自定义通知中按钮的事件 OnClick

我有一个带有按钮的自定义通知。要设置通知并使用按钮上的 OnClick 事件，我使用了以下代码：

//Notification and intent of the notification 
Notification notification = new Notification(R.drawable.stat_notify_missed_call,
            "Custom Notification", System.currentTimeMillis());

Intent mainIntent = new Intent(getBaseContext(), NotificationActivity.class);
PendingIntent pendingMainIntent = PendingIntent.getActivity(getBaseContext(),
    0, mainIntent , 0);
notification.contentIntent = pendingMainIntent;

//Remoteview and intent for my button
RemoteViews notificationView = new RemoteViews(getBaseContext().getPackageName(),
    R.layout.remote_view_layout);

Intent activityIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:190"));
PendingIntent pendingLaunchIntent = PendingIntent.getActivity(getBaseContext(), 0,
            activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);

notificationView.setOnClickPendingIntent(R.id.button1,
    pendingLaunchIntent);

notification.contentView = notificationView;

notificationManager.notify(CUSTOM_NOTIFICATION_ID, notification);

使用此代码，我有一个带有自定义布局的自定义通知...但我无法单击该按钮！每次我尝试单击该按钮时，我都会单击整个通知，因此脚本会启动“mainIntent”而不是“activityIntent”。

我在互联网上读到此代码不适用于所有终端。我已经在模拟器和 HTC Magic 上尝试过，但总是遇到同样的问题：我无法单击按钮！

我的代码是对的吗？有人可以帮助我吗？

Thanks,

Simone

我正在我的中编写代码MyActivity.java扩展的类android.app.Activity

它创建一个自定义通知，当用户单击按钮时，它会发送一个broadcast。 有一个广播接收器接收broadcast.

private void createDownloadNotification() {
        Intent closeButton = new Intent("Download_Cancelled");
        closeButton.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

        PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, closeButton, 0);

        RemoteViews notificationView = new RemoteViews(getPackageName(), R.layout.widget_update_notification);

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.ic_launcher).setTicker("Ticker Text").setContent(notificationView);
        notificationView.setProgressBar(R.id.pb_progress, 100, 12, false);
        notificationView.setOnClickPendingIntent(R.id.btn_close, pendingSwitchIntent);

        notificationManager.notify(1, builder.build());

    }


public static class DownloadCancelReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {

            System.out.println("Received Cancelled Event");
        }
    }

注册接收者AndroidManifest.xml

<receiver android:name=".MainActivity$DownloadCancelReceiver" android:exported="false">
            <intent-filter>
                <action android:name="Download_Cancelled" />
            </intent-filter>
        </receiver>

由于它是内部类所以必须使用$ sign

小部件 xml 在这里
