I am trying to scroll the listview inside one Linear Layout but it is not working as i want. I am attaching one image for the more explanation.
This is my Layout
<android.support.v7.widget.CardView

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:clickable="false"
app:cardBackgroundColor="#android:color/white"
app:cardElevation="2dp"
app:cardPreventCornerOverlap="false"
app:cardUseCompatPadding="false">
<ScrollView
android:layout_width="fill_parent"

android:layout_height="wrap_content" />
<ListView
android:id="#+id/list"

Image explanation
I know it s not the good approach to use the listview but i have to do this with this way.
Just remove the ScrollView from your xml code, Because ListView have their own Scroll doesn't require ScrollView.Then code will work as you want. Second List will be shown after showing every item of first ListView.
According to android docmentation
You should never use a ScrollView with a ListView, because ListView takes care of its own vertical scrolling. Most importantly, doing this defeats all of the important optimizations in ListView for dealing with large lists, since it effectively forces the ListView to display its entire list of items to fill up the infinite container supplied by ScrollView.
First you user card view as top parent it seem you will use it as child of list view as I guess , if my guessing is correct this not wise to use two list view as child.
Second In any case you want use two listview in same view , its recommended to separate between them with view (TextView , ... etc).
the solution
1- remove scroll as it useless.
2- add weight to your list view as wrap content in your case mean whole view.
3- recommend add view to separate between list.

I want to "scroll" my PDF-Viewer and Listview, together, but it does not work, I can only scroll my listView and the pdf-view separately
You can use android:isScrollContainer="true". It will indicate that the view is one of the set of scrollable containers in its window. For more read this https://developer.android.com/reference/android/view/View
Because list view has its own scroll view you can not add it inside another scroll view so you must use them isolated
<HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:fillViewport="true">
<ListView
android:id="#+id/attackslist"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ffffff" />
</HorizontalScrollView>
I put a ListView inside an HorizontalScrollView because its content is way too long to fit in the screen, but what i get is that the list looks like this (the background color is there to show where the list's childs stop)
while i want all the childs equally spaced in there until the end of the list, which i get if the ListView is not inside a scrollbar
My custom layout I use in the adapter looks like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:background="#ffffff"
android:layout_height="match_parent">
<TextView
android:id="#+id/Moves"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_gravity="fill"
android:layout_weight="1"
android:gravity="center"
android:text="Moves"
android:textSize="14dp" />
<TextView
android:id="#+id/Hitboxactive"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_gravity="fill"
android:layout_weight="1"
android:gravity="center"
android:text="Hitbox Active"
android:textSize="14dp" />
</LinearLayout>
How should I handle this situation? Can I change the values during runtime?
Should I use a different View?
Thanks
I am trying to show three different vertical sections in my Android layout on one screen, each taking up one third of the screen, one on the top, one in the middle, and one on the bottom. Each section has a TextView and a ListView, and the ListViews can scroll so that you can see all items, but the overall page does not move. I have tried putting each TextView and ListView in a LinearLayout and setting the height of each LinearLayout to one third the total height of the screen, but the first ListView just shows all the items in it, taking up most of the screen, and the other sections are pushed down. I also tried using layout_weights, but for some reason it did not work. (EDIT: Setting layout_weight="1" ended up working, I'm not sure what I did wrong the first time) How can I make this work, or is there a better way to go about this?
<LinearLayout
android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="horizontal" >
<ListView android:layout_width="0dp" android:layout_weight="1"
android:layout_height="match_parent" android:background="#FF0000"/>
<ListView android:layout_width="0dp" android:layout_weight="1"
android:layout_height="match_parent" android:background="#00FF00">
<ListView android:layout_width="0dp" android:layout_weight="1"
android:layout_height="match_parent" android:background="#0000FF">
</LinearLayout>
This will give you three equally wide columns: to make it rows, change the orientation to vertical and swap the values of layout_height and layout_width for each listview. If you need to add the TextViews, you'll have to make each listview in this code either a RelativeLayout LinearLayout or FrameLayout, using same width/height/weight and arranging the ListView and TextView inside to taste. To do this most efficiently, use a Framelayout and use a margin on the listview to offset it from the TextView. You can place the TextView relative to the ListView inside the FrameLayout by using the layout_gravity in the TextView.
Ie (swapping the first "column"):
<FrameLayout android:orientation="vertical" android:layout_width="0dp"
android:layout_weight="1" android:layout_height="match_parent"
android:background="#FF0000">
<TextView android:text="Column!" android:background="#3Eff0000"
android:layout_height="40dp" android:layout_width="match_parent">
<ListView android:layout_marginTop="48dp" android:layout_height="match_parent"
android:layout_width="match_parent" android:background="#8Aff0000"/>
</FrameLayout>
Use this:
<?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="horizontal"
android:weightSum="3">

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"

How to change the height of ExpandableListView when group is expanded/collapsed?
I want to change the height of ExpandableListView to fit the height of its content, so that the view will not scroll inside itself.
this is the layout for main activity.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"

tools:ignore="MergeRootFrame" />
and this is a layout for the fragment of the main activity.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:orientation="vertical"
android:visibility="gone">

Below is the actual layout.
ExpandableListView will scroll inside when it has too many contents.
I want to scroll whole screen. Not only scroll view, but with header.
I solved a similar issue putting everything into a Header. I was close to solving it the traditional ways (ie. nesting layouts, weights, ...) but I felt the solution was pretty dirty, requiring overriding methods such as onGroupClick etc... to disable the ExpandableListView's scroll, while the header thing was clean and worked flawlessly for me.
So if you want to try this approach, just put an ExpandableListView alone inside your fragment, and prepare the rest to be inserted as Header.
So in your fragment a full ExpandableListView:
<ExpandableListView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/category_list"
android:transcriptMode="normal">
</ExpandableListView>
Then create the layout expandable_header.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context="jp.foo.android.fragment.FooFragment"
android:background="#color/category_bg">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_centerHorizontal="true"
android:id="#+id/frameLayout">
<TextView
android:text="#string/subtitle_question_category"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/subtitle_category"
android:gravity="center_vertical|center_horizontal"
android:layout_gravity="center_horizontal|top"
android:textSize="20sp" />
</FrameLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/frameLayout"
android:background="#drawable/category_list_bg_shape"
android:layout_marginTop="0dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginBottom="10dp"
android:minHeight="300dp">
<LinearLayout
android:id="#+id/category_list_progressbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center_horizontal|center_vertical"
android:orientation="vertical"
android:visibility="gone">
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
</RelativeLayout>
And then inflate the header into the ExpandableListView:
.
.
.
View view = View.inflate(context, R.layout.expandable_header, null);
expandableList.addHeaderView(view, null, false);
.
.
.
This way the header will scroll together with the ExpandableListView, as it's inside it.
BTW, your layout has redundant elements, for example the FrameLayout that contains only a TextView. You can use only the TextView. Also the LinearLayout with the ProgressBar, if you are not using an opaque background, you could put the ProgressBar alone. The less ViewGroups you use the better the layout will perform!
I want my whole activity to scroll at once, but the ListView which is embedded in my ScrollView won't expand. I just see the first row, but I can scroll through the other rows, when scrolling the listView.
What I need is for the listView to expand in height so every items it contains are displayed without having to scroll the listview, only the main scrollView...
<ScrollView

<LinearLayout
android:id="#+id/header_Layout"
android:layout_width="match_parent"

...
</LinearLayout>
<TextView

android:layout_width="match_parent"
android:layout_height="wrap_content"

android:divider="#drawable/gradient_divider"
android:dividerHeight="1dp" />
</LinearLayout>
</ScrollView>
One of the main purposes of a ListView is to enable recycling of cells while scrolling. If you want all the cells to exist, then you don't need a ListView. Just use a vertically oriented LinearLayout.
