Question

我正在制作拨号器，我想按姓名搜索联系人。但由于拨号器只接受数字，我应该如何输入数字5-6-4-6来搜索JOHN？在android中有没有现成的方法？

Answer 1

如果你的联系人中存在这个数字5-6-4-6，你可以使用内容uri和hpone uri查找这个数字，你可以将它与获取的结果进行比较......

您可以获取所有联系人，并通过将此数字和数字与来自andorid conatcts api的获取数字进行比较来获得名称。

public void fetchContacts() {

    String phoneNumber = null;
    String email = null;

    Uri CONTENT_URI = ContactsContract.Contacts.CONTENT_URI;
    String _ID = ContactsContract.Contacts._ID;
    String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME;
    String HAS_PHONE_NUMBER = ContactsContract.Contacts.HAS_PHONE_NUMBER;

    Uri PhoneCONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
    String Phone_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
    String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;

    Uri EmailCONTENT_URI =  ContactsContract.CommonDataKinds.Email.CONTENT_URI;
    String EmailCONTACT_ID = ContactsContract.CommonDataKinds.Email.CONTACT_ID;
    String DATA = ContactsContract.CommonDataKinds.Email.DATA;

    StringBuffer output = new StringBuffer();

    ContentResolver contentResolver = getContentResolver();

    Cursor cursor = contentResolver.query(CONTENT_URI, null,null, null, null);  

    // Loop for every contact in the phone
    if (cursor.getCount() > 0) {

        while (cursor.moveToNext()) {

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

            int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex( HAS_PHONE_NUMBER )));

            if (hasPhoneNumber > 0) {

                output.append("\n First Name:" + name);

                // Query and loop for every phone number of the contact
                Cursor phoneCursor = contentResolver.query(PhoneCONTENT_URI, null, Phone_CONTACT_ID + " = ?", new String[] { contact_id }, null);

                while (phoneCursor.moveToNext()) {
                    phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER));
                    output.append("\n Phone number:" + phoneNumber);

                }

                phoneCursor.close();

                // Query and loop for every email of the contact
                Cursor emailCursor = contentResolver.query(EmailCONTENT_URI,    null, EmailCONTACT_ID+ " = ?", new String[] { contact_id }, null);

                while (emailCursor.moveToNext()) {

                    email = emailCursor.getString(emailCursor.getColumnIndex(DATA));

                    output.append("\nEmail:" + email);

                }

                emailCursor.close();
            }

            output.append("\n");
        }

        outputText.setText(output);
    }
}

}

根据数字小键盘用字母为每个字母分配数字代码。例如将2分配给b＆amp; C 将3分配给d e＆amp; f等等。然后相应地修改您的搜索。
