我添加了一个按钮，通知里面

I added a button inside a notification

但我不知道如何使用它调用一个函数时，它的点击。

but I don't know how to have it call a function when it's clicked.

我想这样的方法https://$c$c.google.com/p/languagepickerwidget/source/browse/trunk/trunk/src/org/gnvo/langpicker/LangPicker.java因为它也使用RemoteViews对象，但没有任何反应，当我点击该按钮。

I tried an approach like this https://code.google.com/p/languagepickerwidget/source/browse/trunk/trunk/src/org/gnvo/langpicker/LangPicker.java since it's also using a RemoteViews object but nothing happens when I click the button.

这是我目前有：

private void createNotification(){
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager notificationManager = (NotificationManager) getSystemService(ns);

    Notification notification = new Notification(R.drawable.ic_launcher, null, System.currentTimeMillis());
    RemoteViews notificationView = new RemoteViews(getPackageName(), R.layout.notification_switch);

    //the intent that is started when the notification is clicked (works)
    Intent notificationIntent = new Intent(this, SettingsActivity.class);
    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

    notification.contentView = notificationView;
    notification.contentIntent = pendingNotificationIntent;
    notification.flags |= Notification.FLAG_NO_CLEAR;

    //this is the intent that is supposed to be called when the button is clicked
    Intent switchIntent = new Intent(this, switchButtonListener.class);
    PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, switchIntent, 0);

    notificationView.setOnClickPendingIntent(R.id.buttonswitch, pendingSwitchIntent);

    notificationManager.notify(1, notification);
}

public static class switchButtonListener extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("TAG", "test");
    }

}

我就可以开始使用该按钮的活动，但我没有成功有它调用一个简单的函数。什么是做到这一点的最好方法是什么？

I can start an activity with the button but I didn't succeed to have it call a simple function. What would be the best way to do this?

编辑： 我发现我在AndroidManifest.xml中必须注册switchButtonListener

I found out that I had to register "switchButtonListener" in AndroidManifest.xml

<receiver android:name="SettingsActivity$switchButtonListener" />

来源： Android的活动，没有GUI

它的工作原理吧。

后来我才发现原来我也可以用code这样来达到同样的事情，而无需修改清单。

Later I found out that I can also use code like this to achieve the same thing without modifying the manifest.

switchButtonListener = new SwitchButtonListener();
registerReceiver(switchButtonListener, new IntentFilter(SWITCH_EVENT));

public class switchButtonListener extends BroadcastReceiver {
@Override
    public void onReceive(Context context, Intent intent) {
        Log.d("TAG", "test");
    }

}

Intent switchIntent = new Intent(LangService.SWITCH_EVENT);
PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(context, 0, switchIntent, 0);

notificationView.setOnClickPendingIntent(R.id.buttonswitch, pendingSwitchIntent);

需要注意的是这种方式，我可以不用静态属性声明switchButtonListener类（如果不是一成不变的，它会崩溃在previous例子）给了我更大的灵活性。 不要忘了以后调用unregisterReceiver（）。

Note that this way I can declare the switchButtonListener class without the static attribute (if not static, it would crash in the previous example) giving me much more flexibility. Don't forget to call unregisterReceiver() later.
