Android : Unable to get item in onItemClickListener

In my activity, I am using SimpleAdapter for listView. I have added an image and a textView to display in listView. If I remove image, then list works fine. Means I can click on list item and can goto next Activity. But when I added an image, I am unable to click on List's item. Here is my full code below:
