用一个集合类对所有的Activity进行管理，实现随时控制Activity。用add(Activity activity)方法向List中添加Activity，用remove(Activity activity)方法从List中移除Activity，用finishProgram()方法将List中所有Activity移除并退出程序

import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.util.Log;public class ActivityStackControlUtil {	private static List
    
      activityList = new ArrayList
     
      ();	public static void remove(Activity activity) {		activityList.remove(activity);	}	public static void add(Activity activity) {		activityList.add(activity);	}	public static void finishProgram() {		Log.i("oyp", "finishProgram");		for (Activity activity : activityList) {			if (!activity.isFinishing()) {				activity.finish();			}		}		android.os.Process.killProcess(android.os.Process.myPid());	}}
