获取列表，然后检查是否有锁屏的应用程序包名称。

下面是代码：

ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE); 
List<ActivityManager.RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE); 

long currentMillis = Calendar.getInstance().getTimeInMillis(); 
Calendar cal = Calendar.getInstance(); 

for (ActivityManager.RunningServiceInfo info : services) { 
    cal.setTimeInMillis(currentMillis-info.activeSince); 
    Log.i("TAG", String.format("Process %s has been running since: %d ms",info.process, info.activeSince)); 
}

的logcat：

TAG: Process com.android.systemui has been running since: 86526 ms

这是锁屏^

TAG: Process com.qualcomm.telephony has been running since: 68521 ms 
TAG: Process com.motorola.ccc has been running since: 57456 ms 
TAG: Process com.google.android.music:main has been running since: 26245 ms

这就是我不知道软件包名称的问题 –

答

您可以任意确定包名通过分析Android日志来获得前景的。例如，如果您打开Google地图，则单击设备的“主页”按钮将在日志中显示此内容（我通常按照ActivityManager字符串进行过滤）。

START u0 {act=android.intent.action.MAIN cat=[android.intent.category.HOME] 
flg=0x10200000 cmp=com.android.launcher/com.android.launcher2.Launcher}

这表明你的主屏幕Activity的包名是com.android.launcher

然而，当我点击我的Nexus 4家按钮，显示从任何应用程序的锁屏，它从来没有显示正在推出的另一款活动。这让我觉得这不是我们所理解的典型Activity。

如果您查看Android源代码KeyguardViewMediator.java的源代码，您会发现一个名为private void doKeyguardLocked(Bundle options)的方法。我从经验中知道，将源改为立即从此方法返回将禁用锁屏。 KeyguardViewMediator.java的来源显示它在包com.android.keyguard中，我相信这是您正在寻找的包。

至于动态获取包名，它对我来说似乎不可能。但是，如果您已经提前知道包名，则不需要动态获取它。

我希望这会有所帮助。
