other way is what jaswant has suggested, but i wouldnt use it..... not
object oriented...i persoanlly dont like functions which has too many ifs
then elses, in your case it may go upto 100
also if your requirment is just changing a label...then i would say do
somethin glike this
Class MyButton extends Button implemnts ClickListener{
TextView textView;
public MyButton (){
this.textView = tv;
}
public MyButton (TextView tv){
this.textView = tv;
}
public void onButtonClick(View view){
tv.setText("Whatever you want to change");
}
}
Now inject your textView either by Constructor or create a setter and use
that. Now you will write only one ClickListener and all will work same way.
Use this if all buttons have same functionality. And this is quite basic
pattern you can modify it as per your other requirments.
