從RecyclerView適配器在BottomSheetDialogFragment內部獲取視圖

Question

我有一個RecyclerView 。 這個RecyclerView視圖的每個單元都有一個按鈕，該按鈕從Adapter內調用BottomSheetDialogFragment 。

從Adapter調用底頁時，底頁確實顯示並正確關閉

我希望能夠通過點擊BottomSheetDialogFragment的按鈕來刪除單元格。

這是我的BottomSheetDialogFragment類中的按鈕

    <Button
        android:id="@+id/deleteBtn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Delete" />

這是我的onBindViewHolder() ，在這里我找不到從BottomSheetDialogFragment訪問deleteBtn的方法，所以我可以繼續刪除單元格

override fun onBindViewHolder(holder: SavesAdapterHolder, position: Int) {
    val bottomSheet: BottomSheetDialogFragment = mBottomSheet()
    bottomSheet.setStyle(DialogFragment.STYLE_NORMAL, R.style.BottomDialogTheme)
    val myActivity = (context as FragmentActivity).supportFragmentManager
    holder.openButton.setOnClickListener {
        bottomSheet.show(myActivity, "bottomSheet $position")

    }
}

任何人都可以onBindViewHolder()向我onBindViewHolder()如何從onBindViewHolder()內部訪問刪除按鈕的正確方向

Answer 1

BottomSheet視圖應該可以通過getView（）方法訪問

override fun onBindViewHolder(holder: SavesAdapterHolder, position: Int) {
    val bottomSheet: BottomSheetDialogFragment = mBottomSheet()
    bottomSheet.setStyle(DialogFragment.STYLE_NORMAL, R.style.BottomDialogTheme)
    val myActivity = (context as FragmentActivity).supportFragmentManager
    holder.openButton.setOnClickListener {
        bottomSheet.show(myActivity, "bottomSheet $position")

       // execute the commited transaction before trying to access the view
        myActivity.executePendingTransactions()

      // accessing button view
        bottomSheet.view?.findViewById("*your_btn_id*").setOnClickListener{
             //you can remove item here and notify data set
        }

    }
}
