 
    } 
} 

public void onReceive(Context context, Intent intent){ 
    intnt = intent; 
    cntxt = context; 

    if(EVENT_CLICK.equals(intent.getAction())){ 
     try{ 
      msg = intent.getStringExtra("msg"); 
     }catch(NullPointerException e){ 
      e.printStackTrace(); 
     } 
     UpdateWidget(); 
     Toast toast = Toast.makeText(cntxt, "OnClick", Toast.LENGTH_LONG); 
     toast.show(); 
    } 
    super.onReceive(context, intent); 
} 

Answer 1

讓你public int counter = 0;static是public static int counter = 0; 或將其保存在共享偏好
