How can i add double ScrollView in XML? - android

I am currently trying to add a double ScrollView inside my XML.
I am using two different views in my layout - a list and categories.
When a user clicks on a category - the list of videos will become visible and the categories will become invisible.
Currently, the category buttons are scroll-able and when I click a category button, the list of videos does become visible. However, the issue is that the list of videos do not scroll.
Here is my layout code:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/tools"
android:orientation="vertical"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--this is parent layout where I call ListView-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/parent01"
android:descendantFocusability="beforeDescendants"
android:fitsSystemWindows="true"
android:focusableInTouchMode="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:orientation="vertical"
android:weightSum="1">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ListView
android:id="#+id/listview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="2dp"
android:layout_marginRight="5dp"
android:divider="#android:color/transparent"
android:dividerHeight="1dp"></ListView>
<ProgressBar
android:id="#+id/nextProgress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_gravity="center"
android:visibility="gone"
style="#android:style/Widget.DeviceDefault.Light.ProgressBar.Small"/>
</RelativeLayout>
</LinearLayout>
<!--This is the categories layout-->
<ScrollView
android:layout_width="wrap_content"
android:orientation="vertical"
android:id="#+id/ll_buttons"
android:layout_marginTop="60dp"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_height="200dp">
<Button
android:layout_weight="0.5"
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#drawable/rec_img"/>
<Button
android:layout_weight="0.5"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#drawable/rec_img"
android:id="#+id/button2"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_height="200dp">
<Button
android:layout_weight="0.5"
android:id="#+id/button3"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#drawable/rec_img"/>
<Button
android:layout_weight="0.5"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#drawable/rec_img"
android:id="#+id/button4"/>
</LinearLayout>
</ScrollView>
</RelativeLayout>

for nested scrolling better to use NestedScrollView
NestedScrollView as the name suggests is used when there is a need for a scrolling view inside another scrolling view.
ScrollView vs NestedScrollView
another thing use RecyclerView insted of Listview
RecyclerView vs. ListView
sample layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="wrap_content">
// add here all your controlls
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
and dont forgot to set setNestedScrollingEnabled() property in RecyclerView like below code
If this property is set to true the view will be permitted to initiate nested scrolling operations with a compatible parent view in the current hierarchy. If this view does not implement nested scrolling this will have no effect. Disabling nested scrolling while a nested scroll is in progress has the effect of stopping the nested scroll.
mRecyclerView.setNestedScrollingEnabled(false);

use nested scroll views
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.widget.NestedScrollView>

How can I add two Scroll views in a xml layout such that each scrollview take half of the height of the layout?

How do I add two ScrollViews in an android XML-layout such that each scroll view takes half of the height of the layout?
You can use LinearLayout as rootview then add two ScrollView as child and assign android:layout_weight="1" to both ScrollView
Note : if you want your view scroll horizontally then use HorizontalScrollView
SAMPLE CODE
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#android:color/black"
android:layout_weight="1">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--add viw here-->
</LinearLayout>
</ScrollView>
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#android:color/holo_red_dark"
android:layout_weight="1">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--add viw here-->
</LinearLayout>
</ScrollView>
</LinearLayout>
OUTPUT
There is a multiple way to do this. I am suggesting you one simple way.
try to add weightsum =2 inside parent layout. And devide layout with 1 like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_rel"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:weightSum="2.0" >
<RelativeLayout
android:id="#+id/child_one"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1.0"
android:background="#0000FF" >
</RelativeLayout>
<RelativeLayout
android:id="#+id/child_two"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1.0"
android:background="#00FF00" >

How make put ViewPager inside ScrollView and scroll all view as one part?

I have an activity that have viewpager inside scrollview like the follwoing
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!--someViews-->
</LinearLayout>
<!--then viewPager-->
<androidx.viewpager.widget.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</ScrollView>
Then the view pager holds some fragments which have a tall view too.
The problem is the scroll view not scrolling because of the view is not need to scroll but the view inside the viewpager fragment's not scrolling
so, Is it possible to make the whole view including the inside view pager scroll as one view?
What I am saying that I don't need to scroll the viewpager fragment as separated part I need to scroll it as part of activity view.
Thanks
I believe the setup you are looking for would work inside a CoordinatorLayout using the NestedScrollView widget like so:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout
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">
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Display1" />
<TextView
android:id="#+id/subTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/subtitle"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Body1" />
<androidx.viewpager.widget.ViewPager
android:id="#+id/viewPager"
android:layout_width="match_parent"
android:layout_height="300dp" />
</LinearLayout>
</androidx.core.widget.NestedScrollView>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
I have just tested this with a sample project with a single text view in a Fragment and I was able to both scroll the view and swipe through the pages.
Please note though: I did have to provide a specific height for the ViewPager in order for it to display.

Render a scroll view and list view on the same screen

I'm having issue with rendering a scroll view, below which I want a list view.
I want a scroll view, inside which I will add image views and text views or may be other UI elements.
Below this scroll view, I want a list view.
But when I do this, either the list view and scroll view overlap, or only the scroll view is rendered.

Its always an issue to have multiple scroll based views in the same layout. You can use a nested scrollview which is part of the V4 library.
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.v4.widget.NestedScrollView>
For more on layout_behaviour and nested scroll.
Change the Relative layout to Linear layout will solve this issue..!!

NestedScrollview inside a Recycler view not scrolling

I am creating an Android program. In this program, I have a ScrollView inside of which there is a RecyclerView. I am adding data in this RecyclerView via a RecyclerViewAdapter.
For each item of the RecyclerView, there is a NestedScrollview having a single LinearLayout of vertical orientation. I am dynamically adding ImageView in this LinearLayout.
The problem is that the images are not scrolling. In very rare scenarios (by tapping so many times on screen), it got scrolled for once.
Could anybody help me on this?
Here is the code -
Parent Recycler View :-
<ScrollView
android:id="#+id/scroll_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<android.support.v7.widget.RecyclerView
android:id="#+id/id_recyclerview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="#color/gray3"
android:dividerHeight="5sp"
android:paddingLeft="2sp"
android:paddingTop="5sp"
android:paddingRight="2sp"/>
<com.app.sh.widget.WrappedGridView
android:id="#+id/gridView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/White"
android:numColumns="2">
</com.app.socialhand.widget.WrappedGridView>
</LinearLayout>
</ScrollView>
And the Item of the Recycler View :-
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/vScrollView"
android:layout_below="#id/iv_up"
android:layout_above="#+id/iv_down"
android:isScrollContainer="true"
>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/ll_123"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
</LinearLayout>
</RelativeLayout>
</android.support.v4.widget.NestedScrollView>
I am dynamically adding the ImageViews in ll_123.
Try to use NestedScrollView instead of ScrollView or remove it. RecyclerView has own scrollview which will conflict with ScrollView.
You can try a structure like:
<ScrollView>
<NestedScrollView>
<LinearLayout>
<RecyclerView/>
</LinearLayout>
</NestedScrollView>
</ScrollView>
And ListItem layout should contain:
<NestedScrollView>
<LinearLayout/>
</NestedScrollView>
Check if this works correctly...
I got simmilar problem and this helped me:
<ScrollView
android:id="#+id/messages_scroll"
