Android自定义Dialog弹窗

核心思想就是通过Dialog的构造函数来创建Dialog,然后给Dialog设置自定义布局

fun showAlertDialog(context: Context, title: String, message: CharSequence, positive: String, negative: String, cmListener: ConfirmListener?, clListener: CancelListener?): Dialog {

        val dialog = Dialog(context, R.style.KfDialog)

        val contentView = LayoutInflater.from(context).inflate(R.layout.kf_dialog, null)
        val contentTv = contentView.findViewById(R.id.dialog_content)
        val titleTv = contentView.findViewById(R.id.dialog_title)
        val negativeTv = contentView.findViewById(R.id.dialog_negative)
        val positiveTv = contentView.findViewById(R.id.dialog_positive)

        contentTv.text = message
        titleTv.text = title
        negativeTv.text = negative
        positiveTv.text = positive

        negativeTv.setOnClickListener {
            clListener?.onCancel()
            dialog.dismiss()
        }

        positiveTv.setOnClickListener {
            cmListener?.onConfirm()
            dialog.dismiss()
        }
        dialog.setCancelable(false)
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
        dialog.setContentView(contentView)
        dialog.show()
        return dialog
    }

其中style是Dialog弹窗的样式,在styles.xml里面定义,比如:
