今天的文章水一把
抽一个方法设置窗口的属性

 fun setWindowConstraints(
    context: Context,
    window: Window,
    view: DialogLayout,
    maxWidth: Int?
  ) {
    if (maxWidth == 0) {
      // Postpone
      return
    }
    window.setSoftInputMode(LayoutParams.SOFT_INPUT_ADJUST_RESIZE)
    val lp = LayoutParams()
        .apply {
          copyFrom(window.attributes)
          width = LayoutParams.MATCH_PARENT
          height = LayoutParams.MATCH_PARENT
        }
    window.attributes = lp
  }

然后，重写对话框的show方法

 override fun show() {
    setWindowConstraints()
     
    super.show()
    
  }
