直播系統原始碼，簡易的自定義確認彈框AlertDialog實現的相關程式碼

  CustomDialog(this, "清空輸入", "確定要清空已輸入內容嗎？", object : CustomDialog.ClickCallBack {
        override fun onYesClick(dialog: CustomDialog) {
          //點選確認按鈕後具體操作
          dialog.dismiss()
        }

      }).show()

​

自定義Dialog程式碼:

/**
* Created by Xinghai.Zhao
* 自定義選擇彈框
*/
@SuppressLint("InflateParams")
class CustomDialog(context: Context?) : AlertDialog(context){
  var mCallBack: ClickCallBack? = null
  var mTextViewTitle: TextView? = null
  var mTextViewContent: TextView? = null
  constructor(context: Context?, title: String?, content: String?, callBack: ClickCallBack) : this(context) {
    mCallBack = callBack
    if (title != null) mTextViewTitle?.text = title
    if (content != null) mTextViewContent?.text = content
  }
  init {
    val inflate = LayoutInflater.from(context).inflate(R.layout.dialog_custom, null)
    setView(inflate)
    //設定點選別的區域不關閉頁面
    setCancelable(false)
    mTextViewTitle = inflate.findViewById(R.id.dialog_custom_title)
    mTextViewContent = inflate.findViewById(R.id.dialog_custom_content)
    inflate.findViewById<View>(R.id.dialog_custom_yes).setOnClickListener{mCallBack?.onYesClick(this)}
    inflate.findViewById<View>(R.id.dialog_custom_no).setOnClickListener{dismiss()}
  }
  interface ClickCallBack {
    fun onYesClick(dialog:CustomDialog)
  }
}
