Question

我创建了锁屏应用程序，它可以正常启动应用程序。但我面临着通知问题。假设我将WhatsApp添加到app锁中，当我收到任何WhatsApp消息时，会出现锁定屏幕。我该如何解决呢？我使用下面的代码监控前台活动。是否有其他东西需要监控才能出现锁定屏幕。

private String aphpchecke() {

        String currentApp = "NULL";
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
            UsageStatsManager usm = null;
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP_MR1) {
                usm = (UsageStatsManager) this.getSystemService(USAGE_STATS_SERVICE);
                long time = System.currentTimeMillis();
                List<UsageStats> appList = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000 * 1000, time);
                if (appList != null && appList.size() > 0) {
                    SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
                    for (UsageStats usageStats : appList) {
                        mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
                    }
                    if (mySortedMap != null && !mySortedMap.isEmpty()) {
                        currentApp = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
                    }
                }
            } else {
                ActivityManager am = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE);
                assert am != null;
                List<ActivityManager.RunningAppProcessInfo> tasks = am.getRunningAppProcesses();
                currentApp = tasks.get(0).processName;
            }

            Log.e("adapter", "Current App in foreground is: " + currentApp);
            return currentApp;
        } else {


            ActivityManager mActivityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
            assert mActivityManager != null;
            List<ActivityManager.RunningTaskInfo> RunningTask = mActivityManager.getRunningTasks(1);
            ActivityManager.RunningTaskInfo ar = RunningTask.get(0);
            currentApp = ar.topActivity.getClassName();
            Log.i(TAG, "Top Activity " + currentApp);
            return currentApp;
        }


    }

一旦WhatsApp通知出现，前台活动就会显示WhatsApp软件包名称，因此逻辑上它必须显示锁定屏幕。

E/adapter: Current App in foreground is: com.google.android.apps.nexuslauncher
E/adapter: Current App in foreground is: com.whatsapp
D/FA: Logging event (FE): screen_view(_vs), Bundle[{firebase_event_origin(_o)=auto, firebase_previous_class(_pc)=LockScreen, firebase_previous_id(_pi)=7245334281643449211, firebase_screen_class(_sc)=LockScreen, firebase_screen_id(_si)=7245334281643449214}]

请指导，

此代码在通知时不返回前景。

{  "query_string":{
    "default_field":"text",
    "query":"\"instruments de musique\"",
    "enable_position_increments":false
  }
}

在通知上处理锁定屏幕
