class MyTipDialog private constructor(val context: Activity): Dialog(context, R.style.MyTipTheme) {val resId = ObservableField(0)private val mainHandler = Handler(Looper.getMainLooper())init {setCanceledOnTouchOutside(true)setCancelable(true)window?.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)window?.setBackgroundDrawableResource(Color.parseColor("#00000000"))window?.setWindowAnimations(R.style.myTipDialogAnim)val binding = DataBindingUtil.inflate<MyTipsBinding>(layoutInflater, R.layout.my_tips, null, false)binding.viewModel = thissetContentView(binding.root)}companion object{private var instance: MyTipDialog ? = nullfun getInstance(context: Activity, resId: Int): MyTipDialog {if (instance == null){instance = MyTipDialog (context)}instance?.dismiss()instance?.resId?.set(resId)return instance!!}}override fun dispatchTouchEvent(ev: MotionEvent): Boolean {context.dispatchTouchEvent(ev)return super.dispatchTouchEvent(ev)}override fun show() {super.show()mainHandler.postDelayed({dismiss()}, 2000)}override fun dismiss() {super.dismiss()mainHandler.removeCallbacksAndMessages(null)}
