Question

在这个主题中我已经看了很多主题，但是我无法在自己的代码中修改代码。因为显然有一个我看不到的错误。而且我得到了错误。

EpisodeModel.class

公共类EpisodeModel {

>>> dates
array([19700101., 19700102., 19700103., 19700104., 19700105., 19700106.,
       19700107., 19700108., 19700109., 19700110., 19700111., 19700112.,
       19700113., 19700114.])
>>> y, m, d = dates.astype(int) // np.c_[[10000, 100, 1]] % np.c_[[10000, 100, 100]]
>>> y.astype('U4').astype('M8') + (m-1).astype('m8[M]') + (d-1).astype('m8[D]')
array(['1970-01-01', '1970-01-02', '1970-01-03', '1970-01-04',

Answer 1

EpisodeModel EpisodeModel = dataSnapshot.getValue（EpisodeModel.class）;

在此行中，您得到错误消息，表明布尔对象无法转换为EpisodeModel。如果您已将该子项的值设置为 true 或 false （不带双引号），则可能会出现此消息。再次看到它，并尝试在要设置为子值的“ true” 或“ false” 周围添加双引号。

无法转换类型为java.lang.Boolean的对象
