Here is some sample code from one of my apps:
Intent newIntent = new Intent(Intent.ACTION_MAIN);
newIntent.setClass(this, ActivityListView.class);
newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(newIntent);
A couple things to note:
- This is code taken from a class that inherits from Activity, which
inherits from Context. Context is the class that has the startActivity
method
- The setClass method sets the class of the Activity you want to launch
- The call to setFlags is optional but is worth looking into as it can
change the behavior of quite a bit
- You would want to grab contact data from your current activity and add
it to the intent via one of its overloaded putExtra methods
Thanks,
Justin
