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

declare variable as

boolean isOddClicked = true;

And update your click listener as

button1.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            //Do stuff here for chnaging background of button
            if(isOddClicked) {
                button1.setBackgroundResource(R.drawable.detailpressed);
                isOddClicked = false;
            } else {
                button1.setBackgroundResource(R.drawable.detailpressed_SECOND_IMAGE);
                isOddClicked = true;
            }

            //Do your task
            Chapter_sync.add(chapid);
        }

NOTE: If your requirement moves between two images then you can use toggle button and customize it. It will work for same as your requirement.
