Thanks in advance..

Answer 1

i don’t get where is problem

in layout xml add onClick=”onClick” for every button then in Activity ad function

public void onClick(View v) {
  switch(v.getId()){
    case R.id.Button1:
      break;
    case R.id.Button2:
      break;
    case R.id.Button3:
      break;
//....
  }
}

EDIT (coz i can’t add coment to someone else answer:

According to this http://developer.android.com/reference/android/widget/Button.html Zach you’re wrong

However, instead of applying an
OnClickListener to the button in your
activity, you can assign a method to
your button in the XML layout, using
the android:onClick attribute
