android获取音频、视频、图片信息

MediaStore提供了音频、视频、图片信息，我们可以通过ContentResolver进行读取。

首先给出了Audio,Video和Image三个类，然后分别定义了三个Provider:AudioProvider,

VideoProvider,ImageProvider，貌似用到了工厂方法模式:D，最后给出了一个示例类Provider。

View Code
package com.provider;public class Audio {   

private int id;   

private String title;   

private String album;   

private String artist;   

private String path;   

private String displayName;   

private String mimeType;   

private long duration;   

private long size;       

/**     *      */    public Audio() {       

super();   

 }   

 /**

public Audio(int id, String title, String album, String artist,            String path, String displayName, String mimeType, long duration,            long size) {       

 super();       

 this.id = id;

public int getId() {
