直接上程式碼：

Activity管理類：AppManager

/**

 * @author BiHaidong

 */
public class AppManager {
    private static Stack<Activity> activityStack = new Stack<Activity>();
 
    /**
     * 新增Activity到堆疊
     */
    public static void addActivity(Activity activity) {
        activityStack.push(activity);
    }
 
    /**
     * 獲取當前Activity（堆疊中最後一個壓入的）
     */
    public static Activity currentActivity() {
        return activityStack.lastElement();
    }
 
    /**
     * 結束當前Activity（堆疊中最後一個壓入的）
     */
    public static void finishCurrentActivity() {
        Activity activity = activityStack.pop();
        activity.finish();
    }
 
    /**
     * 結束指定的Activity
     */
    public static void finishActivity(Activity activity) {
        if (activity != null) {
            activityStack.remove(activity);
            if(!activity.isFinishing()) {
                activity.finish();
            }
        }
    }
 
    /**
     * 結束指定類名的Activity
     */
    public static void finishActivity(Class<?> cls) {
        for (Activity activity : activityStack) {
            if (activity.getClass().equals(cls)) {
                finishActivity(activity);
            }
        }
    }
 
    /**
     * 結束所有Activity
     */
    public static void finishAllActivity() {
        for (Activity activity : activityStack) {
            if (activity != null) {
                activity.finish();
            }
        }
        activityStack.clear();
    }
 
    /**
     * 退出應用程式
     */
    public static void AppExit(Context context) {
        try {
            finishAllActivity();
            ActivityManager manager = (ActivityManager) context
                    .getSystemService(Context.ACTIVITY_SERVICE);
            manager.killBackgroundProcesses(context.getPackageName());
            System.exit(0);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
 

然後是BaseActivity

public class BaseActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.setContentView(R.layout.base_layout);
 
        AppManager.addActivity(this);
}
