Android-更新联系人

Question

我正在尝试直接从我的应用程序更新我的电话簿的联系人。我可以添加和删除联系人，但是更新什么也没做！

在插入之后或当我抓住联系人时，我将收集CONTACT_ID（又称_ID）。

这是我的更新代码：

public void update(Relation r)
{
    Log.e("", ""+r.getBook_id());
    ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();

    Builder builder = ContentProviderOperation.newUpdate(ContactsContract.RawContacts.CONTENT_URI);
    builder.withValue(RawContacts.ACCOUNT_TYPE, null);
    builder.withValue(RawContacts.ACCOUNT_NAME, null);
    ops.add(builder.build());

    // Name
    builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
    builder.withSelection(ContactsContract.Data._ID,  new String[]{String.valueOf(r.getBook_id())});
    builder.withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE);
    builder.withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME, r.getFirstName()+ " " +r.getLastName());
    ops.add(builder.build());

    // Number
    builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
    builder.withSelection(ContactsContract.Data._ID,  new String[]{String.valueOf(r.getBook_id())});
    builder.withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
    builder.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, r.getNumber());
    builder.withValue(ContactsContract.CommonDataKinds.Phone.TYPE, ContactsContract.CommonDataKinds.Phone.TYPE_WORK);
    ops.add(builder.build());

    // Picture
    try
    {
        Bitmap bitmap = MediaStore.Images.Media.getBitmap(context.getContentResolver(), Uri.parse(r.getPhoto()));
        ByteArrayOutputStream image = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG , 100, image);
        builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
        builder.withSelection(ContactsContract.Data._ID,  new String[]{String.valueOf(r.getBook_id())});
        builder.withValue(ContactsContract.Data.MIMETYPE,ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE);
        builder.withValue(ContactsContract.CommonDataKinds.Photo.PHOTO, image.toByteArray());
        ops.add(builder.build());
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

    // Update
    try
    {
        context.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

r.getBook_id()给我当前联系人的_ID值。 r.getFirstName()并r.getLastName()给我联系人的名字。
r.getPhoto()给我他的照片uri。最后r.getNumber()给我他的电话号码。

Log行为我提供了正确的_ID值，我认为问题不出在这里。我做错什么了吗？

谢谢。

问候。

Answer 1

最后，我发现了如何更新联系人，这是update方法的代码：

    public void update()
    {       
        int id = 1;
        String firstname = "Contact's first name";
        String lastname = "Last name";
        String number = "000 000 000";
        String photo_uri = "android.resource://com.my.package/drawable/default_photo";

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

        // Name
        Builder builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
        builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE});
        builder.withValue(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME, lastname);
        builder.withValue(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME, firstname);
        ops.add(builder.build());

        // Number
        builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
        builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?"+ " AND " + ContactsContract.CommonDataKinds.Organization.TYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE, String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_HOME)});
        builder.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, number);
        ops.add(builder.build());


        // Picture
        try
        {
            Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), Uri.parse(photo_uri));
            ByteArrayOutputStream image = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG , 100, image);

            builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
            builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE});
            builder.withValue(ContactsContract.CommonDataKinds.Photo.PHOTO, image.toByteArray());
            ops.add(builder.build());
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }

        // Update
        try
        {
            getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }

该字段id是将新联系人插入数据库时​​返回的原始联系人ID。这是获取此ID的代码：

    ContentProviderResult[] res;
    try
    {
        res = KramerApplication.getInstance().getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
        if (res != null && res[0] != null)
        {
            String uri = res[0].uri.getPath().substring(14);
            r.setBook_id( new Integer(uri).intValue() );
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
