title: Reset all primary key fields when row is deleted
body: <p>In my android app I have a methods which deletes a row in a SQLite Database.</p>
  
  <p>Here is the code :</p>
  
  <pre><code>public void deleteRow(int id, MyDatabase db, String table) {
          SQLiteDatabase writableDB = db.getWritableDatabase();
          writableDB
                  .delete(table, "_id = ?", new String[] { String.valueOf(id) });
          writableDB.close();
      }
  </code></pre>
  
  <p>When I execute this method, the row under that id is deleted, and it's content stays empty. I need to replace that row with the next and so on. (Reset primary keys?) Help?</p>
