Question

I am using intent to call activity here and I need to send to long variable to the other activity.

Porjct.java

  Intent i = new Intent(ProjectList.this,RoleList.class);
  Bundle c = new Bundle();            
  c.putLong("PID", projectID );
  c.putLong("CTSID", castingTimeSlotID);
  i.putExtras(c);
  startActivityForResult(i,0);
  finish();

RoleList.java

public void onActivityResult(int requestCode, int resultCode, Intent data) {    
            Bundle c = new Bundle();
        c = data.getExtras();
    projectID = b.getLong("PID");
    castingTimeSlotID = b.getLong("CTSID");}

This is not working.

Answer 1

Edit:

The onActivityResult() should be in ProjectList.java – it will be called when your child Activity returns.

Your child Activity in RoleList.java should retrieve the data sent by the parent from the Bundle passed via onCreate()

If this is a little confusing; I suggest you read this first: http://www.remwebdevelopment.com/dev/a33/Passing-Bundles-Around-Activities.html – the example in there is very complete and they explain it better than I do. Notice how they pass data with key “mykey” from the parent Activity to the child; this is what you want to do.

Previous useless answer of mine follows

I think you don’t need to retrieve the extras via a Bundle. Try this:

public void onActivityResult(int requestCode, int resultCode, Intent data) {    
    projectID = data.getLongExtra("PID");
    castingTimeSlotID = data.getLongExtra("CTSID");
}
