Invisible Layout not visible when make it visible in Android

Invisible Layout not visible when make it visible in Android - android

I am trying to implement something like viewing a list of items in RecyclerView (id=schedule_recycler_view) which parent layout is a CardView (id = info_card_view). The Item is fetched by API call. If no item found, or connectivity issue, I want to view another layout (id = no_list_layout) which is Visibility-Gone at the first time.
But The problem I face, although I make the visibility of that layout (id = no_list_layout) visible programmatically, it did not visible.
Can anyone help?
Here the code what I tried
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent">

in kotlin file
class TutorScheduleFragment : BaseFragment() {
private val tuitionScheduleAdapter by lazy {
TutorScheduleAdapter {
context?.showToast(it.day)
}
}
private val viewModel: TutorScheduleViewModel by lazy {
getViewModel {
TutorScheduleViewModel(
PreferenceService(context?.getSharedPreference()!!)
)
}
}
override fun getLayoutResId() = R.layout.fragment_tutor_schedule
override fun onResume() {
viewModel.getSchedule(jobTutorId!!)
}
override fun observeLiveData() {
viewModel.tuitionScheduleUiState.observe(this#TutorScheduleFragment, Observer {
it.getContentIfNotHandled()?.let { state ->
when (state) {
is Progress -> {
if (state.isLoading) {
} else {
}
}
is Success -> {
val schedules = state.successInfo.data
if (scheduleData.schedules.size == 0) {
no_list_layout.visibility = View.VISIBLE
} else {
tuitionScheduleAdapter.notifyChanged(scheduleData.schedules)
}
}
is Alert -> context?.showToast(state.alert)
is Failure -> {
if (state.throwable is IOException) {
context?.showToast("Internet Connection Failed")
} else {
context?.showToast("Json Parsing Error")
}
}
}
}
})
}
}

You should use no_list_layout.visibility = View.VISIBLE

Change your view visibility code
try this :
Kotlin:
if (list.size == 0) {
no_list_layout.visibility= View.VISIBLE
} else {
adapter.notifyChanged(list)
}
In Java
if (list.size == 0) {
no_list_layout.setVisibility(View.VISIBLE)
} else {
adapter.notifyChanged(list)
}

You can try with runOnUiThread.
runOnUiThread runs the specified action on the UI thread. If the
current thread is the UI thread, then the action is executed
immediately. If the current thread is not the UI thread, the action is
posted to the event queue of the UI thread.
context?.runOnUiThread(Runnable {
// Your Logic
if (list.size==0) {
no_list_layout.visibility= View.VISIBLE
} else {
// Your work
}
})

You have to hide your recyclerview also and make it visible in the other case like this:
if (scheduleData.schedules.size == 0) {
schedule_recycler_view.visibility = View.GONE
no_list_layout.visibility = View.VISIBLE
} else {
schedule_recycler_view.visibility = View.VISIBLE
no_list_layout.visibility = View.GONE
tuitionScheduleAdapter.notifyChanged(scheduleData.schedules)
}

At last, I found the actual culprit. It was in the layout file. I recreate the layout

Scroll to top of RecyclerView using setOnClickListener

I have this home button in top bar:
val activity: ImageButton =findViewById(R.id.activity)
activity.setOnClickListener{
startActivity(Intent(this, ActivitySearch::class.java))
}
Instead of going to a new page, I want to be able to just put a "to top" intent, I have tried to replace:
startActivity(Intent(this, ActivitySearch::class.java))
with
mRecyclerView.smoothScrollToPosition(0);
But this does not work, any ideas? I do have a RecyclerView in use so half way down, I want to be able to click the above button and it goes straight to the top.
Total code:
private val apiService by lazy {
ApiClient.create()
}
private var taskData : ArrayList<TaskResponse> = arrayListOf();
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val activity: ImageButton =findViewById(R.id.activity)
activity.setOnClickListener{
startActivity(Intent(this, ActivitySearch::class.java))
}
val searchbutton:ImageButton=findViewById(R.id.searchbutton)
searchbutton.setOnClickListener{
startActivity(Intent(this, ActivitySearch::class.java))
}
val saves:ImageButton=findViewById(R.id.saves)
saves.setOnClickListener{
startActivity(Intent(this, ActivitySaves::class.java))
}
val settings:ImageButton=findViewById(R.id.settings)
settings.setOnClickListener{
startActivity(Intent(this, ActivitySettings::class.java))
}
loadData();
}
private fun loadData(){
var data = apiService.getMainData();
data.enqueue(object : Callback<ArrayList<TaskResponse>> {
override fun onResponse(
call: Call<ArrayList<TaskResponse>>,
response: Response<ArrayList<TaskResponse>>
) {
if (response.code() == 200) {
taskData = response.body()!!;
displaydata();
}
}
override fun onFailure(call: Call<ArrayList<TaskResponse>>, t: Throwable) {
Log.d("-----------------", t.toString())
}
})
}
private fun displaydata(){
var recyclerView = findViewById<RecyclerView>(R.id.mainList);
var adapter = TaskAdapter(this, taskData);
recyclerView.layoutManager = LinearLayoutManager(this)
recyclerView.adapter = adapter
val swipeRefreshLayout: SwipeRefreshLayout = findViewById(R.id.swipeRefreshLayout)
// load data on swipe refresh.
swipeRefreshLayout.setOnRefreshListener { loadData() }
// Disable the refreshing after data load
swipeRefreshLayout.isRefreshing = false
}

This should work for going to the top of the recyclerView.
mRecyclerView.smoothScrollToPosition(0);
or
mRecyclerView.scrollToPosition(0);
When your list changes in recyclerView adapter, you should use that code. Make sure other parts of the code. This should work.

Using a comments answer from #cactustictacs, I edited my code to this and it worked:
val activity: ImageButton =findViewById(R.id.activity)
val mRecyclerView = findViewById<RecyclerView>(R.id.mainList)
activity.setOnClickListener{
mRecyclerView.smoothScrollToPosition(0)
}

How to Make Static Navigation Android Tablet? like this design

Hi I'm having trouble on making layout like this design because the navigation bar is difficult to make it become functional.
this is the design
I have created the class like this:
class MainActivity : AppCompatActivity() {
lateinit var navigationView: NavigationView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
navigationView = findViewById(R.id.navigation)
navigationView.setNavigationItemSelectedListener(mOnNavigationItemSelectedListener)
}
private val mOnNavigationItemSelectedListener =
BottomNavigationView.OnNavigationItemSelectedListener { item ->
when (item.itemId) {
R.id.navigation_user -> {
val fragment = UserFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_scaner -> {
val fragment = ScannerFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_laporan -> {
val fragment = LaporanFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_notif ->{
val fragment = NotificationFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_chat -> {
val fragment = LaporanFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_profile -> {
val fragment = LaporanFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
}
false
}
private fun addFragment(fragment: Fragment) = supportFragmentManager
.beginTransaction()
.setCustomAnimations(R.anim.design_bottom_sheet_slide_in, R.anim.design_bottom_sheet_slide_out)

I have tried several navigation listener such as navigationView.setNavigationItemSelectedListener(mOnNavigationItemSelectedListener)
But it won't work. Maybe someone know how I can solve my problem? Thanks in advance

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

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));

set Image from ImageView to Dialog

I'm passing a String url from Fragment A to B, and load to imageView
if (obj?.signature_image?.url != null) {
Glide.with(activity)
.load(obj?.signature_image?.url.toString())
.into(imgSignature)
}
When the imgSinature is clicked, a custom dialog will be pop up, and I want to set the image to the dialog. How can I achieve?
signDialog = Util().dialogSignature(getActivity())
imgSignature.setOnClickListener {
signDialog.show()
if (obj?.signature_image?.url != null) {
signDialog.relativeLayout2.addView(obj?.signature_image?.url)
}
}
Util
fun dialogSignature(context: Context?):Dialog{
var dialog = Dialog(context)
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
dialog.setContentView(R.layout.dialog_signature)
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT);
return dialog
}

Error in this line signDialog.relativeLayout2.addView(obj?.signature_image?.url)

Really annoying....
It looks like your post is mostly code; please add some more details.

You are trying to add a url string to a view which is wrong.
Add an ImageView inside your relativeLayout2 and use Glide to load your image url
<RelativeLayout
android:layout_width="0dp"
android:layout_height="0dp"
android:id="#+id/relativeLayout2"
android:background="#color/colorWhite"
app:layout_constraintTop_toBottomOf="#+id/linearLayout1"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintHorizontal_bias="1.0">
<ImageView
android:id="#+id/your_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>
and in your onClick
imgSignature.setOnClickListener {
...
Glide.with(activity)
.load(obj?.signature_image?.url.toString())
.into(signDialog.your_image)
}

You have to add an ImageView in dialog_signautre.xml and then pass the signature_image?.url in a second parameter and set it like this
fun dialogSignature(context: Context?,url:String?):Dialog{
var dialog = Dialog(context)
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
dialog.setContentView(R.layout.dialog_signature)
val imgSignature = dialog.findViewById<ImageView>(your_imageview_id)//added this line
Glide.with(activity)
.load(obj?.signature_image?.url.toString())
.into(imgSignature) //added this line
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT);
return dialog
}

RecyclerView cells deform when keyboard opened

I am implementing a chat inside my app, and the recycler view behave in wired way when the keyboard opened, the cards expands by itself
