ActivitiesManager工具类

参考:AppManager类,管理Activity和App

应用程序Activity管理类:用于Activity管理和应用程序退出

在BaseActivity 中引用:

package com.example.lenovo.myptrrefreshtest;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

public class BaseActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // 添加Activity到堆栈
        ActivitiesManager.getAppManager().addActivity(this);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        // 结束Activity&从堆栈中移除
        ActivitiesManager.getAppManager().finishActivity(this);
    }

}

Activity管理类:

package com.example.lenovo.myptrrefreshtest;

import android.app.Activity;
import android.app.ActivityManager;
import android.content.Context;

import java.util.Stack;

/** * 应用程序Activity管理类:用于Activity管理和应用程序退出 */

public class ActivitiesManager {

    private static Stack<Activity> activityStack;
    private static ActivitiesManager instance;

    private ActivitiesManager() {
    }

    /** * 单一实例 */
    public static ActivitiesManager getAppManager() {
        if (instance == null) {
            instance = new ActivitiesManager();
        }
        return instance;
    }

    /** * 添加Activity到堆栈 */
    public void addActivity(Activity activity) {
        if (activityStack == null) {
            activityStack = new Stack<Activity>();
        }
        activityStack.add(activity);
    }

    /** * 获取当前Activity(堆栈中最后一个压入的) */
    public Activity currentActivity() {
        Activity activity = activityStack.lastElement();
        return activity;
    }

    /** * 结束当前Activity(堆栈中最后一个压入的) */
    public void finishActivity() {
        Activity activity = activityStack.lastElement();
        finishActivity(activity);
    }

    /** * 结束指定的Activity */
    public void finishActivity(Activity activity) {
        if (activity != null) {
            activityStack.remove(activity);
            activity.finish();
            activity = null;
        }
    }

    /** * 结束指定类名的Activity */
    public void finishActivity(Class<?> cls) {
        for (Activity activity : activityStack) {
            if (activity.getClass().equals(cls)) {
                finishActivity(activity);
            }
        }
    }

    /** * 结束所有Activity */
    public void finishAllActivity() {
        for (int i = 0, size = activityStack.size(); i < size; i++) {
            if (null != activityStack.get(i)) {
                activityStack.get(i).finish();

            }
        }
        activityStack.clear();
    }


    /** * 结束所有Activity除了Login */
    public void killAllActivityNoLogin() {
        for (int i = 0, size = activityStack.size(); i < size; i++) {
            if (null != activityStack.get(i)) {
                if (activityStack.get(i).getClass() != LoginActivity.class) {
                    activityStack.get(i).finish();
                }
            }
        }
        activityStack.clear();
    }

    /** * 退出应用程序 */
    public void AppExit(Context context) {
        finishAllActivity();

        ActivityManager activityMgr = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        activityMgr.restartPackage(context.getPackageName());

        System.exit(0);
    }

}
