Android call history and contact Query

From http://blog.csdn.net/davayunhuijia/article/details/7778240

There are three types of call records:

Call: CallLog. CILS. INCOMING_TYPE (Constant Value: 1)

Allocated: CallLog. CILS. OUTGOING_TYPE (Constant Value: 2)

Not connected: CallLog. CILS. MISSED_TYPE (Constant Value: 3)

View the declaration in the source code:

<ProviderAndroid: Name = "CallLogProvider"Android: Authorities = "call_log"Android: Syncable = "false"Android: Multiprocess = "false"Android: ReadPermission ="Android. Permission. READ_CONTACTS"Android: WritePermission ="Android. Permission. WRITE_CONTACTS ">

</Provider>

Permission to be declared

<Uses-permissionAndroid: Name ="Android. Permission. READ_CONTACTS "/>

<Uses-permissionAndroid: Name ="Android. Permission. WRITE_CONTACTS "/>

SystemCall HistoryIs the Uri CallLog. CILS. CONTENT_URI shared externally through ContentProvider:

It is equivalent to Uri. parse ("content: // call_log/CILS ");

Query all records

ContentResolver resolver = getContentResolver (); resolver. query (CallLog. CILS. CONTENT_URI, null, null, new String [] {"15101689022"}, null );

Query all records of a contact by phone number)

Resolver. query (CallLog. CILS. CONTENT_URI, null, "number =? ", New String [] {" 15101689022 "}, null );

Query all unanswered phone records of a contact (by phone number) resolver. query (CallLog. CILS. CONTENT_URI, String [] {"15101689022"}, null );

Delete A contact's most recent call ContentResolver resolver = getContentResolver ();

/* The content provider knowledge is involved here. In fact, operations are directly performed here.
AndroidThe database is very painful */

Cursor cursor = resolver. query (CallLog. CILS. CONTENT_URI, new String [] {"_ id"}, "number =? And (type = 1 or type = 3) ", new String [] {" 15101689022 "}," _ id desc limit 1 "); null," number =? And type = 3 ", new if (cursor. moveToFirst () {int id = cursor. getInt (0); resolver. delete (CallLog. CILS. CONTENT_URI,
"_ Id =? ", New String [] {id + ""});}

The following describes how the code is used.

Let's talk about Phone. CONTENT_URI. When getting a contact, you need to go to the url to find the data. It actually points to "content: // com. android. contacts/data/phones ". This url corresponds to the contacts table, raw_contacts table, and data table. Therefore, our data is obtained from these three tables.

The second query parameter is emphasized here.

Private static final String [] PHONES_PROJECTION = new String [] {

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

It means to only search for the four data shown in the Table: phone number, Avatar ID, and contact ID. If you need other data, modify the data here.

Get Mobile Phone Address Book Contact Information

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

Private void getphonecontacts (){

Contentresolver resolver = mcontext. getcontentresolver ();

// Obtain the mobile phone contact

Cursor phonecursor = resolver. Query (phone. content_uri, phones_projection, 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 );

// Obtain the contact ID

Long contactid = phoneCursor. getLong (PHONES_CONTACT_ID_INDEX );

// Obtain the Contact Profile ID.

Long photoid = 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 (getResources (), R. drawable. contact_photo );

}

MContactsName. add (contactName );

MContactsNumber. add (phoneNumber );

MContactsPhonto. add (contactPhoto );

}

PhoneCursor. close ();

}

}

Get mobile phone SIM card contact information

The SIM card and the mobile phone can be obtained in a similar way, but the url is a little different. Note that the SIM card does not have a contact profile.

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

Private void getSIMContacts (){

ContentResolver resolver = mContext. 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 ();

}
