you have use notifydatasetchanged after updating adapter populate new data
if(responsestring.getstcode().equals("0")) { if (name1.size() != 0) { log.d("adpter list", name1.tostring()); //adapter = new autocompleteadapter(topuptransfer.this, r.layout.listview_raw,r.id.desc, name1); adapter = new autocompleteadapter2(topuptransfer.this,r.id.desc, name1); memberview.setadapter(adapter); adapter.notifydatasetchanged(): } }
