dependencies {

    implementation 'com.github.pengrad:mapscaleview:1.6.0'

}

```

Include in layout file over map

```xml

    

    

```

With miles or custom style

```xml

```

Update on map changed

```kotlin

val scaleView: MapScaleView = findViewById(R.id.scaleView)

val cameraPosition = map.cameraPosition

// need to pass zoom and latitude

scaleView.update(cameraPosition.zoom, cameraPosition.target.latitude)

```

Full example with subscribing to map events and updating scale view

```kotlin

override fun onMapReady(googleMap: GoogleMap) {

    map = googleMap

    googleMap.setOnCameraMoveListener(this)

    googleMap.setOnCameraIdleListener(this)

}

override fun onCameraMove() {

    val cameraPosition = map.cameraPosition

    scaleView.update(cameraPosition.zoom, cameraPosition.target.latitude)

}

override fun onCameraIdle() {

    val cameraPosition = map.cameraPosition

    scaleView.update(cameraPosition.zoom, cameraPosition.target.latitude)

}

```

Refer to the sample project on how to use scale view with other Android Maps SDK (Mapbox).

## Customization

```java

mapScaleView.setColor(@ColorInt int color)

mapScaleView.setTextSize(float textSize)

mapScaleView.setStrokeWidth(float strokeWidth)

mapScaleView.setTextFont(Typeface font)

// enable/disable white outline, enabled by default

mapScaleView.setOutlineEnabled(false)

mapScaleView.metersAndMiles() // default

mapScaleView.metersOnly()

mapScaleView.milesOnly()

// expand scale bar from right to left, disabled by default

mapScaleView.setExpandRtlEnabled(true)
