Question

I have a loop where i am created multiple button instances and with each instance they have a TouchListener. However, i am having trouble figuring out how to manage when the different buttons have been touched. What i am trying to accomplish is that each button represents a textview and when i touch the button i want to add that particular textview associated with that instance of the button to an arraylist. However, when the same button is touched again, i want to remove it from the list..and add it back again if it is touched again. Oh yeah addToOrder currently is global and initialized to true.

Thoughts?

EDIT****per my comments below button is now an instance of a subclass of Button that I wrote so that i can easily keep up with each instance of the button. That solved the issue.

here is the code:

 button.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
        int action = event.getActionMasked();
        //Log.d("Touched Add To Order Button with id of ", button.getId() + ": " + button.getText().toString());
        TextView relativeTitleView;
        ViewGroup relativeGroup = (ViewGroup)v.getParent();
        relativeTitleView = (TextView) relativeGroup.getChildAt(0);
        //Log.d("Add To Order Button Touched", relativeTitleView.getText().toString());

           /*if(action ==MotionEvent.ACTION_DOWN){                          
            addToOrder = (addToOrder) ? true : false;
            if(addToOrder)
                dbAccess.addToOrder(relativeTitleView.getText().toString());
            else
                dbAccess.removeFromOrder(relativeTitleView.getText().toString());
            }
           else if(action == MotionEvent.ACTION_UP){
                addToOrder = !addToOrder;

            }*/

           if(action == MotionEvent.ACTION_DOWN){
              if(button.getTouchInfo()){
               dbAccess.addToOrder(relativeTitleView.getText().toString());
               button.setTouchInfo(false);
              }
              else {
                dbAccess.removeFromOrder(relativeTitleView.getText().toString());
                button.setTouchInfo(true);
              }
         }

            return false;
        }
    });

If this is the only way items are added/removed from dbAccess, you can just switch based on whether or not it’s already there.

if(dbAccess.contains(relativeTitleView.getText().toString())
   dbAccess.removeFromOrder(relativeTitleView.getText().toString());
else
   dbAccess.addToOrder(relativeTitleView.getText().toString());

Edit: Assuming dbAccess has a contains(), can’t tell what type it is here.
