[amy_liang]

public void playFromNet(View view){
String path = "http://www.kuwo.cn/yinyue/3638735?catalog=yueku2016";//音乐地址
MediaPlayer mediaPlayer = new MediaPlayer();
try {
mediaPlayer.setDataSource(this,Uri.parse(path));

Toast.makeText(MainActivity.this,"缓冲",Toast.LENGTH_SHORT).show();
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
Toast.makeText(MainActivity.this,"缓冲mp "+mp,Toast.LENGTH_SHORT).show();
mp.start();
}
});
mediaPlayer.prepareAsync(); //异步缓冲.使用另外一个线程缓冲，在界面看起来不卡顿

} catch (IOException e) {
e.printStackTrace();
}
