At first I misunderstood your question, so now here’s some correction:

To launch an activity, use Shashank Kadne’s code in the code from TofeeqAhmad.

To pass data to subActivity2 you can add additional data to the intent that opens the Activity, in your case, an array of CharSequence items:

CharSequence[] sequences = ...;
intent.putExtra("resultsFromActivity1", sequences);

Then, in your activity’s onCreate handler you could check whether the intent contains an extra named “operation” an what its value is:

CharSequence[] items = itent.getCharSequenceExtra("resultsFromActivity1");
if (items != null)
{
    // Display the items
}
