Problem with Geodatabase Query code

shabbirsiddiqui2 — Mon, 16 Mar 2015 15:07:50 GMT

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());

}

});

}

});

}
