所以我们可以通过下面的语句获得: AudioManager audiomanage = (AudioManager)getAcitivity().getSystemService(Context.AUDIO_SERVICE...); audiomanager就是我们定义的控制系统声音的对象。...,AudioManager.ADJUST_LOWER, AudioManager.FX_FOCUS_NAVIGATION_UP); } //增加音量..., AudioManager.FX_FOCUS_NAVIGATION_UP); } 常用方法： android audioManager获取音量...： 先获取AudioManager实例， AudioManager mAudioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE

框架文档地址：GameAIs.Com LollipopCreator:AudioManager LollipopCreator游戏框架 游戏客户端开发中，由于制作人或者策划立项的不同，导致前端开发并不像后端框架不变...return -1 } 注意点：主资源位置Master/data/sound 子游戏资源位置SubModules/${moduleName}/data/sound 实例代码 class AudioManager...this.model.musicFile = null this.model.musicID = -1 } } } window.audioMgr = new AudioManager
应用还必须为这两个调用注册 AudioManager.OnAudioFocusChangeListener，以便接收回调并管理自己的音量。...API介绍 处理音频焦点都是通过AudioManager这个类，如下是获得该类实例的方法： AudioManager am = (AudioManager) mContext.getSystemService...abandonAudioFocus(OnAudioFocusChangeListener l) 参数通上 AudioManager.OnAudioFocusChangeListener ....; case AudioManager.AUDIOFOCUS_LOSS: // TBD 停止播放 break; case AudioManager.AUDIOFOCUS_LOSS_TRANSIENT...AudioManager mAudioManager; private AudioFocusRequest mFocusRequest; private AudioManager.OnAudioFocusChangeListener
AudioManager.ADJUST_RAISE : AudioManager.ADJUST_LOWER; int flags = AudioManager.FX_FOCUS_NAVIGATION_UP...audioManager.setStreamVolume(AudioManager.STREAM_SYSTEM, audioManager.getStreamVolume...(AudioManager.STREAM_SYSTEM), AudioManager.FX_KEY_CLICK); } else { audioManager.setSpeakerphoneOn...), AudioManager.FX_KEY_CLICK); } else { audioManager.setMode(AudioManager.MODE_IN_CALL...(AudioManager.STREAM_VOICE_CALL), AudioManager.FX_KEY_CLICK); } } } audioManager.setMode(
audioManager; audioManager = ((AudioManager) getSystemService(AUDIO_SERVICE)); 3.设置几个属性 private...(AudioManager.ROUTE_SPEAKER); // 获取当前通话音量 currVolume = audioManager.getStreamVolume...audioManager.setStreamVolume(AudioManager.STREAM_VOICE_CALL, audioManager.getStreamMaxVolume...(AudioManager.STREAM_VOICE_CALL), AudioManager.STREAM_VOICE_CALL);...(false); audioManager.setStreamVolume(AudioManager.STREAM_VOICE_CALL, currVolume,
audioSource.PlayOneShot(jumpClip, 10f); } 声音管理类: 单例模式(Mono中与C#中的单例有区别) AudioSource audioSource; //单例保证AudioManager...的唯一性 private static AudioManager instance; public static AudioManager Instance {...instance == null) { //在找的时候构造出来一个Object GameObject go = new GameObject("audioManager..."); go.AddComponent(); } return instance;...} } //禁止外接通过new的方式获取该类 private AudioManager() { } private void Awake() {

android的消息提示（震动和提示音），实现代码如下所示： public class VibratorUtil { protected AudioManager audioManager;...static final int MIN_TIME_OUT = 4000; //时间间隔 long lastNotificationTime; public VibratorUtil() { audioManager...= (AudioManager) MyApp.getContext().getSystemService(Context.AUDIO_SERVICE); //此方法是由Context调用的 vibrator...{ return; } try { lastNotificationTime = System.currentTimeMillis(); if (audioManager.getRingerMode...() == AudioManager.RINGER_MODE_SILENT) { return; } long[] pattern = new long[]{0,

AudioManager对象才可以使用. eg : AudioManager audioManager = (AudioManager)getApplicationContext().getSystemService...(Context.AUDIO_SERVICE); 利用AudioManager获取当前音量的方法 : float currVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC...); 利用AudioManager获取当前系统最大音量方法 : float maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC...audioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE); float currVolume = audioManager.getStreamVolume...(AudioManager.STREAM_MUSIC); float maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC
例如我们要获取AudioManager，我们可以： AudioManager am = (AudioManager) getSystemService(Context.AUDIO_SERVICE); 获取的服务...可以看ContextImpl.java中的实现: static { ...... // 将AudioManager加入SYSTEM_SERVICE_MAP中，调用getSystemService...时， // 就会从SYSTEM_SERVICE_MAP得到AudioManager registerService(AUDIO_SERVICE, new ServiceFetcher()...}}); ...... } AudioManager是对IAudioService的封装，实际操作都是使用IAudioService进行的，看AudioManager中的代码： private...现在，我们就可以使用AudioManager中的isStreamMute(int streamType)方法了 ?
（在 builder 中必须指明请求的音频焦点类型） AudioManager mAudioManager = (AudioManager) mContext.getSystemService(Context.AUDIO_SERVICE...: // 不允许播放 case AudioManager.AUDIOFOCUS_REQUEST_GRANTED: // 开始播放 } 音频焦点类型要点: AudioManager.AUDIOFOCUS_GAIN...调用 AudioManager 的 requestAudioFocus(…) 方法，需要用到实例化好的 AudioFocusRequest。...代码如下： AudioManager mAudioManager = (AudioManager) mContext.getSystemService(Context.AUDIO_SERVICE); int..., AudioManager.AUDIOFOCUS_GAIN); switch (focusRequest) { case AudioManager.AUDIOFOCUS_REQUEST_FAILED
audioManager; private AudioManager.OnAudioFocusChangeListener listener; @Override protected void onResume...() { if (audioManager!...= null) { audioManager.abandonAudioFocus(listener); audioManager = null; } super.onResume...(); } @Override protected void onPause() { audioManager = (AudioManager) mContext.getSystemService...(listener, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN_TRANSIENT); if (result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED
; private String mCurrentFilePath; private static AudioManager mInstance; private boolean isPrepared;...private AudioManager(String dir) { this.mDir = dir; } //单例模式：在这里实例化AudioManager并传入录音文件地址 public static...AudioManager getInstance(String dir) { if (mInstance == null) { synchronized (AudioManager.class) {...mAudioManager; private android.media.AudioManager audioManager; public AudioRecorderButton(Context context...() { audioManager.requestAudioFocus(onAudioFocusChangeListener, android.media.AudioManager.STREAM_MUSIC
我一看 API，是挺简单的： private void setMuteEnabled(boolean enabled){ AudioManager mAudioManager = (AudioManager...正当我收起我惊呆了的下巴的时候，我回过神来，准备对 AudioManager 的身世一探究竟。且说，AudioManager 是怎么来的？...它在这里 new 了一个 AudioManager。它怎么能new 了一个 AudioManager 呢。...按照我们刚才的推断，前后两次操作 AudioManager 是不一样的，而同一个 Context 返回的 AudioManager 只能是一个实例，换句话说，只要我们每次获取 AudioManager...6、『这事儿还是交给同一个人办比较靠谱』 有了前面的分析，解决方法其实也就浮水而出了： AudioManager mAudioManager = (AudioManager) getContext().
