安卓媒体播放器

我正在尝试使用 MediaPlayer 对象播放声音，但尽管我尽了最大努力，但似乎无法让它工作。声音只是拒绝播放。

这是一个短的声音，应该在触摸屏幕时播放，这意味着它必须重复很多次，而不会造成太多延迟。知道这一点后，我遵循了状态图， http://developer.android.com/reference /android/media/MediaPlayer.html。我似乎看不出我的方法调用顺序到底出了什么问题。

MediaPlayer mp = MediaPlayer.create(this.getContext(), R.raw.select2);
try {
    mp.prepare();
    mp.start();                 
    Log.e("debug","sound played");
    }
catch(Exception e) {}
mp.stop();

I am attempting to play a sound using a MediaPlayer object, but I cannot seem to get it to work despite my best efforts. The sound simply refuses to play.

It's a short sound, that is supposed to be played when the screen is touched, meaning it will have to be repeated many times without too much delay. Knowing this I followed the state diagram, http://developer.android.com/reference/android/media/MediaPlayer.html. I can't seem to see what exactly is wrong with my sequencing of method calls.

MediaPlayer mp = MediaPlayer.create(this.getContext(), R.raw.select2);
try {
    mp.prepare();
    mp.start();                 
    Log.e("debug","sound played");
    }
catch(Exception e) {}
mp.stop();

您在媒体播放器上调用 prepare() ，但是 create() 您使用的调用会自动准备播放器，当您尝试调用 prepare()< 时，这会导致 IllegalStateException /代码>再次，您将被发送到您的catch()（如果您以某种方式处理异常，即打印堆栈跟踪，您会注意到这一点）。

MediaPlayer player = MediaPlayer.create(this.getContext(), R.raw.select2);

我们通过设置音乐播放器的一些属性来配置音乐播放器，如下所示

player.setWakeMode(getApplicationContext()PowerManager.PARTIAL_WAKE_LOCK);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnPreparedListener(this);
player.setOnCompletionListener(this);
player.setOnErrorListener(this);
try {
   player.prepare();
   player.start();                 
   Log.e("debug","sound played");
}  catch(Exception e) {}
  player.stop();

MediaPlayer player = MediaPlayer.create(this.getContext(), R.raw.select2);

we configure the music player by setting some of its properties as shown below

player.setWakeMode(getApplicationContext()PowerManager.PARTIAL_WAKE_LOCK);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnPreparedListener(this);
player.setOnCompletionListener(this);
player.setOnErrorListener(this);
try {
   player.prepare();
   player.start();                 
   Log.e("debug","sound played");
}  catch(Exception e) {}
  player.stop();
