如何从数据库中读取联系人信息？

Question

我想读取所有的联系人信息到 PhoneBookBean 中。
PhoneBookBean 包含first_name, lastname, email_address，但是看起来很难读取 People.URL。
使用 ContactsContract，需要 mime_type，并且必须提供 lookupKey，我需要迭代所有的联系人一个一个人输入。

解决方案：

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
getContactInfo(intent);
    protected void getContactInfo(Intent intent)
    {
       Cursor cursor =  managedQuery(intent.getData(), null, null, null, null);      
       while (cursor.moveToNext()) 
       {           
           String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
           name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)); 
           String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
           if ( hasPhone.equalsIgnoreCase("1"))
               hasPhone = "true";
           else
               hasPhone = "false" ;

           if (Boolean.parseBoolean(hasPhone)) 
           {
            Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
            while (phones.moveToNext()) 
            {
                phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            }
            phones.close();
           }
           // Find Email Addresses
           Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);
           while (emails.moveToNext()) 
           {
            String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
           }
           emails.close();
        Cursor address = getContentResolver().query(
                    ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,
                    null,
                    ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID + " = " + contactId,
                    null, null);
        while (address.moveToNext()) 
        { 
          // These are all private class variables, don't forget to create them.
             String poBox      = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX));
             String street     = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
             String city       = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));
             String state      = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));
             String postalCode = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
             String country    = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY));
String  type   = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.TYPE));
        }  //address.moveToNext()   
      }  //while (cursor.moveToNext())        
       cursor.close();
    }
