從聯繫人中獲取電子郵件和電話號碼而不擴展活動

Question

我試圖從聯繫人獲取電子郵件地址和電話號碼。我的班級沒有extend Activity，現在我被卡住了。

我該如何克服這個問題？

Answer 1

爲獲得電子郵件聯繫人

public void getEmailContacts() 
    { 
     try 
     { 
      String name; 

      ContentResolver cr = getContentResolver(); 
      cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,null, null, null); 

      emailIndex=0; 
      if (cur.getCount() > 0) 
      { 
       ArrayList<String> emailNameList=new ArrayList<String>(); 
       ArrayList<String> emailPhoneList=new ArrayList<String>(); 
       while (cur.moveToNext()) 
       { 
        String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
        name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 

        Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null, 
          ContactsContract.CommonDataKinds.Email.CONTACT_ID+ " = " + id, null, null); 
        while (emails.moveToNext()) 
        { 
         // This would allow you get several email addresses 
         String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); 
         Log.v(name+"==>", emailAddress); 
         if ((!emailAddress.equalsIgnoreCase(""))&&(emailAddress.contains("@"))) 
         { 
          emailNameList.add(name); 
          emailPhoneList.add(emailAddress); 
          emailIndex++; 
         } 
        } 
        emails.close();   
       } 

用於獲取手機中的聯繫人

String name; 

      ContentResolver cr = getContentResolver(); 

      Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,null, null, null); 

      if (cur.getCount() > 0) 
      { 
       ArrayList<String> phoneNameList=new ArrayList<String>(); 
       ArrayList<String> PhoneList=new ArrayList<String>(); 

       while (cur.moveToNext()) 
       {     
        String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
        name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
        if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) 
        { 
         phoneNameList.add(name);       
         Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
             ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = ?", new String[] { id }, null); 

         while (pCur.moveToNext()) 
         { 

          PhoneList.add(pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))); 

         } 
         pCur.close(); 
        } 
       }
