I got following error when i want to clear all my data in `ListAdapter`

```
 java.lang.UnsupportedOperationException
        at java.util.Collections$UnmodifiableCollection.clear(Collections.java:1116)
        at com.zhixin.wedeep.homepage.ui.AudioPlayerActivity$onComment$$inlined$apply$lambda$3$1$1.onChanged(AudioPlayerActivity.kt:300)
        at com.zhixin.wedeep.homepage.ui.AudioPlayerActivity$onComment$$inlined$apply$lambda$3$1$1.onChanged(AudioPlayerActivity.kt:60)

        at androidx.lifecycle.MutableLiveData.setValue(MutableLiveData.java:50)
        at androidx.lifecycle.LiveDataScopeImpl$emit$2.invokeSuspend(CoroutineLiveData.kt:97)

```

The error happened in this line `this.currentList.clear()`

```
  (recyclerView.adapter as CommentAdapter).apply {
                                                    this.currentList.clear()
                                                    submitList(it.data!!.items)
                                                }

```

Who has ideas for this question, Appreciated!
