Fragment Manager adding wrong fragment

Fragment Manager adding wrong fragment - android

A Button in Fragment A is given an onClickListener to go to Fragment B in Fragment A's onStart:
override fun onStart() {
enterMemberIDButton = view!!.findViewById(R.id.enter_member_id_button)
enterPlateButton = view!!.findViewById(R.id.enter_plate_button)
enterMemberIDButton.setOnClickListener {
activity?.supportFragmentManager?.beginTransaction()
?.replace(R.id.main_view_pager, FragmentB.newInstance())?.addToBackStack(null)?.commit()
}
}
However, the button click loads Fragment C, as confirmed by a debug line I placed in Fragment C's onStart.
Here is Fragment A's xml:

override fun onStart() {

val editText: TextInputEditText = view!!.findViewById(R.id.member_edit_text)
val keyboard: SoftKeyboard = view!!.findViewById(R.id.enter_id_keyboard)
println("ID Fragment34")
keyboard.init(context!!)
val inputConnection = editText.onCreateInputConnection(EditorInfo())
keyboard.inputConnection = inputConnection
}
companion object {
#JvmStatic
fun newInstance() =
HaveCodeFragment().apply {
}
}
}
Is there anything else that could be rerouting this to the wrong fragment?

The MemberIDFragment is returning an instance of the HaveCodeFragment().
Should change the newInstance() method of the MemberIDFragment to:
companion object {
#JvmStatic
fun newInstance() = MemberIDFragment()
}

TextView in ConstraintLayout (for MaterialCardView) not in vertical centre

I'm trying to vertically align my TextView to the centre using constraints within my MaterialCardView but it won't move at all for some reason. Does anyone know what's causing this problem to occur? Do constraints need to be used at all to achieve this? The affected component is the MaterialCardView with a white border. The word 'Information' + the drawable don't seem to be exactly in the vertical centre for some reason. It looks like there is a bit more space above the text view than below it for some strange reason (indicated by the orange line).

Just remove app:layout_constraintHorizontal_bias="0.0"
The maximum is app:layout_constraintHorizontal_bias="1.0"
When you set "0.0" that mean you want it to the left and when it is "1.0" that mean it is to the right.

Android TextInputLayout slow rendering inside a RecyclingView

I'm using multiple TextInputLayout in each element in a Recycling View.
I noticed that navigating to the fragment containing this list is slow and scrolling for the first few seconds is also slow. As soon as I remove the TextInputLayout the performance drastically improves.
Is there a way to render the TextInputLayout in a recycling view with a good performance?
I mostly want to use this layout for its animations and design.
This is my layout for a individual item in recycling view:

Fragment code:

return inflater.inflate(R.layout.fragment_edit_routine, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
val adapter = EditRoutineListAdapter()
requireView().rv_list.apply {
this.adapter = adapter
layoutManager = LinearLayoutManager(context)
setHasFixedSize(true)
}
}
}
Recycling View Adapter
class EditRoutineListAdapter: RecyclerView.Adapter<EditRoutineListAdapter.ViewHolder>() {
class ViewHolder(itemView: ViewGroup): RecyclerView.ViewHolder(itemView)
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val view = LayoutInflater
.from(parent.context)

return ViewHolder(view)
}
override fun getItemCount() = 16
override fun onBindViewHolder(holder: ViewHolder, position: Int) {

}

You can leftout the ImageButton and use the built in option like:
app:endIconMode="custom"
app:endIconDrawable="#drawable/ic_check_circle_24dp"
app:endIconContentDescription="#string/content_description_end_icon"
Check also RecyclerView on Bind method taking too long(that is, onBindViewHolder(VH, int)) should be very simple, and take much less than one millisecond for all but the most complex items.

Disable certain part of fragment for scrolling even though it's inside a nested scrollview

Currently I am finishing the last details of my project and I am trying to keep a certain part inside a nested scrollview to stay on top of the screen and let only the recyclerview scroll.

}
}
Does anyone have a solution for this awkward problem? I've been trying to do some restructuring of the swiperefreshlayout, scrollviews and constraints but no succes so far.
I also can't find anything on the internet where someone wants the same as me...

As per your question description, I am assuming that you face an issue that recycler view scroll or take focus automatically while you open screen and you need to stick layout at the top so pass this field on your parent layout.
android:descendantFocusability="blocksDescendants"
or replace your SwipeRefreshLayout
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:id="#+id/marktplaats_refresh"
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:descendantFocusability="blocksDescendants"
android:layout_height="match_parent">
I hope it helps you.

Display of the dialog in my fragment:
val fragment = NoRetailsNearbyDialogFragment.newInstance()
fragment.show(fragmentManager, "")
I really can't understand why the textview has this strange behavior.

there is one method, you can set textview typeface by calling setTypeface method,
see the following
your can do it programatically as:
textView.setTypeface(null, Typeface.BOLD);
or you can do it by html approach as:
TextView t = new TextView(mContext);
t.setText(Html.fromHtml("<b>This is bold</b>"));

Problem was related to Calligraphy library that was overriding common textStyle behavior. Once I removed it, everything started to work fine :)

Android gridview in fragment can't scrolling

I have one page called products. When page is loaded it shows productsfragment. This fragment has one RecyclerView which doesn't have any problem. On selecting a product a new fragment opens up and shows the list of product prices fragment. This fragment has one RecyclerView and the scrolling here doesn't works.
I tried gridview and cardview but they too are not scrolling. I tried gridview in scroll view or nested scroll view, they are also not scrolling.
here is my fragment with RecyclerView which is not scrolling
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/sorderfragment_step1_layout"

<android.support.v7.widget.RecyclerView
android:id="#+id/gvProductPrices"

and its my RecyclerView item view

class PriceAdapter(val priceList : List<ProductPrice>,

}
}
class ViewHolder (view: View) : RecyclerView.ViewHolder(view) {
val txtPriceName = view.txtPriceName!!
val txtPrice = view.txtPrice!!
}
and my fragment code
class SOrderFragment_Step1 : Fragment() {
private var _priceRepository = ProductPriceRepository(OrderRepository.orderSelect!!)
private var priceAdapter: PriceAdapter? = null
private var prices: List<ProductPrice>? = null

}
fun priceSelect(price: ProductPrice) {
Toast.makeText(OrderRepository.orderSelect!!, price.getDescription(), Toast.LENGTH_LONG).show()
}
}
and also fragment change like this
val manager = this.fragmentManager!!.beginTransaction()
manager.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out)
manager.replace(R.id.fragmentProductSteps, SOrderFragment_Step1(), "detailFragment").commit()

How can i fix this issue ?

Sugession: Why are you using grid view and setting adapter to it where you have another approach and commonly used approach.
Which is to use recycler view and set its layout manager as GridLayout manager
Below single line will make your job done
recyclerView.setLayoutManager(new GridLayoutManager(this, numberOfColumns));

Fragment Manager adding wrong fragment - android

The MemberIDFragment is returning an instance of the HaveCodeFragment(). Should change the newInstance() method of the MemberIDFragment to: companion object { #JvmStatic fun newInstance() = MemberIDFragment() }
