# Customize info panel background and additional properties using Navigation View

![The example demonstrates how to add custom action buttons at runtime.](https://docs.mapbox.com/android/ja/assets/ideal-img/navigation-drop-in-ui-infopanel-attributes.549a2f6.480.jpg)

> **Note**
> 
> This example is a part of the [Navigation SDK Examples](https://github.com/mapbox/mapbox-navigation-android-examples). You can find the values for all referenced resources in the [`res`](https://github.com/mapbox/mapbox-navigation-android-examples/tree/main-v2/app/src/main/res) directory. For example, see [`res/values/strings.xml`](https://github.com/mapbox/mapbox-navigation-android-examples/tree/main-v2/app/src/main/res/values/strings.xml) for `R.string.*` references used in this example. The dependencies can be found [here.](https://github.com/mapbox/mapbox-navigation-android-examples/blob/main/app/build.gradle) The examples use View binding.

import androidx.appcompat.app.AppCompatActivity

/**
 * The example demonstrates how to use [ViewStyleCustomization] to customize the peek height,
 * margins and background for the default info panel supplied by Drop-In UI.
 *
 * Before running the example make sure you have put your access_token in the correct place
 * inside [app-preview/src/main/res/values/mapbox_access_token.xml]. If not present then add
 * this file at the location mentioned above and add the following content to it
 *
 * <?xml version="1.0" encoding="utf-8"?>
 * <resources xmlns:tools="http://schemas.android.com/tools">
 *     <string name="mapbox_access_token"><PUT_YOUR_ACCESS_TOKEN_HERE></string>
 * </resources>
 *
 * The example uses replay location engine to facilitate navigation without physically moving.
 *
 * How to use the example:
 * - Start the example
 * - Grant the location permissions if not already granted
 * - Press on the floating button in the bottom right to apply custom styles
