android - 如何从android中的sim中删除联系人

Question

我做了以下代码，用于从 SIM 卡中删除选定的联系人。但它不会删除，也不会抛出任何错误。

protected void DeleteContacts(ArrayList<String> ids){

        int flg = 0;

        String[] strids = new String[ids.size()];
        strids = ids.toArray(strids);

        for (int i = 0; i < strids.length; i++) {

            Cursor sims = getActivity().getContentResolver().query(
                    Uri.parse("content://icc/adn"), null,
                    "_id=?", new String[]{strids[i]}, null);

            sims.moveToFirst();
            if (sims.getCount()>0) {
                String phoneNumber = sims.getString(sims.getColumnIndex("number"));
                boolean val = deleteContact(phoneNumber);
                if (!val)
                    flg=1;
            }

            if (flg == 0)
                Toast.makeText(getActivity(), "Contact Deleted", Toast.LENGTH_SHORT).show();
            sims.close();
        }
    }

    public boolean deleteContact(String phone) {
        Cursor cur = getActivity().getContentResolver().query(Uri.parse("content://icc/adn"), null, "number=?", new String[] { phone }, null);
        try {
            if (cur.moveToFirst()) {
                do {
                    String lookupKey = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
                    Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
                    getActivity().getContentResolver().delete(uri, null, null);
                    return true;
                } while (cur.moveToNext());
            }
        } catch (Exception e) {
            System.out.println(e.getStackTrace());
        }
        return false;
    }

您正在从 sqlite 数据库而不是 SIM 卡中删除联系人。要从 SIM 卡中删除联系人，您只需删除 Uri.parse("content://icc/adn") uri。但要删除，您需要同时提供姓名和号码。名称列必须指定为标签。在此处检查删除方法 https://android.googlesource.com/platform/frameworks/opt/telephony/+/9ebea45a36838f0547a9c30f7cd9c60b03aab3b4/src/java/com/android/internal/telephony/IccProvider.java
