android 在手機中預置連絡人/Service Number

實現預置連絡人（包含姓名、號碼資訊）至手機中；並保證該連絡人是唯讀，無法被刪除/編輯。
                 
代碼分為兩部分：
Part One 將預置的連絡人插入到資料庫中；
Part Two 實現在連絡人詳情和連絡人多選介面中無法刪除/編輯預置連絡人。
【注意】如果您不需要限制預置連絡人的刪除/編輯操作，那麼僅加入Part One部分代碼即可，並去掉第三步”新增函數“  中的語句：contactvalues.put(RawContacts.IS_SDN_CONTACT, -1);
 

File：alps\packages\apps\Contacts\src\com\mediatek\contacts\simcontact\AbstractStartSIMService.java
 
1.引入包
import android.provider.ContactsContract.PhoneLookup;
 
2.增加變數
private static boolean sIsRunningNumberCheck = false;
private static final int INSERT_PRESET_NUMBER_COUNT = xxx;           //預置連絡人的個數
private static final String  INSERT_PRESET_NAME[]    = {"xxx1","xxx2",...};  //各預置連絡人的姓名
private static final String  INSERT_PRESET_NUMBER[] = {"xxx1","xxx2",...};  //各預置連絡人的號碼
 
3.增加函數（將預置連絡人資訊寫入資料庫中）：
  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, null, null);
                try {
                    if (contactCursor != null && contactCursor.getCount() > 0) {
                        return;
                    } else {
                        final ArrayList<ContentProviderOperation> operationList = new ArrayList<ContentProviderOperation>();
                        ContentProviderOperation.Builder 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();
                    }
                }
              }//for
              Log.i(TAG, "isRunningNumberCheck insert: " + sIsRunningNumberCheck);
              sIsRunningNumberCheck = false;
          }
      }).start();
 
  }
  
4.onStart中調用這個函數:
 
    public void onStart(Intent intent, int startId) {
        .....          
        //add by MTK---Preset Contacts
        importDefaultReadonlyContact();
          
        log("[onStart]" + intent + ", startId " + startId);
        if (intent == null) {
            return;
        }
        .....
}
 
 
Part Two
1.File:DefaultContactListAdapter.java  Path:alps\packages\apps\contacts\src\com\android\contacts\list
configureSelection函數中有五處 RawContacts.IS_SDN_CONTACT + " = 0"，都改為：RawContacts.IS_SDN_CONTACT + " < 1"
 
2.File:ProfileAndContactsLoader.java  Path:alps\packages\apps\contacts\src\com\android\contacts\list
loadSDN函數中有兩處 RawContacts.IS_SDN_CONTACT + " = 0"，都改為：RawContacts.IS_SDN_CONTACT + " < 1"
 
3. File:Contact.java  Path:alps\packages\apps\contacts\src\com\android\contacts\model
增加如下函數：
    //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
將isContactEditable函數修改為：
   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 
在檔案最後增加以下代碼：
    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
引入如下包：
import com.mediatek.contacts.list.ContactsMultiDeletionFragment;
 
在onCreateLoader函數中，倒數第二句mAdapter.configureLoader(loader, directoryId);之前增加語句：  
            mAdapter.setShowReadOnlyContact((this instanceof ContactsMultiDeletionFragment) ? false : true);
 
8 7.File:MultiContactsBasePickerAdapter.java Path:alps\packages\apps\contacts\src\com\mediatek\contacts\list  在configureSelection函數最後的語句 loader.setSelection(selection.toString());之前增加語句：
        if (!showReadOnlyContact ) {
            selection.append(" AND " + Contacts.IS_SDN_CONTACT + "=0");
        }
