Android: How to get contact DisplayName by contact _ID?

folks!
Look I broke my mind with problem -
how get display_name from ContactContract via _ID I got earlier???
Here is the code:
public static long getId(Context context, String number) {
long id = 0;
String displayName;
// define the columns I want the query to return
final String[] projection = new String[] {
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup._ID};
// encode the phone number and build the filter URI
final Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
// query time
final Cursor cursor = context.getContentResolver().query(contactUri, projection, null, null, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
// HERE IS GOOD _ID!
id = cursor.getLong(cursor.getColumnIndex(ContactsContract.PhoneLookup._ID));
Log.d("_TAG_", displayName);
{
//
// v. N-1
//
Cursor cursor2 = context.getContentResolver().query(
contactUri,
projection,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{String.valueOf(id)}, null);
if(cursor2 != null) {
// Cursor valid but string below got error "android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1 : )"
displayName = cursor2.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
Log.d("_TAG_", displayName);
}
}
{
//
// v. N
//
Uri myPhoneUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(String.valueOf(id)));
Cursor phoneCursor = context.getContentResolver().query(
myPhoneUri, null, null, null, null);
for (phoneCursor.moveToFirst(); !phoneCursor.isAfterLast(); phoneCursor.moveToNext()) {
// No steps inside!
String str = phoneCursor.getString(phoneCursor
.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Nickname.NAME));
Log.d(App.LOG_TAG, "ContactUtils.getId: " + str);
}
if(phoneCursor != null) {
phoneCursor.close();
}
}
} else {
Log.d("_TAG_", "Contact Not Found # " + number);
}
cursor.close();
}
return id;
}
"v.N-1" and "v.N" are just 2 ones from a million attempts before.
See - I got _ID, so why it doesn't work back as valid query???

Here is decision i found.
public static String getDisplayName(Context context, long id) {
String displayName = null;
// define the columns I want the query to return
final String[] projection = new String[] {
ContactsContract.Contacts.DISPLAY_NAME,
};
final Cursor cursor = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id + "" }, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
}
cursor.close();
}
return displayName;
}
It works...

Checkable Contact List in Android

I want to make a checkable Contact List that should be stored by the application, allow the users to place checks on some contacts, and store users' preferences.
I want to know whether a preference activity can be used to list all contacts as checkboxes,
or whether a custom listview can allow me to save the users preferences for the app?

you can get contact data with following code:
Cursor cursor = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, null, null,
null, null);
cursor.moveToFirst();
if (cursor.getCount() > 0) {
do {
try {
contactId = cursor
.getString(cursor
.getColumnIndex(ContactsContract.Contacts._ID));
Uri contactUri = ContentUris.withAppendedId(
Contacts.CONTENT_URI,
Long.parseLong(contactId));
Uri dataUri = Uri.withAppendedPath(contactUri,
Contacts.Data.CONTENT_DIRECTORY);
Cursor phones = getContentResolver()
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = " + contactId,
null, null);
if (phones.getCount() > 0) {
try {
Cursor nameCursor = getContentResolver()
.query(dataUri,
null,
Data.MIMETYPE + "=?",
new String[] { StructuredName.CONTENT_ITEM_TYPE },
null);
nameCursor.moveToFirst();
do {
String firstName = nameCursor
.getString(nameCursor
.getColumnIndex(Data.DATA2));
String displayname = cursor
.getString(cursor
.getColumnIndex(Contacts.DISPLAY_NAME_ALTERNATIVE));
lastName = nameCursor
.getString(nameCursor
.getColumnIndex(Data.DATA3));
} while (nameCursor.moveToNext());
nameCursor.close();
} catch (Exception e) {
}
}
phones.close();
}
catch (Exception t) {
}
} while (cursor.moveToNext());
}
after get list of your contact name or anything that you want you need create custom adapter to show this data, for creating the custom list see this link and this.
//////////////////////
EDIT:
you can get phone number with following code:
String number = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

Fetching all Contacts and showing them in listview

I am showing all contacts in listview and it is working great. But I also want to add image to listview. Searched alot but didn't find any good tutorial. Please suggest some tutorials for showing contact images on listview. Following is my code.
Cursor cur = getContacts();
ListView lv = getListView();
String[] fields = new String[] {ContactsContract.Data.DISPLAY_NAME };
adapter = new SimpleCursorAdapter(this,
R.layout.contacts_list_row, cur, fields,
new int[] { R.id.title}, 0);
lv.setAdapter(adapter);
getContacts()
private Cursor getContacts() {
// Run query
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME };
String selection = null;
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
return managedQuery(uri, projection, selection, selectionArgs,
sortOrder);
}
Thanks in advance :)

Write a custom list view with ImageView and TextView and get the contact icon image from the Content provider using the bellow code
/**
* #return the photo URI
*/
public Uri getPhotoUri() {
try {
Cursor cur = this.ctx.getContentResolver().query(
ContactsContract.Data.CONTENT_URI,
null,
ContactsContract.Data.CONTACT_ID + "=" + this.getId() + " AND "
+ ContactsContract.Data.MIMETYPE + "='"
+ ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE + "'", null,
null);
if (cur != null) {
if (!cur.moveToFirst()) {
return null; // no photo
}
} else {
return null; // error in cursor process
}
} catch (Exception e) {
e.printStackTrace();
return null;
}
Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long
.parseLong(getId()));
return Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}
And then check the condition image is available then set to imageview
Uri u = objItem.getPhotoUri();
if (u != null) {
mPhotoView.setImageURI(u);
} else {
mPhotoView.setImageResource(R.drawable.defaultimage);
}

I don't know if you will find a tutorial on how to add images with a Simple adapter...you will probably need to create a custom list adapter.
it's really easy and gives you a huge amount of flexibility. try this that should give a decent starting point.
You will need to create a layout that has an ImageView, and the name, then in the adapter you can set the images and names etc.

Android Contacts provider get only phone contacts with all emails

I need to get all phone contacts and their email address and photo uri:
This is what am doing:
private void getContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(Contacts.CONTENT_URI, null, null, null, Contacts.DISPLAY_NAME);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
// if
// (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)))
// > 0) {
Contact contact = new Contact();
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
Uri uri = getContactPhotoUri(Long.parseLong(id));
// set photoUri
contact.setContactPhotoUri(uri);
// set name
contact.setContactName(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));
// get the phone number
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);
while (pCur.moveToNext()) {
// set phone munber
contact.setContactNumber(pCur.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
contacts.add(contact);
}
pCur.close();
// get email and type
Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[] { id }, null);
while (emailCur.moveToNext()) {
// This would allow you get several email addresses
// if the email addresses were stored in an array
// set email
contact.setContactEmail(emailCur.getString(emailCur
.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)));
contacts.add(contact);
}
emailCur.close();
}
}
cur.close();
contactAdapter = new ContactAdapter(this, R.id.contactList, contacts);
// }
}
public Uri getContactPhotoUri(long contactId) {
Uri photoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);
photoUri = Uri.withAppendedPath(photoUri, Contacts.Photo.CONTENT_DIRECTORY);
return photoUri;
}
My problem am getting all contacts including gmail contacts, i dont want gmail contacts to be included. And the time taken is also very slow. How do i optimize this, I know its taking time coz i am using many cursors.. but dont know how to make a single cusror that can give me name email number photo uri ...Thanks!
UPDATED FINAL:
private void getContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(Data.CONTENT_URI, new String[] { Data.CONTACT_ID, Data.MIMETYPE, Email.ADDRESS,
Contacts.DISPLAY_NAME, Phone.NUMBER }, null, null, Contacts.DISPLAY_NAME);
Contact contact;
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(Data.CONTACT_ID));
String mimeType = cur.getString(cur.getColumnIndex(Data.MIMETYPE));
if (allContacts.containsKey(id)) {
// update contact
contact = allContacts.get(id);
} else {
contact = new Contact();
allContacts.put(id, contact);
// set photoUri
contact.setContactPhotoUri(getContactPhotoUri(Long.parseLong(id)));
}
if (mimeType.equals(StructuredName.CONTENT_ITEM_TYPE))
// set name
contact.setContactName(cur.getString(cur.getColumnIndex(Contacts.DISPLAY_NAME)));
if (mimeType.equals(Phone.CONTENT_ITEM_TYPE))
// set phone munber
contact.setContactNumber(cur.getString(cur.getColumnIndex(Phone.NUMBER)));
if (mimeType.equals(Email.CONTENT_ITEM_TYPE))
// set email
contact.setContactEmail(cur.getString(cur.getColumnIndex(Email.ADDRESS)));
}
}
cur.close();
// get contacts from hashmap
contacts.clear();
contacts.addAll(allContacts.values());
// remove null contacts
for (Contact _contact : contacts) {
if (_contact.getContactName() == null && _contact.getContactNumber() == null
&& _contact.getContactEmail() == null) {
contacts.remove(_contact);
break;
}
}
contactAdapter = new ContactAdapter(this, R.id.contactList, contacts);
contactAdapter.notifyDataSetChanged();
}
public Uri getContactPhotoUri(long contactId) {
Uri photoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);
photoUri = Uri.withAppendedPath(photoUri, Contacts.Photo.CONTENT_DIRECTORY);
return photoUri;
}

You should be able to get all the information needed in one query on Data.CONTENT_URI,
Check out "android.provider.ContactsContract.Data" table and the examples on how to query different types of data Email,Phone,Photo etc...
http://developer.android.com/reference/android/provider/ContactsContract.Data.html
For example:
Cursor data = cntx.getContentResolver().query(Data.CONTENT_URI, new String[] {Data._ID,Data.MIMETYPE,Email.ADDRESS,Photo.PHOTO},Data.CONTACT_ID + "=?" + " AND " + "(" + Data.MIMETYPE + "='" + Photo.CONTENT_ITEM_TYPE + "' OR " + Data.MIMETYPE + "='" + Email.CONTENT_ITEM_TYPE +"')",
new String[] {String.valueOf(contactId)}, null);
Should bring you all the information you need regarding one specific contactId, you could theoretically ask for all contacts and sort the information yourself.
As for filtering gmail contacts this is a more complex issue, take a look at ACCOUNT_NAME / TYPE http://developer.android.com/reference/android/provider/ContactsContract.RawContacts.html
parameter and a discussion regarding this issue here:
What is the default Account Type / Name for contacts on Android Contact Application?

how to read and write Android myself contact

I am working with Android contacts, which is Android 4.0.3. In the contact app, I can create, add, edit and see myself contact in it. But when I tried to get myself contact from my app using contentResolver, it did not work. How can I read and write myself contact?
Thanks in advance.
EDIT: here is my code to get contacts
List list = new ArrayList();
Uri uri = Contacts.CONTENT_URI;
String[] projection = new String[] {
Contacts._ID,
Contacts.LOOKUP_KEY,
Contacts.DISPLAY_NAME,
Contacts.HAS_PHONE_NUMBER,
Contacts.PHOTO_ID,
Contacts.LAST_TIME_CONTACTED,
Contacts.TIMES_CONTACTED
};
String sortOrder = Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
if (sortColumn != null) {
if (sortColumn.equals(Contacts.LAST_TIME_CONTACTED) || sortColumn.equals(Contacts.TIMES_CONTACTED))
sortOrder = "" + sortColumn + " COLLATE LOCALIZED DESC";
}
Cursor cursor = null;
try {
cursor = context.getContentResolver().query(uri, projection, null, null, sortOrder);
while (cursor.moveToNext()){
list.add(getRecord(context, cursor));
}
return list;
} finally {
if (cursor!=null) cursor.close();
}

Try this Uri below.
Uri uri = Uri.withAppendedPath(
ContactsContract.Profile.CONTENT_URI,
ContactsContract.Contacts.Data.CONTENT_DIRECTORY);
This is the path of "Myself".
