XE5开发Android程序调用电话相关功能(短信息和电话) 时间：2013-9-19 16:46:08 点击：5570 　　核心提示： 其实都可以通过intent和URI调用系统功能.Windows程序员可以理解成是ShellExecute.这个是万金油.可以有调用各种功能.后面会介绍.1.短信息.很简单方法a.不使用Intent而是直接发短信.smsManager对应的Delphi代码应该是:uses Androidapi.JNI... 其实都可以通过intent和URI调用系统功能.Windows程序员可以理解成是ShellExecute.这个是万金油.可以有调用各种功能.后面会介绍. 1.短信息.很简单 方法a.不使用Intent而是直接发短信. smsManager对应的Delphi代码应该是: uses Androidapi.JNI.JavaTypes,Androidapi.JNI.Telephony; var j: JSmsManager; begin j := tjsmsmanager.Create; j.sendTextMessage(stringtojstring('137114553XX'), nil, stringtojstring('测试短信'), nil, nil); end; 至于双卡双待用哪个卡来发送这些我没有详细研究,有兴趣的朋友可以研究下.

Luogu 分析 分层最短路模板题。 话说我卡了半天发现是 insert 函数写错了？？？ 代码 #include <queue> #include <cstdio> #include <cstring> #include <iostream> #include <algorithm> #define N 100001 #define il inline #define re register #define INF 0x3f3f3f3f #define tie0 cin.tie(0),cout.tie(0) #define fastio ios::sync_with_stdio(false) #define File(x) freopen(x".in","r",stdin);freopen(x".out","w",stdout) using namespace std; typedef long long ll; template <typename T> inline void read(T &x) { T f = 1; x = 0; char c; for (c = getchar(); !isdigit(c); c = getchar()) if (c == '-') f = -1; for ( ; isdigit(c); c = getchar()) x = x * 10

用户登录、登出、登录限制 1、在app01/models.py里面定义User模型，通过AbstractBaseUser扩展用户模型 from django.db import models from django.contrib.auth.models import BaseUserManager, AbstractBaseUser, PermissionsMixin from django.contrib.auth import get_user_model class UserManager(BaseUserManager): def _create_user(self , telephone, username, password, **kwargs): if not telephone: raise ValueError("必须要传递手机号码！") if not password: raise ValueError("必须要传递密码") user = self.model( telephone = telephone, username= username , **kwargs) user.set_password( password ) user.save() return user def create_user(self, telephone, username,

传送门 Luogu 解题思路 考虑二分，每次把大于二分值的边的权设为1，小于等于的设为0，如果最短路<=k则可行，记得判无解 细节注意事项 咕咕咕 参考代码 #include <algorithm> #include <iostream> #include <cstring> #include <cstdlib> #include <cstdio> #include <cctype> #include <cmath> #include <ctime> #include <queue> #define rg register using namespace std; template < typename T > inline void read(T& s) { s = 0; int f = 0; char c = getchar(); while (!isdigit(c)) f |= (c == '-'), c = getchar(); while (isdigit(c)) s = s * 10 + (c ^ 48), c = getchar(); s = f ? -s : s; } const int _ = 1002; const int __ = 10002; int tot, head[_], nxt[__ << 1], ver[__ << 1], w[__ << 1];

1. 表关系models from django.db import models class Author(models.Model): """ 作者表 """ name = models.CharField(max_length=32) age = models.IntegerField() sex = models.CharField(max_length=20, default='male') au = models.OneToOneField("AuthorDetail",on_delete=models.CASCADE) def __str__(self): return self.name class AuthorDetail(models.Model): """ 作者详细信息表 """ birthday = models.DateField() telephone = models.CharField(max_length=11) addr = models.CharField(max_length=64) # class Meta: # db_table='authordetail' #指定表名 # ordering = ['-id',] def __str__(self): return self.telephone + self.addr class

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I'm learning Symfony 2 and I got the following error when I submit a form: Catchable Fatal Error: Argument 1 passed to Doctrine\Common\Collections\ArrayCollection::__construct() must be of the type array, object given, called in C:\xampp\htdocs\ppe2\vendor\doctrine\orm\lib\Doctrine\ORM\UnitOfWork.php on line 555 and defined Here is my code : Controller : public function ajouterAction(Request $request){ $sponsor = new Sponsor(); $formulaire = $this->createForm(new SponsorType(), $sponsor)->add('Ajouter', 'submit'); if ($formulaire-

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I am parsing HTML text with Telephone = soup.find(itemprop="telephone").get_text() In the case a Telephone number is in the HTML after the itemprop tag, I receive a number and get the output ( "Telephone Number: 34834243244" , for instance). Of course, I receive AttributeError: 'NoneType' object has no attribute 'get_text' in the case no telephone number is found. That is fine. However, in this case I would like Python not to print an error message and instead set Telephone = "-" and get the output "Telephone Number: -" . Can anybody advise

i的初始化写成2了于是成功查错2h……怕不是个傻子 设f[i][j]为第i根高为j，转移是 \[ f[i][j]=min(f[i-1][k]+abs(k-j)*c+(j-h[i])^2)(j>=h[i],k>=h[i-1]) \] 时间复杂度是1e5*1e2*1e2，空间复杂度是1e5*1e2，显然都过不了 abs很碍眼，所以考虑分两种情况，化简之后就是 \[ f[i][j]=min(f[i-1][k]+k*c)-j*c+(j-h[i])^2(j>=h[i],k>=h[i-1],k>=j) \] \[ f[i][j]=min(f[i-1][k]-k*c)+j*c+(j-h[i])^2(j>=h[i],k>=h[i-1],k<j) \] 然后另开数组ad[i][j]表示i根从j到100最大的f[i][j]+j c，mi[i][j]表示i根从a[i]到j最大的f[i][j]-j c，这个可以在求完f[i][]之后直接扫一遍求出，这样时间复杂度就降为了1e5*1e2 然后发现f,ad,mi的i维都没用，所以直接推掉，空间复杂度就变成了1e2（还有1e5的h数组） 就没了 #include<iostream> #include<cstdio> #include<algorithm> using namespace std; const int N= 100005 ,inf= 1e9 ;
