以及我如何将此文件添加到地图中：
public static void parseFile(Context context, String id, GoogleMap map) throws IOException, XmlPullParserException {
String file = id + HomeActivity.KML;
KmlLayer layer = createKmlLayer(map, file);
layer.addLayerToMap();
}
private static KmlLayer createKmlLayer(GoogleMap map, String kmlFile) {
KmlLayer layer = null;
try {
InputStream inputStream = GeofenceApplication.getContext().getAssets().open(kmlFile);
layer = new KmlLayer(map, inputStream, GeofenceApplication.getContext());
} catch (Exception exception) {
logger.error("ERROR", exception);
}
return layer;
}
当我运行该代码时，我没有看到该行。 那么我犯了错误？
