Pls help me.

I can do it, here is the code

private void setLikeAction() {
    btnLike.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            HashMap quote = new HashMap();
            quote.put("objectId", quoteId);
            quote.put("quoteLikeCount", likeConut += 1);

            Backendless.Persistence.of(Constants.TABLE_QUOTE).save(quote, new AsyncCallback&lt;Map&gt;() {
                @Override
                public void handleResponse(Map response) {
                    btnLike.setImageResource(R.drawable.ic_action_like_on);
                    Toast.makeText(getApplicationContext(), R.string.liked, Toast.LENGTH_SHORT).show();

                }

                @Override
                public void handleFault(BackendlessFault fault) {
                    Toast.makeText(getApplicationContext(), fault.toString(), Toast.LENGTH_SHORT).show();

                }
            });
        }
    });

}
