Passing Data With an Intent

This is the code to pass data from one activity to another through an Intent.

This is the code used to create and pass data into an Intent.

String dataToPass = "The next activity needs this sentence.";
...
Intent intent = new Intent(this, NextActivity.class);
intent.putExtras("KeyToAccessData", dataToPass);
startActivity(intent);

And this is how you catch that data from the receiving activity:

String dataToCollect;
...
Intent intent = getIntent();
dataToCollect = intent.getStringExtra("KeyToAccessData");

Note that the getIntent() method is part of the Android Activity class. Every Activity knows it’s own intent. We are just creating a way to reference it easily. You can also collect Integers (getIntExtra()) and other various data types using this method.
