如何检查Android中当前正在运行的应用程序？

我想以编程方式在android中查看当前正在运行的应用程序，类似于如果按住HOMEbutton，它将显示6个应用程序。

我最感兴趣的应用程序名称。

Answer 1

你可以使用当前的名字包

ActivityManager am = (ActivityManager) mContext .getSystemService(Activity.ACTIVITY_SERVICE); String packageName = am.getRunningTasks(1).get(0).topActivity .getPackageName(); 

您可以使用此软件包名称来获取当前活动的应用程序

Answer 2

您可以检查列表中每个元素的processName，看它是否是您要查找的进程。 你可以使用这个代码

 boolean isNamedProcessRunning(String processName){ if (processName == null) return false; ActivityManager manager = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE); List<RunningAppProcessInfo> processes = manager.getRunningAppProcesses(); for (RunningAppProcessInfo process : processes) { if (processName.equals(process.processName)) { return true; } } return false; } 

Answer 3

长按HOME键会显示最近（不一定是正在运行的）任务的列表。

ActivityManager有你所需要的。 查看getRunningAppProcesses或getRunningTasks 。

您可以通过“adb shell”运行dumpsys activity来查看这些信息（以及更多）。
