Vitamio簡(jiǎn)介：Vitamio是一個(gè)支持所有Android設(shè)備的多媒體框架。Vitamio與Android默認(rèn)的MediaPlayer工作方式相似，但包含更加強(qiáng)大的功能！（注意：Vitamio商業(yè)化后個(gè)人免費(fèi)、公司收費(fèi)）

之前開(kāi)發(fā)一個(gè)視頻播放類(lèi)的項(xiàng)目，需要實(shí)現(xiàn)在線播放的功能，找了很多視頻播放框架，覺(jué)得Vitamio視頻播放框架還不錯(cuò)，也相對(duì)穩(wěn)定，但是在網(wǎng)上找了很多教程都少之又少，Vitamio官網(wǎng)寫(xiě)的教程也不是很清晰，所以就自己就把Vitamio在github上的demo進(jìn)行研究，花了點(diǎn)時(shí)間寫(xiě)了個(gè)demo出來(lái)并且將Vitamio的視頻控制器界面進(jìn)行自定義，支持視頻亮度、音量的調(diào)節(jié)，話不多說(shuō)，先上效果圖。

自定義視頻控制器

目前，作者只實(shí)現(xiàn)了自定義手勢(shì)調(diào)節(jié)亮度、音量的加減以及播放控制的功能，更多的功能等待著大家一起去挖掘。

使用步驟

1、引入vitamio SDK的方式有兩種：

• 直接以module的方式引入
• 通過(guò)Complie的方式引入

作者是采用的第一種方式，下面是一些需要注意的地方：

清單文件配置，權(quán)限設(shè)置：

<uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

application配置：

<!-- 必須初始化 --> <activity android:name="io.vov.vitamio.activity.InitActivity" android:configChanges="orientation|screenSize|smallestScreenSize|keyboard|keyboardHidden|navigation" android:launchMode="singleTop" android:theme="@android:style/Theme.NoTitleBar" android:windowSoftInputMode="stateAlwaysHidden" />
