Hi ,
I am new in Android Development so i am not able to figure out the problem,
trying to get the result on singletab using offline geodatabase. Following are the code
Its not returning the result and control is not going inside the onCallback method.
Please help me in resolving this .
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// create the path to local tpk
landDataFile = Environment.getExternalStorageDirectory();
offlineDataSDCardDirName = this.getResources().getString(R.string.offline_dir);
filename = this.getResources().getString(R.string.local_tpk);
fileNameGeoDatabase = this.getResources().getString(R.string.local_geodatabase);
// create the url
String basemap = landDataFile + File.separator + offlineDataSDCardDirName + File.separator + filename;
String geodatabasepath = landDataFile + File.separator + offlineDataSDCardDirName + File.separator + fileNameGeoDatabase;
// for accessing the featurelayer using geodatabase
try {
geodatabase = new Geodatabase(geodatabasepath);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
geodatabaseFeatureTable = geodatabase.getGeodatabaseFeatureTableByLayerId(1);
// Create feature layer and add the map into it.
featureLayer = new FeatureLayer(geodatabaseFeatureTable);
// featureLayer.getSelectedFeatures();
featureLayer.setSelectionColor(12828800); // added for identity
featureLayer.setSelectionColorWidth(30); //added for identity
// create the mapview
mMapView = (MapView) findViewById(R.id.map);
// create the local tpk
localTiledLayer = new ArcGISLocalTiledLayer(basemap);
// add the layer
mMapView.addLayer(localTiledLayer);
mMapView.addLayer(featureLayer);
Envelope env = new Envelope(398646.635989773, 2941161.63084675, 399056.211808925, 2941234.25911701);
mMapView.setExtent(env);
// enable panning over date line
mMapView.enableWrapAround(true);
// set Esri logo
mMapView.setEsriLogoVisible(false);
mMapView.setOnStatusChangedListener(new OnStatusChangedListener() {
public void onStatusChanged(Object source, STATUS status) {
// Check to see if map has successfully loaded
if ((source == mMapView) && (status == STATUS.INITIALIZED)) {
// Set the flag to true
mIsMapLoaded = true;
}
}
});
mMapView.setOnSingleTapListener(new OnSingleTapListener() {
@Override
public void onSingleTap(float x, float y) {
// geoDataBaseQuery();
// convert event into screen click
featureLayer.clearSelection();
pointClicked = mMapView.toMapPoint(x, y);
QueryParameters q = new QueryParameters();
// optional
q.setWhere("1=1");
q.setOutSpatialReference(mMapView.getSpatialReference());
q.setReturnGeometry(true);
q.setSpatialRelationship(SpatialRelationship.INTERSECTS);
q.setGeometry(pointClicked);
q.setInSpatialReference(mMapView.getSpatialReference());
// q.setSpatialRelationship(SpatialRelationship.INTERSECTS);
// featureLayer.selectFeatures(q,SelectionMode.NEW,callback);
featureLayer.selectFeatures(q,SelectionMode.NEW, new CallbackListener<FeatureResult>() {
@Override
public void onError(Throwable ex) {
// Highlight errors to the user.
showToast("Error querying FeatureServiceTable");
}
@Override
public void onCallback(FeatureResult objs) {
// If there are no query results, inform user.
if (objs.featureCount() < 1) {
showToast("No results");
return;
}
else {
// Report number of results to user.
showToast("Found " + objs.featureCount() + " features.");
// Iterate the results and select each feature.
for (Object objFeature : objs) {
Feature feature = (Feature) objFeature;
featureLayer.selectFeature(feature.getId());
}
}
}
});
}
});
}
