Контактное задание занимает слишком много времени

Question

В моем коде для извлечения контактов требуется слишком много времени для извлечения контактов и отображения в приложении. Пожалуйста, направляйте меня, где я ошибаюсь, и что я должен исправить, чтобы быстро выполнить время выполнения.

Вот мой код.

ContentResolver cr = getContentResolver(); 
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, 
      null, null, null); 
    String phone = null; 
    List<String> phonenumber = new ArrayList<String>(); 
    String emailContact = null; 
    String emailType = null; 
    String image_uri = ""; 
    Bitmap bitmap = null; 
    if (cur.getCount() > 0) { 
     while (cur.moveToNext()) 
     { 
      String id = cur.getString(cur 
        .getColumnIndex(ContactsContract.Contacts._ID)); 
      String name = cur 
        .getString(cur 
          .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 

      image_uri = cur 
        .getString(cur 
          .getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI)); 
      if (Integer 
        .parseInt(cur.getString(cur 
          .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) 
      { 
       System.out.println("name : " + name + ", ID : " + id); 

       Cursor pCur = cr.query(
         ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
         null, 
         ContactsContract.CommonDataKinds.Phone.CONTACT_ID 
           + " = ?", new String[]{id}, null); 
       Log.e("pCur","dfgfdg "+pCur.getCount()); 
       while (pCur.moveToNext()) 
       { 
         phone = pCur 
           .getString(pCur 
             .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
        // contactid=pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 

        /* phonenumber.add(pCur 
          .getString(pCur 
            .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));`*/ 
        Log.e("phone" ,phone); 

       } 
       pCur.close(); 


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

       while (emailCur.moveToNext()) 
       { 
        emailContact = emailCur 
          .getString(emailCur 
            .getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); 

        if(TextUtils.isEmpty(emailContact)||emailContact.equalsIgnoreCase(null)||emailContact.equalsIgnoreCase("")) 
        { 
         emailContact=""; 

         Log.e("isEmpty","isEmpty " + emailContact); 
        } 

        else 
        { 
         Log.e("gfdszfg","Email " + emailContact); 
        } 
        /* emailType = emailCur 
          .getString(emailCur 
            .getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));*/ 

        Log.e("gfdszfg","Email " + emailContact); 
       } 
       emailCur.close(); 
      } 

      if (image_uri != null) 
      { 
       System.out.println(Uri.parse(image_uri)); 
       try 
       { 
        bitmap = MediaStore.Images.Media 
          .getBitmap(this.getContentResolver(), 
            Uri.parse(image_uri)); 
        System.out.println(bitmap); 

       } catch (FileNotFoundException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } catch (IOException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
      } 

      mList.add(new Contacts(name, phone, image_uri,emailContact)); 
      emailContact=""; 
     } 
     cur.close(); 
     mMyContactsAdapter = new MyContactsAdapter(MainActivity.this, mList); 
     mcontact.setAdapter(mMyContactsAdapter); 
    } 

и более того, в моем коде мой контакт выборки в то время как цикл цикл 3 раза я не знаю, почему.

Answer 1

Я столкнулся с такой ситуацией, как сейчас. Попробуйте ниже код

public static ArrayList ReadContactsSpecialWay(Context context) { 
    StringBuffer contactBuffer = new StringBuffer(); 
    StringBuffer emailBuffer = new StringBuffer(); 

    ArrayList<String> contactList = new ArrayList<>(); 
    ArrayList<String> emailList = new ArrayList<>(); 
    ArrayList<ContactModel> contactModelsList = new ArrayList<>(); 
    HashMap<Integer, Boolean> hashMap = new HashMap<Integer, Boolean>(); 
    String[] emailsAndContacts = new String[2]; 

    // Phone numbers 
    Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; 
    String[] projection = new String[]{ 
      ContactsContract.CommonDataKinds.Phone.CONTACT_ID, 
      ContactsContract.Contacts.DISPLAY_NAME, 
      ContactsContract.CommonDataKinds.Phone.NUMBER 
    }; 

    Cursor phoneNumbers = context.getContentResolver().query(uri, projection, null, null, null); 
    int indexContactID = phoneNumbers.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID); 
    int indexName = phoneNumbers.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME); 
    int indexNumber = phoneNumbers.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); 
    while (phoneNumbers.moveToNext()) { 
     Integer contactId = phoneNumbers.getInt(indexContactID); 
     String contactName = phoneNumbers.getString(indexName); 
     String contactNumber = phoneNumbers.getString(indexNumber).replace(" ", ""); 

     ContactModel contactModel = new ContactModel(); 
     contactModel.setContactPhone(contactNumber); 
     contactNumber = contactModel.getContactPhone(); 

     if (hashMap.containsKey(contactId)) 
      contactModel.setContactName(contactName + " (" + contactNumber + ")"); 
     else { 
      hashMap.put(contactId, true); 
      contactModel.setContactName(contactName); 
     } 
     contactModelsList.add(contactModel); 
     contactList.add(contactNumber); 
     LogHelper.informationLog(contactNumber + " " + contactName); 
     contactBuffer.append(contactNumber + ","); 
    } 
    phoneNumbers.close(); 

    // Emails 
    uri = ContactsContract.CommonDataKinds.Email.CONTENT_URI; 
    projection = new String[]{ 
      ContactsContract.CommonDataKinds.Email.CONTACT_ID, 
      ContactsContract.Contacts.DISPLAY_NAME, 
      ContactsContract.CommonDataKinds.Email.DATA 
    }; 
    Cursor emails = context.getContentResolver().query(uri, projection, null, null, null); 
    indexContactID = emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID); 
    indexName = emails.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME); 
    int indexData = emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA); 
    while (emails.moveToNext()) { 
     Integer contactId = emails.getInt(indexContactID); 
     String contactName = emails.getString(indexName); 
     String contactEmail = emails.getString(indexData).toLowerCase(); 
     ContactModel contactModel = new ContactModel(); 
     contactModel.setEmailAddress(contactEmail); 

     if (hashMap.containsKey(contactId)) { 
      contactModel.setEmailName(contactName + " (" + contactEmail + ")"); 
     } else { 
      contactModel.setEmailName(contactName); 
      hashMap.put(contactId, true); 
     } 
     contactModelsList.add(contactModel); 

     if (contactEmail != null && !emailList.contains(contactEmail)) { 
      emailList.add(contactEmail); 
      LogHelper.informationLog(contactEmail + " " + contactName); 
      emailBuffer.append(contactEmail + ","); 
     } 
    } 
    emails.close(); 

    if (contactBuffer.toString().length() > 0) { 
     emailsAndContacts[0] = contactBuffer.toString().substring(0, (contactBuffer.toString().length() - 1)); 
    } else 
     emailsAndContacts[0] = ""; 

    if (emailBuffer.toString().length() > 0) { 
     emailsAndContacts[1] = emailBuffer.toString(); 
    } else { 
     emailsAndContacts[1] = ""; 
    } 

    if(contactModelsList.size() == 0) 
     return null; 
    else { 
     ArrayList specialList = new ArrayList(); 
     specialList.add(contactModelsList); 
     specialList.add(emailsAndContacts); 

     return specialList; 
    } 
} 

Это определенно поможет вам.

Попробуйте это, используя AsyncTask. Используйте его во время запуска активности по умолчанию для приложений по умолчанию и извлеките массив при использовании в другом действии.

class LoadContact extends AsyncTask<Void, Void, Void> { 
    @Override 

    protected void onPreExecute() { 
     super.onPreExecute(); 
    } 

    @Override 
    protected Void doInBackground(Void... voids) { 
     // Get Contact list from Phone 

     Uri CONTENT_URI = ContactsContract.Contacts.CONTENT_URI; 

     String _ID = ContactsContract.Contacts._ID; 

     String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME; 
     Uri PhoneCONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; 

     String Phone_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID; 

     String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER; 

     ContentResolver contentResolver = getContentResolver(); 

     /** 
     * @discussion Query contact and return name and contact Id. 
     */ 
     Cursor cursor = contentResolver.query(CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC"); 

     if (cursor.getCount() > 0) { 
      while (cursor.moveToNext()) { 
       Bitmap bit_thumb = null; 

       String contact_id = cursor.getString(cursor.getColumnIndex(_ID)); 
       String name = cursor.getString(cursor.getColumnIndex(DISPLAY_NAME)); 

       String image_thumb = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI)); 
       Cursor phoneCursor = contentResolver.query(PhoneCONTENT_URI, null, Phone_CONTACT_ID + " = ?", new String[]{contact_id}, null); 
       try { 
        if (image_thumb != null) { 
         bit_thumb = MediaStore.Images.Media.getBitmap(contentResolver, Uri.parse(image_thumb)); 
        } 
       } catch (IOException e) { 
        e.printStackTrace(); 
       } 


       while (phoneCursor.moveToNext()) { 
        String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER)); 

        final SelectUser selectUser = new SelectUser(); 
        selectUser.setName(name); 
        selectUser.setContactId(contact_id + "" + phoneNumber); 
        selectUser.setThumb(bit_thumb); 
        selectUser.setPhone(phoneNumber); 
        if (selectUser.getPhone() != null && selectUser.getPhone().length() > 0 && !num.equalsIgnoreCase(phoneNumber)) { 
         num = phoneNumber; 
         selectUsers.add(selectUser); 
        } 
       } 
       phoneCursor.close(); 
       Cursor cur1 = contentResolver.query(
         ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, 
         ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
         new String[]{contact_id}, null); 
       while (cur1.moveToNext()) { 
        String email = cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); 
        final SelectUser selectUser = new SelectUser(); 
        selectUser.setName(name); 
        selectUser.setContactId(contact_id + "" + email); 
        selectUser.setThumb(bit_thumb); 
        selectUser.setEmail(email); 
        if (selectUser.getEmail() != null && selectUser.getEmail().length() > 0 && !userEmail.equalsIgnoreCase(email)) { 
         userEmail=email; 
         selectUsers.add(selectUser); 
        } 
       } 
       cur1.close(); 


      } 
     } 
     cursor.close(); 
     return null; 
    } 

    @Override 
    protected void onPostExecute(Void aVoid) { 
     super.onPostExecute(aVoid); 
     isContactLoaded = true; 

    } 
}
