Android通讯录管理（获取联系人、通话记录、短信消息）

2014年2月26日通讯录开发研究学习

前言：前阵子主要是记录了如何对联系人的一些操作，比如搜索，全选、反选和删除等在实际开发中可能需要实现的功能，本篇博客是小巫从一个别人开源的一个项目抽取出来的部分内容，把它给简化出来，可以让需要的朋友清楚知道如何对Android数据库操作，异步查询数据库获取我们需要的内容。由于内容比较多，我将分三篇博客来讲述获取联系人、通话记录、短信消息的实现。

也许你根本就没耐心看，源码在这里http://download.csdn.net/detail/wwj_748/6962865，骚年去下吧。

上面的是获取联系人的界面效果，实现分组显示联系人，快速索引条查找联系人，下面是实现：

从权限开始：
[html] view plain copy print ?

<!– 读联系人权限 –>
<uses-permission android:name=“android.permission.READ_CONTACTS” />
<!– 写联系人权限 –>
<uses-permission android:name=“android.permission.WRITE_CONTACTS” />
<!– 拨号权限 –>
<uses-permission android:name=“android.permission.CALL_PHONE” />
<!– 读短信权限 –>
<uses-permission android:name=“android.permission.READ_SMS” />

<!-- 读联系人权限 -->
<uses-permission android:name="android.permission.READ_CONTACTS" />
<!-- 写联系人权限 -->
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<!-- 拨号权限 -->
<uses-permission android:name="android.permission.CALL_PHONE" />
<!-- 读短信权限 -->
<uses-permission android:name="android.permission.READ_SMS" />

界面布局：

代码实现：

1. 先定义一个实体类，用来保存联系人信息
/Contact_Demo/src/com/suntek/contact/model/ContactBean.java

[java] view plain copy print ?

package com.suntek.contact.model; public class ContactBean { private int contactId; //id private String desplayName;//姓名 private String phoneNum; // 电话号码 private String sortKey; // 排序用的 private Long photoId; // 图片id private String lookUpKey; private int selected = 0; private String formattedNumber; private String pinyin; // 姓名拼音 public int getContactId() { return contactId; } public void setContactId(int contactId) { this.contactId = contactId; } public String getDesplayName() { return desplayName; } public void setDesplayName(String desplayName) { this.desplayName = desplayName; } public String getPhoneNum() { return phoneNum; } public void setPhoneNum(String phoneNum) { this.phoneNum = phoneNum; } public String getSortKey() { return sortKey; } public void setSortKey(String sortKey) { this.sortKey = sortKey; } public Long getPhotoId() { return photoId; } public void setPhotoId(Long photoId) { this.photoId = photoId; } public String getLookUpKey() { return lookUpKey; } public void setLookUpKey(String lookUpKey) { this.lookUpKey = lookUpKey; } public int getSelected() { return selected; } public void setSelected(int selected) { this.selected = selected; } public String getFormattedNumber() { return formattedNumber; } public void setFormattedNumber(String formattedNumber) { this.formattedNumber = formattedNumber; } public String getPinyin() { return pinyin; } public void setPinyin(String pinyin) { this.pinyin = pinyin; } }

package com.suntek.contact.model;

public class ContactBean {

private int contactId; //id
private String desplayName;//姓名
private String phoneNum; // 电话号码
private String sortKey; // 排序用的
private Long photoId; // 图片id
private String lookUpKey;
private int selected = 0;
private String formattedNumber;
private String pinyin; // 姓名拼音

public int getContactId() {
return contactId;
}

public void setContactId(int contactId) {
this.contactId = contactId;
}

public String getDesplayName() {
return desplayName;
}

public void setDesplayName(String desplayName) {
this.desplayName = desplayName;
}

public String getPhoneNum() {
return phoneNum;
}

public void setPhoneNum(String phoneNum) {
this.phoneNum = phoneNum;
}

public String getSortKey() {
return sortKey;
}

public void setSortKey(String sortKey) {
this.sortKey = sortKey;
}

public Long getPhotoId() {
return photoId;
}

public void setPhotoId(Long photoId) {
this.photoId = photoId;
}

public String getLookUpKey() {
return lookUpKey;
}

public void setLookUpKey(String lookUpKey) {
this.lookUpKey = lookUpKey;
}

public int getSelected() {
return selected;
}

public void setSelected(int selected) {
this.selected = selected;
}

public String getFormattedNumber() {
return formattedNumber;
}

public void setFormattedNumber(String formattedNumber) {
this.formattedNumber = formattedNumber;
}

public String getPinyin() {
return pinyin;
}

public void setPinyin(String pinyin) {
this.pinyin = pinyin;
}

}
