创建一个自己项目的Activity管理类（方法一 二均可用）记得点赞哦！谢谢方法一
public class ActivityManager {   private static Stack<Activity> activityStack;   private static ActivityManager instance;   private ActivityManager() {   }   public static ActivityManager getScreenManager() {      if (instance == null) {         instance = new ActivityManager();      }      return instance;   }      /**    * 获取当前Activity个数    */
   public int getActivitySize() {      if (activityStack != null && !activityStack.empty()) {         return activityStack.size();      }      return 0;   }   /**    * 退出栈顶Activity    */   public void popActivity(Activity activity) {      if (activity != null) {         activity.finish();         activityStack.remove(activity);         activity = null;      }   }   /**    * 获得当前栈顶Activity  先进后出原则    */   public Activity currentActivity() {      Activity activity = null;      if (activityStack != null && !activityStack.empty())         activity = activityStack.lastElement();      return activity;   }   /**    * 将当前Activity压入栈中    */   public void pushActivity(Activity activity) {      if (activityStack == null) {         activityStack = new Stack<Activity>();      }      activityStack.add(activity);   }   /**    * 退出栈中class上面的所有Activity。    */   public void popAllActivityExceptOne(Class cls) {      while (true) {         Activity activity = currentActivity();         if (activity == null) {            break;         }         if (activity.getClass().equals(cls)) {            break;         }         popActivity(activity);      }   }   /**    * 退出栈中除了包名外的所有Activity，    */   public void popAllActivityExceptPackageName(String packageName) {      for (Activity activity : activityStack) {         if (activity != null) {            String name = activity.getComponentName().getPackageName();            if (!name.contains(packageName)) {               popActivity(activity);            }         }      }   }   /**    * 退出栈中所有Activity    */   public void popAllActivity() {      while (true) {         Activity activity = currentActivity();         if (activity == null) {            break;         }         popActivity(activity);      }   }}

方法二
或者用简单的方法实现（清晰易懂操作）
public class ActivitysManager {    private static List<Activity> activityList;    private static ActivitysManager instance;    private ActivitysManager() {    }    public static ActivitysManager getActivitysManagerInstance() {        if (instance == null) {            instance = new ActivitysManager();        }        return instance;    }    //退出栈顶Activity    public void popActivity(Activity activity) {        if (activity != null) {            activityList.remove(activity);            activity = null;        }    }    //将当前Activity压入栈中    public void pushActivity(Activity activity) {        if (activityList == null) {            activityList = new LinkedList<Activity>();        }        activityList.add(activity);    }    //退出栈中所有Activity    public void exitApp(){        for(Activity activity:activityList){            if(!activity.isFinishing()){                activity.finish();            }        }        int id=android.os.Process.myPid();        if(id!=0){            android.os.Process.killProcess(id);        }    }}
