1.代码
1 class NotifyAlertDlg (var callback : ((dlg : NotifyAlertDlg) -> Unit)? = null): DialogFragment() { 2 3 lateinit var binding : NotifyAlertBinding 4 5 fun initBinding(){ 6 binding.notifyDlgClose.setOnClickListener(this::onCloseClicked) 7 binding.notifyAlertOk.setOnClickListener(this::onOpenClicked) 8 } 9 fun onCloseClicked(v : View){ 10 dialog?.dismiss() 11 } 12 fun onOpenClicked(v : View){ 13 callback?.invoke(this) 14 } 15 16 override fun show(transaction: FragmentTransaction, tag: String?): Int { 17 return super.show(transaction, tag) 18 } 19 20 override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? { 21 binding = NotifyAlertBinding.inflate(inflater,container,false) 22 initBinding() 23 return binding.root 24 } 25 26 override fun onActivityCreated(savedInstanceState: Bundle?) { 27 super.onActivityCreated(savedInstanceState) 28 } 29 30 override fun onStart() { 31 context?.let { 32 initDialog(it) 33 } 34 super.onStart() 35 } 36 fun initDialog(context: Context){ 37 dialog?.apply { 38 setCancelable(true) //取消 39 setCanceledOnTouchOutside(true) //点击外部不消失的方法 40 41 } 42 val window = dialog?.window?.apply { 43 setBackgroundDrawableResource(R.color.transparent) //如果不设置背景，有白色的直角边。 44 decorView.setPadding(32,0,32,0) //设置背景后，在layout中的margin失效，在这里设置 45 } 46 if(window == null){ 47 return 48 } 49 val params = window.attributes.apply { 50 width = (window.windowManager.defaultDisplay.width * 0.91f).toInt()//按比例显示 51 height = WRAP_CONTENT 52 gravity = Gravity.CENTER 53 dimAmount = 0.3f //设置Dialog弹出时背景的透明度 54 horizontalMargin = 0f //设置Dialog水平方向的间距 55 verticalMargin = 0f //设置Dialog垂直方向的间距 56 // verticalWeight = 0.5f 57 // horizontalWeight = 0.5f 58 x = 0 //设置Dialog显示时X轴的坐标,具体屏幕X轴的偏移量 59 y = 0 //设置Dialog显示时Y轴的坐标,距离屏幕Y轴的偏移量 60 alpha = 1f //设置Dialog的透明度 61 windowAnimations = 0 //设置Dialog显示和消失时的动画 62 63 } 64 window.attributes = params as WindowManager.LayoutParams? 65 } 66 }

3.使用
1 fun notifyToast(){ 2 val dlg = NotifyAlertDlg().apply { callback = this@SettingFrgmt::onDialogClicked } 3 dlg.show(requireFragmentManager(),"NotifyDlg") 4 }
