android 打开各种文件（setDataAndType）

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); //    public Intent setDataAndType(Uri data, String 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; 
}
