如何将对象从一项活动传递给另一项活动Android

我有两个活动Activity 1和Activity 2.对于这两个活动，我有两个XML布局1.xml和2.xml.在1.xml中，我有Button；在2.xml中，我有TextView.因此，我想单击第一个活动上的Button，我想打开第二个活动，并且还想在Activity2中出现的Textview上显示Button中显示的文本.我的意思是说，假设Button中的文本为"ADD"，那么此文本将显示在TextView中.

I have two activities Activity 1 and Activity 2. For these two activities, I have two XML layout 1.xml and 2.xml. In 1.xml I have a Button and in 2.xml I have TextView. So what I want is on click of Button which is on the first activity I want to open the 2nd activity and also want to display the text shown in Button on the Textview present in Activity2. I mean to say that suppose the text in the Button is "ADD" then this text will be displayed in TextView.

注意:Button在Activity1上，而TextView在Activity2上

Note: Button is on Activity1 and TextView is on Activity2

推荐答案

INTENT 使用Intent传递数据，putExtra()将允许您放置数据

INTENT Use Intent to pass data, putExtra() will allow you to put data

Intent myIntent = new Intent(ActivityA.this, Activityb.class);
myIntent.putExtra("key", "value");
startActivity(myIntent); 

活动B

Intent myIntent = getIntent(); // this is just for example purpose
myIntent.getExtra("key");
