android调用第三方软件打开下载的附件
在做我们产品的时候，需要下载附件， 同时下载附件需要打开， 通过查阅一些资料发现，android对这支持做的非常好，通过anction ，加minitype ，加数据源，就能找到合适的软件进行打开你的下载的附件，下面是我整理的一个的java类，希望对你有帮助！/* * @project C6Client * @package com.jh.c6.util * @file CallOtherOpeanFile.java * @version 1.0 * @author liaoyp * @time 2012-5-19 上午6:30:54 * */package com.jh.c6.util;import java.io.File;import android.content.ActivityNotFoundException;import android.content.Context;import android.content.Intent;import android.net.Uri;import android.widget.Toast;public class CallOtherOpeanFile {/** * * openFile * @description: TODO(打开附件) * @param context * @param file * @since 2012-5-19 liaoyp */public void openFile(Context context,File file){ try{ 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 context.startActivity(intent); // Intent.createChooser(intent, "请选择对应的软件打开该附件！"); }catch (ActivityNotFoundException e) {// TODO: handle exception Toast.makeText(context, "sorry附件不能打开，请下载相关软件！", 500).show();}} 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 if(end.equals(MIME_MapTable[i][0])) type = MIME_MapTable[i][1]; } return type; } // 可以自己随意添加 private 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"}, {".bmp", "image/bmp"}, {".c", "text/plain"}, {".class", "application/octet-stream"}, {".conf", "text/plain"}, {".cpp", "text/plain"}, {".doc", "application/msword"}, {".docx", "application/vnd.openxmlformats-officedocument.wordprocessingml.document"}, {".xls", "application/vnd.ms-excel"}, {".xlsx", "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"}, {".exe", "application/octet-stream"}, {".gif", "image/gif"}, {".gtar", "application/x-gtar"}, {".gz", "application/x-gzip"}, {".h", "text/plain"}, {".htm", "text/html"}, {".html", "text/html"}, {".jar", "application/java-archive"}, {".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"}, {"", "*/*"} }; }来源：http://blog.csdn.net/liao3841054/article/details/7582982
