Not working with empty data list

[lat233]

For the first time the app cannot reach the backend because of network failure, hence the data list for the adapter is empty. The listview is not shown up in the screen so there's no "pull to refresh" nor "tap to refresh" view. As consequence users have no way to refresh the listview to get data again.

For me it's working, it shows TAP.
