我需要一些方法来移动地图视图中道路上的公共汽车图标。我有地理点数组,其中包含公共汽车需要通过的所有坐标经度和纬度点,我还需要沿路线创建一些“位移动画”
我使用 Overlay 类每 1 秒设置一个总线图标
class BusOverlay extends ItemizedOverlay<OverlayItem> {
private Context context = null;
private List<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
private MediaPlayer mediaPop;
public BusOverlay(Drawable defaultMarker, Context context) {
super(boundCenterBottom(defaultMarker));
this.context = context;
}
@Override
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
@Override
public int size() {
return mOverlays.size();
}
public void addOverlayItem(OverlayItem overlayItem) {
mOverlays.add(overlayItem);
populate();
}
public void addOverlayItem(int lat, int lon, String title) {
GeoPoint point = new GeoPoint(lat, lon);
OverlayItem overlayItem = new OverlayItem(point, title, title);
addOverlayItem(overlayItem);
}
public void removeOverlay(OverlayItem overlay) {
mOverlays.remove(overlay);
populate();
}
public void removeOverlayItem(int lat, int lon, String title) {
GeoPoint point = new GeoPoint(lat, lon);
OverlayItem overlayItem = new OverlayItem(point, title, title);
removeOverlay(overlayItem);
}
protected boolean onTap(int index) {
super.onTap(index);
return true;
}
}
在我的活动类中,我使用了 Runable 方法
Drawable busLocationIcon = this.getResources().getDrawable(
R.drawable.bus_location);
final BusOverlay itemizedBusLocartionOverlay = new BusOverlay(
busLocationIcon, this);
int countBus = 0;
myRunnable = new Runnable() {
public void run() {
try {
itemizedBusLocartionOverlay.addOverlayItem((int) (Double
.parseDouble(Main.jsonArrayBus.getJSONObject(
countBus).getString("StopLat")) * 1000000),
(int) (Double.parseDouble(Main.jsonArrayBus
.getJSONObject(countBus).getString(
"StopLon")) * 1000000), "The Bus");
countBus++;
mapView.getOverlays().add(itemizedBusLocartionOverlay);
} catch (NumberFormatException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//Hendler
h.postDelayed(myRunnable, 1000);
}
};
h.postDelayed(myRunnable, 1000);
但是效果不好。。
请帮我。
