在项目中,有时候遇到要求,点击播放下一曲无法播放的问题。明明调用了start()方法了,为什么还是不行呢。
以下是我的代码
mediaPlayer=new MediaPlayer(); mediaPlayer.setDataSource(url[0]); mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); mediaPlayer.prepareAsync(); mediaPlayer.start();
相信大家都懂这段代码了吧,mediaPlayer.prepareAsync();是为了异步加载网络数据,如果不这样可能app直接卡死掉。如果上面有报错记得try、catch。
后面想到了异步,那么可能是不及时的,比如说mediaPlayer.prepareAsync();刚开始是没任何东西的,可能需要延迟个几秒或毫秒才会得以加载网络的数据。那这个时候再执行mediaPlayer.start();肯定是没有播放的。后面想到了休眠,没错就是这么简单,将代码改成了
mediaPlayer=new MediaPlayer(); mediaPlayer.setDataSource(url[0]); mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); mediaPlayer.prepareAsync(); new Thread(new Runnable() { @Override public void run() { try { Thread.sleep(2000); mediaPlayer.start(); }catch (Exception e){} } }).start();
问题得以解决。
贴上全部代码,app界面如图:
