android surfaceView+mediaPlayer 自定義視訊播放器
阿新 • • 發佈：2019-01-26
Android 視訊播放一般分為兩種（其實3種，還一種是調Android自帶播放器）：
1.使用Android自帶View VideoView ,其中一些功能，已經都給實現好了(此view一般不滿足自己的需求，比如：介面啊，控制啊，以及可能還有手勢控制音量，手勢控制亮度等等，那麼就會選擇第二種方式)
2.surfaceView+mediaPlayer 自定義播放器（這個可以製作自己想要任何功能以及介面的播放器，當然前提得自己實現）
主要就是
surfaceView：介面輸出
mediaPlayer ：媒體控制 ：包括音量，暫停，播放，停止等等，還有視訊各種狀態的監聽等等。
本片博文不對surfaceView和mediaPlayer 這兩個類細解，如果你不瞭解這兩個類的話，看本博文之前應該先去好好了解一下，不然很難看懂，在這裡就不說了，直接看效果。
