Android AppWidget的按钮点击事件在家庭启动器强制停止后未收到

2022-09-04 23:39:12

我有一个应用程序小部件,可以在我的提供商中接收点击事件。
但是,当我尝试强制关闭主启动器时,单击事件丢失。
我甚至把断点放在所有, ...等:连接似乎丢失了。onUpdate()onEnabled()onReceived()

因此,如何“重新连接”按钮事件?

WidgetProvider 扩展 :AppWidgetProvider

@Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        Log.d(TAG, "onUpdate()");
        Log.d(TAG, "isLoading: " + CONSTANT.isLoading);
        // update each of the widgets with the remote adapter from updateService
        // Get all ids
        ComponentName thisWidget = new ComponentName(context, ScoreWidgetProvider.class);
        int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);

        // Build the intent to call the service
        Intent intent = new Intent(context.getApplicationContext(), UpdateWidgetService.class);
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, allWidgetIds);

        // Update the widgets via the service
        context.startService(intent);

//      super.onUpdate(context, appWidgetManager, appWidgetIds);
    }  

UpdateWidgetService extends :Service

@Override
        public void onStart(Intent intent, int startId) {

            Log.i(TAG, "Called");

            AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(getApplicationContext());

            int[] appWidgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);

            for (int i = 0; i < appWidgetIds.length; ++i) {
                // Here we setup the intent which points to the StackViewService which will
                // provide the views for this collection.
                Intent remoteViewsIntent = new Intent(this.getApplicationContext(), ScoreWidgetRemoteViewsService.class);
                remoteViewsIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
                // When intents are compared, the extras are ignored, so we need to embed the extras
                // into the data so that the extras will not be ignored.
                remoteViewsIntent.setData(Uri.parse(remoteViewsIntent.toUri(Intent.URI_INTENT_SCHEME)));
                RemoteViews rv = new RemoteViews(this.getApplicationContext().getPackageName(), R.layout.widget_layout);
                rv.setRemoteAdapter(appWidgetIds[i], R.id.score_list, remoteViewsIntent);

                // Set the empty view to be displayed if the collection is empty.  It must be a sibling
                // view of the collection view.
                rv.setEmptyView(R.id.score_list, R.id.empty_view);

                // Bind the click intent for the refresh button on the widget
                final Intent refreshIntent = new Intent(this.getApplicationContext(), ScoreWidgetProvider.class);
                refreshIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                refreshIntent.setAction(ScoreWidgetProvider.REFRESH_ACTION);
                final PendingIntent refreshPendingIntent = PendingIntent
                        .getBroadcast(this.getApplicationContext(), 0, refreshIntent, PendingIntent.FLAG_UPDATE_CURRENT);
                rv.setOnClickPendingIntent(R.id.btn_refresh, refreshPendingIntent);

                appWidgetManager.updateAppWidget(appWidgetIds[i], rv);
            }

    //        stopSelf();

            super.onStart(intent, startId);
        }

确保在函数中使用正确的上下文。在代码部分签出,传入错误类型的上下文可能会导致错误。以下是详细信息的链接:上下文onStartgetApplicationContextonStart
