    <p>I want to display more points on a map. I want to do that with a "for". My problem is that only the last point is displayed, because variables: point and overlayItem are overwritten each time. How can I make a unique name for this variables?</p> <pre><code> List&lt;Statia&gt; arrStatia = datasourceStatia.getAllStatias(); for (Statia s : arrStatia) { String[] arrCoordonate = s.getCoord().split(","); GeoPoint point = new GeoPoint((int)(Double.parseDouble(arrCoordonate[1])),(int)(Double.parseDouble(arrCoordonate[0]))); OverlayItem overlayItem = new OverlayItem(point, Double.parseDouble(arrCoordonate[1]) + "", Double.parseDouble(arrCoordonate[0]) +""); itemizedOverlay.addOverlay(overlayItem); mapOverlays.add(itemizedOverlay); mapView.postInvalidate(); Log.v("xxx", s.getCoord()); } public class Statia { private long id; private String statia; private long idruta; private String coord; private String program; public long getId() { return id; } public void setId(long id) { this.id = id; } public long getIdRuta() { return idruta; } public void setIdRuta(long idruta) { this.idruta = idruta; } public String getStatia() { return statia; } public void setStatia(String statia) { this.statia = statia; } public void setCoord(String coord) { this.coord = coord; } public String getCoord() { return coord; } public void setProgram(String program) { this.program = program; } public String getProgram() { return program; } // Will be used by the ArrayAdapter in the ListView @Override public String toString() { return statia; } } public List&lt;Statia&gt; getAllStatias() { List&lt;Statia&gt; statias = new ArrayList&lt;Statia&gt;(); Cursor cursor = database.query(DatabaseHelper.statiiTable, allColumns, null, null, null, null, null); cursor.moveToFirst(); while (!cursor.isAfterLast()) { Statia statia = cursorToStatia(cursor); statias.add(statia); cursor.moveToNext(); } // Make sure to close the cursor cursor.close(); return statias; } private Statia cursorToStatia(Cursor cursor) { Statia statia = new Statia(); statia.setId(cursor.getLong(0)); statia.setStatia(cursor.getString(1)); statia.setIdRuta(cursor.getInt(2)); statia.setCoord(cursor.getString(3)); statia.setProgram(cursor.getString(4)); return statia; } </code></pre>

    1. COI think your problem is not point or overlayItem, it should be the itemizedOverlay.addOverlay() or mapOverlay.addOverlay(). What is itemizedOverlay type?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
