Feature layer selection

This sample demonstrates how to select features in a feature layer.

How to use the sample

Tap on a feature on the map to select it

How it works

The map view provides a way to add a listener to screen taps using the setOnTouchListenermethod. The app uses the MotionEvent passed in to the onSingleTapConfirmed method and creates an envelope around that point based on the tolerance. It then creates an query parameter object and sets it geometry property to the envelope it just created (which will be used to find features within it). It then calls the select features method which takes a query parameters object, this selects the features and also returns the result from which you can inspect the selected features.
