Android :switch between Layouts dynamically every 10 seconds

android beginner here. any help is much appreciated .
I am working on an app that can do a simple experiment.
the app displays images and asks users to rate it from 1 to 10.
I have 1 activity and two layouts experiment begins.
I have two layouts merged under FrameLayout.
what I want to achieve is :
'====>start experiment >show first image for 10 seconds >change layout to ratings layout>after user selects rating>loopback with different image>finish() when imagelist is empty. '
here is what I tried
I have tried viewflipper but shownext() and showprevious() methods dont update values.
now i am trying using layout visibility ,showing and hiding the layouts
class Presenter : AppCompatActivity() {
//val currentTime = Calendar.getInstance().time
private lateinit var binding: ActivityPresenterBinding
lateinit var layout1:View
lateinit var layout2:View
val imgList=Constants.getImages()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
//setContentView(R.layout.activity_presenter)
binding = ActivityPresenterBinding.inflate(layoutInflater)
setContentView(binding.root)
layout1 = binding.imageView
layout2=binding.ratingView
startSlider()
}
private fun startSlider() {
Handler(Looper.getMainLooper()).apply {
//arr.shuffle()
var index = 0
var imageView = binding.imgPresenter
val runnable = object : Runnable {
override fun run() {
imageView.setImageResource(imgList[index].image)
layout1.visibility= View.VISIBLE
Log.i("number ","${index}")
postDelayed(this, 5000)
index++
layout1.visibility=View.GONE
layout2.visibility=View.VISIBLE
binding.sbSeekbar.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener{
override fun onProgressChanged(p0: SeekBar?, p1: Int, p2: Boolean) {
Toast.makeText(applicationContext, "$p1", Toast.LENGTH_LONG).show()
//save rating (1-10)
}
override fun onStartTrackingTouch(p0: SeekBar?) {
}
override fun onStopTrackingTouch(p0: SeekBar?) {
}
})
}
}
postDelayed(runnable, 1000)
}
}
here my layout file
<FrameLayout android:id="#+id/viewFliper"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="#+id/img_presenter"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/ic_bg"
/>
</LinearLayout>
<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:id="#+id/ratingView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="16dp"
>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="how do you feel about this image from one to 10"
android:orientation="vertical"
android:gravity="center"
android:layout_marginBottom="20dp"
/>
<SeekBar
android:id="#+id/sb_seekbar"
style="#style/Widget.AppCompat.SeekBar.Discrete"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:max="10"
android:paddingStart="6dp"
android:paddingEnd="6dp"
android:progress="3"
android:stepSize="1" />
</LinearLayout>
this is not hiding the views after the second image
what am I doing wrong?

try this and apply viewbinding
lateinit var runnable: Runnable
private fun startSlider() {
Handler(Looper.getMainLooper()).apply {
var flag = 0
var index = 0
runnable = Runnable {
if (flag == 0) {
img_presenter.setImageResource(imgList[index])
layout1.visibility = View.VISIBLE
layout2.visibility = View.GONE
postDelayed(runnable, 5000)
flag = 1
index++
} else {
layout1.visibility = View.GONE
layout2.visibility = View.VISIBLE
sb_seekbar.setOnSeekBarChangeListener(object :
SeekBar.OnSeekBarChangeListener {
override fun onProgressChanged(p0: SeekBar?, p1: Int, p2: Boolean) {
// Toast.makeText(applicationContext, "$p1", Toast.LENGTH_LONG).show()
//save rating (1-10)
}
override fun onStartTrackingTouch(p0: SeekBar?) {
}
override fun onStopTrackingTouch(p0: SeekBar?) {
index++
flag = 0
postDelayed(runnable, 1000)
}
})
}
}
postDelayed(runnable, 1000)
}
}

How to display JSON data from Horizontal recycle view kotlin using MVP method

I hope is all well with you.
I have constructed my code and build according the MVP style as well pulling JSON data but when I run the the code the horizontal recycle view and the JSON data is not being displayed. I tried going through every line of code and watching other tutorials but still no results.
Here is below my main activity:
class ProductCategoryActivity : BaseMvpActivity<ProductCategoryActivityView, ProductCategoryActivityPresnter> (),
ProductCategoryActivityView, CategoryAdapter.onItemClickListener{
private lateinit var binding: FragmentProductCategoryBinding
val data :MutableList<CateogryResponse> = ArrayList()
val adapter= CategoryAdapter(data, this)
#Inject
lateinit var presenter: ProductCategoryActivityPresnter
#Inject
lateinit var progressDialog: ProgressDialog
override fun onCreateComponent() {
userComponent.plus(CategoryActivityModule(this)).inject(this)
}
override fun providePresenter(): ProductCategoryActivityPresnter {
return presenter
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = FragmentProductCategoryBinding.inflate(layoutInflater)
val view = binding.root
setContentView(view)
presenter.fetchcatogries()
showdata(ArrayList())
}
override fun showError(message: String) {
}
override fun showProgress() {
}
override fun hideProgress() {
}
override fun showdata(data: ArrayList<CateogryResponse>) {
val layoutManager = LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)
recyclerViewPrimary.layoutManager = layoutManager
recyclerViewPrimary.setHasFixedSize(true)
recyclerViewPrimary.adapter = adapter
for(i in data)
data.add(CateogryResponse("product"))
}
override fun onItemClick(position: Int) {
Toast.makeText(this, "Item $position clicked", Toast.LENGTH_SHORT).show()
val clickedItem = data[position]
adapter.notifyItemChanged(position)
}
}
Here is my presenter:
#ActivityScope
class ProductCategoryActivityPresnter #Inject constructor(
private val stringProvider: StringProvider,
#AndroidScheduler private val observeOnScheduler: Scheduler,
#IOScheduler private val subscribeOnScheduler: Scheduler,
private val getCategoryUseCase: CategoryUseCase
) : BasePresenter<ProductCategoryActivityView>() {
lateinit var catogriesservice: CategoryRepositoryImpl
val catogriesLoadError = MutableLiveData<Boolean>()
val loading = MutableLiveData<Boolean>()
var catogries: ArrayList<CateogryResponse> = arrayListOf()
override fun onCreatePresenter(savedInstanceState: Bundle?) {
}
override fun onSaveInstanceState(outState: Bundle?) {
}
override fun onLoadData(arguments: Bundle?) {
fetchcatogries()
}
fun fetchcatogries() {
getCategoryUseCase.execute()
.observeOn(observeOnScheduler)
.subscribeOn(subscribeOnScheduler)
.subscribe(
SingleRequestSubscriber(
{
it
if (it != null && it.size > 0) {
catogries.removeAll(catogries)
catogries.addAll(it)
}
},
onFailure = { appException ->
view?.showError(
ErrorHandler.getErrorMessage(
appException,
stringProvider
)
)
},
onApiError = { apiException ->
view?.showError(
ErrorHandler.getErrorMessage(
apiException,

)
},
onAuthenticationError = { requestxception ->
view?.showError(
ErrorHandler.getErrorMessage(
requestxception,
stringProvider
)
)
},
onShowProgress = {
if (it) {
view?.showProgress()
} else {
view?.hideProgress()
}
},
onSubscribed = {
disposable.add(it)
})
)
}
}
Here is my view:
interface ProductCategoryActivityView {
fun showError(message: String)
fun showProgress()
fun hideProgress()
fun showdata ( data: ArrayList<CateogryResponse>)
}
Here is my adapter:
class CategoryAdapter(
private val data: List<CateogryResponse>,
private val listener: onItemClickListener
) : RecyclerView.Adapter<CategoryAdapter.ViewHolder>() {
private val items: MutableList<CardView>
init {
this.items = ArrayList()
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val v = LayoutInflater.from(parent.context)
.inflate(R.layout.fragment_category_adapter, parent, false)
return ViewHolder(v)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.tvTitle.text = data[position].product
items.add(holder.card)
}
override fun getItemCount(): Int {
return data.size
}
inner class ViewHolder(itemView: View

View.OnClickListener {
val tvTitle: TextView = itemView.featured_title

init {
itemView.setOnClickListener(this)
}
override fun onClick(v: View?) {

}
}

Not sure what went wrong.
If someone can point it out or show me what needs to be done to be able to display the data in horzintal recycle view, I would be really thanlful

You should update your recycler view adapter once your fetch call is executed, not before it ends.
Modify your fetchcatogries declaration so it accepts a callback method, which will be executed after the data are loaded.
This method will accept a list object as a parameter, which you will manage in your ProductCategoryActivity to populate the RecyclerView.
fun fetchcatogries(callback: (MutableList<CateogryResponse>) -> Unit) {
getCategoryUseCase.execute()
.observeOn(observeOnScheduler)
.subscribeOn(subscribeOnScheduler)
.subscribe(
SingleRequestSubscriber(
{ categories ->
callback(categories)
},
...
)
}
You can now edit your onCreate and showdata methods in ProductCategoryActivity like this:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = FragmentProductCategoryBinding.inflate(layoutInflater)
val view = binding.root
setContentView(view)
presenter.fetchcatogries { categories ->
showdata(categories as ArrayList<CateogryResponse>)
}
}
override fun showdata(data: ArrayList<CateogryResponse>) {
val layoutManager = LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)
recyclerViewPrimary.layoutManager = layoutManager
recyclerViewPrimary.setHasFixedSize(true)
recyclerViewPrimary.adapter = CategoryAdapter(data.toList(), this)
}

Gravity:End is not taking effect Programmatically

I am giving gravity:end in xml and it shows at the right side in Android Studio. (go end)
but programmatically doesn't work.
layout_gravity:end in chat_image worked just in Android Studio preview but it's not working programmatically.
changed item_parent to RelativeLayout but not work and same with LinearLayout
All possible cases I did when I saw right preview in xml with attributes gravity or layout_gravity if possible.
I think the problem related to Glide

BottomSheet is jumping on button clicks

I have a BottomSheet which houses a product detail card. The problem is, when I click on the + or - button on the product detail while the bottom sheet is in it's Expanded state, it jumps down.
When it is down and I click on the buttons it doesn't jump, it only happens when it is in it's Expanded (completely up) state
I have attached a GIF to show what is exactly happening

it seems that google engineer gave correct answer
Seems like something is going on because you are setting
android:layout_gravity="bottom" on the view with the
BottomSheetBehavior. You should remove that line.
It helped on my case

Looks to me like that could be a bug in the BottomSheetBehavior? Seems like the height of the sheet isn't getting saved or restored correctly. After the button is pressed, a layout happens again which changes the height. Could you file a bug at https://issuetracker.google.com/issues/new?component=439535

DSL-like OnClick-listener for a custom view using kotlin in Android

I'm trying to create an DSL-like OnClick-listener (in kotlin) for a custom view that I'm using several places in the Android project I'm currently working on. The view has an ImageView, a primary textview and a secondary textview. I'm trying to create a listener-helper that allows you to only override specific methods of an interface instead of all of them (inspired by this article). But I can't get it working. Actually it doesn't even work using regular OnClick listeners.
Here's my ErrorMessageView:
class ErrorMessageView #JvmOverloads constructor(
context: Context,
attrs: AttributeSet? = null,
defStyle: Int = 0,
defStyleRes: Int = 0
) : FrameLayout(context, attrs, defStyle, defStyleRes) {
private var mOnClickListener: OnErrorMessageViewClickListener? = null
init {
LayoutInflater.from(context).inflate(
R.layout.custom_errorview,
this,
true)
ButterKnife.bind(this)
}
interface OnErrorMessageViewClickListener {
fun onImageClick()
fun onPrimaryTextClick()
fun onSecondaryTextClick()
}
... left out for brevity ...
fun setOnErrorMessageViewClickListener(
onViewClickListener: OnErrorMessageViewClickListener?) {
this.mOnClickListener = onViewClickListener
}
fun setOnErrorMessageViewClickListener(init: ErrorMessageViewClickListenerHelper.() -> Unit) {
val listener = ErrorMessageViewClickListenerHelper()
listener.init()
mOnClickListener = listener
}
#OnClick(R.id.image_container)
internal fun onImageViewClick() {
Timber.d("Clicked image view")
mOnClickListener?.onImageClick()
}
#OnClick(R.id.primary_text_container)
internal fun onPrimaryTextViewClick() {
Timber.d("Clicked primary textview")
mOnClickListener?.onPrimaryTextClick()
}
#OnClick(R.id.secondary_text_container)
internal fun onSecondaryTextViewClick() {
Timber.d("Clicked secondary textview")
mOnClickListener?.onSecondaryTextClick()
}
}
And here's my helper class:
private typealias ErrorViewClickListener = () -> Unit
open class ErrorMessageViewClickListenerHelper : ErrorMessageView.OnErrorMessageViewClickListener {
private var mImageClick: ErrorViewClickListener? = null
fun onImageClick(onImageClick: ErrorViewClickListener?) {
mImageClick = onImageClick
}
override fun onImageClick() {
mImageClick?..invoke()
}
private var mPrimaryTextClick: ErrorViewClickListener? = null
fun onPrimaryTextClick(onPrimaryTextClick: ErrorViewClickListener?) {
mPrimaryTextClick = onPrimaryTextClick
}
override fun onPrimaryTextClick() {
mPrimaryTextClick?.invoke()
}
private var mSecondaryTextClick: ErrorViewClickListener? = null
fun onSecondaryTextClick(onSecondaryTextClick: ErrorViewClickListener?) {
mSecondaryTextClick = onSecondaryTextClick
}
override fun onSecondaryTextClick() {
mSecondaryTextClick?.invoke()
}
}
My layout:
<?xml version="1.0" encoding="utf-8"?>

I'm using the helper in my code like this, but nothing gets logged (It's almost as if no clicklistener can be attached):
override fun setWorklistNotEnabledMessage(showMessage: Boolean) {
if (showMessage) {
mView?.dialog_worklist_recyclerview?.visibility = View.GONE
mView?.dialog_worklist_errorview?.apply {
visibility = View.VISIBLE
setSecondaryTextClickListener(View.OnClickListener { Timber.d("Test secondary click") })
setErrorDrawable(R.drawable.ic_worklist_disabled_black_24dp)
setPrimaryText(R.string.global_worklist_disabled_error)
setSecondaryText(R.string.dialog_worklist_worklist_disabled_error_secondary_text)
setOnErrorMessageViewClickListener {
onSecondaryTextClick { Timber.d("Test secondary click") }
onPrimaryTextClick { Timber.d("Test primary click") }
onImageClick { Timber.d("Test image click") }
// . this#WorklistDialog
}
}
} else {
mView?.dialog_worklist_errorview?.apply {
visibility = View.GONE
setErrorDrawable(null)
setPrimaryText("")
setSecondaryText("")
setOnErrorMessageViewClickListener(null)
}
}
}
Does anyone have a suggestion to what is wrong with my code?
Btw. the above code is used in a DialogFragment - that is why you might notice the mView?. as a bit awkward. But that is the way to get a handle on the views in a dialog.

Was just about to start crying when I finally found the solution - OMG.
The problem was the SwipeRefreshLayout in the layout file for the dialogfragment, which can be seen here:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/dialog_worklist_toolbar"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="#color/colorPrimary"
android:elevation="4dp"
android:minHeight="?android:attr/actionBarSize"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<com.conhea.smartgfr.ui.examination.layouts.ErrorMessageView
android:id="#+id/dialog_worklist_errorview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/dialog_worklist_toolbar" />
<ProgressBar
android:id="#+id/dialog_worklist_progressbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/dialog_worklist_toolbar" />
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/dialog_worklist_swiperefreshlayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
app:layout_constraintTop_toBottomOf="#id/dialog_worklist_toolbar">
<android.support.v7.widget.RecyclerView
android:id="#+id/dialog_worklist_recyclerview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/transparent" />
</android.support.v4.widget.SwipeRefreshLayout>
</android.support.constraint.ConstraintLayout>
The SwipeRefreshLayout was blocking the custom ErrorMessageView from being clickable.
After adding mView?.dialog_worklist_swiperefreshlayout?.isEnabled = false to the below in my DialogFragment everything started working:
override fun setWorklistNotEnabledMessage(showMessage: Boolean) {
if (showMessage) {
mView?.dialog_worklist_recyclerview?.visibility = View.GONE
mView?.dialog_worklist_swiperefreshlayout?.isEnabled = false
mView?.dialog_worklist_errorview?.apply {
visibility = View.VISIBLE
setErrorDrawable(R.drawable.ic_worklist_disabled_black_24dp)
setPrimaryText(R.string.global_worklist_disabled_error)
setSecondaryText(R.string.dialog_worklist_worklist_disabled_error_secondary_text)
setOnErrorMessageViewClickListener {
onSecondaryTextClick { Timber.d("Test secondary click") }
onPrimaryTextClick { Timber.d("Test primary click") }
onImageClick { Timber.d("Test image click") }
}
}
} else {
mView?.dialog_worklist_errorview?.apply {
visibility = View.GONE
setErrorDrawable(null)
setPrimaryText("")
setSecondaryText("")
setOnErrorMessageViewClickListener(null)
}
}
}
