您应该使用音频焦点为此。参考RandomMusicPlayer示例android项目：
public class AudioFocusHelper {
AudioManager mAM;
MusicFocusable mFocusable;
private final AudioManager.OnAudioFocusChangeListener listener = new AudioManager.OnAudioFocusChangeListener() {
@Override
/**
* Called by AudioManager on audio focus changes. We implement this by calling our
* MusicFocusable appropriately to relay the message.
*/
public void onAudioFocusChange(int focusChange) {
if (mFocusable == null) return;
switch (focusChange) {
case AudioManager.AUDIOFOCUS_GAIN:
mFocusable.onGainedAudioFocus();
break;
case AudioManager.AUDIOFOCUS_LOSS:
case AudioManager.AUDIOFOCUS_LOSS_TRANSIENT:
mFocusable.onLostAudioFocus(false);
break;
case AudioManager.AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK:
mFocusable.onLostAudioFocus(true);
break;
default:
}
}
};;
public AudioFocusHelper(Context ctx, MusicFocusable focusable) {
mAM = (AudioManager) ctx.getSystemService(Context.AUDIO_SERVICE);
mFocusable = focusable;
}
/** Requests audio focus. Returns whether request was successful or not. */
public boolean requestFocus() {
return AudioManager.AUDIOFOCUS_REQUEST_GRANTED ==
mAM.requestAudioFocus(listener, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);
}
/** Abandons audio focus. Returns whether request was successful or not. */
public boolean abandonFocus() {
return AudioManager.AUDIOFOCUS_REQUEST_GRANTED == mAM.abandonAudioFocus(listener);
}
}
