Android BasicGestureDetect Sample

This sample detects gestures on a view and logs them. In order to try this sample out, try dragging or tapping the text.

Introduction

In this sample, the gestures are detected using a custom gesture listener that extends SimpleOnGestureListener and writes the detected MotionEvent into the log.

In this example, the steps followed to set up the gesture detector are:

1. Create the GestureListener that includes all your callbacks.
2. Create the GestureDetector (SimpleOnGestureListener) that will take the listener as an argument.
3. For the view where the gestures will occur, create an onTouchListener that sends all motion events to the gesture detector.

Pre-requisites

• Android SDK 28
