i'm new to android development and it would really appreciate the help

Answer 1

In Android, you cannot direct add child view inside the ListView directly. In your case, you are adding ImageView and LinearLayout as direct children of ListView . Due to this, you are getting a Runtime exception. (Ref: https://cs.android.com/android/platform/superproject/+/master:frameworks/base/core/java/android/widget/AdapterView.java;l=488 )

In Android, you are supposed to use adapter to add view inside ListView or RecyclerView . I would suggest you to look into Video tutorials instead of blog posts, since blog posts are super confusing about which code goes where.

Answer 2

只需使用 LinearLayout 而不是 ListView （我相信这是一个错字）。
