從聯系人列表中獲取電話號碼

Question

我需要從聯系人那里獲取聯系電話

我使用以下代碼在onCreate中獲取聯系電話：

 buttonSelectContact.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
            startActivityForResult(intent, PICK_CONTACT);

        }
    });

並在onAcivityResult中使用以下代碼：

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

     Uri contactData = data.getData();
            Cursor c = managedQuery(contactData, null, null, null, null);
            if (c.moveToFirst()) {
                String name = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
                String number = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.HAS_PHONE_NUMBER));
                etName.setText(name);
                etNumber.setText(number);
}

etName設置正確，但是etNumber錯誤，里面的值是0還是1如何在etNumber中設置聯系人號碼？

這是我在onActivityResult中的方法，它從一個片段中獲取聯系人的所有電話號碼，因此如果您從活動中進行操作，則必須取出getActivity（）

Uri contactData = data.getData();
            Cursor c = getActivity().getContentResolver().query(contactData, null, null, null, null);
            if (c.moveToFirst()) {
                String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                textcontact.setText(name + "\n");
                customerName = name;
                String contactId = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
                String hasNumber = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
                String num = "";
                if (Integer.valueOf(hasNumber) == 1) {
                    Cursor numbers = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null);
                    while (numbers.moveToNext()) {
                        num = numbers.getString(numbers.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                       textcontact.append(num + "\n");
                       phoneNumbers.add(num);
                    }
                }
            }
