获取联系人头像

推荐安卓开发神器（里面有各种UI特效和android代码库实例）

ContentResolver cr = getContentResolver();
    Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
        "DISPLAY_NAME = '" + NAME + "'", null, null);
    if (cursor.moveToFirst()) {
        String contactId =
            cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
        //
        // Get the contact photo.
        //
        Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI,
            Long.parseLong(contactId));
        InputStream input =
            ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
        Bitmap contactPhoto = BitmapFactory.decodeStream(input);
