Now, I'm going to create an app that can reserve something. There's three function like menu, reserve, and search. However, I don't know that I should create them as three Activities or just use three views as the function. I want to switch to other function by onclicklistener.

Below is my onClickListener,

private OnClickListener listener = new OnClickListener(){ public void onClick(View v) { switch(v.getId()){ case R.id.fuiButton1: break;

    case R.id.fuiButton2:
       break;

  case R.id.fuiButton3:
       break;
    }
} };

Which is the best choice ?
