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

You just have to send extras while calling your intent

like this:

Intent intent = new Intent(getApplicationContext(), SecondActivity.class); intent.putExtra("Variable Name","Value you want to pass"); startActivity(intent);

Now on the OnCreate method of your SecondActivity you can fetch the extras like this

If the value u sent was in "long"

long value = getIntent().getLongExtra("Variable Name which you sent as an extra", defaultValue(you can give it anything));

If the value u sent was a "String"

String value = getIntent().getStringExtra("Variable Name which you sent as an extra");

If the value u sent was a "Boolean"

Boolean value = getIntent().getStringExtra("Variable Name which you sent as an extra",defaultValue);
