How to pass object from one activity to another in Android

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.

Note: Button is on Activity1 and TextView is on Activity2

Answer 1

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

ActivityA

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

ActivityB

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