xml布局：

<com.nxwna.leartime.ui.clock.FlipLayoutandroid:id="@+id/flip_1"android:layout_width="match_parent"android:layout_height="match_parent"myFlip:flipTextColor="#ff5d6b77"myFlip:flipTextSize="78dp" />

用法：

先初始化數(shù)據(jù)

flip_1.flip(hourTime, 24, TimeTAG.hour) flip_2.flip(minTime, 60, TimeTAG.min) flip_3.flip(secondTime, 60, TimeTAG.sec) private var oldHour: Int = 0 private var oldminute: Int = 0 private var oldsecond: Int = 0

計(jì)時(shí)功能

fun doCountDown(time: Long) {val hour1: Int = TimeUtils.getHours(time / 1000).toInt()val minute1: Int = TimeUtils.getMins(time / 1000).toInt()val second1: Int = TimeUtils.getSeconds(time / 1000).toInt()val hour = oldHour - hour1val minute = oldminute - minute1val second = oldsecond - second1oldHour = hour1oldminute = minute1oldsecond = second1if (hour >= 1 || hour == -23) {flip_1.smoothDownFlip(1, 24, TimeTAG.hour, false, hour1)}if (minute >= 1 || minute == -59) {flip_2.smoothDownFlip(1, 60, TimeTAG.min, false, minute1)}if (second >= 1 || second == -59) {flip_3.smoothDownFlip(1, 60, TimeTAG.sec, false, second1)} }
