Android phone preset contact/service number

Implement preset contacts (including names and numbers) to the mobile phone. Ensure that the contacts are read-only and cannot be deleted or edited.

The code is divided into two parts:
Part One inserts the preset contacts into the database;
In Part Two mode, you cannot delete or edit a preset contact on the contact details and contact multi-choice interface.
[Note] If you do not need to restrict the delete/edit operations of the preset contact, add only part of the Part One code and remove the statement contactvalues in step 3 "add function. put (rawcontacts. is_sdn_contact,-1 );

1. Import package
Import Android. provider. contactscontract. phonelookup;
 
2. Add variable
Private Static Boolean sisrunningnumbercheck = false;
Private Static final int insert_preset_number_count = xxx; // Number of Preset contacts
Private Static final string insert_preset_name [] = {"XXX1", "xxx2",...}; // name of each preset contact
Private Static final string insert_preset_number [] = {"XXX1", "xxx2",...}; // The number of each preset contact
 
3. Add a function (write the preset contact information to the database ):
Private void importdefaultreadonlycontact (){
New thread (New runnable (){
 
@ Override
Public void run (){
Log. I (TAG, "isrunningnumbercheck before:" + sisrunningnumbercheck );
If (sisrunningnumbercheck ){
Return;
}
Sisrunningnumbercheck = true;
For (INT I = 0; I <insert_preset_number_count; I ++)
{
Log. I (TAG, "isrunningnumbercheck after:" + sisrunningnumbercheck );
Uri uri = URI. withappendedpath (phonelookup. content_filter_uri, Uri
. Encode (insert_preset_number [I]);
Log. I (TAG, "getcontactinfobyphonenumbers (), uri =" + URI );
 
Cursor contactcursor = getcontentresolver (). Query (Uri, new string [] {
Phonelookup. display_name, phonelookup. photo_id
}, Null );
Try {
If (contactcursor! = NULL & contactcursor. getcount ()> 0 ){
Return;
} Else {
Final arraylist <contentprovideroperation> operationlist = new arraylist <contentprovideroperation> ();
Contentprovideroperation. Builder = contentprovideroperation
. Newinsert (rawcontacts. content_uri );
Contentvalues contactvalues = new contentvalues ();
Contactvalues. Put (rawcontacts. account_name,
Accounttype. account_name_local_phone );
Contactvalues. Put (rawcontacts. account_type,
Accounttype. account_type_local_phone );
Contactvalues. Put (rawcontacts. indicate_phone_sim,
Contactscontract. rawcontacts. indicate_phone );
Contactvalues. Put (rawcontacts. is_sdn_contact,-1 );
Builder. withvalues (contactvalues );
Builder. withvalue (rawcontacts. aggregation_mode,
Rawcontacts. aggregation_mode_disabled );
Operationlist. Add (builder. Build ());
 
Builder = contentprovideroperation. newinsert (data. content_uri );
Builder. withvaluebackreference (phone. raw_contact_id, 0 );
Builder. withvalue (data. mimetype, phone. content_item_type );
Builder. withvalue (phone. type, phone. type_mobile );
Builder. withvalue (phone. Number, insert_preset_number [I]);
Builder. withvalue (data. is_primary, 1 );
Operationlist. Add (builder. Build ());
 
Builder = contentprovideroperation. newinsert (data. content_uri );
Builder. withvaluebackreference (structuredname. raw_contact_id, 0 );
Builder. withvalue (data. mimetype, structuredname. content_item_type );
Builder. withvalue (structuredname. display_name, insert_preset_name [I]);
Operationlist. Add (builder. Build ());
 
Try {
Getcontentresolver (). applybatch (
Contactscontract. Authority, operationlist );
} Catch (RemoteException e ){
Log. E (TAG, String. Format ("% s: % s", E. tostring (), E. getmessage ()));
} Catch (operationapplicationexception e ){
Log. E (TAG, String. Format ("% s: % s", E. tostring (), E. getmessage ()));
}
 
}
} Finally {
// When this service start, but the contactsprovider has not been started yet.
// The contactcursor perhaps null, but not always. (First load will weekup the provider)
// So add null block to avoid nullpointerexception
If (contactcursor! = NULL ){
Contactcursor. Close ();
}
}
} //
Log. I (TAG, "isrunningnumbercheck insert:" + sisrunningnumbercheck );
Sisrunningnumbercheck = false;
}
}). Start ();
 
}

4. onstart calls this function:
 
Public void onstart (intent, int startid ){
.....
// Add By MTK --- preset contacts
Importdefaultreadonlycontact ();

Log ("[onstart]" + intent + ", startid" + startid );
If (intent = NULL ){
Return;
}
.....
}
 
 
Part Two
1. File: defacontcontactlistadapter. Java path: Alps \ packages \ apps \ contacts \ SRC \ com \ Android \ contacts \ list
The configureselection function contains five rawcontacts. is_sdn_contact + "= 0", all of which are changed to rawcontacts. is_sdn_contact + "<1"
 
2. File: profileandcontactsloader. Java path: Alps \ packages \ apps \ contacts \ SRC \ com \ Android \ contacts \ list
The loadsdn function contains rawcontacts. is_sdn_contact + "= 0", both of which are changed to rawcontacts. is_sdn_contact + "<1"
 
3. File: contact. Java path: Alps \ packages \ apps \ contacts \ SRC \ com \ Android \ contacts \ Model
Add the following functions:
// Add By MTK --- preset contacts
Public Boolean isreadonlycontact (){
Return missdncontact =-1;
}
 
4. File: contactloaderfragment. Java path: Alps \ packages \ apps \ contacts \ SRC \ com \ Android \ contacts \ detail
Modify the iscontacteditable function:
Public Boolean iscontacteditable (){
Return mcontactdata! = NULL &&! Mcontactdata. isdirectoryentry ()
&&! Mcontactdata. issdncontacts ()&&! Mcontactdata. isreadonlycontact ();
}
 
5. File: contactentrylistadapter. Java path: Alps \ packages \ apps \ contacts \ SRC \ com \ Android \ contacts \ list
Add the following code at the end of the file:
Public Boolean showreadonlycontact = true;
Public void setshowreadonlycontact (Boolean candelete ){
Showreadonlycontact = candelete;
}
 
6. File: contactentrylistfragment. Java path: Alps \ packages \ apps \ contacts \ SRC \ com \ Android \ contacts \ list
Introduce the following package:
Import com. mediatek. Contacts. List. contactsmultideletionfragment;
 
In the oncreateloader function, add the following statement to the penultimate sentence madapter. configureloader (loader, directoryid:
Madapter. setshowreadonlycontact (this instanceof contactsmultideletionfragment )? False: True );
 
8 7. file: multicontactsbasepickeradapter. java path: Alps \ packages \ apps \ contacts \ SRC \ com \ mediatek \ contacts \ list the Final Statement loader in the configureselection function. setselection (selection. tostring (); previously added the statement:
If (! Showreadonlycontact ){
Selection. append ("and" + contacts. is_sdn_contact + "= 0 ");
}
