從調用者 class 捕獲對話框關閉事件

Question

我有一個自定義對話框。 如何從調用對話框的 class 捕獲對話框關閉事件？

class DialogShow {
    companion object {
    fun showDialog() {
      //some logic
      val customDialog = CustomDialog(account, context)
      customDialog.onDismissListener = {
           // here I need to return close event
      }
      customDialog.show(activity,"rawer")
    }
    

 }
}

calss CallDialog{
  DialogShow.showDialog()
  //here I need to catch dialog dismiss
}

我需要從 kotlin 和 Java 類中捕獲此事件。

在你的function中創建一個回調參數，在onDismissListener中調用：

class DialogShow {
  companion object {
    fun showDialog(context: Context, onDismiss: ()->Unit) {
      //some logic
      val customDialog = CustomDialog(account, context)
      customDialog.onDismissListener = {
           onDismiss()
      }
      customDialog.show(context, "rawer")
    }
  }
}

fun foo() {
  DialogShow.showDialog(context) {
    // code that is run after dialog is closed
  }
}
