android - 当应用程序被杀死时，应用程序小部件点击不起作用

Question

我有一个小部件，当应用程序在后台运行时它运行良好。但是当我用应用程序管理器终止应用程序时，小部件不会触发点击事件。然后我重新打开应用程序，小部件仍然没有触发点击事件。有什么想法吗？

public class Widget extends AppWidgetProvider {

    private ArrayList<Widget> widgets;
    private static String listing1 = "";
    private static String listing2 = "";
    private static String listing3 = "";
    private static String listing4 = "";
    private static String listing5 = "";
    RemoteViews views;

    public void onUpdate(final Context context, final AppWidgetManager appWidgetManager, final int[] appWidgetIds) {
        Log.i("ExampleWidget", "Updating widgets " + Arrays.asList(appWidgetIds));

        // Perform this loop procedure for each App Widget that belongs to this

        HashMap<String, String> params = new HashMap<>();
        params.put("islem", "recommendation");

        ServiceConnector.secretcvAPI.getWidgetItems(params, new SuccessCallback<GetWidgetResponse>() {
            @Override
            public void success(GetWidgetResponse getWidgetResponse, Response response) {
                widgets = getWidgetResponse.widgets;

                for (int appWidgetId : appWidgetIds) {

                    listing1 = widgets.get(0).ilan_id;
                    listing2 = widgets.get(1).ilan_id;
                    listing3 =  widgets.get(2).ilan_id;
                    listing4 = widgets.get(3).ilan_id;
                    listing5 = widgets.get(4).ilan_id;
                    // Get the layout for the App Widget and attach an on-click listener
                    // to the button
                    views = new RemoteViews(context.getPackageName(), R.layout.widget);
                    views.setOnClickPendingIntent(R.id.listing1, getPendingSelfIntent(context, widgets.get(0).ilan_id, appWidgetId));
                    views.setOnClickPendingIntent(R.id.listing2, getPendingSelfIntent(context, widgets.get(1).ilan_id, appWidgetId));
                    views.setOnClickPendingIntent(R.id.listing3, getPendingSelfIntent(context, widgets.get(2).ilan_id, appWidgetId));
                    views.setOnClickPendingIntent(R.id.listing4, getPendingSelfIntent(context, widgets.get(3).ilan_id, appWidgetId));
                    views.setOnClickPendingIntent(R.id.listing5, getPendingSelfIntent(context, widgets.get(4).ilan_id, appWidgetId));

                    views.setTextViewText(R.id.listingNameTV, widgets.get(0).firma.isim);
                    views.setTextViewText(R.id.listingNameTV2, widgets.get(1).firma.isim);
                    views.setTextViewText(R.id.listingNameTV3, widgets.get(2).firma.isim);

                    // Tell the AppWidgetManager to perform an update on the current app
                    // widget
                    appWidgetManager.updateAppWidget(appWidgetId, views);

我目前也在寻找解决方案，希望这会有所帮助:

如果你查看 soundcloud 的小部件，你会注意到当应用程序被终止时，

1. 小部件没有布局来指示“关闭”状态
2. 你点击它，它首先启动应用程序，更新小部件的布局和按钮
3. 您再次点击以播放您的音乐。

所以，我在想，您应该运行一个服务，该服务会在用户单击小部件时首先启动您的应用。
