如何从数据库中读取联系人信息

Question

我只想将所有联系人信息读入PhoneBookBean。

PhoneBookBean包括名，姓，email_地址。但看起来很难看像People.URL。

使用ContactsContract，它总是需要mime_type并且必须提供lookupKey，但我只需要一个人迭代所有联系人条目。

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(); 
    }
