Android 判断文件类型MIME

MIME:全称Multipurpose Internet Mail Extensions,多功能Internet 邮件扩充服务。它是一种多用途网际邮件扩充协议,在1992年最早应用于电子邮件系统,但后来也应用到浏览器。MIME类型就是设定某种扩展名的文件用一种应用程序来打开的方式类型,当该扩展名文件被访问的时候,浏览器会自动使用指定应用程序来打开。多用于指定一些客户端自定义的文件名,以及一些媒体文件打开方式。

在Android中通过文件的MIME类型来判断有哪些应用程序可以处理这些文件,并使用其中的某一个应用程序(如果有多个可选的应用程序,则用户必须指定一个)处理之。

我在写android资源管理器(文件浏览器)的时候,希望能在资源管理器的中实现打开文件的操作,此时就需要用到文件的MIME类型。

一:获取本地文件类型:

/**
 * 根据文件后缀名获得对应的MIME类型。
 * @param file
 */
private String getMIMEType(File file)
{
    String type="*/*";
    String fName=file.getName();
    //获取后缀名前的分隔符"."在fName中的位置。
    int dotIndex = fName.lastIndexOf(".");
    if(dotIndex < 0){
        return type;
    }
    /* 获取文件的后缀名 */
    String end=fName.substring(dotIndex,fName.length()).toLowerCase();
    if(end=="")return type;
    //在MIME和文件类型的匹配表中找到对应的MIME类型。
    for(int i=0;i<MIME_MapTable.length;i++){
        if(end.equals(MIME_MapTable[i][0]))
            type = MIME_MapTable[i][1];
    }
    return type;
}
/**
 * 打开文件
 * @param file
 */
private void openFile(File file){
    //Uri uri = Uri.parse("file://"+file.getAbsolutePath());
    Intent intent = new Intent();
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    //设置intent的Action属性
    intent.setAction(Intent.ACTION_VIEW);
    //获取文件file的MIME类型
    String type = getMIMEType(file);
    //设置intent的data和Type属性。
    intent.setDataAndType(/*uri*/Uri.fromFile(file), type);
    //跳转
    startActivity(intent);    
}

二:获取URL文件类型:

 

 

详细信息mime类型可以参照w3c网址介绍:http://www.w3school.com.cn/media/media_mimeref.asp

其实,这些格式管理员都可以自己添加的,系统会自动生成MIME头,当然可能会有一些稀少的文件格式,还需要检测后才能获得它们的MIME格式,一般通用的系统都可以自动生成。

支持java下载:在iis中需要添加
.jad text/vnd.sun.j2me.app-descriptor
.jar application/java-archive

支持sis文件下载:在iis中需要添加
.sis application/vnd.symbian.install

另外你还可以这样设:
