我正在编写一个包含 2 个按钮的小部件。问题是 - 有时,当小部件被删除/添加到屏幕时,按钮不起作用,似乎它们没有附加任何监听器。我在 BroadcastReceiver 中使用以下代码:
@Override
public void onUpdate(final Context context, final AppWidgetManager aAppWidgetManager,
final int[] appWidgetIds) {
super.onUpdate(context, aAppWidgetManager, appWidgetIds);
Log.d("Widget_On_update", "Total widgets : " + appWidgetIds.length);
for (final int widgetId : appWidgetIds) {
Log.d("Widget_On_update", "Updating widget : " + widgetId);
final RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
updateActionListener(true, context, appWidgetIds, remoteViews, UPDATE_DATA_ACTION, id.button_data_update);
updateActionListener(true, context, appWidgetIds, remoteViews, UPDATE_WIFI_ACTION, id.button_wifi_update);
aAppWidgetManager.updateAppWidget(widgetId, remoteViews);
}
updateStatus(context);
}
private void updateActionListener(final boolean add, final Context context, final int[] appWidgetIds,
final RemoteViews aRemoteViews, final String aAction, final int aViewId) {
// Register an onClickListener
final Intent intent = new Intent(context, DataToggleWidgetProvider.class);
intent.setAction(aAction);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
final PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
if (add) {
aRemoteViews.setOnClickPendingIntent(aViewId, pendingIntent);
} else {
pendingIntent.cancel();
}
}
我为PendingIntent.getBroadcast的第二个参数尝试了不同的值,比如Math.random,一个静态计数器等等。这些方法都不起作用。谁能帮我 ?
先感谢您。
