When I click on order menu the app suddenly stopped working, and on the log show this error
image, it says java.lang.IllegalStateException: Fragment already added: InprogressFragment
I have 2 section pager on order menu, it's for inprogress & pastOrders.
here is the code

Try something like this(I didn't test this code, it's just a concept for your app):
enum class FragmentType {
IN_PROGRESS,
POSTORDERS
}
data class Data(

override fun getItem(position: Int): Fragment {

return when (item.fragmentType) {
FragmentType.IN_PROGRESS -> {
InprogressFragment().apply {
val bundle = Bundle()
bundle.putParcelableArrayList("data", item.orderList)
setArguments(bundle)
}
}
FragmentType.POSTORDERS -> {
PastordersFragment().apply {
val bundle = Bundle()
bundle.putParcelableArrayList("data", item.orderList)
setArguments(bundle)
}
}
}
}
override fun getPageTitle(position: Int): CharSequence {
return inprogressList[position].fragmentName
}
override fun getCount(): Int {
return inprogressList.size
}
fun setData(items: ArrayList<Data>) {
inprogressList = items
notifyDataSetChanged()
}

Fragment1 exists in MainActivity and Fragment2 exists in Fragment1.
Fragment2 contains a recycler view, and inside the recycler view there are items with a move button. When I click the go button, I want to switch to a screen other than the RcyclerView with the items currently displayed in Fragment2.

You are trying to access activities and fragments inside your adapter class which is incorrect. Never do that! Instead, create an item click listener and create a reference to it in your activity. This way you can handle item click in your activity and perform fragment transactions.
Here, You can take help on how to do so by making an onClickInterface
Here is when the list increase
I call data from API and place it in recycleview horizontal and vertical, but when I try to move on Profile Menu with bottom navigation and back again on Home Menu where my horizontal and vertical recycleview is, the data on recycleview start to increase, it only happen for vertical recycleview
Here is my code:
SectionPagerAdapter for vertical recycleview
class SectionsPagerAdapter(fm: FragmentManager) :

bundle.putParcelableArrayList("data", new_craft)
fragment.setArguments(bundle)
return fragment
}

fragment = HomePopularFragment()
val bundle = Bundle()
bundle.putParcelableArrayList("data", popular)
fragment.setArguments(bundle)
return fragment
}
2 -> {
fragment = HomeRecommendedFragment()
val bundle = Bundle()
bundle.putParcelableArrayList("data", recommended)
fragment.setArguments(bundle)
return fragment
}
else -> {
fragment = HomeNewCraftFragment()
val bundle = Bundle()
bundle.putParcelableArrayList("data", new_craft)
fragment.setArguments(bundle)
return fragment
}
}
}
override fun getPageTitle(position: Int): CharSequence? {
return when (position) {
0 -> "New Craft"
1 -> "Popular"
2 -> "Recommended"
else -> null
}
}
override fun getCount(): Int {
return 3
}
fun setData(newStateListParms: ArrayList<Data>?, popularListParms: ArrayList<Data>?, recomendedListParms: ArrayList<Data>?) {

override fun onClick(v: View?, data: Data) {
val detail = Intent(activity, DetailActivity::class.java).putExtra("data", data)
startActivity(detail)
}
}
When you leave from your HomeFragment and coming back again, your HomeFragment keeps the old newStateList and add same values in it again. So, you need to empty the values before adding new values.
override fun onHomeSuccess(homeResponse: HomeResponse) {
newStateList = ArrayList() // empty it before load it again.
for (a in homeResponse.data.indices) {
You might need to empty the recomendedList and popularList as well.
I try to pass data from API on recycleView on Home Activity to new activity and fragment, but I have a problem like this
java.lang.IllegalArgumentException: Required argument "data" is missing and does not have an android:defaultValue

}
}

Code for vertical recycleview fragment:

private var newcraftlist: java.util.ArrayList<Data>? = java.util.ArrayList()
private var test: String? = null

adapter = HomeNewCraftAdapter(newcraftlist!!, this)
val layoutManager: RecyclerView.LayoutManager = LinearLayoutManager(activity)
rcListNewCraft.layoutManager = layoutManager
rcListNewCraft.adapter = adapter
}
override fun onClick(v: View?, data: Data) {
val detail = Intent(activity, DetailActivity::class.java).putExtra("data", data)
startActivity(detail)
}
}
And I want to pass data here, on Detail Activity:
class DetailActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_detail)
intent.extras?.let {
val navController = Navigation.findNavController(findViewById(R.id.detailHostFragment))
val bundle = Bundle()
bundle.putParcelable("data", it.get("data") as Parcelable?)
navController.setGraph(navController.graph, bundle)
}
}
fun toolbarPayment() {
toolbar.visibility = View.VISIBLE
toolbar.title = "Payment"
toolbar.subtitle = "You deserve better meal"
toolbar.navigationIcon = resources.getDrawable(R.drawable.arrow_back)
toolbar.setNavigationOnClickListener { onBackPressed() }
}
fun toolbarDetail() {
toolbar.visibility = View.GONE
}
}
And fragment:
class DetailFragment : Fragment() {
var data:Data?= null
var bundle:Bundle?= null
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?, savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.fragment_detail, container, false)
}
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
(activity as DetailActivity?)!!.toolbarDetail()
arguments?.let {
DetailFragmentArgs.fromBundle(it).data.let {
initView(it)
}
}
btnOrderNow.setOnClickListener { view ->
Navigation.findNavController(view).navigate(R.id.action_fragmentDetail_to_fragmentPayment, bundle)
}
}
private fun initView(data: Data?) {
bundle = bundleOf("data" to data)
Glide.with(requireContext())
.load(data?.picturePath)
.into(ivPoster)
tvTitle.text = data?.name
tvDescription.text = data?.description
tvMaterials.text = data?.materials
// tvTotal.formatPrice(data?.price.toString())
}
}
and here is the navigation:
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
app:startDestination="#id/fragmentDetail"
android:id="#+id/nav_detail">
<fragment
android:id="#+id/fragmentDetail"
android:name="com.project.icacraft.ui.detail.DetailFragment"
tools:layout="#layout/fragment_detail">
<action
android:id="#+id/action_fragmentDetail_to_fragmentPayment"
app:destination="#id/fragmentPayment" />
<argument
android:name="data"
app:argType="com.project.icacraft.model.response.home.Data"
app:nullable="true" />
</fragment>
Here is xml for activiy_detail:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".ui.detail.DetailActivity">
//Menambahkan toolbar dan detail fragment
<include
android:id="#+id/include_toolbar"
layout="#layout/layout_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<fragment
android:id="#+id/detailHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="androidx.navigation.fragment.NavHostFragment"
app:defaultNavHost="true"
app:navGraph="#navigation/nav_detail"
/>
</LinearLayout>
As per the Pass data to the start destination documentation:
Note: when manually calling setGraph() with arguments, you must not use the app:navGraph attribute when creating the NavHostFragment in XML as that will internally call setGraph() without any arguments, resulting in your graph and start destination being created twice.
So you can fix your error by removing the app:navGraph="#navigation/nav_detail" line from your activity_detail.xml file.
You'll also need to change your setGraph call to use the same R.navigation.nav_detail:
navController.setGraph(R.navigation.nav_detail, bundle)
I have a dynamic Viewpager and I add pages with title. In Viewpager I have and Setting button that sends you in new Activity but when I go back in ViewPager all my views which I have added have deleted. What should I do to not lose views??

This is the fragment which inherite the views that creates from the Add Button
class FragmentChild : Fragment() {
var childname: String? = null
var textViewChildName: TextView? = null
var editText: TextView? = null
#Nullable
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View {
val view: View = inflater.inflate(R.layout.fragment_child, container, false)
val bundle: Bundle? = getArguments()
childname = bundle!!.getString("data")
getIDs(view)
setEvents()
return view
}
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
}
private fun getIDs(view: View) {
textViewChildName = view.findViewById<View>(R.id.textViewChild) as TextView
textViewChildName!!.text = childname
editText = view.findViewById<View>(R.id.editText) as TextView
editText!!.setText("")
}
private fun setEvents() {}
}
In this class I create the list with fragments
class ViewPagerAdapter(manager: FragmentManager?, var context: Context, viewPager: ViewPager, tabLayout: TabLayout) : FragmentStatePagerAdapter(manager!!) {
private val mFragmentList: ArrayList<Fragment> = ArrayList<Fragment>()
private val mFragmentTitleList = ArrayList<String>()
private val mFragmentBtnCloseList = ArrayList<Boolean>()
override fun getItem(position: Int): Fragment {
return mFragmentList[position]
}
override fun getCount(): Int {
return mFragmentList.size
}
fun addFrag(fragment: Fragment, title: String, btn_close: Boolean) {
mFragmentList.add(fragment)
mFragmentTitleList.add(title)
mFragmentBtnCloseList.add(btn_close)
val globalClass = context.getApplicationContext() as GlobalClass
globalClass.setFragmentList(mFragmentList)
globalClass.setFragmentTitleList(mFragmentTitleList)
globalClass.setFragmentBtnCloseList(mFragmentBtnCloseList)
Log.d("setFragmentList", mFragmentList.toString())
Log.d("mFragmentTitleList", mFragmentTitleList.toString())
}
}
Here is the Setting Page with back button with globalClass i see I have
the data but when go back in Main Activity I lose my data
Setting
class Setting : AppCompatActivity() {
private var btn_back: Button? = null
var fragmentParent: FragmentParent? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_setting)
val globalClass = applicationContext as GlobalClass
fragmentParent = this.supportFragmentManager.findFragmentById(R.id.fragmentParent) as FragmentParent?
btn_back = findViewById(R.id.btn_back)
btn_back!!.setOnClickListener {
val intent = Intent(this#Setting, MainActivity::class.java)
//fragmentParent!!.marios()
globalClass.getFragmentList()
globalClass.getFragmentTitleList()
globalClass.getFragmentBtnCloseList()
startActivity(intent)
}
}
}
I try get data from internet, after done i update my Recyclerview, but it never show. Method onDone() Toast size of result, it's not empty.
My code:
class SearchFragment : Fragment() {
private lateinit var requestSearchPresenter: RequestSearchPresenter
private lateinit var recyclerViewAdapter: RecyclerViewAdapter
private var searchResult = ArrayList<ItemNewFeedCollection?>()
private val onRequestSearchResult = object : OnRequestSearchResult {
override fun onEmpty(result: ListNewFeedCollection) {
recyclerViewAdapter.notifyDataSetChanged()
}
override fun onDone(result: ListNewFeedCollection) {
searchResult = result.post
Toast.makeText(requireContext(), "${searchResult.size}", Toast.LENGTH_SHORT).show()
recyclerViewAdapter.notifyDataSetChanged()
}
override fun onFail(t: String) {
recyclerViewAdapter.notifyDataSetChanged()
}
}
private var recyclerViewItemClickListener = object : OnRecyclerViewItemClickListener {
override fun onItemClick(view: View, postion: Int) {
(requireActivity() as NewFeedActivity).apply {
val post = searchResult
if (post[postion]!!.date == "null" && post[postion]!!.date == post[postion]!!.description &&
post[postion]!!.date == post[postion]!!.full_post && post[postion]!!.date == post[postion]!!.image &&
post[postion]!!.date == post[postion]!!.full_post
) {
} else {
val link = post[postion]!!.link
val source = post[postion]!!.source
val intent = Intent(requireContext(), PostActivity::class.java)
intent.putExtra("link", link)
intent.putExtra("source", source)
startActivity(intent)
}
}
}
override fun onLongItemClick(view: View, postion: Int) {
}
}
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_search, container, false)
}
private fun configRecyclerView() {
recyclerViewAdapter = RecyclerViewAdapter(requireContext(), searchResult, recyclerViewItemClickListener)
recycler_view.layoutManager = LinearLayoutManager(requireContext())
recycler_view.adapter = recyclerViewAdapter
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
configRecyclerView()
val keyWord = arguments?.getString("key_word")
keyWord?.let {
requestSearchPresenter = RequestSearchPresenter(onRequestSearchResult)
requestSearchPresenter.search(it)
}
}
}
But i move method configRecyclerView() to onDone(), it show on:
override fun onDone(result: NewFeedCollection) {
searchResult = result.post
Toast.makeText(requireContext(), "${searchResult.size}", Toast.LENGTH_SHORT).show()
configRecyclerView()
recyclerViewAdapter.notifyDataSetChanged()
}
in fun onDone you are reassigning the result: searchResult = result.post
Instead of that you have to update the list's reference you've passed to the adapter initially. That means you need to change the code:
from:
searchResult = result.post
to
searchResult.clear();
searchResult.addAll(result.post);
