Method to return contacts phone number always returns null - Android [duplicate]

I am able to retrieve the contact ID, but then later I wish to separately retrieve the phone number based on the contact ID. The code below is returning a null result for the phone number. (I do wish later to retrieve the name and phone number together and populate a view, but I am just trying to get the phone number to work first).
In my onCreate I have this code
String phoneNum = getPhoneNumber(myID);
TextView phoneTextView = (TextView) findViewById(R.id.textViewPhone);
phoneTextView.setText(phoneNum);
This is the method for getPhoneNumber()
protected String getPhoneNumber(String id) {
ArrayList<String> phones = new ArrayList<String>();
Cursor cursor = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id}, null);
while (cursor.moveToNext()) {
phones.add(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
}
cursor.close();
String phoneNum;
phoneNum = phones.get(0);
return phoneNum;
}//end getPhoneNumber();
}
This produces the error java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0, which I plan on creating some error handling for. But still, I am certain I have the ID from the previous code, so I don't know why the ArrayList returns null. If you would like to see that code, it is also in my onCreate:
Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
if (cursor.getCount() != 0) {
int numContacts = cursor.getCount();
ArrayList<String> idList = new ArrayList<>();
Random rand = new Random();
int randomNum = rand.nextInt(numContacts);
while (cursor.moveToNext()) {
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
idList.add(id);
}
myID = idList.get(randomNum);
String myString = Integer.toString(randomNum);
TextView myTextView = (TextView) findViewById(R.id.textViewID);
myTextView.setText(myString);
if (myID != null) {
myTextView.setText(myID);
} else {
myTextView.setText("Try Again!");
}
} else {
Toast.makeText(getApplicationContext(), "Your have no contacts.", Toast.LENGTH_SHORT).show();
}
cursor.close();

// You can fetch the Contact Number and Email With Following Methods.
String phone = getPhoneNumber(ContactId);
String email = getEmail("" + ContactId);
private String getPhoneNumber(long id) {
String phone = null;
Cursor phonesCursor = null;
phonesCursor = queryPhoneNumbers(id);
if (phonesCursor == null || phonesCursor.getCount() == 0) {
// No valid number
//signalError();
return null;
} else if (phonesCursor.getCount() == 1) {
// only one number, call it.
phone = phonesCursor.getString(phonesCursor
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
} else {
phonesCursor.moveToPosition(-1);
while (phonesCursor.moveToNext()) {
// Found super primary, call it.
phone = phonesCursor.getString(phonesCursor
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
break;
}
}
return phone;
}
private Cursor queryPhoneNumbers(long contactId) {
ContentResolver cr = getContentResolver();
Uri baseUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI,
contactId);
Uri dataUri = Uri.withAppendedPath(baseUri,
ContactsContract.Contacts.Data.CONTENT_DIRECTORY);
Cursor c = cr.query(dataUri, new String[]{ContactsContract.CommonDataKinds.Phone._ID, ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.IS_SUPER_PRIMARY, ContactsContract.RawContacts.ACCOUNT_TYPE,
ContactsContract.CommonDataKinds.Phone.TYPE,
ContactsContract.CommonDataKinds.Phone.LABEL},
ContactsContract.Data.MIMETYPE + "=?",
new String[]{ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE}, null);
if (c != null && c.moveToFirst()) {
return c;
}
return null;
}
private String getEmail(String id) {
String email = "";
ContentResolver cr = getContentResolver();
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
email = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
// String emailType = emailCur.getString(
// emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
}
emailCur.close();
return email;
}

I have not been able to successfully retrieve code based on the Contact ID - but this post gave me a clue: Retrieving a phone number with ContactsContract in Android - function doesn't work
I have altered my original code to query on DISPLAY_NAME instead and things are working now. Here is the method I am using to retrieve the phone number:
private String retrieveContactNumber(String contactName) {
Log.d(TAG, "Contact Name: " + contactName);
Cursor cursorPhone = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " = ? AND " +
ContactsContract.CommonDataKinds.Phone.TYPE + " = " +
ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE,
new String[]{contactName},
null);
if (cursorPhone.moveToFirst()) {
contactNumber = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
cursorPhone.close();
Log.d(TAG, "Contact Phone Number: " + contactNumber);
return contactNumber;
}

Getting phone number from contacts using ContentProvider - Android

I am making a small app where I can get the contacts of my phone using a content provider and display them in a listview as illustrated.
I want to select a row of the listview and automically make a phone call to that specific contact. I tried some things,but they don't work. Any ideas? Here is my code.
public class MainActivity extends ListActivity implements AdapterView.OnItemClickListener{
ArrayAdapter<String> adapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ContentResolver cr = getContentResolver();
Cursor c = cr.query(ContactsContract.Contacts.CONTENT_URI,
new String[] {ContactsContract.Contacts.DISPLAY_NAME},
null, null, null);
List<String> contacts = new ArrayList<String>();
if (c.moveToFirst()) {
do {
contacts.add(c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));
} while (c.moveToNext());
}
adapter = new ArrayAdapter<String>(this, R.layout.activity_main, contacts);
setListAdapter(adapter);
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//The answer should be inside here.
}
}

First, ensure that you have added the Permission to your AndroidManifest.xml file:
<uses-permission android:name="android.permission.READ_CONTACTS"/>
UPDATE:
On Android 6 and higher stating the permission in the manifest is not enough, you have to explicitly ask user for granting permission on reading contacts otherwise, you will get an exception. See this answer for more details.
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(
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();
}

Try with:
private void doMagicContacts() {
Cursor cursor = getContentResolver()
.query(ContactsContract.Contacts.CONTENT_URI,
null,
null,
null,
null);
if (cursor == null) {
return;
}
cursor.moveToFirst();
do {
String name = cursor.getString(
cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String id = cursor.getString(
cursor.getColumnIndex(ContactsContract.Contacts.NAME_RAW_CONTACT_ID));
Cursor phones = getContentResolver()
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.RAW_CONTACT_ID+" = " + id,
null,
null);
if (phones != null) {
while (phones.moveToNext()) {
String phoneNumber = phones.getString(
phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.d(TAG, "doMagicContacts: " + name + " " + phoneNumber);
}
phones.close();
}
} while (cursor.moveToNext());
cursor.close();
}

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...

Fetching contacts in android is very slow

I had written a code to fetch contact name, phone number and image from Contacts and to display it on a listview in android. It's working fine but taking more time to load. I had tried to use multi-threading in some parts of the code. But the loading time is not decreased.
Here is the onCreate() method:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lvDetail = (ListView) findViewById(R.id.listView1);
fetchcontacts();
lvDetail.setAdapter(new MyBaseAdapter(context, myList));
}
Here is the code for fetch contacts:
private void fetchcontacts() {
// TODO Auto-generated method stub
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
int count = cursor.getCount();
if (count > 0) {
Toast.makeText(context, "count >0", Toast.LENGTH_SHORT).show();
while (cursor.moveToNext()) {
String columnId = ContactsContract.Contacts._ID;
int cursorIndex = cursor.getColumnIndex(columnId);
String id = cursor.getString(cursorIndex);
name = cursor.getString(cursor
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Toast.makeText(context, "Toast 1", Toast.LENGTH_SHORT).show();
int numCount = Integer.parseInt(cursor.getString(cursor
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));
if (numCount > 0) {
Toast.makeText(context, "Toast 2", Toast.LENGTH_SHORT).show();
Cursor phoneCursor = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
CommonDataKinds.Phone.CONTACT_ID+" = ?", new String[] { id
}, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
while (phoneCursor.moveToNext()) {
Toast.makeText(context, "Toast 3", Toast.LENGTH_SHORT).show();
phoneNo = phoneCursor.getString(phoneCursor
.getColumnIndex(ContactsContract.CommonDataKinds.
Phone.NUMBER));
String image_uri = phoneCursor
.getString(phoneCursor
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
if (image_uri != null) {
Toast.makeText(context, "Toast 4", Toast.LENGTH_SHORT).show();
System.out.println(Uri.parse(image_uri));
try {
bitmap = MediaStore.Images.Media
.getBitmap(this.getContentResolver(),
Uri.parse(image_uri));
// sb.append("\n Image in Bitmap:" + bitmap);
// System.out.println(bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Toast.makeText(context, name, Toast.LENGTH_SHORT).show();
getDataInList(name,phoneNo,bitmap);
name=null;
phoneNo=null;
Drawable myDrawable = getResources().getDrawable(R.drawable.star1);
bitmap = ((BitmapDrawable) myDrawable).getBitmap();
}
phoneCursor.close();
}
}
}
Here the setAdapter() function of the listview is working after fetching all the contacts to an ArrayList. do anyone have idea about how to display the contacts during fetching contacts? any sample code?

1.Read the Columns from the Cursor which you required only ,According to your requirement you just need _ID,HAS_PHONE_NUMBER,DISPLAY_NAME ,so change the Cursor reading
Cursor cursor = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI,
new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
ContactsContract.Contacts.DISPLAY_NAME }, null, null,
ContactsContract.Contacts.DISPLAY_NAME + " ASC");
2.Dont do the time taking process in the UI thread..Use AsyncTask instead
Note : This two steps will resolve to some extent..but not completely

I made it by reduce repeated query wich is expensive. Best of my solution is that method found all mobile phones and email for each contact and insert to list for every contact values. It is fast as storm now :)
//contact entity
public class MobileContact {
public String name;
public String contact;
public Type type;
public MobileContact(String contact, Type type) {
name = "";
this.contact = contact;
this.type = type;
}
public MobileContact(String name, String contact, Type type) {
this.name = name;
this.contact = contact;
this.type = type;
}
public enum Type {
EMAIL, PHONE
}
#Override
public String toString() {
return "MobileContact{" +
"name='" + name + '\'' +
", contact='" + contact + '\'' +
", type=" + type +
'}';
}
}
// method for collect contacts
public List<MobileContact> getAllContacts() {
log.debug("get all contacts");
List<MobileContact> mobileContacts = new ArrayList<>();
ContentResolver contentResolver = context.getContentResolver();
// add all mobiles contact
Cursor phonesCursor = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.CONTACT_ID}, null, null, null);
while (phonesCursor != null && phonesCursor.moveToNext()) {
String contactId = phonesCursor.getString(phonesCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
String phoneNumber = phonesCursor.getString(phonesCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)).replace(" ", "");
mobileContacts.add(new MobileContact(contactId, phoneNumber, MobileContact.Type.PHONE));
}
if (phonesCursor != null) {
phonesCursor.close();
}
// add all email contact
Cursor emailCursor = contentResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, new String[]{ContactsContract.CommonDataKinds.Email.DATA, ContactsContract.CommonDataKinds.Email.CONTACT_ID}, null, null, null);
while (emailCursor != null && emailCursor.moveToNext()) {
String contactId = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID));
String email = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
mobileContacts.add(new MobileContact(contactId, email, MobileContact.Type.EMAIL));
}
if (emailCursor != null) {
emailCursor.close();
}
// get contact name map
Map<String, String> contactMap = new HashMap<>();
Cursor contactsCursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, new String[]{ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.HAS_PHONE_NUMBER}, null, null, ContactsContract.Contacts.DISPLAY_NAME);
while (contactsCursor != null && contactsCursor.moveToNext()) {
String contactId = contactsCursor.getString(contactsCursor.getColumnIndex(ContactsContract.Contacts._ID));
String contactName = contactsCursor.getString(contactsCursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contactMap.put(contactId, contactName);
}
if (phonesCursor != null) {
phonesCursor.close();
}
// replace contactId to display name
for (MobileContact mobileContact : mobileContacts) {
String displayName = contactMap.get(mobileContact.name);
mobileContact.name = displayName != null ? displayName : "";
}
// sort list by name
Collections.sort(mobileContacts, new Comparator<MobileContact>() {
#Override
public int compare(MobileContact c1, MobileContact c2) {
return c1.name.compareTo(c2.name);
}
});
return mobileContacts;
}

The contacts in larse size use in backround task.
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number[i]));
ContentResolver contentResolver = getContentResolver();
Cursor search = contentResolver.query(uri, new String[]{ContactsContract.PhoneLookup._ID,
ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null);
try {
if (search != null && search.getCount() > 0) {
search.moveToNext();
name = search.getString(search.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
id = search.getString(search.getColumnIndex(ContactsContract.Data._ID));
System.out.println("name" + name + "id" + id);
/* tv_name.setText(name);
tv_id.setText(id);
tv_phone.setText(number);*/
}
} finally {
if (search != null) {
search.close();
}
}

Fastest way for me soo far .
ContentResolver cr = mContext.getContentResolver(); Cursor cursor= mContext.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, PROJECTION, "HAS_PHONE_NUMBER <> 0", null, null); if (cursor!= null) { final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME); final int numberIndex = cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER); final int idIndex= cursor.getColumnIndex(ContactsContract.Contacts._ID); String displayName, number = null, idValue; while (cursor.moveToNext()) {
displayName = cursor.getString(displayNameIndex);
idValue= cursor.getString(idIndex);
Cursor phones = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, "contact_id = '" + idValue + "'", null, null);
phones.moveToFirst();
try {
number = phones.getString(phones.getColumnIndex("data1"));
}
catch (CursorIndexOutOfBoundsException e)
{`
}
phones.close();
userList.add(new ContactModel(displayName , number , null , }

Get contact details from contact id in Android

I want to get several contact details from a contact list view. I have this code:
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long id) {
//HERE I WANT TO GET CONTACT DETAILS FROM THE ID PARAMETER
Uri lookupUri = Uri.withAppendedPath(Contacts.CONTENT_LOOKUP_URI, Uri.encode(id));
Cursor c = getContentResolver().query(lookupUri, new String[]{Contacts.DISPLAY_NAME}, null,null,null);
try {
c.moveToFirst();
String displayName = c.getString(0);
} finally {
c.close();
}
}
But I get this exception: IllegalArgumentException, Invalid lookup id (when I call query method from cursor).
So I dont know how to get a valid lookup id from the item list.
Any idea? thanks!

Here id means, A contact id for which you want to fetch the contact details,
The simply code for getting phone number for a particular contact id is like,
// Build the Uri to query to table
Uri myPhoneUri = Uri.withAppendedPath(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, id);
// Query the table
Cursor phoneCursor = managedQuery(
myPhoneUri, null, null, null, null);
// Get the phone numbers from the contact
for (phoneCursor.moveToFirst(); !phoneCursor.isAfterLast(); phoneCursor.moveToNext()) {
// Get a phone number
String phoneNumber = phoneCursor.getString(phoneCursor
.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));
sb.append("Phone: " + phoneNumber + "\n");
}
}
So, from your question I have to doubt for id parameter which are you sing in your uri just clear that, Also in my example the id is string type...
Hope you will understand it.
Update: Uri.encode(id) instead of just pass id in string format.
Thanks..

Because managedQuery is deprecated you can also use
Cursor phoneCursor = getContentResolver().query(myPhoneUri, null, null, null, null);

Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
int columnIndex = arg2.getColumnIndex(ContactsContract.Contacts._ID);
private void retriveContactImage(ImageView imageView, int columnIndex) {
Bitmap photo = null;
try {
InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(context.getContentResolver(),
ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long.valueOf(columnIndex)));
if (inputStream != null) {
photo = BitmapFactory.decodeStream(inputStream);
inputStream.close();
}
} catch (IOException e) {
e.printStackTrace();
}
imageView.setImageBitmap(photo);
}
private ArrayList<String> retrieveContactNumbers(TextView textView, long contactId) {
ArrayList<String> phoneNum = new ArrayList<String>();
Cursor cursor = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { contactId + "" }, null);
if (cursor.getCount() >= 1) {
while (cursor.moveToNext()) {
// store the numbers in an array
String str = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
if (str != null && str.trim().length() > 0) {
phoneNum.add(str);
}
}
}
cursor.close();
textView.setText(phoneNum.get(0));
return phoneNum;
}
private void retrieveContactName(TextView textView, long contactId) {
String contactName = null;
Cursor cursor = context.getContentResolver().query(Contacts.CONTENT_URI, new String[] { ContactsContract.Contacts.DISPLAY_NAME },
ContactsContract.Contacts._ID + " = ?", new String[] { String.valueOf(contactId) }, null);
if (cursor.moveToFirst()) {
contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
}
cursor.close();
textView.setText(contactName);
}
