How to toggle background image on button click?

Question

I have this code:

button1.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
          


        

Answer 1

you can take a variable

int i=0;

it will increase with every click.

if(i%2==0)
   set one image
else 
   set another image
