android 打开各种文件（setDataAndType）

android 打开各种文件 setDataAndType action动作

转自：http://luhuajcdd.iteye.com/blog/1560225

和http://www.2cto.com/kf/201201/117389.html

Java代码 /**
* 打开文件
* @param file
*/
private void openFile(File file){

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); //这里最好try一下，有可能会报错。 //比如说你的MIME类型是打开邮箱，但是你手机里面没装邮箱客户端，就会报错。

}

/**
* 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++){ //MIME_MapTable??在这里你一定有疑问，这个MIME_MapTable是什么？
if(end.equals(MIME_MapTable[i][0]))
type = MIME_MapTable[i][1];
}
return type;
}







MIME_MapTable是所有文件的后缀名所对应的MIME类型的一个String数组：

Java代码 <span style="white-space: pre;"> </span>private final String[][] MIME_MapTable={
//{后缀名，MIME类型}
{".3gp", "video/3gpp"},
{".apk", "application/vnd.android.package-archive"},
{".asf", "video/x-ms-asf"},
{".avi", "video/x-msvideo"},
{".bin", "application/octet-stream"},

{".java", "text/plain"},
{".jpeg", "image/jpeg"},
{".jpg", "image/jpeg"},
{".js", "application/x-javascript"},
{".log", "text/plain"},
{".m3u", "audio/x-mpegurl"},
{".m4a", "audio/mp4a-latm"},
{".m4b", "audio/mp4a-latm"},
{".m4p", "audio/mp4a-latm"},
{".m4u", "video/vnd.mpegurl"},
{".m4v", "video/x-m4v"},
{".mov", "video/quicktime"},
{".mp2", "audio/x-mpeg"},
{".mp3", "audio/x-mpeg"},
{".mp4", "video/mp4"},
{".mpc", "application/vnd.mpohun.certificate"},
{".mpe", "video/mpeg"},
{".mpeg", "video/mpeg"},
{".mpg", "video/mpeg"},
{".mpg4", "video/mp4"},
{".mpga", "audio/mpeg"},
{".msg", "application/vnd.ms-outlook"},
{".ogg", "audio/ogg"},
{".pdf", "application/pdf"},
{".png", "image/png"},
{".pps", "application/vnd.ms-powerpoint"},
{".ppt", "application/vnd.ms-powerpoint"},
{".pptx", "application/vnd.openxmlformats-officedocument.presentationml.presentation"},
{".prop", "text/plain"},
{".rc", "text/plain"},
{".rmvb", "audio/x-pn-realaudio"},
{".rtf", "application/rtf"},
{".sh", "text/plain"},
{".tar", "application/x-tar"},
{".tgz", "application/x-compressed"},
{".txt", "text/plain"},
{".wav", "audio/x-wav"},
{".wma", "audio/x-ms-wma"},
{".wmv", "audio/x-ms-wmv"},
{".wps", "application/vnd.ms-works"},
{".xml", "text/plain"},
{".z", "application/x-compress"},
{".zip", "application/x-zip-compressed"},
{"", "*/*"}
};

这个MIME类型可能不够完整，你有要补充的吗？
