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={

 这个MIME类型可能不够完整,你有要补充的吗?
