title: Database to ListView - Filter out entries
body: <p>I have a SQLite database and I'm getting a ListView from the database through a SimpleCursorAdapter. This is the existing code:</p>
  
  <pre><code>Cursor c = mDatabase.query(
              "database",
              bla = new String[]{
                      "_id",
                      "title",
                      "message",
                      "time",
                      "date",
                      "done"
              },
              null, null, null, null, null);
      startManagingCursor(c);
  
      SimpleCursorAdapter listAdapter =
              new SimpleCursorAdapter(this,
                      R.layout.list_item, c,
                      new String[]{"title", "message", "time", "date"},
                      new int[]{R.id.txtv_title, R.id.txtv_message, R.id.txtv_time, R.id.txtv_date}
              );
      setListAdapter(listAdapter);
  </code></pre>
  
  <p>This works as intended and I'm getting my ListView.
  Now I want that if the "done" field in my database contains the string "false" (instead of "true" ...), this row doesn't get into the ListView. </p>
  
  <p>How can I do this?
  Thanks in advance!</p>
