<color name="set_on_color">#333333</color>
<color name="set_off_color">#666666</color>

변경하고자 하는 소스는 아래와 같습니다.

 public boolean onTouch(View v, MotionEvent event) {
  if (event.getAction() == MotionEvent.ACTION_DOWN) {
           
   switch (v.getId()) {
   case R.id.EditText01: 
    editText01.setTextColor(R.color.set_on_color);
    editText01.setBackgroundResource(R.drawable.clock_start_on);
    editText02.setTextColor(R.color.set_off_color);
    editText02.setBackgroundResource(R.drawable.clock_end_off);
    
    timeSetting = CommonIds.START_TIME_SETTING;
    break;
   case R.id.EditText02: 
    editText02.setTextColor(R.color.set_on_color);
    editText02.setBackgroundResource(R.drawable.clock_end_on);
    editText01.setTextColor(R.color.set_off_color);
    editText01.setBackgroundResource(R.drawable.clock_start_off);
    
    timeSetting = CommonIds.END_TIME_SETTING;
    break;
   }
  }
  return false;
 }

setBackgroundResource 잘 적용되어서 바뀌는데
.setTextColor 는 적용이 안됩니다....고수님들의 조언 부탁드립니다..ㅠㅠ
