In Android development, reading the phone number in the mobile phone address book is a basic operation. However, due to the large number of Android versions, the operation code in the mobile phone address book is complicated and summarized in this article.

Android1.5 is the lowest version in the current Android system. First, let's talk about the code implementation for android1.5 and later versions (including 2.x, 3.x:

// Obtain all contacts

Cursor cur = context. getcontentresolver (). Query (

Contacts. People. content_uri,

Null,

Null,

Null,

Contacts. People. display_name + "collate localized ASC ");

// Loop Traversal

If (cur. movetofirst ()){

Int idcolumn = cur. getcolumnindex (contacts. People. _ id );

Int displaynamecolumn = cur. getcolumnindex (contacts. People. display_name );

Do {

// Obtain the contact ID

String contactid = cur. getstring (idcolumn );

// Obtain the contact name

String displayname = cur. getstring (displaynamecolumn );

// Obtain the contact's phone number

Cursorphonescur = context. getcontentresolver (). Query (

Contacts. Phones. content_uri, null,

Contacts. Phones. person_id + "=" + contactid, null, null );

If (phonescur. movetofirst ()){

Do {

// Traverse all phone numbers

Stringphonetype = phonescur. getstring (phonescur

. Getcolumnindex (contacts. phonescolumns. Type ));

String phonenumber = phonescur. getstring (phonescur

. Getcolumnindex (contacts. phonescolumns. Number ));

// Your own logic processing code

} While (phonescur. movetonext ());

}

} While (cur. movetonext ());

}

Cur. Close ();

This code can be used to read the phone numbers in the address book of the mobile phone in various versions of Android phones and read multiple numbers under the same name. the efficiency in Version X is not high, and the reading time is longer, and 2. X is currently the mainstream of Android systems, with at least 80% of Android mobile phone shares. Therefore, you can use APIs of higher versions for efficient reading.

The code for reading Address Book for android2.0 and later versions is as follows:

// Read the local phone number of the mobile phone

Contentresolver Cr = context. getcontentresolver ();

// Obtain the cursor of the Start item in the phone book. You must first movetonext ()

Cursor cursor = Cr. Query (contactscontract. Contacts. content_uri, null );

While (cursor. movetonext ()){

// Retrieve the contact name index

Int nameindex = cursor. getcolumnindex (phonelookup. display_name );

String name = cursor. getstring (nameindex );

// Obtain the contact's ID index value

String contactid = cursor. getstring (cursor. getcolumnindex (contactscontract. Contacts. _ id ));

// Query the phone number of the contact. For example, you can query email and photo.

Cursor phone = Cr. Query (contactscontract. commondatakinds. Phone. content_uri, null,

Contactscontract. commondatakinds. Phone. contact_id + "="

+ Contactid, null, null); // The first parameter is the phone number to be queried, and the third parameter is the filtering value of a specific person.

// A person may have several numbers

While (phone. movetonext ()){

String phonenumber = phone. getstring (phone. getcolumnindex (contactscontract. commondatakinds. Phone. Number ));

Listname. Add (name );

Listphone. Add (phonenumber );

}

Phone. Close ();

}

Cursor. Close ();

To read the address book in the SIM card, you can use "content: // ICC/ADN" to read the address book. The Code is as follows:

Try {

Intent intent = new intent ();

Intent. setdata (URI. parse ("content: // ICC/ADN "));

Uri uri = intent. getdata ();

Contentresolvercr = context. getcontentresolver ();

Cursor cursor = context. getcontentresolver (). Query (Uri, null );

If (cursor! = NULL ){

While (cursor. movetonext ()){

// Retrieve the contact name index

Int nameindex = cursor. getcolumnindex (phonelookup. display_name );

String name = cursor. getstring (nameindex );

// Obtain the contact's ID index value

String contactid = cursor. getstring (cursor. getcolumnindex (contactscontract. Contacts. _ id ));

// Query the phone number of the contact. For example, you can query email and photo.

Cursor phone = Cr. Query (contactscontract. commondatakinds. Phone. content_uri, null,

Contactscontract. commondatakinds. Phone. contact_id + "="

+ Contactid, null, null); // The first parameter is the phone number to be queried, and the third parameter is the filtering value of a specific person.

// A person may have several numbers

While (phone. movetonext ()){

String phonenumber = phone. getstring (phone. getcolumnindex (contactscontract. commondatakinds. Phone. Number ));

// Your own logic code

}

Phone. Close ();

}

Cursor. Close ();

}

} Catch (exception e ){}
