kotlin学习笔记

class DialogSucceed(context: Context) : AlertDialog(context),
    View.OnClickListener {

    constructor(context: Context?, line: Int?) : this(context!!) {

        tv_grid_num.text = (line.toString() + "-")
    }

    init {
        var layout = LayoutInflater.from(context).inflate(R.layout.dialog_pay_succeed, null)

        setView(layout)

        //设置点击别的区域关闭页面
        setCancelable(true)

        layout.ll_return.setOnClickListener(this)
        layout.tv_go_home.setOnClickListener(this)
    }

    override fun show() {
        val params: WindowManager.LayoutParams = window!!.attributes
        params.width = 700
        params.gravity = Gravity.CENTER
        window!!.attributes = params
        window!!.setBackgroundDrawableResource(android.R.color.transparent)

        super.show()
    }

    override fun onClick(v: View?) {
        when (v) {
            ll_return -> dismiss()
            tv_go_home -> dismiss()
        }
    }

}

调用方法

val  dialog1 = DialogShopSucceed(mContext,1)
dialog1.show()
