How to display Contact No. in Android ?

You can get contact using ContactsContract.And its provide bridge between contact provider and your applications.That contains URIs  and columns to get contact with information.Such as name,street address,city,various type of phone number,email address,postal address,notes,organization.

While retrieving contact, Don’t forgot to add uses-permission

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

you can retrieve all contacts as a cursor.

Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,null, null);

now we have cusror with contacts and get diffrent value from cusror.

while (cursor.moveToNext()) {
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

Above code,get all contact name and phone numbers from your phone and sim.

Get only SimCard’s Contact:

Cursor cursor = mContentResolver.query(RawContacts.CONTENT_URI,new String[]{RawContacts._ID,RawContacts.ACCOUNT_TYPE},
RawContacts.ACCOUNT_TYPE + " <> 'com.anddroid.contacts.sim' "+ " AND " + RawContacts.ACCOUNT_TYPE + " <> '' ",null,null);

we can get diffrent types of phone number from contacts.Like,Home,Mobile,Work.So first you need to get you contact id from cursor.using contact id you can get cursor of phone number.

Get diffrent type of phone number

String contact_Id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
Cursor cursor_phone = getContentResolver().query(Phone.CONTENT_URI, null, Phone.CONTACT_ID + " = " + contact_Id, null, null);
while (cursor_phone.moveToNext()) {
String phNumber = cursor_phone.getString(cursor_phone
int PHONE_TYPE =cursor_phone.getInt(cursor_phone.getColumnIndex(Phone.TYPE));
  switch (PHONE_TYPE) {
    case Phone.TYPE_HOME:
    // home number
   case Phone.TYPE_MOBILE:
    // mobile number
   case Phone.TYPE_WORK:
    // work(office) number

Get Address From your ContactId

while (cursor.moveToNext()) {
   String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));         Cursor address_cursror = getContentResolver().query(ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,null,ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID+ " = ?",
new String[] { id },null);
   while(address_cursror.moveToNext()) {
    String street = address_cursror.getString(address_cursror.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
  String city = address_cursror.getString(address_cursror.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));
 String state = address_cursror.getString(address_cursror.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));
String postalCode = address_cursror.getString(address_cursror.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
