Groupie Recycler查看添加到同一可扩展项目的所有项目

Question

我正在使用 Groupie 库来显示可扩展项目，我的问题是通过 api 调用检索的项目没有显示在每个 parent 可扩展项目下 header, 它们一起显示在列表的最后一项下。

我想要这个：

• Header 1
  • Child header 1
  • Child header 1
  • Child header 1
• Header 2
  • Child header 2
  • Child header 2

我有这个：

• Header 1
• header 2
  • Child header 1
  • Child header 1
  • Child header 1
  • Child header 2
  • Child header 2

这是我的代码

 private fun updateUICurrentExercise(getCurrentWorkoutExercise: GetCurrentWorkoutExercise?) {

    adapter = GroupAdapter()
    val workouts = getCurrentWorkoutExercise?.workouts

    for (w in workouts!!) {

        exp = ExpandableGroup(WorkoutItem("Workout ${(w.workoutId)}"), false)
        getExercisesByWorkoutAPI(w.workoutId.toString())

        adapter.add(exp)
    }

    rvWorkout.adapter = adapter
}

 private fun getExercisesByWorkoutAPI(workoutId: String) {

    GetExercisesByWorkoutAPI.postData(jo, object : GetExercisesByWorkoutAPI.ThisCallback {
        override fun onSuccess(getExercisesByWorkout: GetExercisesByWorkout?) {
           
            for (e in getExercisesByWorkout?.exercises!!) {

                exp.add(Section(ExerciseItem(workoutId)))
            }
        }

    })
}

Answer 1

您似乎没有使用 Section.setHeader。因此，您需要为每个 w collection 项目创建一个 header 实例 WorkoutItem("Workout ${(w.workoutId)}"，然后将此实例传递给 ExpandableGroup 构造函数和 Section.setHeader

Answer 2

根据@valerii 的回复，问题得到解决：在同一个 api 调用中启动可扩展组及其项目。

private fun updateUICurrentExercise(getCurrentWorkoutExercise: GetCurrentWorkoutExercise?) {

    adapter = GroupAdapter()
    val workouts = getCurrentWorkoutExercise?.workouts

    for (w in workouts!!) {

        getExercisesByWorkoutAPI(w.workoutId.toString())
    }

    rvWorkout.adapter = adapter
}

 private fun getExercisesByWorkoutAPI(workoutId: String) {

    GetExercisesByWorkoutAPI.postData(jo, object : GetExercisesByWorkoutAPI.ThisCallback {
        override fun onSuccess(getExercisesByWorkout: GetExercisesByWorkout?) {

            val expandableGroup = ExpandableGroup(WorkoutItem("Workout $workoutId"), false)
            for (e in getExercisesByWorkout?.exercises!!) {
                expandableGroup.add(Section(ExerciseItem(e.exerciseName)))
            }
            adapter.add(expandableGroup)
        }
    })
}
