Question

我希望在收到通知超过1时通过解析堆叠多个收到的通知，并在一个通知中显示给用户。我搜索了这么多，但我找不到合适的解决方案。那可能吗？

你需要的是一个自己的PushReceiver，所以根据Parse文档，你在清单中声明了接收器

<receiver
    <!-- Put here path to a class that will handle pushes -->
    android:name="com.domain.ReceiverClass"
    android:exported="false">
    <intent-filter>
        <action android:name="com.parse.push.intent.RECEIVE"/>
        <action android:name="com.parse.push.intent.DELETE"/>
        <action android:name="com.parse.push.intent.OPEN"/>
    </intent-filter>
</receiver>

在这个PushReceiver类中，您实现了有关显示推送的所有必需逻辑

public class PushReceiver extends ParsePushBroadcastReceiver {
    @Override
    protected void onPushReceive(Context context, Intent intent) {
        //Don't call super.onPushReceive!
        JSONObject pushData = new JSONObject(intent.getStringExtra(KEY_PUSH_DATA));
        //Here is how you obtain data
        String alert = pushData.optString("alert", "Notification received.");
        //Any manipulations with stacking go here
    }
}

修改即可。所以一切都取决于您的要求。例如，您可以在接收器中累积通知，并安排AlarmManager在5分钟后唤醒。将当前通知数作为额外通过，然后检查新推送是否到达。如果是这样 - 等待下一个警报，如果没有 - 显示所有内容。

        SharedPreferences prefs = context.getSharedPreferences(KEY_NOTIFICATIONS,
                Context.MODE_PRIVATE
        );
        JSONArray stacked = new JSONArray(prefs.getString(KEY_STACKED, ""));
        stacked.put(alert);
        prefs.edit().putString(KEY_STACKED, stacked.toString()).apply();
        Intent i = new Intent(context, ActualProcessor.class);
        i.putExtra(EXTRA_COUNT, stacked.length());
        PendingIntent receiver = PendingIntent.getBroadcast(context, CODE, i, 0);
        AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP,
                System.currentTimeMillis() + TimeUnit.MINUTES.toMillis(5),
                receiver
        );
