Delete entry from file


Delete entry from file

This might help you If you open with w+, the file will be emptied.
Instead, use r+. if you do so, you'll have to rewind your file before writing and maybe truncate it afterwards.
code :
def remove_entry_from_file(entry_id):
    f = open(file.txt, 'r+')
    data = f.read()
    new_data = re.sub(entry_id + '[, ]*', '' ,data)
    f.seek(0)
    f.write(new_data)
    f.truncate()
    f.close()

Hope that helps Since you have stored your selection into "item" object then in deleteFile() method you need to retreive the file path from that object, for that to work add the line:
code :
  lv = new ListViewAdapter(this, R.layout.row, videoItems);
  setListAdapter(lv);
