应用程序小部件在应用程序关闭后无法点击

Question

我有一个小部件，当应用程序在后台运行时它能很好地工作。但是当我使用应用程序管理器杀死应用程序时，小部件无法触发点击事件。然后我重新打开应用程序，小部件仍然无法触发点击事件。有任何想法吗？

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.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);

                    views.setTextViewText(R.id.positionNameTV, widgets.get(0).ilan_baslik);
                    views.setTextViewText(R.id.positionNameTV2, widgets.get(1).ilan_baslik);
                    views.setTextViewText(R.id.positionNameTV3, widgets.get(2).ilan_baslik);

                    views.setTextViewText(R.id.positionNameTV5, widgets.get(4).ilan_baslik);

                    Picasso.with(context)
                            .load("http:" + widgets.get(0).firma.logo)
                            .into(views, R.id.widgetIV, new int[]{appWidgetId});

                            .into(views, R.id.widgetIV5, new int[]{appWidgetId});

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

            }
        });
    }

    private PendingIntent getPendingSelfIntent(Context context, String action, int appWidgetId) {
        Intent intent = new Intent(context, getClass());
        intent.setAction(action);

我仍然没有解决方案，有什么想法吗？ :) - aligur

Answer 1

我目前也在寻找解决方案，希望这能有所帮助：

如果你检查SoundCloud的小部件，你会发现当应用程序被杀死时，

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. 你再次点击以播放音乐。

所以，我想，你应该运行一个服务，当用户点击小部件时，它将首先启动你的应用程序。
