- BottomDialog 提供了对外暴露的 boxBody（对话框内容布局外层）实例；
- WindowUtil 提供了额外自定义WindowManager.LayoutParams的接口：

```java
WindowUtil.windowSettings = new WindowUtil.WindowSettings() {
    @Override
    public WindowManager.LayoutParams overrideWindowLayoutParamsInterface(Context context, View dialogView, WindowManager.LayoutParams originWindowLayoutParams) {
        //处理 originWindowLayoutParams...
        return originWindowLayoutParams;
    }
};
```
