android获取通讯录信息

开发中需要获取手机用户的通讯录信息，要求运行在Andrid2.0及以上版本，因为程序中用到了Android2.0新的API。程序运行结果通过Log.v写入到了日志，结果部分截图：

程序的主要代码如下：
protected void getContactInfo() {
//获得通讯录信息 ，URI是ContactsContract.Contacts.CONTENT_URI
Cursor cursor = getContentResolver().query(

ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

while (cursor.moveToNext()) {
//获得通讯录中每个联系人的ID

String contactId = cursor.getString(cursor

.getColumnIndex(ContactsContract.Contacts._ID));
//获得通讯录中联系人的名字

String name = cursor

.getString(cursor

.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));

Log.v(TAG, "…name…" + name);
//查看给联系人是否有电话，返回结果是String类型，1表示有，0表是没有

String hasPhone = cursor

.getString(cursor

.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (hasPhone.equalsIgnoreCase("1"))

hasPhone = "true";

else

hasPhone = "false";
//如果有电话，根据联系人的ID查找到联系人的电话，电话可以是多个
if (Boolean.parseBoolean(hasPhone)) {

Cursor phones = getContentResolver().query(

ContactsContract.CommonDataKinds.Phone.CONTENT_URI,

null,

ContactsContract.CommonDataKinds.Phone.CONTACT_ID

+ " = " + contactId, null, null);

while (phones.moveToNext()) {

String phoneNumber = phones

.getString(phones

.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

Log.v(TAG, "…phoneNumber… " + phoneNumber);

}

phones.close();

}
//查找email地址，这里email也可以有多个
Cursor emails = getContentResolver().query(

ContactsContract.CommonDataKinds.Email.CONTENT_URI,

null,

ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = "

+ contactId, null, null);

while (emails.moveToNext()) {

String emailAddress = emails

.getString(emails

.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));

Log.v(TAG, "…emailAddress… " + emailAddress);

}

emails.close();
//获得联系人的地址
Cursor address = getContentResolver()

.query(ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,

null,

ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID

+ " = " + contactId, null, null);

while (address.moveToNext()) {

// These are all private class variables, don’t forget to create

// them.

String poBox = address

.getString(address

.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX));

String street = address

.getString(address

.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));

String city = address

.getString(address

.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));

String state = address

.getString(address

.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));

String postalCode = address

.getString(address

.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));

String country = address

.getString(address

.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY));

String type = address

.getString(address

.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.TYPE));

Log.v(TAG, "…city… " + city);

}

}

cursor.close();

}
代码中已经有了注释，这里不做过多解释，比较重要的方法getContentResolver().query在文章Android简单操作sqlite 中有解释。
不要忘记在AndroidMainfest.xml中加入相应的权限：
