Android 打开错误活动的多个意图的挂起意图

我有两个小部件A和B。我有两个问题：

在多次点击一个小部件（a或B）时 同样的活动也开始了

有时小部件A打开小部件B活动，反之亦然

这是我的密码：

控件提供程序类：

 for (int appWidgetId : appWidgetIds) {
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.favorite_flavor_widget);
        Intent intent = new Intent(context, SplashActivity.class);
        intent.setAction("FromFavoriteFlavorWidget");
        intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
        intent.putExtra("FromFavoriteFlavorWidget", true);
        PendingIntent pendingIntent = PendingIntent.getActivity(context,
                0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.favoriteFlavorBox, pendingIntent);
        appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
        appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
    }

 for (int appWidgetId : appWidgetIds) {
            RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                    R.layout.report_food_widget);
            Intent intent = new Intent(context, SplashActivity.class);
            intent.setAction("FromReportFoodWidget");
            intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
            intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
            intent.putExtra("FromReportFoodWidget", true);
            PendingIntent pendingIntent = PendingIntent.getActivity(context,
                    0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
            remoteViews.setOnClickPendingIntent(R.id.reportFoodBox, pendingIntent);
            appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
        }

小部件B提供程序类：

 for (int appWidgetId : appWidgetIds) {
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.favorite_flavor_widget);
        Intent intent = new Intent(context, SplashActivity.class);
        intent.setAction("FromFavoriteFlavorWidget");
        intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
        intent.putExtra("FromFavoriteFlavorWidget", true);
        PendingIntent pendingIntent = PendingIntent.getActivity(context,
                0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.favoriteFlavorBox, pendingIntent);
        appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
        appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
    }

 for (int appWidgetId : appWidgetIds) {
            RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                    R.layout.report_food_widget);
            Intent intent = new Intent(context, SplashActivity.class);
            intent.setAction("FromReportFoodWidget");
            intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
            intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
            intent.putExtra("FromReportFoodWidget", true);
            PendingIntent pendingIntent = PendingIntent.getActivity(context,
                    0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
            remoteViews.setOnClickPendingIntent(R.id.reportFoodBox, pendingIntent);
            appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
        }

设置标志为

Intent.FLAG\u ACTIVITY\u CLEAR\u TOP Intent.FLAG\u ACTIVITY\u REORDER\u TO\u FRONT

并尝试将其添加到清单中

android:launchMode="singleTask"

及

你为什么打电话来

appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
        appWidgetManager.updateAppWidget(appWidgetId, remoteViews);

2次只调用一次，并对多实例问题使用

android:launchMode=“singleTop”

setFlags（Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK）；试试这个，不起作用。正在创建多个活动实例。实际上，当应用程序完全关闭时，它会工作，但如果应用程序位于后台，则不会。请在按下“活动”的后退按钮时告诉我。导航问题？现在，你应该使用TaskStackBuilder和PendingEvent。现在请检查问题是，如果应用程序在后台，我点击小部件，它不会打开正确的片段，它只会打开应用程序并显示现有片段。我找到了解决方案。只需要把这些支票放在电话里。
