Spinner
作为下拉选项列表 还是非常不错 且易用的 同时 也存在一些局限性 比如： 标题栏 下拉栏 显示内容必须一致 这使得其
实用性大打折扣
1. 先说说其不足之处 即： 标题 下拉 显示内容 相同问题：
* 定义待显示内容 以TextView为例：
String[] content = {
"eoe.android","eoe.mobile","eoe.mark","eoe.rd","eoe.mobile"
};
* 定义 CustomAdapter :
public class CustomAdapter extends BaseAdapter {
Activity activity;
public CustomAdapter(Activity a){
activity = a;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return content.length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
TextView tv = new TextView(activity);
tv.setText(content[position]);
tv.setTextSize(20);
return tv;
}
}
* emulator 运行效果 可以看出 标题 下拉 显示内容 是一样的
2. 使得 标题 下拉 二者显示内容不同
* 定义标题显示内容:title 下拉继续使用上面定义的content
String[] title = {
"0","1","2","3","4","5"
};
* 定义 CustomSpinnerAdapter:
public class CustomSpinnerAdapter implements SpinnerAdapter {
Activity activity;
public CustomSpinnerAdapter(Activity a){
activity = a;
}
@Override
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
// TODO Auto-generated method stub
TextView tv = new TextView(activity);
tv.setText(content[position]);
tv.setTextSize(20);
tv.setTextColor(Color.RED);
return tv;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return content.length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public int getItemViewType(int position) {
// TODO Auto-generated method stub
return IGNORE_ITEM_VIEW_TYPE;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
TextView tv = new TextView(activity);
tv.setText(title[position]);
tv.setTextColor(Color.GREEN);
return tv;
}
@Override
public int getViewTypeCount() {
// TODO Auto-generated method stub
return content.length;
}
@Override
public boolean hasStableIds() {
// TODO Auto-generated method stub
return false;
}
@Override
public boolean isEmpty() {
// TODO Auto-generated method stub
return false;
}
@Override
public void registerDataSetObserver(DataSetObserver observer) {
// TODO Auto-generated method stub
}
@Override
public void unregisterDataSetObserver(DataSetObserver observer) {
// TODO Auto-generated method stub
}
}

ubuntu samba配置
关键字: ubuntu samba
转自：
http://www.5ilinux.com/samba.html
一、samba要求：
公司有财务，技术，领导3个部门，我们分别为3个部门建立3个用户组为caiwu,network,lingdao;
三个部门里各有2个用户，我们建用户分别为caiwu01,caiwu02,network01,network02,lingdao01,lingdao02
然后我们分别就公司的具体情况建立相应的目录及访问权限，通过以下的例子，希望大家能在平时的工作中灵活的应用samba的安全权限来设置你们的samba文件服务器。
1。首先服务器采用用户验证的方式，每个用户可以访问自己的宿主目录，并且只有该用户能访问宿主目录，并具有完全的权限，而其他人不能看到你的宿主目录。
2。建立一个caiwu的文件夹，希望caiwu组和lingdao组的人能看到，network02也可以访问，但只有caiwu01有写的权限。
3。建立一个lindao的目录，只有领导组的人可以访问并读写，还有network02也可以访问，但外人看不到那个目录
4。建议一个文件交换目录exchange，所有人都能读写，包括guest用户，但每个人不能删除别人的文件。
5。建议一个公共的只读文件夹public，所有人只读这个文件夹的内容。
二、操作
#groupadd caiwu
#groupadd network
#groupadd lingdao
#useradd caiwu01 -g caiwu
#useradd caiwu02 -g caiwu
#useradd network01 -g network
#useradd network02 -g network
#useradd lingdao01 -g lingdao
#useradd lingdao02 -g lingdao
然后我们使用smbpasswd -a caiwu01的命令为6个帐户分别添加到samba用户中
#mkdir /home/samba
#mkdir /home/samba/caiwu
#mkdir /home/samba/lingdao
#mkdir /home/samba/exchange
#mkdir /home/samba/public
我们为了避免麻烦可以在这里把上面所有的文件夹的权限都设置成777，我们通过samba灵活的权限管理来设置上面的5点要求。
三、vim /etc/samba/smb.conf
[global]
workgroup = Ubuntu
server string = Ubuntu Samba Test
security = user
encrypt passwords = true
smb passwd file = /etc/samba/smbpasswd
[homes]
comment = Home Directories
browseable = no
writable = yes
valid users = %S
create mode = 0664
directory mode = 0775
#homes段满足第1条件,需要说明的是需要在/home目录里手动为每位用户建立相应的家目录，并设置好相应权限。
[caiwu]#满足我们的第2要求
comment = caiwu
path = /home/samba/caiwu
public = no
valid users = @caiwu,@lingdao,network02
write list = caiwu01
[lingdao]#满足我们的第3要求
comment = Lingdao
path = /home/samba/lingdao
public = no
valid users = @lingdao,network02
writeable = yes
[exchage]
comment = Exchange File Directory
path = /home/samba/exchange
public = yes
writable = yes
#exchange段基本能满足我们的第4要求，但不能满足每个人不能删除别人的文件这个条件，即使里设置了mask也是没用，其实这个条件只要unix设置一个粘着位就行
chmod -R 1777 /home/samba/exchange
注意这里权限是1777，类似的系统目录/tmp也具有相同的权限，这个权限能实现每个人能自由写文件，但不能删除别人的文件这个要求"有些疑问！！！"
[Public]#满足我们的第5要求。
comment = read only Public
path = /home/samba/public
public = yes
read only = yes
重启服务：#/etc/rc.d/init.d/smb restart
到此配置结束，可以使用命令：testparm /etc/samba/smb.conf检测samba配置文件
四、验证samba
在windows下直接在运行里输入：\\server
然后输入相应用户名和密码就可以访问
在linux下可以使用：
smbclient //服务器ip/caiwu -U caiwu01
#以caiwu01用户的名义登录caiwu目录
smbmount //服务器ip/caiwu /mnt/caiwu -o username=caiwu01
#把服务器的财务目录映射到本地的/mnt/caiwu目录
