Get contact information for Android Development

For mobile phones, there are two types of contacts: SIM card contacts and built-in mobile phone contacts. Generally, SIM card contacts do not contain more information (such as mailing addresses and portraits), but mobile phone built-in contacts can obtain more information. Basically, this information is bound to a mobile phone account, so that mobile phone users can retrieve lost data. The following describes how to obtain contact information:

Java File Code (Part ):

/** Obtain the Phon table field of the database **/

Private staticfinal String [] PHONES_PROJECTION = new String [] {

Phone. DISPLAY_NAME, Phone. NUMBER, Photo. PHOTO_ID, Phone. CONTACT_ID };

/** Display contact name **/

Privatestatic finalint PHONES_DISPLAY_NAME_INDEX = 0;

/** Phone number **/

Private staticfinal int PHONES_NUMBER_INDEX = 1;

/** Avatar ID **/

Private staticfinal int PHONES_PHOTO_ID_INDEX = 2;

/** Contact ID **/

Privatestatic finalint PHONES_CONTACT_ID_INDEX = 3;

/** Contact name **/

Private ArrayList MContactsName = new ArrayList ();

Public ArrayList GetmContactsName (){

ReturnmContactsName;

}

Public void setmContactsName (ArrayList MContactsName ){

This. mContactsName = mContactsName;

}

Public ArrayList GetmContactsNumber (){

ReturnmContactsNumber;

}

Public void setmContactsNumber (ArrayList MContactsNumber ){

This. mContactsNumber = mContactsNumber;

}

/** Contact profile picture **/

Private ArrayList MContactsNumber = new ArrayList ();

/** Contact profile picture **/

Private ArrayList MContactsPhonto = new ArrayList ();

/** Get the mobile phone Address Book Contact Information **/

Public void getPhoneContacts (){

ContentResolver resolver = context. getContentResolver ();

// Obtain the mobile phone contact

Cursor phoneCursor = resolver. query (Phone. CONTENT_URI,

PHONES_PROJECTION, null );

If (phoneCursor! = Null ){

While (phoneCursor. moveToNext ()){

// Obtain the mobile phone number

String phoneNumber = phoneCursor. getString (PHONES_NUMBER_INDEX );

// When the mobile phone number is empty or empty, the current loop is skipped.

If (TextUtils. isEmpty (phoneNumber ))

Continue;

// Obtain the contact name

String contactName = phoneCursor

. GetString (PHONES_DISPLAY_NAME_INDEX );

/// Obtain the contact ID

// Longcontactid =

// PhoneCursor. getLong (PHONES_CONTACT_ID_INDEX );

//

/// Obtain the Contact Profile ID

// Longphotoid = phoneCursor. getLong (PHONES_PHOTO_ID_INDEX );

//

//// Get the Contact Profile Bitamp

// Bitmap contactPhoto = null;

// If the photoid is greater than 0, it indicates that the contact has an Avatar. If no Avatar is set for this person, a default one is provided.

// If (photoid> 0 ){

// Uri uri = ContentUris. withAppendedId (

// ContactsContract. Contacts. CONTENT_URI, contactid );

// InputStream input = ContactsContract. Contacts

//. OpenContactPhotoInputStream (resolver, uri );

// ContactPhoto = BitmapFactory. decodeStream (input );

//} Else {

// ContactPhoto = BitmapFactory. decodeResource (

// M. getResources (), R. drawable. contact_photo );

//}

MContactsName. add (contactName );

MContactsNumber. add (phoneNumber );

}

PhoneCursor. close ();

}

}

/** Get the contact person information for the SIM card on your mobile phone **/

Public void getSIMContacts (){

ContentResolver resolver = context. getContentResolver ();

// Obtain the Sims Card Contact

Uri uri = Uri. parse ("content: // icc/adn ");

Cursor phoneCursor = resolver. query (uri, PHONES_PROJECTION, null, null,

Null );

If (phoneCursor! = Null ){

While (phoneCursor. moveToNext ()){

// Obtain the mobile phone number

String phoneNumber = phoneCursor. getString (PHONES_NUMBER_INDEX );

// When the mobile phone number is empty or empty, the current loop is skipped.

If (TextUtils. isEmpty (phoneNumber ))

Continue;

// Obtain the contact name

String contactName = phoneCursor

. GetString (PHONES_DISPLAY_NAME_INDEX );

// No contact profile in SIM card

MContactsName. add (contactName );

MContactsNumber. add (phoneNumber );

}

PhoneCursor. close ();

}

}
