Android ListView doesn't expand the whole screen? - android

I've the following Activity:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/FiltersLayout" android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent"
>
<ScrollView android:id="#+id/FiltersScroll"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<ExpandableListView android:id="#+id/featureList"
android:layout_width="fill_parent" android:stretchColumns="*" android:orientation="vertical" android:layout_height="fill_parent">
</ExpandableListView>
</ScrollView>
</LinearLayout>
I need the ExpandableListView to scratch the screen, but it shows as the following:
![Anzroiz ListView][1]

Try changing the height of the ScrollView to fill_parent, but really you should omit the ScrollView entirely as a ListView provides its own scrolling.

LinearLayout not scrolling with ScrollView

I have a LinearLayout that has a lot of TextViews programatically put in. By a lot, I mean it extends beyond the bottom of my screen. I want to use a ScrollView to allow the user to scroll beyond the screen and see the rest of the TextViews. This is my activity_main.xml currently:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:id="#+id/ll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="61dp"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
Any help will be greatly appreciated! Thanks!
Try changing android:layout_width="wrap_content" to android:layout_width="match_parent"
<LinearLayout
android:id="#+id/ll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="61dp"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
Change your code as below !
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/ll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="61dp"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
NOTE: To see if it is scrolling or not try placing some views inside linearLayout like buttons otherwise you won't notice the screen scrolling
Also You Can Do Like This.It Works Well.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollData"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="vertical" >
<LinearLayout
android:id="#+id/linearWhere"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:orientation="vertical"
android:padding="5dp">
</LinearLayout>
</ScrollView>

How to show other views after list view height set to fill_parent

To prevent multiple GetView calling I have set the height of ListView to fill_parent.
How to show other views than the ListView itself?
The following layout is inflated in a ViewPager:
<?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"
android:padding="15dp" >
<ListView android:id="#+id/lv_viol_infraction"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<include layout="#layout/activity_prontuario_home" />
</LinearLayout>
where the included layout is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="20dp" >
<ScrollView
android:id="#+id/prontuariohome_scrollview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="none" >
.
.
.
.
</ScrollView>
</LinearLayout>
EDIT: This solution won't work for view higher than a button
I don't understand what you want to achieve, but if you NEED to have the height as fill_parent for some reason and can't be any other value, you can put the ListView with inside a LinearLayout with the height="0dp" and weight="1". So would be something like 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="vertical"
android:padding="15dp" >
<LinearLayout android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="vertical" >
<ListView android:id="#+id/lv_viol_infraction"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
<include layout="#layout/activity_prontuario_home" />
</LinearLayout>
Try to use following code
android:layout_height="0dp"
android:layout_weight="1"
in ListView tag
With android:layout_height="0dip" the view will take the rest of the free place
You said this solution is wont work:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView android:id="#+id/lv"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white" android:layout_above="#+id/bt"/>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/bt" android:layout_alignParentBottom="true"/>
just add it a android:layout_above="#+id/bt" to listview.
I'm sorry for being not clear.
Here is the link of the (probably) main thread asked here in Sof about the issue I was talking about.
After some tries I'm happy to give you the solution of my problem.
Giving another layout above the ListView lets the LV cuts the space not filled by the ListView itself
<?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"
android:padding="15dp" >
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ListView android:id="#+id/lv_viol_infraction"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
<include layout="#layout/activity_prontuario_home" />
</LinearLayout>

Android ListView doesn't expand the whole screen

I've problem similar to the one here: Android ListView doesn't expand the whole screen?
The XML is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/ResultLayout">
<ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent">
<ListView android:layout_width="fill_parent" android:id="#+id/ListView"
android:layout_height="fill_parent"></ListView>
</ScrollView>
<LinearLayout android:id="#+id/pagingPanel"
android:gravity="center" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="horizontal"></LinearLayout>
<Spinner android:layout_width="fill_parent" android:id="#+id/ManSpinner"
android:layout_height="fill_parent" />
</LinearLayout>
In this case, I should have a ScrollView or the PagingPanel LinearLayout will disappear.
Edit
The desired layout is to have all the elements stacked on top of each other. but if the elements exceed the page height, a scroll should be added to the ListView.
If you have a vertical LinearLayout, You can't have multiple fill_parent for layout_height of your LinearLayout elements. What layout you would like to achieve? Uniformly divide screen for all elements?
Another problem is that using ListView in ScrollView is not a good idea also because ListView itself is scrollable.
You should write what layout you would like to achieve with your XML. Also generally is a good practice to write your XML in multiple steps and iterate to woking solution layout by layout.
EDIT: Ok, try something like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/ResultLayout">
<ListView android:id="#+id/ListView"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<LinearLayout android:id="#+id/pagingPanel"
android:gravity="center"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
</LinearLayout>
<Spinner android:id="#+id/ManSpinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>

Android UI difficulties

My layout was perfect until I decided to add a scrollview.
<?xml version="1.0" encoding="utf-8"?>
<TableLayout android:id="#+id/tableLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<ScrollView android:id="#+id/scrollView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:id="#+id/linearLayout1">
<TableLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:id="#+id/tableLayout1"/>
</LinearLayout>
</ScrollView>
<Button android:layout_width="match_parent" android:id="#+id/button1" android:text="Start" android:layout_height="50dip" android:onClick="getOutput"></Button>
</TableLayout>
I would like the button to stay at the bottom of the screen, I would actually like the scrollview to take up the entire screen. With just the inner table layout it works fine. In the Graphical Layout preview it looks how I want it, but not when I run it.
I would like the scrollview to take up the whole screen except the button, which I'd like to be at the bottom.
you could use RelativeLayout or LinearLayout as Root view. Giving Button more weight. That way ScrollView won't take up the whole thing.
this should work
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<ScrollView android:layout_width="fill_parent" android:layout_height="0dip"
android:layout_weight="1.0">
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="vertical"
android:id="#+id/linearLayout1">
<TableLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/tableLayout1"/>
</LinearLayout>
</ScrollView>
<Button android:layout_width="fill_parent" android:layout_height="wrap_content"
android:text="Bottom Button"/>
</LinearLayout>
Try setting ScrollView fillViewport attribute to true.

ScrollView Not Responding

I have the following XML and am not doing anything fancy with overriding scrolling behaviors:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ScrollView
android:id="#+id/myscrollview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true"
android:layout_weight="1">
<ListView
android:id="#+id/mylistview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</ScrollView>
<TextView
android:id="#+id/my_empty"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="#string/my_foo"
android:gravity="center"
android:visibility="gone"
/>
</LinearLayout>
However, while the embedded listview does respond to presses and long presses, it does not scroll. What am I doing wrong?
The trailing TextView is the listview's emptyview.
ScrollView does not play nicely with any other view that scrolls natively, i.e WebView, ListView, etc.
Try a Relative layout and see if this does what you need.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#+id/mylistview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alingParentTop="true"
/>
<TextView
android:id="#+id/my_empty"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/my_foo"
android:gravity="center"
android:visibility="gone"
android:layout_alignParentBottom="true"
/>
</RelativeLayout>
In android it should not put ListView inside a ScrollView. It will not work.
Take the ListView out of the ScrollView. It causes problems, and is unnecessary (ListView handles scrolling on its own.)
