I'm having a hard time trying to get layers hiding/unhiding working properly. I just took "HelloWorld" sample code and tweaked it a little just to hide all layers before adding to MapView and... it desn't work! layers is always visible:
public class HelloWorld extends Activity {
MapView mMapView = null;
ArcGISTiledMapServiceLayer tileLayer;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Retrieve the map and initial extent from XML layout
mMapView = (MapView) findViewById(R.id.map);
/* create a @ArcGISTiledMapServiceLayer */
tileLayer = new ArcGISTiledMapServiceLayer("http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer");
tileLayer.setOnStatusChangedListener(new OnStatusChangedListener() {
private static final long serialVersionUID = 1L;
public void onStatusChanged(Object source, STATUS status) {
debug("LAYER STATUS CHANGE: source=" + source.toString() + " status=" + status);
if (status == STATUS.INITIALIZED) {
for (ArcGISLayerInfo layer : ((ArcGISTiledMapServiceLayer) source).getLayers()) {
layer.setVisible(false);
debug(" Hiding Layer:" + layer);
}
// Add tiled layer to MapView
mMapView.addLayer((ArcGISTiledMapServiceLayer) source);
}
}
});
mMapView.setOnStatusChangedListener(new OnStatusChangedListener() {
private static final long serialVersionUID = 1L;
public void onStatusChanged(Object source, STATUS status) {
debug("MAP STATUS CHANGE: source=" + source.toString() + " status=" + status);
if (status == STATUS.LAYER_LOADED && (source == tileLayer)) {
for (ArcGISLayerInfo layer : ((ArcGISTiledMapServiceLayer) source).getLayers()) {
debug(" Layer:" + layer);
}
}
}
});
}
@Override
protected void onPause() {
super.onPause();
mMapView.pause();
}
@Override
protected void onResume() {
super.onResume();
mMapView.unpause();
}
private void debug(String message) {
if (BuildConfig.DEBUG) Log.d("MY_DEBUG", message);
}
}
And here's the output:
MY_DEBUG LAYER STATUS CHANGE: source=com.esri.android.map.ags.ArcGISTiledMapServiceLayer@4129ada0 status=INITIALIZED
MY_DEBUG Hiding Layer:ArcGISLayerInfo [name=World Street Map, id=0, visible=false, minScale=0.0, maxScale=0.0,isShowLegend=true]
MY_DEBUG MAP STATUS CHANGE: source=com.esri.android.map.MapView@4128c698 status=INITIALIZED
MY_DEBUG MAP STATUS CHANGE: source=com.esri.android.map.ags.ArcGISTiledMapServiceLayer@4129ada0 status=LAYER_LOADED
MY_DEBUG Layer:ArcGISLayerInfo [name=World Street Map, id=0, visible=false, minScale=0.0, maxScale=0.0,isShowLegend=true]
It says that layer has visibility set to false although I can still see it on the screen. I have already tried a much simpler code with only one listener attached to mMapView - same result.Any help or thought would be much appreciated! 🙂
