本文實(shí)例為大家分享了VideoView原生自定義視頻播放器的具體代碼，供大家參考，具體內(nèi)容如下
項(xiàng)目用到的技術(shù)點(diǎn)和亮點(diǎn)
- VideoView封裝視頻播放工具類
- 自定義視頻控制面板
- 手勢(shì)識(shí)別器的使用
1. VideoView封裝視頻播放工具類
視頻播放這些其實(shí)都挺簡(jiǎn)單的，VideoView這個(gè)類都提供了相應(yīng)方法，詳細(xì)見代碼 代碼都比較簡(jiǎn)單，不過需要注意的是要在主線程中更新視頻面板的UI信息。

3. 自定義視頻控制面板
代碼比較簡(jiǎn)單同時(shí)代碼不長(zhǎng) 都有注釋 需要的可以參考下 大神勿噴
