        @Override
        public boolean onItemLongClick(AdapterView<?> adapterview, View arg1,
                int arg2, long arg3) {
            LinearLayout view=(LinearLayout) mItemListView.getChildAt(arg2);

My adapter is extending BaseAdapter

Answer 1

Use View that is passed to your onItemLongClick(AdapterView<?> adapterview, View arg1,
int arg2, long arg3) method. For example

mItemListView.setOnItemLongClickListener(new OnItemLongClickListener() {

    @Override
    public boolean onItemLongClick(AdapterView<?> adapterview, View arg1,
            int arg2, long arg3) {
          arg1.setVisibility(View.VISIBLE);
          return false;
    }
});
