Question

创建一个应用程序，我在其中使用内容提供程序在recyclerview中获取所有设备联系人。我的所有联系人和联系人姓名即将开始，但联系人图片未显示。

我的图片为空，但图片是在我的设备联系人上设置的。这就是我所做的。

private void getAllContacts() {

    ContentResolver contentResolver = getActivity().getContentResolver();
    Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
    if (cursor.getCount() > 0) {
        while (cursor.moveToNext()) {

            int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));
            if (hasPhoneNumber > 0) {
                String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                String image_uri = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_URI));


                contactVO = new Contact();
                contactVO.setContactImage(image_uri);
                contactVO.setContactName(name);

                /*if (image_uri != null) {
                    image.setImageURI(Uri.parse(image_uri));
                }*/

                phoneCursor = contentResolver.query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                        null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                        new String[]{id},
                        null);

                if (phoneCursor.moveToNext()) {
                    phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                      contactVO.setContactNumber(phoneNumber);

                    if (Objects.equals(phoneNumber, mobile)) {
                        contactArrayList.add(contact);
                    }
                }

                phoneCursor.close();
            //object of model class
            contactArrayList.add(contactVO);

            }
}

Answer 1

如果您有contactID，则可以通过将联系人ID添加到联系人Contacts.Photo.CONTENT_DIRECTORY轻松获取联系人图片

 private Uri retrieveContactPhoto(String id) {

    return Uri.withAppendedPath(ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long.parseLong(id)),
            ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}

然后使用Glide的{{1}}将联系人图片加载到imageview

你可以试试这个：联系人由getId（）标识：

/**
 * @return the photo URI
 */
public Uri getPhotoUri() {
    try {
        Cursor cur = this.ctx.getContentResolver().query(
                ContactsContract.Data.CONTENT_URI,
                null,
                ContactsContract.Data.CONTACT_ID + "=" + this.getId() + " AND "
                        + ContactsContract.Data.MIMETYPE + "='"
                        + ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE + "'", null,
                null);
        if (cur != null) {
            if (!cur.moveToFirst()) {
                return null; // no photo
            }
        } else {
            return null; // error in cursor process
        }
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
    Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long
            .parseLong(getId()));
    return Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}

用法是：

Uri u = objItem.getPhotoUri();
if (u != null) {
        mPhotoView.setImageURI(u);
} else {
        mPhotoView.setImageResource(R.drawable.ic_contact_picture_2);
}

希望这会对你有所帮助。
