I implemented a like function which is similar to the Likening of Facebook. If you already liked a post then a particular imageview will be shown. on clicking on the button will reduce the like count or increase and another imageview will shown instead of previous one (toggling is perform in here).on clicking on the image the like status will post on server and new count will receive from the server as response and it will shown.It is not performing properly.Some times if i scroll up and down the list view then the liking function may work for one time after that it will stuck till scroll up and down again.Can anyone help me?Kindly ask me if you don't understand it.
