android - appwidgetprovider 可以实现 onactivityresult 怎么用呢？

Question

我需要在 appwidget 上使用 onactivityresult 但我该如何使用它？它不叫

公共类 MainActivity 扩展 AppWidgetProvider 实现 OnActivityResultListener { Context context;

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
        int[] appWidgetIds) {
    super.onUpdate(context, appWidgetManager, appWidgetIds);
    this.context = context;
    for (int i = 0; i < appWidgetIds.length; i++) {
        int appWidgetId = appWidgetIds[i];
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
        PendingIntent pending = PendingIntent.getActivity(context, 0, intent, PendingIntent.PARCELABLE_WRITE_RETURN_VALUE);
        RemoteViews views = new RemoteViews(context.getPackageName(),
                R.layout.activity_main);

        views.setOnClickPendingIntent(R.id.imageButton1, pending);
        appWidgetManager.updateAppWidget(appWidgetId, views);
    }

}
@Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);
}

@Override
public boolean onActivityResult(int requestCode, int resultCode, Intent data) {}

onActivityResult()仅适用于Activity及其子类。那是因为startActivityForResult()仅在Activity及其子类上可用。
