android 怎么获取手机联系人csdn

Answer 1

可以参考如下信息，读取手机联系人，不过事先需要权限：
/*
* 读取联系人的信息
*/
public void testReadAllContacts() {
Cursor cursor = this.getContext().getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
int contactIdIndex = 0;
int nameIndex = 0;

if(cursor.getCount() > 0) {
contactIdIndex = cursor.getColumnIndex(ContactsContract.Contacts._ID);
nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
}
while(cursor.moveToNext()) {
String contactId = cursor.getString(contactIdIndex);
String name = cursor.getString(nameIndex);
Log.i(TAG, contactId);
Log.i(TAG, name);

/*
* 查找该联系人的phone信息
*/
Cursor phones = this.getContext().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId,
null, null);
int phoneIndex = 0;
if(phones.getCount() > 0) {
phoneIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
}
while(phones.moveToNext()) {
String phoneNumber = phones.getString(phoneIndex);
Log.i(TAG, phoneNumber);
}

/*
* 查找该联系人的email信息
*/
Cursor emails = this.getContext().getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + "=" + contactId,
null, null);
int emailIndex = 0;
if(emails.getCount() > 0) {
emailIndex = emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
}
while(emails.moveToNext()) {
String email = emails.getString(emailIndex);
Log.i(TAG, email);
}

}
}
