title: When I check a RadioButton in one row in ListView with custom SimpleCursorAdapter, the other row is getting checked too
body: <p>In each row of my <code>ListView</code> I have a <code>RadioGroup</code> with <code>RadioButton</code>s.</p>
  
  <p>From the database I get five rows and when I check the RadioButtons in the first row and then scroll I see that the third row is getting checked too (on screen, not database). </p>
  
  <p>When I check RadioButtons in the second row, the fourth row is getting checked too. </p>
  
  <p>Screen placed a 1,5 rows.</p>
