我已经定义了地图叠加层,并且可以毫无问题地显示标记。当我点击一个时,我现在正试图让一些事情发生,但这个事件似乎永远不会触发。我确定我错过了一些明显的东西......
public class MapBlobCollection extends ItemizedOverlay<OverlayItem> {
@SuppressWarnings("serial")
public class ItemTappedEvent extends EventObject
{
public ItemTappedEvent(int itemIndex) {
super(itemIndex);
}
}
private ArrayList<OverlayItem> myOverlays ;
public MapBlobCollection(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
myOverlays = new ArrayList<OverlayItem>();
populate();
}
public void addOverlay(OverlayItem overlay){
myOverlays.add(overlay);
populate();
}
@Override
protected OverlayItem createItem(int i) {
return myOverlays.get(i);
}
// Removes overlay item i
public void removeItem(int i){
myOverlays.remove(i);
populate();
}
// Returns present number of items in list
@Override
public int size() {
return myOverlays.size();
}
public void addOverlayItem(OverlayItem overlayItem) {
myOverlays.add(overlayItem);
populate();
}
public void addOverlayItem(int lat, int lon, String title) {
try {
GeoPoint point = new GeoPoint(lat, lon);
OverlayItem overlayItem = new OverlayItem(point, title, null);
addOverlayItem(overlayItem);
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
@Override
protected boolean onTap(int index) {
super.onTap(index);
Log.d("TESTING","Triggering tap event on " + Integer.toString(index));
EventManager.triggerEvent(this, new ItemTappedEvent(index));
return true;
}
}
基本上,调试日志条目不会被写入,事件也不会触发。
此外,我的地图视图本身并没有平移(应该是它,没有我的任何额外代码吗?),尽管设置了 setBuitInZoomControls(true),但这些也没有出现......所以也许地图视图本身有问题?
mapview 在布局中定义为:
<com.google.android.maps.MapView
android:id="@+id/indexMapView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:apiKey="@string/mapskey_release"/>
而且我没有覆盖任何平局事件或任何东西......
