I want to make a app about cell infomation.

I had new a TelephonyManager (tm) inorder to getNeighboringCellInfo.

*List<NeighboringCellInfo> 
neighboringCellInfoList=tm.getNeighboringCellInfo();*
*new 
ArrayAdapter(XXXX.this,R.layout.celllistlayout,neighboringCellInfoList);*


then,set this adapter to the ListView and notifyDataSetChanged.

The backgroud data is changing,but the ListView never.

What should i do to fresh the UI automatically?
