android - 将联系人图像加载到位图中

Question

我用来从电话号码中获取联系人图像缩略图 Uri 的函数。 :

public static Uri getPhotoURIFromAddress(Context activity, String address) {
    String contactId = getContactIdFromAddress(activity, address);

    ContentResolver contentResolver = activity.getContentResolver();
    try {
        Cursor cursor = contentResolver
                .query(ContactsContract.Data.CONTENT_URI,
                        null,
                        ContactsContract.Data.CONTACT_ID
                                + "="
                                + contactId
                                + " AND "

                                + ContactsContract.Data.MIMETYPE
                                + "='"
                                + ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE
                                + "'", null, null);

        if (cursor != null) {
            if (!cursor.moveToFirst()) {
                return null; // no photo
            }
        } else {
            return null; // error in cursor process
        }
        cursor.close();

    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }

    Uri person = ContentUris.withAppendedId(
            ContactsContract.Contacts.CONTENT_URI, Long.valueOf(contactId));
    return Uri.withAppendedPath(person,
            ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}

这将以以下形式返回一个 Uri:

content://com.android.contacts/contacts/799/photo

现在，如果我在带有 setImageUri(Uri) 函数的 ImageView 中使用这个 Uri，它就可以工作。

但是加载一个Bitmap是个问题。我正在使用的功能是:

public static Bitmap getContactBitmapFromURI(Context context, Uri uri) {
        InputStream input = ContactsContract.Contacts
                .openContactPhotoInputStream(context.getContentResolver(), uri);
        if (input == null) {
            return null;
        }
        return BitmapFactory.decodeStream(input);
    }

总是崩溃。 LogCat 是:

请帮忙!

Answer 1

我认为您不应该将照片的 uri 传递给 openContactphotoinputstream。您只需要传递联系人本身的 uri 即可获取位图。

 Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
  InputStream stream = ContactsContract.Contacts.openContactPhotoInputStream(
            mContext.getContentResolver(), uri);

或者，如果您要传递联系人照片 uri，那么您可以使用

public static Bitmap getContactBitmapFromURI(Context context, Uri uri) {
        InputStream input = context.getContentResolver().openInputStream(uri)
        if (input == null) {
            return null;
        }
        return BitmapFactory.decodeStream(input);
    }
