需要使用到的Animation资源

fade_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"android:duration="200"><alphaandroid:fromAlpha="0"android:toAlpha="1" />
</set>

fade_in.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"android:duration="1500" android:startOffset="2000"><alphaandroid:fromAlpha="1"android:toAlpha="0" />
</set>

slide_down.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"android:duration="500" android:startOffset="2000"><translateandroid:fromYDelta="0%"android:toYDelta="100%" />

<set xmlns:android="http://schemas.android.com/apk/res/android"android:duration="200"><translateandroid:fromYDelta="100%"android:toYDelta="0%" />

需要自定义的工具类

FormatTimeUtil

package zhonghui.he.video.utils;import java.text.DecimalFormat;public class FormatTimeUtil {private static DecimalFormat decimalFormat = new DecimalFormat("00");public static String format(long milliseconds) {milliseconds = milliseconds / 1000;int second = (int) milliseconds % 60;int mirror = (int) milliseconds / 60 % 60;int hour = (int) milliseconds / 60 / 60 % 60;StringBuffer stringBuffer = new StringBuffer();return stringBuffer.append(decimalFormat.format(hour)).append(":").append(decimalFormat.format(mirror)).append(":").append(decimalFormat.format(second)).toString();}}
