一、实现效果
废话不多说，直接上代码，里面有详细注释，不清楚的评论区留言。
二、布局代码
<?xml version="1.0" encoding="utf-8"?>

<SeekBar

</LinearLayout>
</RelativeLayout>
三、Activity代码

import android.widget.ImageButton;

import android.widget.TextView;
import android.widget.VideoView;
import com.example.tabtest.R;
import com.example.tabtest.util.FormatTime;

/**

自定义一个进度条时间转换工具类，超简单
public class FormatTime {
public String SecondToTime(int seconds){
int second = seconds % 60;
int m = seconds / 60;
int h = seconds /60 /60;
return h+":"+m+":"+second;
}
}
