Question

我能够获取所有联系人并将其显示在列表视图中。我也得到了联系人的照片。我的问题是，如果联系人没有照片，我的列表视图不会显示任何内容（空格）。我试图检查某些地方，如果ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI有照片或没有，但我找不到某种方法。

在简历中，我想要的是，如果联系人有照片显示照片，如果没有，则显示一个图标。

任何帮助都是合情合理的！

代码：

private final static String[] FROM_COLUMNS = {
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
            ContactsContract.CommonDataKinds.Phone.NUMBER,
            ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI
    };
    private final static int[] TO_IDS = {
            R.id.contactName,
            R.id.message_subtitle,
            R.id.contact_imageview
    };
    private static final String[] PROJECTION = {
            ContactsContract.CommonDataKinds.Phone._ID,
            ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
            ContactsContract.CommonDataKinds.Phone.NUMBER,
            ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI
    };

    private static final String SELECTION = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " LIKE ?";
    private String[] mSelectionArgs = {"%%"};

    private ListView mContactsList;
    private SimpleCursorAdapter mCursorAdapter;

    public contacts() {
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.contacts_list_fragment, container, false);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        mContactsList = (ListView) getActivity().findViewById(R.id.contacts_list);
        mCursorAdapter = new SimpleCursorAdapter(getActivity(), R.layout.list_item, null, FROM_COLUMNS, TO_IDS, 0);
        mContactsList.setOnItemClickListener(this);
        mContactsList.setAdapter(mCursorAdapter);
        getLoaderManager().initLoader(0, null, this);
    }

    @Override
    public Loader<Cursor> onCreateLoader(int id, Bundle args) {
        return new CursorLoader(getActivity(), ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION, SELECTION, mSelectionArgs,
                ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");
    }

试试这个：

更改

ContactsContract.CommonDataKinds.Phone.

到

ContactsContract.Contacts.

你的onCreateLoader中的

：

return new CursorLoader(getActivity(), baseUri, PROJECTION, select, null, ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");

在适配器中：

 @Override
        public void bindView(View view, Context context, Cursor cursor) {

            ImageView imageView = (ImageView) view.findViewById(R.id.contact_imageview);
            Bitmap profileImage = getPhoto(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)));


            if(profileImage !=null) {
                imageView.setImageBitmap(profileImage);
            }else{
                imageView.setImageDrawable(getResources().getDrawable(R.drawable.ic_contact));
            }
        }

        private Bitmap getPhoto(String id){

            Bitmap photo = null;
            try{
                InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(
                        getActivity().getContentResolver(),
                        ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI , new Long(id).longValue()));
                if(inputStream != null)
                    photo= BitmapFactory.decodeStream(inputStream);
            }catch (Exception e){

            }
            return photo;
        }
    }
