选择软件打开文件，主要是判断文件的类型，然后设置intent的action（Intent.ACTION_VIEW），以及 intent.setDataAndType(）去选择软件打开文件
package com.gainet.mb.utils;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 {/**      *       * <code>openFile</code>      * @description: TODO(打开附件)       * @param context      * @param file      * @since        */      public static 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 static 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];
