阅读更多关于 Android: Mediaplayer stop / start playing raw resource

问题 It now plays on first press, stops on second press or press of another sound button. If I let a sound play through I can restart it or play another sound on a single press.

MediaPlayer vs SoundPool for only 1 simultaneous stream

阅读更多关于 MediaPlayer vs SoundPool for only 1 simultaneous stream

问题 I'm working on a game in which one single sound is played each time the phone is shaked. Does it make sense to use a SoundPool and load sounds in the onCreate of my activity, or is it ok to create a mediaplayer each time, as shown below: private void onShake() { MediaPlayer mp= MediaPlayer.create(this, whipSound[currentWhip][force]); mp.start(); } My guess is that SoundPool is better because the sounds are loaded only once. Am I right? Thanks Julien 回答1: As expected, SoundPool is much faster.
