## Extend your theme from .Dialog.Alert

```xml
<style name="YOUR_THEME_NAME" parent="@style/Theme.AppCompat.Light.Dialog.Alert">
    <!--your theme here-->
</style>
```

**Do not extend your theme from .Dialog, if you want your dialog to match parent/window's width.**

```xml
<style name="YOUR_THEME_NAME" parent="@style/Theme.AppCompat.Light.Dialog.Alert">
    <!--your theme here-->
</style>
```
