Question

我正在尝试解压缩我的联系人并对其进行更改，但问题是我的构建器似乎工作正常并且没有抛出任何异常，但没有任何更改！

Cursor c;
    ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();

    Builder builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
    builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?", new String[]{String.valueOf(ContactID), ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE});
    builder.withValue(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,"blabla");
    ops.add(builder.build());

    ContentProviderResult[] res;
    try
    {
        res = getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
                        }
    catch (Exception e)
    {
        e.printStackTrace();
    }
    setListViewAdapter() ;
    c = getContentResolver().query(CommonDataKinds.Phone.CONTENT_URI, null, CommonDataKinds.Phone.CONTACT_ID +" = ?", new String[]{ContactID}, null);
    try {
           c.moveToFirst();
           displayName = c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        } 
    finally
        {
                c.close();
        }

这是我将适配器更新为联系人ListView的方法

private void setListViewAdapter() {

    // Construct the data source
    arrayOfUsers = getContactsData();


    // update the adapter to convert the array to views
    adapter.clear();
    adapter.addAll(arrayOfUsers);
    adapter.notifyDataSetChanged(); 


    // Attach the adapter to a ListView
    if (adapter!=null && lstContacts!=null)
     {
        try
        {
            lstContacts.setAdapter(adapter);
        }
        catch(Exception e) {
            System.out.println("Error! "+e.getMessage());
        }
    }
     else
        NoContacts.setVisibility(View.VISIBLE);
}

这就是我从手机通讯录目录中获取联系人信息的方式，效果很好。

private ArrayList<Contact> getContactsData() {
    String ID   = ""; 
    String name   = ""; 
    String number = ""; 

    ArrayList <Contact> mycontacts = null;
    try
    {
        //get our contact list via a Content Resolver which is the bridge between all android applications
        Uri mContacts_uri= ContactsContract.Contacts.CONTENT_URI;

        people = getContentResolver().query(mContacts_uri, // Contact URI
                                            null,    // Which columns to return
                                            null,       // Which rows to return
                                            null,       // Where clause parameters
                                            null        // Order by clause
                                            );
        int indexID = people.getColumnIndex(ContactsContract.Contacts._ID);
        int indexName = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
        int indexhasnumbers = people.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);

        mycontacts = new ArrayList<Contact>();
        Contact _person = null;
        int cur = people.getCount();
        if(cur>0)
        {
            people.moveToFirst();
            do {
            ID   = people.getString(indexID);
            name   = people.getString(indexName);

            /********************************************/
            if (Integer.parseInt(people.getString(indexhasnumbers)) > 0) 
            {
                 Cursor pCur = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
                                         null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", 
                                         new String[]{ID}, null);
                 try{

                 while (pCur.moveToNext()) {
                      int phoneType = pCur.getInt(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
                      number = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                      switch (phoneType) {
                            case ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE:
                                Log.e(name + "(mobile number)", number);
                                break;
                            case ContactsContract.CommonDataKinds.Phone.TYPE_HOME:
                                Log.e(name + "(home number)", number);
                                break;
                            case ContactsContract.CommonDataKinds.Phone.TYPE_WORK:
                                Log.e(name + "(work number)", number);
                                break;
                            case ContactsContract.CommonDataKinds.Phone.TYPE_OTHER:
                                Log.e(name + "(other number)", number);
                                break;                                  
                            default:
                                break;
                      }
                  } 
                  pCur.close();
                }
                 catch(Exception e)
                 {
                     Log.e("exception found : "+ e.getMessage()," : phone number ");
                 }
            _person=new Contact(ID,name,number);
            mycontacts.add(_person);
            }
        } 
        while (people.moveToNext());
        }

     }
    catch(Exception e) {
        System.out.println("Error! "+e.getMessage());
    }
     return mycontacts;     
}

但是显示名称仍然相同，我不明白更新功能的哪个部分无法正常工作，因为没有人抛出异常

使用此查询

String select = "((" + Contacts.DISPLAY_NAME + " NOTNULL) AND ("
                    + Contacts.HAS_PHONE_NUMBER + "=1) AND ("
                    + Contacts.DISPLAY_NAME + " != '' ))";

            Cursor c = cntx.getContentResolver().query(Contacts.CONTENT_URI, CONTACTS_SUMMARY_PROJECTION, select,
                    null, Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");

更新手机联系不起作用
