Android 时间范围搜索栏 [英] Android Time Range Seek Bar

问题描述

我想允许我的应用的用户修剪视频中的特定部分.而且我正在寻找一种解决方案，可以帮助我使用两个拇指(最大和最小时间)制作时间选择滑块.

I want to allow the user of my app to trim a specific part from a video. And i'm looking for a solution that can help me make a time selection slider with two thumbs(Max and Min time).

这是我想要实现的示例.

This is a sample of what i want to achieve .

我知道已经有一些库可以提供帮助:

I know that there is already some librarys that can help:

android-range-seek-bar

材料范围栏

但它们只适用于浮点数和整数.我的问题是如何使它与时间值一起工作?

But they work only with floats and integers. My question is how can i make it work with time values ?

推荐答案

基本上你可以用数字类型来表示时间！使用整数，您可以将时间范围从 0 到 Integer.MAX_VALUE 秒(例如)

Basically you can represent time with a numeric type! With integer you can have a range time from 0 to Integer.MAX_VALUE seconds (for example)

您需要的是以 mm:ss 格式显示这个 int 值.

What do you need is display this int value in a mm:ss format.

我不知道这里的库是否已经这样做了，但是我建议在上面分叉一个并处理屏幕上显示的值.

I don't know if the libs up here already do this, however I suggest to fork one on that and work on the values displayed on screen.

另一个例子(使用millis)SO链接

Example from another (using millis) SO link

String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millis),
    TimeUnit.MILLISECONDS.toMinutes(millis) % TimeUnit.HOURS.toMinutes(1),
    TimeUnit.MILLISECONDS.toSeconds(millis) % TimeUnit.MINUTES.toSeconds(1));
