Courses Plus Student 11,243 PointsAndroid new intent
When a user presses a button (there are multiple buttons) I want the program to open a new intent or activity with the string parsed on the current activity to the new activity also I want to handle the data that is being parsed once a button is pressed with a switch statement for example:
case button1: send foo to new activity case button2: send bar to new activity
etc

Treehouse TeacherWe haven't talked about this too much in our projects here, but Activities pass information between each other by attaching "extras" to the Intents. You can attach simple or more complex data. For a String, check out this Intent putExtra() method:
http://developer.android.com/reference/android/content/Intent.html#putExtra(java.lang.String, java.lang.String)
Quick example:
Intent intent = new Intent(this, TargetActivity.class);
intent.putExtra("sharedString", "This is the String to share");
startActivity(intent);

String myAmazingInformation = getIntent().getStringExtra("sharedString");Ben Jakuben

Treehouse TeacherExcellent - thanks for rounding out the example! As a side note, for more complex information you can attach a Bundle object to an Intent.
