在下面的CustomMap.java类中，我想自定义代码，以便我可以添加地理位置数组，多个itemisedOvelay，如CustomMap Part 2中那样。
public class CustomMap extends MapActivity {
MapView mapView;
List<Overlay> mapOverlays;
Drawable drawable;
Drawable drawable2;
CustomItemizedOverlay<CustomOverlayItem> itemizedOverlay;
CustomItemizedOverlay<CustomOverlayItem> itemizedOverlay2;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapOverlays = mapView.getOverlays();
// first overlay
drawable = getResources().getDrawable(R.drawable.marker);
itemizedOverlay = new CustomItemizedOverlay<CustomOverlayItem>(drawable, mapView);
GeoPoint point = new GeoPoint((int)(51.5174723*1E6),(int)(-0.0899537*1E6));
CustomOverlayItem overlayItem = new CustomOverlayItem(point, "Tomorrow Never Dies (1997)",
"(M gives Bond his mission in Daimler car)",
"http://ia.media-imdb.com/images/M/MV5BMTM1MTk2ODQxNV5BMl5BanBnXkFtZTcwOTY5MDg0NA@@._V1._SX40_CR0,0,40,54_.jpg");
itemizedOverlay.addOverlay(overlayItem);
GeoPoint point2 = new GeoPoint((int)(51.515259*1E6),(int)(-0.086623*1E6));
CustomOverlayItem overlayItem2 = new CustomOverlayItem(point2, "GoldenEye (1995)",
"(Interiors Russian defence ministry council chambers in St Petersburg)",
"http://ia.media-imdb.com/images/M/MV5BMzk2OTg4MTk1NF5BMl5BanBnXkFtZTcwNjExNTgzNA@@._V1._SX40_CR0,0,40,54_.jpg");
itemizedOverlay.addOverlay(overlayItem2);
mapOverlays.add(itemizedOverlay);
// second overlay
drawable2 = getResources().getDrawable(R.drawable.marker2);
itemizedOverlay2 = new CustomItemizedOverlay<CustomOverlayItem>(drawable2, mapView);
GeoPoint point3 = new GeoPoint((int)(51.513329*1E6),(int)(-0.08896*1E6));
CustomOverlayItem overlayItem3 = new CustomOverlayItem(point3, "Sliding Doors (1998)",
"(interiors)", null);
itemizedOverlay2.addOverlay(overlayItem3);
GeoPoint point4 = new GeoPoint((int)(51.51738*1E6),(int)(-0.08186*1E6));
CustomOverlayItem overlayItem4 = new CustomOverlayItem(point4, "Mission: Impossible (1996)",
"(Ethan & Jim cafe meeting)",
"http://ia.media-imdb.com/images/M/MV5BMjAyNjk5Njk0MV5BMl5BanBnXkFtZTcwOTA4MjIyMQ@@._V1._SX40_CR0,0,40,54_.jpg");
itemizedOverlay2.addOverlay(overlayItem4);
mapOverlays.add(itemizedOverlay2);
final MapController mc = mapView.getController();
mc.animateTo(point2);
mc.setZoom(16);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
}
代码第2部分：
这不是代码，而是我想要如何进行更改的一点逻辑。总而言之，我尝试使CustomMap.java灵活，以便我可以通过数组向它添加多个点和信息。
public class CustomMap extends MapActivity {
MapView mapView;
List<Overlay> mapOverlays;
Drawable drawable;
Drawable drawable2;
CustomItemizedOverlay<CustomOverlayItem> itemizedOverlay[];
CustomItemizedOverlay<CustomOverlayItem> itemizedOverlay2[];
double[]lat,lon;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapOverlays = mapView.getOverlays();
// first overlay
drawable = getResources().getDrawable(R.drawable.marker);
itemizedOverlay = new CustomItemizedOverlay<CustomOverlayItem>(drawable, mapView);
GeoPoint point[] = new GeoPoint((int)(lat*1E6),(int)(lon*1E6));
CustomOverlayItem overlayItem = new CustomOverlayItem(point, "Tomorrow Never Dies (1997)",
"(M gives Bond his mission in Daimler car)",
"http://ia.media-imdb.com/images/M/MV5BMTM1MTk2ODQxNV5BMl5BanBnXkFtZTcwOTY5MDg0NA@@._V1._SX40_CR0,0,40,54_.jpg");
itemizedOverlay.addOverlay(overlayItem);
mapOverlays.add(itemizedOverlay);
final MapController mc = mapView.getController();
mc.animateTo(point2);
mc.setZoom(16);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
}
答案 0 :(得分：0)
设置Overlay mapview.getOverlays（）。add（new SitesOverlay（））;
自定义弹出窗口
的 SitesOverlay.class
private class SitesOverlay extends ItemizedOverlay<CustomItem> {
private List<CustomItem> items;
private View view = null;
public SitesOverlay() {
super(null);
items = new ArrayList<CustomItem>();
items.add(new CustomItem(pt, busName, "Bendigo", marker));
boundCenter(marker);
populate();
}
@Override
protected CustomItem createItem(int i) {
return (items.get(i));
}
@Override
public void draw(Canvas canvas, MapView mapView, boolean shadow) {
if (!shadow) {
super.draw(canvas, mapView, false);
}
}
@Override
public int size() {
return (items.size());
}
public void refresh() {
populate();
}
public void clear() {
items.clear();
resetLastFocuesIndex();
}
public void resetLastFocuesIndex() {
setLastFocusedIndex(-1);
}
@Override
protected boolean onTap(final int index) {
if (view != null) {
view.setVisibility(View.GONE);
getMapView().removeView(view);
getMapView().invalidate();
view = null;
}
view = getLayoutInflater().inflate(R.layout.balloon_overlay, null);
LinearLayout layout = (LinearLayout) view
.findViewById(R.id.balloon_main_layout);
layout.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
view.setBackgroundResource(R.drawable.balloon_overlay_bg_selector);
ImageView image = (ImageView) view
.findViewById(R.id.balloon_disclosure);
TextView text = (TextView) view
.findViewById(R.id.balloon_item_title);
text.setText(items.get(index).getTitle());
Projection projection = getMapView().getProjection();
Point point = new Point();
projection.toPixels(items.get(index).getPoint(), point);
int x = (int) (view.getWidth() / 2f);
int y = -marker.getIntrinsicHeight() - 3;
MapView.LayoutParams lp = new MapView.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT, items.get(index)
.getPoint(), x, y + 50,
MapView.LayoutParams.BOTTOM_CENTER);
getMapView().removeView(view);
getMapView().invalidate();
getMapView().addView(view, lp);
getMapView().invalidate();
view.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
if (!items.isEmpty()) {
if (view != null) {
view.setVisibility(View.GONE);
getMapView().invalidate();
// Intent intent=new Intent(MapLocationActivity.this,);
}
}
getMapView().invalidate();
}
});
return true;
}
}
class CustomItem extends OverlayItem {
Drawable marker = null;
CustomItem(GeoPoint pt, String name, String snippet, Drawable marker) {
super(pt, name, snippet);
this.marker = marker;
}
@Override
public Drawable getMarker(int stateBitset) {
Drawable result = marker;
setState(result, stateBitset);
return (result);
}
}
如果有多个标记，那么
for (int i = 0; i < arrayList.size(); i++) {
slat = Double.parseDouble(arrayList.get(i).getLat());
vlong = Double.parseDouble(arrayList.get(i).getvLong());
pt = new GeoPoint((int) (slat * 1E6), (int) (vlong * 1E6));
Log.e("lat long", "--- "+slat);
MapviewActivity.this.mc.animateTo(pt);
items.add(new CustomItem(pt, arrayList.get(i).getBuissnessName(), "Bendigo", marker));
boundCenter(marker);
}
执行此操作。
