                    public void onFocusChange(View v, boolean hasFocus) {
                        // TODO Auto-generated method stub
                        if(hasFocus){
                             Submit.setImageResource(R.drawable.sendchat_over_icon);
                        }else{
                             Submit.setImageResource(R.drawable.sendchat_normal_icon);
                        }
                    }
                });

Try using Selector for setting different images on different states.
