如何以编程方式获取有关Android中所有正在运行的活动的信息? [英] How to get info about all running activities in android programmatically?

问题描述

在android中，您可以通过查看Logcat来获取有关正在运行的活动的信息.

In android, you get info about running activities by watching the Logcat.

例如，如果您打开相机，则会将其记录在Logcat中.

For example if you open camera, it is logged in the Logcat.

有没有办法以编程方式获取该信息?

Is there a way to get that info programmatically?

推荐答案

ActivityManager m = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE );
    List<RunningTaskInfo> runningTaskInfoList =  m.getRunningTasks(10);
    Iterator<RunningTaskInfo> itr = runningTaskInfoList.iterator();
    while(itr.hasNext())
    {
        RunningTaskInfo runningTaskInfo = (RunningTaskInfo)itr.next();
        int id = runningTaskInfo.id;
        CharSequence desc= runningTaskInfo.description;
        String topActivity = runningTaskInfo.topActivity.getShortClassName();
        int numOfActivities = runningTaskInfo.numActivities;
    }

注意:您必须在清单文件中指定 android.permission.GET_TASKS 权限.

Note: You have to specify android.permission.GET_TASKS permission in Manifest file.
