Android service 判断前台activity

问题描述：

如何在service中判断当前前台运行的是哪个Activity(如果当前应用在前台的话)?

答

一般的话，都会自己建立一个activity的管理栈，所有activity都继承BaseActivity, Base中管理入栈出栈，当前前台运行的activity 就是栈顶的那个咯

答

        ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        String activity = am.getRunningTasks(1).get(0).topActivity.getClassName();

答

楼上已经说出了思路了，我这里直接给你帖段代码

 public class ActivityController 
{
    public static List<Activity> mActivityList = new ArrayList<Activity>();  
    private static Activity mCurrentActivity;  

    public static void addActivity(Activity activity) {  
        mActivityList.add(activity);  
    }  
public static void removeActivity(Activity activity) {  
        mActivityList.remove(activity);  
    }  

    public static void setCurrentActivity(Activity activity) {  
        mCurrentActivity = activity;  
    }  

    public static Activity getCurrentActivity() {  
        return mCurrentActivity;  
    }  
    public static void finishAll() {  
        for (Activity activity : mActivityList) {  
            if (!activity.isFinishing()) {  
                activity.finish();  
            }  
        }  
    }  

}

基类在做相应处理就行，然后要获取当前前台Actitivy直接获取mCurrentActivity就行
