Answer 1

public static Bitmap retrieveContactPhoto(Context context, String number) {
        ContentResolver contentResolver = context.getContentResolver();
        String contactId = null;
        Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));

        String[] projection = new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME, ContactsContract.PhoneLookup._ID};

        Cursor cursor =
                contentResolver.query(
                        uri,
                        projection,
                        null,
                        null,
                        null);

        if (cursor != null) {
            while (cursor.moveToNext()) {
                contactId = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.PhoneLookup._ID));
            }
            cursor.close();
        }

        Bitmap photo = BitmapFactory.decodeResource(context.getResources(),
                R.drawable.default_image);

        try {
            InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(context.getContentResolver(),
                    ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(contactId)));

            if (inputStream != null) {
                photo = BitmapFactory.decodeStream(inputStream);
            }

            assert inputStream != null;
            inputStream.close();

        } catch (IOException e) {
            e.printStackTrace();
        }
        return photo;
    }

我认为这个版本在所有 android 版本中效果更好：

public   Bitmap getContactsDetails(String address) {
    Bitmap bp = BitmapFactory.decodeResource(context.getResources(),
            R.drawable.contact_default_picture);





    Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(address));

    // querying contact data store
    Cursor phones = context.getContentResolver().query(contactUri, null, null, null, null);


    while (phones.moveToNext()) {
        String image_uri = phones.getString(phones.getColumnIndex(
                ContactsContract.CommonDataKinds.Phone.PHOTO_URI));

        if (image_uri != null) {

            try {
                bp = MediaStore.Images.Media
                        .getBitmap(context.getContentResolver(),
                                Uri.parse(image_uri));

            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }

    return   bp;

}
