判断用户名只支持中英文和下划线

public static boolean checkLetterInvalid(String s)

{

char[] cs = s.toCharArray();

boolean flag = true;

for(char c:cs)

{

if(Character.isDigit(c))

{

continue;

}

if(Character.isLetter(c))

{

continue;

}

if(c == 95)

{

continue;

}

Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);

if(ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS)

{

continue;

}

flag = false;

break;

}

return flag;

}

[2] MediaPlayer中的几种播发音乐文件的方式(转）

来源: 互联网发布时间: 2014-02-18

MediaPlayer中的几种播放音乐文件的方式(转）

在MediaPlayer中的几种播放音乐文件的方式

1. 有下载的好的资源

a) 直接实例化MediaPlayer，把音乐文件加载进去就可以播放

b) 调用mediaplayer中的Create的方法。有两个参数(作用类，和音乐文件路径)

代码如下

// 给mediaPlayer对象实例化

mdplay = new MediaPlayer()；

// 指定相应播放对象

// mdplay = MediaPlayer.create(Player.this, R.raw.shi);

2. 直接加载Uri地址，没有下载资源

a) 首先定义Uri的对象，并赋予uri地址

b) 也是调用mediaplayer中Create的方法。传入两个参数（作用类，和uri对象）

代码如下：

// 创建Uri的对象

Uri u = Uri.parse("http://www.166china.com/zhuanti/aa.mp3");

mdplay = MediaPlayer.create(Player.this, u);

3. 直接调用mediaplayer的构造函数

a) 首先定义一个String类型的变量，接收uri的地址

b) 在调用构造函数中setDataSource的方法

代码如下：

mdplay=new MediaPlayer();

String path="http://www.166china.com/zhuanti/aa.mp3";
