如何删除机器人从SIM卡联系人 [英] How to delete contacts from sim in android

问题描述

我没下code删除从SIM卡中选定的联系人。但它不是删除，也没有抛出任何错误。

 保护无效DeleteContacts（ArrayList的＆LT;串GT; IDS）{        INT FLG = 0;        的String [] = strids新的String [ids.size（）];
        strids = ids.toArray（strids）;        的for（int i = 0; I＆LT; strids.length;我++）{            光标SIMS = getActivity（）。getContentResolver（）查询（
                    Uri.parse（内容：// ICC / ADN），空，
                    _id =？，新的String [] {strids [I]}，NULL）;            sims.moveToFirst（）;
            如果（sims.getCount（）大于0）{
                字符串phoneNumber的= sims.getString（sims.getColumnIndex（数字））;
                布尔VAL = deleteContact（phoneNumber的）;
                如果（！VAL）
                    FLG = 1;
            }            如果（FLG == 0）
                Toast.makeText（getActivity（），删除联系人，Toast.LENGTH_SHORT）.show（）;
            sims.close（）;
        }
    }    公共布尔deleteContact（字符串电话）{
        光标CUR = getActivity（）getContentResolver（）查询。（Uri.parse（内容：// ICC / ADN），空？数=，新的String [] {}手机，NULL）;
        尝试{
            如果（cur.moveToFirst（））{
                做{
                    串lookupKey = cur.getString（cur.getColumnIndex（ContactsContract.Contacts.LOOKUP_KEY））;
                    URI URI = Uri.withAppendedPath（ContactsContract.Contacts.CONTENT_LOOKUP_URI，lookupKey）;
                    getActivity（）getContentResolver（）删除（URI，NULL，NULL）;
                    返回true;
                }而（cur.moveToNext（））;
            }
        }赶上（例外五）{
            的System.out.println（e.getStackTrace（））;
        }
        返回false;
    }
 

解决方案

根据 href=\"http://stackoverflow.com/a/27844393/2003986\">我的答案，这里是解决方案：

 乌里simUri = Uri.parse（内容：// ICC / ADN /）;
ContentResolver的mContentResolver = this.getContentResolver（）;
光标C = mContentResolver.query（simUri，NULL，NULL，NULL，NULL）;
如果（c.moveToFirst（））
{
    做
    {
        如果（/ *您在这里的条件* /）
        {
            mContentResolver.delete（
                simUri，
                标签='+ c.getString（c.getColumnIndex（名称））+
                '和+
                数='+ c.getString（c.getColumnIndex（数字））+'
                ， 空值）;
            打破;
        }
    }
    而（c.moveToNext（））;
}
 

当然，不要忘记这些权限：

 ＆LT;使用许可权的android：NAME =android.permission.READ_CONTACTS/＆GT;
＆LT;使用许可权的android：NAME =android.permission.WRITE_CONTACTS/＆GT;
 

I did following code for deleting selected contacts from sim card. but its not deleting and also not throwing any error.

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;
    }

解决方案

Based on my answer here, here is the solution :

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());
}

Off course, don't forget these permissions :

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