为什么小部件不重新启动后工作？ [英] Why widget does not work after reboot?

问题描述

我有这个简单的小工具，当我点击它，它应该打开我的活动，它的工作原理，但它不会重新启动后正常工作。我必须删除，然后重新添加小部件到我的主屏幕，因为当我点击小窗口小部件不响应，不打开我的活动。那么问题出在哪里？

code：

 公共无效的OnUpdate（上下文的背景下，AppWidgetManager appWidgetManager，INT [] appWidgetIds）{
        最终诠释N = appWidgetIds.length;

        的for（int i = 0; I＆n种;我++）{
            INT appWidgetId = appWidgetIds [I]

            context.startService（新意图（背景下，WidgetService.class））;

            意向意图=新的意图（背景下，WidgetDialog.class）;
            PendingIntent pendingIntent = PendingIntent.getActivity（上下文，0，意图，0）;

            RemoteViews意见=新RemoteViews（context.getPackageName（），R.layout.widget）;
            views.setOnClickPendingIntent（R.id.layout_widget，pendingIntent）;

            appWidgetManager.updateAppWidget（appWidgetId，意见）;
        }
    }

    @覆盖
    公共无效onEnabled（上下文的背景下）{
        context.startService（新意图（背景下，WidgetService.class））;
    }

    @覆盖
    公共无效onDisabled（上下文的背景下）{
        context.stopService（新意图（背景下，WidgetService.class））;
    }
 

解决方案

重启后你OnEnabled被称为替代的onupdate所以从的onupdate移动code到一个单独的方法，然后调用该方法，从更新所有部件onEnabled

I have this simple widget and when I click on it, it should open my activity, it works, but it doesn't work after reboot. I must delete and then again add widget to my homescreen, because when I click on widget widget doesn't respond and doesn't open my activity. So where is the problem?

Code:

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        final int N = appWidgetIds.length;

        for(int i=0; i<N; i++){
            int appWidgetId = appWidgetIds[i];

            context.startService(new Intent(context, WidgetService.class));

            Intent intent = new Intent(context, WidgetDialog.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
            views.setOnClickPendingIntent(R.id.layout_widget, pendingIntent);

            appWidgetManager.updateAppWidget(appWidgetId, views);
        }
    }

    @Override
    public void onEnabled(Context context){
        context.startService(new Intent(context, WidgetService.class));
    }

    @Override
    public void onDisabled(Context context){
        context.stopService(new Intent(context, WidgetService.class));
    }

解决方案

After reboot you OnEnabled is called instead of onUpdate so move the code from onUpdate into a separate method and then call that method to update all widgets from onEnabled
