Transfer data from one Activity to Another Activity Using Intents

Question

I would like to be able to transfer data from one activity to another activity. How can this be done?

Answer 1

Your Purpose

Suppose You want to Go From Activity A to Activity B.

So We Use an Intent to switch activity

the typical code Looks Like this -

In Activity A [A.class]

//// Create a New Intent object
Intent i = new Intent(getApplicationContext(), B.class);

/// add what you want to pass from activity A to Activity B
i.putExtra("key", "value");

/// start the intent
startActivity(i);

In Activity B [B.class]

And to Get the Data From the Child Activity

Intent i = getIntent();

if (i!=null) {
   String stringData= i.getStringExtra("key");
}
