I am adding Linear Layout Dynamically within the listitem of the linear layout through the JSON Data.The Problem i am facing is that ,the linear layout are added more than the length of the JSON .How can this issue be solved?

The view are added more than specified by the JSON length in the linearlayout.I am not able to find exact issue.
You should use removeAllViews() on your linearLayout because in case of convertView is no null it already contains views that you've added using addView
viewHolder.receiptLinearLayout.removeAllViews(); // before entering the for loop
You see when you right this line
if (convertView == null) {
} else {
}
You are telling your adapter to recycle the view if already exists so when the first time the view does'nt exists and you use addView on your linearLayout it will add the view according to your json data lenght but when it recycle the view(convertView != null), the views that you added to your LinearLayout are also recycled and without using removeAllViews() on it, it just like your adding the same views again. Hope it's clear :)
