How to customize the places UI ?

Hello,
I'm using the places plugin of that library.
I'm using it in a dilaog: https://docs.mapbox.com/android/plugins/overview/places/#display-as-a-fragment

Now I have 2 problems:

1- I want to know how could I set focus dynamically to the search EditText there ?
2- How could I change the hint text of the search editText ?

On image below, The search input has not focus while the keyboard is shown:

Thanks too much.

检查 Android fragment 文档中链接的 Places 插件实现，从 dialog 或 fragment 入口点及其搜索 EditText 开始。验证 focus 和提示文本的配置方式，然后记录受支持的自定义路径，或确定缺少哪些信息。
