Question

我现在尝试为年龄进行调试，我似乎无法找到问题：

我有一个广播接收器，它成功接收广播。通知有两个操作（＆＃34;按钮＆＃34;）：

firstIntent = null; 
secondIntent = null;

firstPendingIntent = null; //first "button" to join with the first intent
secondPendingIntent = null; //second "button" to join with the second intent

if(boolean){

//relevant

firstIntent = new Intent(getBaseContext(), NotificationFunctions.class).putExtra("action", "do_this");
secondIntent = new Intent(getBaseContext(), NotificationFunctions.class).putExtra("action", "do_that");

}else{

firstIntent = new Intent(getBaseContext(), NotificationFunctions.class).putExtra("action", "do_another_this");
secondIntent = new Intent(getBaseContext(), NotificationFunctions.class).putExtra("action", "do_another_that");

}

firstPendingIntent = PendingIntent.getBroadcast(getBaseContext(), 0, firstIntent, PendingIntent.FLAG_UPDATE_CURRENT);

secondPendingIntent = PendingIntent.getBroadcast(getBaseContext(), 0, secondIntent, PendingIntent.FLAG_UPDATE_CURRENT);

notification = new NotificationCompat.Builder(getApplicationContext())
                                    .setContentTitle(notification_title)
                                    .setContentText(notification_text)
                                    .setTicker("Notification!")
                                    .setWhen(System.currentTimeMillis())
                                    .setDefaults(Notification.DEFAULT_SOUND)
.addAction(R.drawable.abc_cab_background_top_holo_light, first_option, firstPendingIntent)
.addAction(R.drawable.abc_cab_background_top_holo_dark, second_option, secondPendingIntent)
                                    .setAutoCancel(true)
                                    .setSmallIcon(R.drawable.ic_stat_name)
                                    .build();

每当我在 broadcastReceiver 中进行调试时，出于某种原因，来自 extras 的操作始终会记录＆＃34; do_that＆＃34;，即使我点击了第一个或第二个通知按钮。有什么理由吗？我似乎无法理解为什么。

public class NotificationFunctions extends BroadcastReceiver {

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

        boolean feedback;

        String action = intent.getExtras().getString("action");

        Log.wtf("...", action); //logs do_that

    }}

这有什么原因吗？

因为firstPendingIntent == secondPendingIntent。

如果已经PendingIntent符合您的请求，则getBroadcast()会返回现有的PendingIntent。 FLAG_UPDATE_CURRENT表示要替换Intent内包含的PendingIntent中的额外内容。

在您的两个getBroadcast()来电之一中，将0替换为其他一些号码，以获取不同的PendingIntent个对象。

此外，我建议您将getBaseContext()和getApplicationContext()替换为this。只有当您知道正是为什么使用它们时才能使用getBaseContext()和getApplicationContext()。

通知PendingIntent硬错误（或非常简单）
