AsyncPlayer

版本：Android 3.0 r1

结构

继承关系

public classAsyncPlayerextendsObject

java.lang.Object

android.media.AsyncPlayer

类概述

播放一个连续(多个)的音频URLs，但那些任务较重的工作在另外的线程中完成，所以任何预处理或加载的延迟都不阻碍线程调用。

构造函数

publicAsyncPlayer(String tag)

构造一个AsyncPlayer对象。

参数

tag用于调试的字符串

公共方法

public voidplay(Context context, Uri uri, boolean looping, int stream)

开始播放声音。可在某个点上开始播放。这里不保证可能有延迟。在另一个音频文件播放时调用这个方法将导致当前音频停止播放并开始播放新的音频。

参数

context应用程序上下文

uri播放的URI (参见setDataSource(Context, Uri))

looping是否无限循环播放声音。(参见setLooping(boolean))

stream音频流(AudioStream)类型(参见setAudioStreamType(int))（译者注：例如AudioManager.STREAM_MUSIC）

public voidstop()

停止之前播放的声音。不能在某点上暂停然后接着播放。多次调用没有不良影响。
