Android:插入后获取联系人ID [英] Android: get contact id after insert

问题描述

我需要在创建新联系人后存储联系人ID值，以便能够在其他时候引用它.例如，我创建一个新联系人，此后我要从其联系人ID中删除它，因此在创建新联系人之后，我需要检索联系人ID值.这是我创建新联系人的方式:

I need to store the contact id value after create a new contact, in order to be able to reference it in other moment. For example, I create a new contact, and after that I want to delete it from its contact id, so I need to retrieve the contact id value after create a new contact. This is how I create new contacts:

ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
    ops.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI).withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, tipoCuenta).withValue(ContactsContract.RawContacts.ACCOUNT_NAME, cuenta).build());

//Insert some data here....

c.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

//Here, I want to retrieve contact id

我该怎么做?

推荐答案

The ContentResolver.applyBatch() method returns an array of ContentProviderResult objects, one for each operation. Each of these has the uri of the inserted contact (in the format content://com.android.contacts/raw_contacts/<contact_id>).

因此要获取联系人的ID，您只需解析此uri，即

So to get the contact's id you just have to parse this uri, i.e.

ContentProviderResult[] results = getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
int contactId = Integer.parseInt(results[0].uri.getLastPathSegment());
