如何通过点击按钮使小部件工作？

Question

当我将Midget拖放到桌面上时，我的Midget工作正常。但是，我也希望在按下按钮时从我的TestActivity界面执行我的小部件操作。

这是我的小工具 -

    package com.droideilhan.ultrasimpletaskkiller;
    public class USTaskKillerWidget extends AppWidgetProvider {
    public static String ACTION_WIDGET_RECEIVER = "ActionReceiverUltraSimpleTaskKillerWidget";

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);

        Intent clicSurBtnKillIntent = new Intent(context, USTaskKillerWidget.class);
        clicSurBtnKillIntent.setAction(ACTION_WIDGET_RECEIVER);
        PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, clicSurBtnKillIntent, 0);
        remoteViews.setOnClickPendingIntent(R.id.btnKill, actionPendingIntent);

        appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // v1.5 fix that doesn't call onDelete Action
        final String action = intent.getAction();
        if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
            final int appWidgetId = intent.getExtras().getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
            if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
                this.onDeleted(context, new int[] { appWidgetId });
            }
        } else {
            // On a cliqué sur le bouton
            if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) {

                // Liste des packages à ne pas tuer.
                List<String> reservedPackages = new ArrayList<String>();
                reservedPackages.add("system");
                reservedPackages.add("com.android.launcher2");
                reservedPackages.add("com.android.inputmethod.latin");
                reservedPackages.add("com.android.phone");
                reservedPackages.add("com.android.wallpaper");
                reservedPackages.add("com.google.process.gapps");
                reservedPackages.add("android.process.acore");
                reservedPackages.add("android.process.media");

                // On tue tous les processus, sauf ceux de la liste
                int compteProcessusTues = 0;
                ActivityManager am = (ActivityManager) context.getSystemService(Activity.ACTIVITY_SERVICE);
                List<RunningAppProcessInfo> listeProcessus = am.getRunningAppProcesses();
                for(RunningAppProcessInfo processus : listeProcessus) {           
                    //Log.d("TKTKTK", "========="+processus.pid+" : "+processus.processName);
                    String packageName = processus.processName.split(":")[0];
                    if (!context.getPackageName().equals(packageName) && !reservedPackages.contains(packageName)) {
                        am.restartPackage(packageName);
                        compteProcessusTues++;
                    }
                }
                // Auto-kill (désactivé dans le cas d'un widget)
                //am.restartPackage(context.getPackageName());


            }
            super.onReceive(context, intent);
        }
    }
}

问题 - 小部件的操作永远不会被调用，没有强制关闭，也没有错误。

以下是 TestActivity 中的按钮（这是我到目前为止所尝试过的）

public void test(View view) {
    Intent intent = new Intent();
    intent.setAction("android.appwidget.action.APPWIDGET_UPDATE");
    sendBroadcast(intent);
    intent.setAction("com.droideilhan.android.widget.buttons.ButtonWidget.ACTION_WIDGET_RECEIVER");
    sendBroadcast(intent);
}
