推荐答案

据我知道你不能访问UI组件of2nd活动，而在第一项活动之中。所以最好的办法是通过意图的putExtra方法的值，然后将其通过获取其在第二届活动的OnCreate到TextView的。下面这里是链接，显示了该方法

As far as i know you cannot access the UI component of2nd activity while being in first activity. so the best way is to pass the value through putExtra method of intents and then set it to textview in the oncreate of 2nd activity by getting it. here below is link which shows this method
