android - 如何删除android中的sim卡联系人

Question

下面是我从手机中删除联系人的代码

Uri contactUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,
                Uri.encode(phone));
        Cursor cur = mContext.getContentResolver().query(contactUri, null,
                null, null, null);
        boolean flag = false;
        try {
            if (cur.moveToFirst()) {
                do {
                    if (cur.getString(
                            cur.getColumnIndex(PhoneLookup.DISPLAY_NAME))
                            .equalsIgnoreCase(name)) {
                        String lookupKey = cur
                                .getString(cur
                                        .getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
                        Uri uri = Uri.withAppendedPath(
                                ContactsContract.Contacts.CONTENT_LOOKUP_URI,
                                lookupKey);
                        mContext.getContentResolver().delete(uri, null, null);
                        flag=true;
                        break;
                    }

                } while (cur.moveToNext());
            }

        } catch (Exception e) {
            flag=false;
            System.out.println(e.getStackTrace());
        }

从手机中删除联系人工作正常，但 sim 联系人删除临时意味着当我的手机重新启动时，我的联系人恢复了我删除的内容。帮助找到解决这个问题的方法。谢谢...

Answer 1

您要使用的 URI 是这个:content://icc/adn/

此外，您必须使用姓名和号码才能删除联系人。

尝试这样的事情(对我有用):

Uri simUri = Uri.parse("content://icc/adn/");
ContentResolver mContentResolver = this.getContentResolver();
Cursor c = mContentResolver.query(simUri, null, null, null, null);
if (c.moveToFirst())
{
    do
    {
        if (/* your condition here */)
        {
            mContentResolver.delete(
                simUri,
                "tag='" + c.getString(c.getColumnIndex("name")) +
                "' AND " +
                "number='" + c.getString(c.getColumnIndex("number")) + "'"
                , null);
            break;
        }                       
    }
    while (c.moveToNext());
}

当然，不要忘记这些权限:

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
