i have same error and i found that convertView= LayoutInflater.from(mContext).inflate(R.layout.dayadapter,null); // | layOutName |
layout name of my app is different from ben sir.

so i will suggest u to check the path of your lay out [ R.layout.XmlName ] to b same to the file u created for custom adapter in layout folder ur XmlName must b different from this [ check it in class where u extend baseadapter class and in getview in if(convertView==null){ //mostly 2nd line of this block u have to check layout name; }

]

this will suerly help u out.
