Android 通过工具类查询MIME打开各种文件的方法
来源：互联网 发布：中青宝网络 编辑：程序博客网 时间：2024/05/16 12:26
Android开发中，总会遇到打开查看某些文件的需求，有时候需要要求内部打开，也有时候为了省事，使用手机已安装的第三方软件来进行查看，我也遇到了这样的情况，把网上找的方法记录一下：
个人感觉最靠谱的方法就是创建一个用来处理文件后缀，以获取相应MIME类型，然后使用该MIME寻找可以打开的软件。
具体步骤嘛，新建个MimeTypeUtil（名字随便起）类，然后把下面的代码粘贴进去就好了，需要的时候直接调用里面的静态方法就好了：
在粘贴MIME代码之前还是粘贴一段使用的代码吧：
//假设这个filePath是完整的路劲String filePath = "/xxxx/ceshi/xxx.pdf";Uri uri = Uri.parse("file://" +filePath);Intent intent = new Intent();intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);intent.setAction(Intent.ACTION_VIEW);//获取对应的MIMEString type = MimeTypeUtil.getMIMEType(filePath);intent.setDataAndType(uri, type);startActivity(intent);
MimeTypeUtil类“
package com.example.datademo.util;/** * Created by Administrator on 2015/12/9. */public class MimeTypeUtil { /** * 获取文件类型 */ public static String getMIMEType(String filePath) { String type = "*/*"; String fName = filePath; int dotIndex = fName.lastIndexOf("."); if (dotIndex < 0) { return type; } String end = fName.substring(dotIndex, fName.length()).toLowerCase(); if (end == "") { return type; } for (int i = 0; i < MIME_MapTable.length; i++) { if (end.equals(MIME_MapTable[i][0])) { type = MIME_MapTable[i][1]; } } return type; } /** * MIME 列表 */ public static final String[][] MIME_MapTable = { // {后缀名， MIME类型} { ".3gp", "video/3gpp" }, { ".3gpp", "video/3gpp" }, { ".aac", "audio/x-mpeg" }, { ".amr", "audio/x-mpeg" }, { ".apk", "application/vnd.android.package-archive" }, { ".avi",
