如何在 Android 2.0上阅读联系人

First, ensure that you have added

<uses-permission android:name="android.permission.READ_CONTACTS"/>

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();

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();

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;
}

Notice this time I used not only the contact id but the mime type for the query.

This part wouldn't work for me:

 while (phones.moveToNext()) {
String phoneNumber = phones.getString(
phones.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
}

If I use this, though, it does:

 while (phones.moveToNext()) {
String pdata = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA));
Log.v("DATA",pdata);
}

Great to see some useful info, it is frustrating how poorly this important topic is covered by docs and such. After too much hacking about I thought I would share a little code also. The following code is a little prettier and get the same thing done more efficiently.

Uri contactUri = ContactsContract.Contacts.CONTENT_URI;


String[] PROJECTION = new String[] {


ContactsContract.Contacts._ID,


ContactsContract.Contacts.DISPLAY_NAME,


ContactsContract.Contacts.HAS_PHONE_NUMBER,


};


String SELECTION = ContactsContract.Contacts.HAS_PHONE_NUMBER + "='1'";


Cursor contacts = managedQuery(contactUri, PROJECTION, SELECTION, null, null );

The above chunk of code returns a Cursor that points to the resulting query that only contains those rows that have a phone number. This is nice since you typically have many contacts without numbers. Furthermore, the PROJECTION limits the amount of data that is returned.

String key, value, phoneNumber;


Hashtable contactPhoneInfo = new Hashtable<String, String>();


Uri phoneUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;


String [] PHONES_PROJECTION = new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER };


String PHONE_SELECTION = null;


contacts.moveToFirst();


do{


long contactId = contacts.getLong(idColumnIndex);


PHONE_SELECTION = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId;


Cursor phones = managedQuery(phoneUri,
PHONES_PROJECTION,
null,
null,
ContactsContract.CommonDataKinds.Phone.IS_SUPER_PRIMARY + " DESC");




phones.moveToFirst();


key = phones.getString(0).replaceAll("\\D", "");


value = contacts.getString(nameColumnIndex);


contactPhoneInfo.put(key, value);


}while(contacts.moveToNext());


contacts.close();
}

The above chunk gets the phone number associated with each contact id that has a phone number. I store all the info in a hash table and with a key value of the phone number. I stripped the phone number of all none digit info also. For some reason even though ContactsContract.CommonDataKinds.Phone.HAS_PHONE_NUMBER is valid if you include that in the projection argument it breaks the query, I don't know why and it is frustrating that it does.

The second part of the code above is too slow, all the query calls just bog everything down. The following code is much faster. Just grab all the rows for the phone content and use the contact_ids to sort the data you want.

Cursor phones = managedQuery(phoneUri,
PHONES_PROJECTION,
PHONE_SELECTION,
null,
ContactsContract.CommonDataKinds.Phone.IS_SUPER_PRIMARY + " DESC");


contacts.moveToFirst();


do{


value = "";


key = contacts.getString(idColumnIndex);


contactPhoneInfo.put(key, value);


}while(contacts.moveToNext());


phones.moveToFirst();


Set keySet = contactPhoneInfo.keySet();


idColumnIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID);


int numColumnIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);


do{


key = phones.getString(idColumnIndex);


if(keySet.contains(key)){


value = phones.getString(numColumnIndex).replaceAll("\\D", "");


contactPhoneInfo.put(key, value);


}




}while(phones.moveToNext());

You end up with a hashtable with all the info you want in it. Of course you could put whatever info you want into the data structure. The second way of doing it is much much faster.

You can use "ContactManager" example from android developer's site (OR) Go to the location where you have set the path to download android-sdk in your system. In android-sdk-mac_x86/samples/android-10 folder, you can see "ContactManager" example.

I have tried using this example, worked well in my application.

Just want to add, when you are retrieving the contacts you might get a lot of "garbage" contacts - for example some email addresses that a user has at some point send an email to, but are not aggregated... If you want only the contacts visible to the user, as in the Androids own contacts application you need to restrict the selection to only IN_VISIBLE_GROUP.

    String where = ContactsContract.Contacts.IN_VISIBLE_GROUP + "= ? ";
String[] selectionArgs = new String[] { "1" };

I think it is important to have the code from this URL http://coderzheaven.com/2011/06/get-all-details-from-contacts-in-android/ on StackOverflow cause at times links like that go down.

Put this ....

Cursor phones =


getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
while (phones.moveToNext())
{
String Name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

Let me know if any issue.

I found very easy solution to read contacts. (boring to write code for reading each value so it's good to use wrapper class for contacts)

I'm using Samsung Galaxy Note 4, and I donno why none of the above worked for me. I mixed up some and made this woking..

    Cursor people = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
people.moveToFirst();
while(people.moveToNext()) {
int nameFieldColumnIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
int numberFieldColumnIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA);
String number = people.getString(numberFieldColumnIndex);
dbWriter.execSQL("Insert Into ContactsList (ContactName, ContactNumber) Values (" +
"'" + contact.replace("'",  "''") + "', '" + number.replace("'",  "''") + "')");
}
people.close();
