我有一个 if 语句写在下面:
//Set Friend Action OnClickListener & Image
if (ParseUser.getCurrentUser().getList("friendsArray").contains(searchResultsList.get(position))) {
Glide.with(holder.imgFriendAction.getContext()).load(R.drawable.ic_phone_black_24dp).into(holder.imgFriendAction);
ImageViewCompat.setImageTintList(holder.imgFriendAction, ColorStateList.valueOf(searchContext.getColor(R.color.green)));
}
else if (ParseUser.getCurrentUser().getList("pendingFriendsArray").contains(searchResultsList.get(position))) {
Glide.with(holder.imgFriendAction.getContext()).load(R.drawable.ic_check_black_24dp).into(holder.imgFriendAction);
ImageViewCompat.setImageTintList(holder.imgFriendAction, ColorStateList.valueOf(searchContext.getColor(R.color.gray_dark)));
}
else {
Glide.with(holder.imgFriendAction.getContext()).load(R.drawable.ic_person_add_black_24dp).into(holder.imgFriendAction);
ImageViewCompat.setImageTintList(holder.imgFriendAction, ColorStateList.valueOf(searchContext.getColor(R.color.colorPrimary)));
}
问题是,每次我运行该语句时,它总是为两个 if 语句返回 FALSE,即使我知道 'friendsArray' 和 'pendingFriendsArray' 在许多情况下返回 TRUE 的事实。
两个数组都包含指向 _User 表的指针。
searchResultsList 声明如下:
private List<ParseUser> searchResultsList;
我已将所有三个项目(friendsArray、pendingFriendsArray 和 searchResultsList.get(position))记录到控制台,它们显示以下内容:
D/friendsArray: [com.parse.ParseUser@ae66779, com.parse.ParseUser@8371cbe, com.parse.ParseUser@32d511f, com.parse.ParseUser@5fd2c6c, com.parse.ParseUser@7dd0235, com.parse.ParseUser@9c446ca, com.parse.ParseUser@5fe03b]
D/pendingFriendsArray: [com.parse.ParseUser@7c6a358, com.parse.ParseUser@3688cb1, com.parse.ParseUser@480596]
D/searchResultsList.get(position) =: com.parse.ParseUser@5fe03b
整个班级如下:
