窗口小部件的onReceive犯规增量INT

问题描述

我目前了解的Andr​​oid部件。我想增加计数器的值，但是当我点击小窗口从0增加它1并停止增加它。我的 onRecieve 方法做工精细。
这里是我的code：

公共静态了checkdate了checkdate;
公共静态EVENTLIST EVENTLIST;公共静态字符串EVENT_CLICK =EventClick;
公共弦乐味精;公共RemoteViews rviews;
公共AppWidgetManager经理;
公共语境cntxt;
公众意向intnt;
公众诠释[] IDS;公众诠释计数= 0;公共无效的onUpdate（上下文的背景下，AppWidgetManager appWidgetManager，INT [] appWidgetIds）{
    super.onUpdate（背景下，appWidgetManager，appWidgetIds）;    了checkdate =新了checkdate（）;
    EVENTLIST =新EVENTLIST（）;    经理= appWidgetManager;
    RemoteViews意见=新的RemoteViews（context.getPackageName（），R.layout.widget_layout）;
    IDS = appWidgetIds;    意向意图=新意图（背景下，DayWidget.class）;
    intent.setAction（EVENT_CLICK）;
    intent.putExtra（味精，变）;    的PendingIntent actionPendingIntent = PendingIntent.getBroadcast（上下文，0，意图，0）;    views.setOnClickPendingIntent（R.id.Event，actionPendingIntent）;    CheckDate.Check（）;    views.setTextViewText（R.id.Today，CheckDate.Today）;
    views.setTextViewText（R.id.Event，将String.valueOf（柜））;    manager.updateAppWidget（IDS，意见）;
}公共无效UpdateWidget（）{
    捆绑额外= intnt.getExtras（）;
    如果（临时演员！= NULL）{
        AppWidgetManager appWidgetManager = AppWidgetManager.getInstance（cntxt）;
        组件名AppWidget =新单元名（cntxt.getPackageName（），DayWidget.class.getName（））;
        INT [] = appWidgetIds appWidgetManager.getAppWidgetIds（AppWidget）;        rviews =新RemoteViews（AppWidget.getPackageName（），R.layout.widget_layout）;
        反++;
        rviews.setTextViewText（R.id.Event，将String.valueOf（柜））;        appWidgetManager.updateAppWidget（appWidgetIds，rviews）;
    }
}公共无效的onReceive（上下文的背景下，意图意图）{
    intnt =意图;
    cntxt =背景;    如果（EVENT_CLICK.equals（intent.getAction（）））{
        尝试{
            味精= intent.getStringExtra（味精）;
        }赶上（NullPointerException异常五）{
            e.printStackTrace（）;
        }
        UpdateWidget（）;
        吐司面包= Toast.makeText（cntxt，onclick事件，Toast.LENGTH_LONG）;
        toast.show（）;
    }
    super.onReceive（背景下，意图）;
}


解决方案

让你的公众诠释计数= 0; 静态是公共静态INT计数= 0;
或将其保存在共享preference

I am currently learning about widgets in Android. I want to increment counter value, but when I click on widget it increment it from 0 to 1 and stops to increase it. My onRecieve method work fine. Here is my code:

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);
}

解决方案

make your public int counter = 0; static to be public static int counter = 0;Or save it on shared preference
