Keydown doesn't work

Hi I wanted to populate one textbox from the input of another textbox on every key press, but it doesn't. the code is like this

leftside.setOnKeyListener(new OnKeyListener()
    {

        @Override
        public boolean onKey(View arg0, int arg1, KeyEvent arg2) 
        {
            if(arg2.getAction() == KeyEvent.ACTION_DOWN)
            {
                Log.v("keyevent", "down");
                float value = Float.parseFloat(leftside.getText().toString());
                rightside.setText(String.valueOf(SelectConverter(Float.parseFloat(leftside.getText().toString()))));
            }
            // TODO Auto-generated method stub
            return false;
        }

    });

instead KeyListener

. I think that it is more suitable for achieving your goal, and it is more convenient to work with it.



Here's an example:
