Error in using Recycler View and Scroll View together? - java

I have been facing issue using Recycler View and Scroll View together in the same bottom navigation activity in different tabs. I am hiding one of the view by using Visibility Gone in the java file.
I tried many solutions but nothing worked till now so I am posting here if someone can help me figure it out.

Fragment class
Java
Objects.requireNonNull(getActivity()).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
also added attributes in manifest file
<activity android:name=".view.AssessmentActivity"
android:theme="#style/AppTheme.NoActionBar"
android:screenOrientation="portrait"
android:windowSoftInputMode="adjustPan"
/>

Here I have two solutions. They might be helpful for you.
android:windowSoftInputMode="adjustResize|stateHidden"
or
Simply adding this to the parent layout:
android:fitsSystemWindows="true"

RecyclerView not scrolling inside NestedScrollView

I'm designing a complex UI that has a NestedScrollView as a parent and inside it, there is a RecyclerView. Now the problem is that I'm not able to scroll the items inside the RecyclerView.
Things I've tried
Replacing ScrollView with NestedScrollView
Enabling android:fillViewport="true"
Disabling NestedScrolling of RecyclerView

Use a NestedScrolView and add this to your RecyclerView:
recyclerView.setNestedScrollingEnabled(false);
recyclerView.setHasFixedSize(false);
Or this to the XML:
android:nestedScrollingEnabled="false"
Also it might help to add orientation to the recyclerView:
android:orientation="vertical"

Wrap all the views present inside NestedScrollView into a RelativeLayout. For ex,
<androidx.core.widget.NestedScrollView
android:id="#+id/studentPreviewNSV"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginTop="90dp"
android:fillViewport="true"
android:visibility="gone"
app:layout_constraintTop_toTopOf="parent"
tools:visibility="visible">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- your remaining code -->
</androidx.constraintlayout.widget.ConstraintLayout>
</RelativeLayout>
</androidx.core.widget.NestedScrollView>

I managed to fix this problem by adding android:layout_marginBottom="100dp"
I think this was happening because I gave android:layout_marginTop="90dp" to my NestedScrollView and due to that RecyclerView was assuming that all the items are visible on the screen so there is no need for scrolling. (Correct me if I'm wrong)
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/reportRV"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/courseSpinner"
tools:listitem="#layout/report_list_layout"
android:orientation="vertical"
android:layout_marginBottom="100dp"/>

Textview over Imageview in a fixed position

I would like to put some textviews over an image in a fixed position.
I tried using relative, contraint and frame layout but what I see in preview does not match on my device.
I tried to use px, sp and dp but it did not help.
Textviews must stay exactly in their position on every device.
Thanks

you can try screen height programmatic to your textview according to your requirement for more detailing answer elaborate your question first.

If I were you, I would use a custom view in which I would simply calculate the necessary coordinates.

"ScrollView can only host 1 child" in 2 fragments with only 1 child?

I have 2 fragments, each with a ScrollView, and 1 ConstraintLayout inside. The ContraintLayout contains multiple children inside, but the ScrollViews only have 1 child. When I go to fragment 1, I recieve no error. I go to fragment 2, all good. When I return to fragment 1 however, I get the following error:

I had snackbars that attatched to items. They worked perfectly under some circumstances, but for some reason not always. I think this may have something to do with how Fragments are created and destroyed upon exit.
I replaced my snackbars with toasts, and it fixed the issue, although the appearance has been worsened.

ListView Scrollbar is not resizing

I went through different solutions from stackoverflow and web, but didn't work. the scrollbar of listView is very tiny, I want it to be large enough. I used android:scrollbarSize="55dip" but it didn't work, android ignores it.

Use this line too with the scrollsize you used:
