推荐答案

我对我的问题的回答如下.

I got answer to my question as follows.

public static ArrayList<ActivityInfo> getAllRunningActivities(Context context) {
    try {
        PackageInfo pi = context.getPackageManager().getPackageInfo(
                context.getPackageName(), PackageManager.GET_ACTIVITIES);

        return new ArrayList<>(Arrays.asList(pi.activities));

    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
        return null;
    }
}
