Gesture Interaction

[Navinfo Navigation SDK for Android] provides a rich set of gestures to help developers interact with maps. Gesture operations mainly include zoom gestures, swipe gestures, and rotation gestures.

Slide gesture

Use your finger to hold the map and drag the map to pan or swipe the map.

Zoom gesture

You can pinch or stretch with two fingers and double-click on the map to change the zoom level of the map.

Rotate gesture

You can rotate on the map with two fingers and you can rotate the 3D vector map.

Handshake switch

The switch and query of the gesture can be implemented by code, examples are as follows:

                mMapRenderer.enableOptionalGesture(int gesture, boolean enable); // Open the close gesture
                mMapRenderer.isOptionalGestureEnabled(int gesture); // Query gesture is open
            

gesture: Gesture type, see MapRenderer.OptionalGesture class, see the following table

enable: gesture switch, true means open gesture, false close gesture
