How to get a listener for many Feature Layers in ArcGIS Android? -

i have 2 feature layers added map can see when display mapview. however, it's last added feature layer can processed touch listener. cannot figure out how make features layers taken account touch listener.

my goal differentiate click on carto_etare's feature click on carto_pt_eau's one.

any appreciated.

mgeodatabase = new geodatabase(mgeodb); // load geodatabase mgeodatabase.loadasync(); // add feature layer geodatabase arcgismap mgeodatabase.adddoneloadinglistener(new runnable() {     @override     public void run() {         (geodatabasefeaturetable geodbtable : mgeodatabase.getgeodatabasefeaturetables()){              arraylist<string> list_of_tables = new arraylist<string>();             list_of_tables.add("carto_etare");             list_of_tables.add("carto_pt_eau");             set<string> set = new hashset<string>(list_of_tables);             if (set.contains(geodbtable.gettablename())) {                  mfeaturelayer = new featurelayer(geodbtable);                 mfeaturelayer.setlabelsenabled(true);                 mfeaturelayer.setselectionwidth(10);                  //featurelayer.selectfeatures();                 mmap.getoperationallayers().add(mfeaturelayer);                 mmapview.setmap(mmap);                  // set on touch listener listen click events                 mmapview.setontouchlistener(new defaultmapviewontouchlistener(mainactivity.this, mmapview) {                     @override                     public boolean onsingletapconfirmed(motionevent e) {                         // point clicked , convert point in map coordinates                         point clickpoint = mmapview.screentolocation(new android.graphics.point(math.round(e.getx()), math.round(e.gety())));                         int tolerance = 10;                         double maptolerance = tolerance * mmapview.getunitsperdensityindependentpixel();                          // create objects required selection query                         envelope envelope = new envelope(clickpoint.getx() - maptolerance,                                 clickpoint.gety() - maptolerance,                                 clickpoint.getx() + maptolerance,                                 clickpoint.gety() + maptolerance,                                 mmap.getspatialreference());                         queryparameters query = new queryparameters();                         query.setgeometry(envelope);                          // call select features                         mfuture = mfeaturelayer.selectfeaturesasync(query, featurelayer.selectionmode.add);                         // add done loading listener fire when selection returns                         mfuture.adddonelistener(new runnable() {                             @override                             public void run() {                                 try {                                     //call on future result                                     featurequeryresult result = mfuture.get();                                     // create iterator                                     iterator<feature> iterator = result.iterator();                                     feature feature;                                     while (iterator.hasnext()) {                                         feature = iterator.next();                                         map<string, object> attributes = feature.getattributes();                                                                                     if(feature.getfeaturetable().gettablename().equals("carto_pt_eau")) {                                             toast.maketext(getapplicationcontext(), long.tostring((long)attributes.get("id_pt_eau")), toast.length_short).show();                                         }                                         else if(feature.getfeaturetable().gettablename().equals("carto_etare")) {                                             mpdffilename = (string) attributes.get("cod");                                          }                                     }                                 } catch (exception e) {                                     log.e(getresources().getstring(r.string.app_name), "select feature failed: " + e.getmessage());                                 }                             }                         });                         return super.onsingletapconfirmed(e);                     }                 });             }          }     } }); 

your current code select whatever features within mfeaturelayer per line here

mfuture = mfeaturelayer.selectfeaturesasync(query, featurelayer.selectionmode.add); 

which getting overwritten each time within loop on geodatabase tables it's holding whatever layer added last.

i think identify or 1 of overloads might more suited purposes.

some quick example usage code is:

@override public boolean onsingletapconfirmed(motionevent e) {   android.graphics.point screenpoint = new android.graphics.point((int) e.getx(), (int) e.gety());    final listenablefuture<list<identifylayerresult>> identifyfuture = mmapview       .identifylayersasync(screenpoint, 10, false, 10);   identifyfuture.adddonelistener(new runnable() {     @override public void run() {       try {         list<identifylayerresult> identifylayerresultlist = identifyfuture.get();         //if point identify occurs @ contains points both layers, should return 2 results, 1 each layer         log.d("identifysize", string.valueof(identifylayerresultlist.size()));         (identifylayerresult result : identifylayerresultlist) {           layercontent layer = result.getlayercontent();           //do whatever want layer           //the features retrieved through result.getelements()          }       } catch (interruptedexception | executionexception e1) {         e1.printstacktrace();       }     }   });   return super.onsingletapconfirmed(e); }
