how to refresh a list view when the activity still in active mode
<p>I have a ListView that contains some data from sqllite table.
the table is updated by some other process, and I would like to
refresh it's data.</p>

<p>I tried invalidate,
tried doing setAdapter() again and again,
nothing helped. it does not reload.
Should I close the adapter somehow and re-open it?</p>

<p>The strange thing is that if I open another activity, then go back -
it WILL refresh itself.</p>
