Add/Replace Fragment inside of BottomSheetDialogFragment

Question

This this code : in which i open bottomSheetDialogFragment in that i want to add fragment.

I want to add multiple fragments in bottomsheetDialogFragment but it throws

java.lang.IllegalArgumentException: No view found for id 0x7f0a01cb

class AddNotesBottomSheetDialog : BottomSheetDialogFragment() {

private lateinit var bottomSheetDialog: BottomSheetDialog
private lateinit var bottomSheetBehavior: BottomSheetBehavior<View>

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    Log.v(LOG_TAG, "-> onCreateDialog")

    bottomSheetDialog = BottomSheetDialog(context!!)

    var view = View.inflate(context, R.layout.bottom_sheet_notes, null)
    bindViews(view)
    bottomSheetDialog.setContentView(view)
    bottomSheetBehavior = BottomSheetBehavior.from(view.parent as View)
    bottomSheetBehavior.isHideable = false
    bottomSheetBehavior.state = BottomSheetBehavior.STATE_EXPANDED

    return bottomSheetDialog
}

private fun bindViews(view: View) {
    loadAddNotesFragments()

}

override fun onStart() {
    super.onStart()
    Log.v(LOG_TAG, "-> onStart")

    bottomSheetBehavior.isHideable = false
    bottomSheetBehavior.state = BottomSheetBehavior.STATE_EXPANDED
    if (!visible)
        dialog.hide()
}


fun show(fragmentManager: FragmentManager) {
    Log.v(LOG_TAG, "-> show")

    visible = true
    if (isAdded) {
        Log.v(LOG_TAG, "-> Is already added")
        dialog.show()
    } else {
        Log.v(LOG_TAG, "-> Not added")
        show(fragmentManager, AddNotesBottomSheetDialog.LOG_TAG)
    }
}

override fun onDestroyView() {
    super.onDestroyView()
    Log.v(LOG_TAG, "-> onDestroyView")
}

private fun loadAddNotesFragments() {

    val createNoteFragment = CreateNoteFragment()
    val ft = fragmentManager?.beginTransaction()
    ft?.replace(R.id.placeHolderBottomSheet, createNoteFragment)
    ft?.commit()
}
}

Solved: I tried to add multiple fragments transaction in bottomSheetDialogFragment but it's not possible to do transaction in BottomSheetDialogFragment thats why its through this exception. so i used viewPager inside the BottomsheetDialog and its work perfect.

Inside a `Fragment`, `fragmentManager` is the hosting `Activity`'s `FragmentManager`. You need to use the child `FragmentManager` to transact `Fragment`s inside another. — Mike M., Dec 17 '18 at 07:10
Call `loadAddNotesFragments()` after `setContentView()` inside your **onCreateDialog** method. — Jeel Vankhede, Dec 17 '18 at 07:13
This is a fragment inside another fragment so,you need to use getChildFragmentManager(). Have a look at: https://stackoverflow.com/questions/6672066/fragment-inside-fragment — Sinan Ceylan, Mar 16 '19 at 18:23
i needed to add fragments inside bottomsheetDialogFrament so this is not working but i used viewpager using getChildFragmentManager() and its working now..Thank you..@Sinan Ceylan for the idea :) — khushbu, Mar 28 '19 at 09:19

try calling loadAddNotesFragments() in

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
     loadAddNotesFragments()
}

And try using childFragmentManager to begin transaction's: reference

private fun loadAddNotesFragments() {

    val createNoteFragment = CreateNoteFragment()
    val ft = childFragmentManager()?.beginTransaction()
    ft?.replace(R.id.placeHolderBottomSheet, createNoteFragment)
    ft?.commit()
}

I believe this will solve your problem.

UPDATE:

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        return inflater.inflate(R.layout.bottom_sheet_notes, container, false)
    }

use this to inflate the content of bottomSheet, and

REMOVE:

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    Log.v(LOG_TAG, "-> onCreateDialog")

    bottomSheetDialog = BottomSheetDialog(context!!)

    var view = View.inflate(context, R.layout.bottom_sheet_notes, null)
    bindViews(view)
    bottomSheetDialog.setContentView(view)
    bottomSheetBehavior = BottomSheetBehavior.from(view.parent as View)
    bottomSheetBehavior.isHideable = false
    bottomSheetBehavior.state = BottomSheetBehavior.STATE_EXPANDED

    return bottomSheetDialog
}

ADD:

 override fun onStart() {
        super.onStart()
        val bottomSheet = dialog.findViewById(android.support.design.R.id.design_bottom_sheet) as ViewGroup   //FrameLayout as my 
        val mBehavior = BottomSheetBehavior.from(bottomSheet)

        //Add Behavior logic here
    }

NOTE: No need of overriding onCreateDialog() unless you want your own Dialog to be initiated, i.e some other type of dialog.

Thank you for help but this is not working.Same exception was thrown – khushbu Dec 17 '18 at 07:52
while debugging can you check in which line this exception is triggered ! java.lang.IllegalArgumentException: No view found for id 0x7f0a01cb @khushbu – Anmol Dec 17 '18 at 08:38
if you remove `onCreateDialog()` then `getDialog()` in `onStart()` will return `null`, as the dialog has not been created. So, there will be a `NullPointerException` in the code you suggested. – Alexey Timokhin Aug 26 '19 at 07:56
No, it will not give NPE as `BottomSheetDialogFragment` has an implementation of `onCreateDialog` we should override it.It should be overridden only if you want to create custom dialog. @AlexeyTimokhin Can u tell me in what case u are getting NPE? – Anmol Aug 26 '19 at 09:33
@Anmol Yes, you are right. My mistake was that I was adjusting the `BottomSheetBehaviour` in `onCreateView()` and there `getDialog()` returned `null`. In `onStart()` it's not `null`, so I moved the adjustments there and it worked fine. Thank you! – Alexey Timokhin Aug 26 '19 at 12:20
This works for me. The main point is the childFragmentManager.beginTransaction(). You can find the code here https://github.com/jiahaoliuliu/SimpleLayoutTransitions – jiahao Aug 06 '20 at 12:24
