Android：如何每1秒从另一个活动中获取数据？

Question

I have a timertask like this one:

<code>           
    new Timer().scheduleAtFixedRate(new TimerTask() {
        @Override
        public void run() {
            updateGraph(.....);
        }
    },0,2000);
</code>

But here within the updateGraph method i want to pass the Y-value. This Y-value is read thru another TimerTask in another activity, is this possible? Read every second from the other activity ?

Answer 1

Instead of Passing it through Method EveryTime

Declare a public static variable and update it at Regular Frequency in Your FirstActivty in TimerTask Method

 public static double Y;
    new Timer().scheduleAtFixedRate(new TimerTask() {
            @Override
            public void run() {
                 //update Y here
                updateGraph(.....);
            }
        },0,2000);

In Second Activity's Timer Task use

FirstActivity.Y

Answer 2

持续更新Timer（）中活动A和活动B中SharedPreference中的Y值。从SharedPreference中读取相同的Y值。

This issue solved! Thanks all, used: public static values between the activites!
