如何获取联系电子邮件ID？

Question

我有手机中所有联系人姓名的列表视图.我想获取我在列表视图中单击的联系人的电子邮件ID(如果联系人有一个).我怎样才能做到这一点？

Answer 1

使用以下代码获取所有电子邮件ID.我查了一下代码.这是工作.

public static void getContactEmails(Context context) {
        String emailIdOfContact = null;
        int emailType = Email.TYPE_WORK;
        String contactName = null;


            ContentResolver cr = context.getContentResolver();
            Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
                    null, null, null);
            if (cur.getCount() > 0) {
                while (cur.moveToNext()) {
                    String id = cur.getString(cur
                            .getColumnIndex(BaseColumns._ID));
                    contactName = cur
                            .getString(cur
                                    .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    // Log.i(TAG,"....contact name....." +
                    // contactName);

                    cr.query(
                            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                            null,
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                    + " = ?", new String[] { id }, null);

                    Cursor emails = cr.query(Email.CONTENT_URI, null,
                            Email.CONTACT_ID + " = " + id, null, null);
                    while (emails.moveToNext()) {
                        emailIdOfContact = emails.getString(emails
                                .getColumnIndex(Email.DATA));
                        // Log.i(TAG,"...COntact Name ...."
                        // + contactName + "...contact Number..."
                        // + emailIdOfContact);
                        emailType = emails.getInt(emails
                                .getColumnIndex(Phone.TYPE));


                    }
                    emails.close();

                }
            }// end of contact name cursor
            cur.close();


    }

电话号码

电话号码存储在自己的表中,需要单独查询.要查询电话号码表,请使用存储在SDK变量ContactsContract.CommonDataKinds.Phone.CONTENT_URI中的URI.使用WHERE条件获取指定联系人的电话号码.

if (Integer.parseInt(cur.getString(
               cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
            Cursor pCur = cr.query(
         ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
         null, 
         ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", 
         new String[]{id}, null);
         while (pCur.moveToNext()) {
         // Do something with phones
         } 
         pCur.close();
     }

对Android联系人SQLite数据库执行第二次查询.根据ContactsContract.CommonDataKinds.Phone.CONTENT_URI中存储的URI查询电话号码.联系人ID作为ContactsContract.CommonDataKinds.Phone.CONTACT_ID存储在电话表中,WHERE子句用于限制返回的数据.

电子邮件地址

查询电子邮件地址与电话号码类似.必须执行查询才能从数据库中获取电子邮件地址.查询存储在ContactsContract.CommonDataKinds.Email.CONTENT_URI中的URI以查询电子邮件地址表

Cursor emailCur = cr.query( 
    ContactsContract.CommonDataKinds.Email.CONTENT_URI, 
    null,
    ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
    new String[]{id}, null); 
while (emailCur.moveToNext()) { 
    // This would allow you get several email addresses
        // if the email addresses were stored in an array
    String email = emailCur.getString(
                  emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
     String emailType = emailCur.getString(
                  emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE)); 
 } 
 emailCur.close();
