就这样让一个类的共享preference

do like this make one class for your sharedpreference

public class Session {

    private SharedPreferences prefs;

    public Session(Context cntx) {
        // TODO Auto-generated constructor stub
        prefs = PreferenceManager.getDefaultSharedPreferences(cntx);
    }

    public void setusename(String usename) {
        prefs.edit().putString("usename", usename).commit();
        prefsCommit();
    }

    public String getusename() {
        String usename = prefs.getString("usename","");
        return usename;
    }
}

现在做这个类当U想用这种使用这样的化妆对象OG这个类像

now after making this class when u want to use this use like this make object og this class like

private Session session;//global variable 
session = new Session(cntx); //in oncreate 
//and now we set sharedpreference then use this like

session.setusename("USERNAME");

现在当过ü要获得用户名，然后对会话对象相同的工作，并把这种

now when ever u want to get username then same work for session object and call this

session.getusename();
