Android 简易的自定义确认弹框AlertDialog

使用方式/构造函数参数解释:

参数一:上下文; 参数二:标题; 参数三:内容; 参数四:确认按钮点击回调

    CustomDialog(this, "清空输入", "确定要清空已输入内容吗？", object : CustomDialog.ClickCallBack {
                override fun onYesClick(dialog: CustomDialog) {
                    //点击确认按钮后具体操作
                    dialog.dismiss()
                }

            }).show()

自定义Dialog代码:

/**
 * Created by Xinghai.Zhao
 * 自定义选择弹框
 */
@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)
        //设置点击别的区域不关闭页面
        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)
    }
}
