高德无法显示Marker

[NeverMore93]

我在Marker上下都用Toast显示Marker属性，可是就是显示不出Marker
code=java] private void showOnePoint(int pos)
{
Toast.makeText(CarJianguanActivity.this, pos+"", Toast.LENGTH_LONG).show();

final LatLng latlng = new LatLng(Double.parseDouble(carmap.get(pos + "").get("Latitude").toString()),
Double.parseDouble(carmap.get(pos + "").get("Longitude").toString()));

Toast.makeText(CarJianguanActivity.this, Double.parseDouble(carmap.get(pos + "").get("Latitude").toString())+"xxx"
+Double.parseDouble(carmap.get(pos + "").get("Longitude").toString()), Toast.LENGTH_LONG).show();

Marker marker= aMap.addMarker(new MarkerOptions().position(latlng).icon(carmap.get(pos + "").get("CarStatus").toString().equals("1") ? markonline : mark));


// aMap.addMarker(new MarkerOptions().position(latlng).icon(meitu));



text_Diaplay.setText(carmap.get(pos + "").get("CarNumber").toString() + ":" + carmap.get(pos + "").get("Position").toString() + "\r\n速度：" + carmap.get(pos + "").get("Speed").toString() + "Km/h");

new Timer().schedule(new TimerTask() {

@Override
public void run() {
// TODO Auto-generated method stub
aMap.moveCamera(CameraUpdateFactory.newLatLng(latlng));
}
}, 500);
}[/code]
