Activity您可以通过分析 Android 日志来确定任何出现在前台的程序包名称。例如，如果您打开了 Google 地图，单击设备的主页按钮将在日志中显示此内容（我通常按ActivityManager字符串过滤）。

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

显示主屏幕的包名Activity是com.android.launcher

但是，当我单击 Nexus 4 主页按钮以显示任何应用程序的锁屏时，它永远不会显示正在启动的另一个 Activity。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). 我从经验中知道，将源更改为立即从此方法返回将禁用锁屏。的来源KeyguardViewMediator.java显示它在 packagecom.android.keyguard中，我相信这就是您正在寻找的包。

至于动态获取包名，对我来说似乎是不可能的。但是，如果您已经提前知道包名称，则无需动态获取它。

我希望这有帮助。

获取所有进程的列表，然后检查屏幕锁定应用程序包名称。

以下是代码： 

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));
}

日志猫：

那是锁屏^
