问题描述
我工作在Android 2.0，我试图接收所有联系人的列表。
I'm working on Android 2.0 and am trying to receive a list of all contacts.
由于 android.provider.Contacts.People 的是德precated，我必须使用的 android.provider.ContactsContract 的，但我不能找到一个合适的例的如何使用它。（例如：检索电话簿所有联系人的列表）
Since android.provider.Contacts.People is deprecated, I have to use android.provider.ContactsContract, But I can't find a proper example of how to use it (ex: retrieve a list of all contacts on the phonebook).
任何人都知道在哪里可以找到这样的例子吗？
Anyone knows where to find such an example?
推荐答案
首先，确保你已经添加
<uses-permission android:name="android.permission.READ_CONTACTS"/>
你的AndroidManifest.xml文件，那么你可以通过这样的手机通讯录循环：
to your AndroidManifest.xml file, then you can loop through your phone contacts like this:
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
while (cursor.moveToNext()) {
String contactId = cursor.getString(cursor.getColumnIndex(
ContactsContract.Contacts._ID));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (Boolean.parseBoolean(hasPhone)) {
// You know it has a number so now query it like this
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));
}
phones.close();
}
Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null);
while (emails.moveToNext()) {
// This would allow you get several email addresses
String emailAddress = emails.getString(
emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
emails.close();
}
cursor.close();
此外，你可以通过你的联系人循环，只是得到这样的姓名和电话号码：
Additionally, you can loop through your contacts and simply get the name and phone number like this:
Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while(people.moveToNext()) {
int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER);
String number = people.getString(numberFieldColumnIndex);
}
people.close();
此外，如果你需要得到的东西就像从一个联系人的笔记，那么你将需要使用不同的URI，如下（随意使用此方法）：
Furthermore, if you need to get things like notes from a contact then you will need to use a different URI, like the following (feel free to use this method):
private String getNote(long contactId) {
String note = null;
String[] columns = new String[] { ContactsContract.CommonDataKinds.Note.NOTE };
String where = ContactsContract.Data.RAW_CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] whereParameters = new String[]{Long.toString(contactId), ContactsContract.CommonDataKinds.Note.CONTENT_ITEM_TYPE};
Cursor contacts = getContentResolver().query(ContactsContract.Data.CONTENT_URI, projection, where, whereParameters, null);
if (contacts.moveToFirst()) {
rv = contacts.getString(0);
}
contacts.close();
return note;
}
注意，这一次我不仅用于接触ID，但MIME类型的查询。
Notice this time I used not only the contact id but the mime type for the query.
