JB版本：
1.SIM/USIM卡联系人：可以直接使用EditSimContactActivity中的USIM_EMAIL_PATTERN，搜索与“USIM_EMAIL_PATTERN”，将相关code所加的注释去掉即可


2.手机本地联系人：修改代码如下

ContactEditorFragment.java (packages\apps\contacts\src\com\android\contacts\editor)

A 引入包
import java.util.regex.Pattern;
B 增加变量
private static final String USIM_EMAIL_PATTERN = "0-9][a-z][A-Z][_0-9][a-z][A-Z][-_.*@0-9][a-z][A-Z][-_.+";
C save函数中，
在如下语句：

if (!hasValidState() || mStatus != Status.EDITING) {

             Log.i(TAG, "[save] !hasValidState() : " + (!hasValidState())

                     + " | mStatus != Status.EDITING : " + (mStatus != Status.EDITING)

                     + " , mStatus : " + mStatus);

             return false;

         }

之后添加：

//email  

   for (int n = 0; n < mState.size(); n++) {   

    RawContactDelta field =  mState.get(n);

    ArrayList<ValuesDelta> data = field.getMimeEntries("vnd.android.cursor.item/email_v2"); 

    if(data != null )

       for (int m = 0; m < data.size(); m++) {     

          String email = data.get(m).getAsString("data1");

              if (!TextUtils.isEmpty(email)) {  

                 if (!Pattern.matches(USIM_EMAIL_PATTERN, email)) {

        

                    Toast.makeText(mContext, R.string.email_invalid, Toast.LENGTH_SHORT).show();

                    getActivity().finish();

                    return false;

                }

             }      

        }

    }

KK版本
1.    SIM/USIM卡联系人：

SIMEditProcessor.java (alps\packages\apps\contacts\src\com\mediatek\contacts\simservice)

 先添加 private boolean mEmailInvalid = false;

 然后修改

  private boolean isUSIMUpdateValuesInvalid()

  //mtk add

 if (!TextUtils.isEmpty(mUpdatemail)) {

     if (!Pattern.matches(USIM_EMAIL_PATTERN, mUpdatemail)) {

           mEmailInvalid = true;

     }

 }

 //mtk add end

 LogUtils.i(TAG, "mNumberIsNull:" + mNumberIsNull + ",mNumberInvalid:" +

                 mNumberInvalid + ",mFixNumberInvalid:" + mFixNumberInvalid);  //参考位置

 
再修改

private boolean isInsertValuesInvalid()

             if (!TextUtils.isEmpty(mUpdateAdditionalNumber)) {

                 if (!Pattern.matches(SIM_NUM_PATTERN, PhoneNumberUtilsEx

                         .extractCLIRPortion(mUpdateAdditionalNumber))) {

                     mFixNumberInvalid = true;

                 }

             }//参考位置

  //mtk add

 if (!TextUtils.isEmpty(mUpdatemail)) {

     if (!Pattern.matches(USIM_EMAIL_PATTERN, mUpdatemail)) {

           mEmailInvalid = true;

     }

 }

 //mtk add end

 
最后修改

private boolean setSaveFailToastText()

         }*/ else if (mEmailInvalid) {

             mSaveFailToastStrId = R.string.cannot_insert_error_format_email;  //资源请自己添加

             mEmailInvalid = false;
