I have problem in this layout that : it doesn't show any child after the listView
and the listview is filling this sight ; it scrolls but didn't show the any other child
I have tried to user ScrollView but it make issues with expandlist
this is layout xml code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/select_bg"
android:orientation="vertical" >
<TextView
android:id="#+id/Header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/header_bg"
android:gravity="center"
android:paddingRight="50dip"
android:paddingTop="5dip"
android:text="#string/select"
android:textColor="#60240a"
android:textSize="18dip"
android:textStyle="bold" >
</TextView>
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#android:color/transparent"
android:divider="#drawable/line_divider"
android:dividerHeight="3dip"
android:listSelector="#android:color/transparent" >
</ListView>
<ImageView
android:layout_width="fill_parent"
android:layout_height="3dip"
android:src="#drawable/line_divider" />
<ExpandableListView
android:id="#+id/expandableList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#android:color/transparent"
android:childDivider="#drawable/line_divider"
android:divider="#drawable/line_divider"
android:dividerHeight="2dip"
android:listSelector="#android:color/transparent"
android:textColor="#60240a" >
</ExpandableListView>
</LinearLayout>
When you are using ListView in the layout you have to add this property android:layout_weight for the listview. Without this property being set, you cannot get all views.
Since your layout is linear any views that exceeds the limit of the screen are not displayed in the screen. Yes scrollview makes issues with list or expandable listview as the scrollview itself is scrollable it will consume the scrolls of listview and expandablelist. To resolve this you have to re order or change your layouts to make your rest of the views visible
Give the first ListView some constant height. Like
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="300dip"
....
/>
LinearLayout will not scroll when its content increases. And you cannot use a ScrollView as parent for ListView.
Set all layout_height - attributes from direct childs of your root layout to fill_parent.
Than give every of these layouts a attribute layout_weight.
The value of layout_weight is an integer according to how many space they've been granted in the view.
For example two views: one with weight 2 and one with weight 1: The weight 1 is twice the size of weight 2.
Just play a little with the weight attribute to find out for yourself.
You have given height of listview as wrap_content so it will occupy the all the space in screen so u give the height of listview fixed and same thing applied to expandable list also give fix height to that also.
Hope u get it All The best

My XML file has a LinearLayout containing two ListView with android:height="wrap_content". However, when one of the ListView has too much contents, it pushes another ListView and eat up its space. What can I do to make it stops pushing at certain height? I've tried adding layout-weight or maxHeight but it doesn't help.
If you want the same amount for both ListViews equally divided, just put them in a LinearLayout.
LinearLayout will have property weightSum=2 while both ListViews will have, depending on the LinearLayout orientation property:
If vertical -> both ListViews will have android:height="0dp" and layout-weight=1
If horizontal -> both ListViews will have android:width="0dp" and layout-weight=1
I solved it by doing it programmatically. It seems XML doesn't give much control for dynamic height. I added onLayoutChangedListener to both ListView to detect height change and add height control logic in the listener.
Try this :
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/green_bg_duplicate"
android:gravity="center"
android:orientation="vertical"
android:weightSum="2">
<RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1" />
<RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1" />
</LinearLayout>
So I am developing a screen where there are some images and buttons on top and Below that is a list view which shows a list of some activity.
The design is something like this :-
Now on smaller screen the ListView height becomes very small as the screen space is taken up by the above icons and images.
So how can i increase the height of the Linearlayout or ListView so that user can scroll to the see the rest of the ListView.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
.... Other Layouts .....
<ListView
android:id="#+id/listArea"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:paddingLeft="#dimen/list_padding"
android:paddingRight="#dimen/list_padding" />
</LinearLayout>
Edit: Tried using the top view as a header to the List but since I want an EmptyView too, this is creating a problem as it replaces the whole header + listview
From what I read about that issue, you should specify the Views on top as header of the list, and the'll scroll properly.
Afaik this only works if the list is non-empty, as the empty view replaces the whole list including headers.
You can use the weightSum and layout_weight attributes to control how much of the parent's available space a child view will take up. To use these, a parent layout, for example, your LinearLayout, gets the android:weightSum attribute. Each child layout gets the android:layout_weight attribute, where the sum of all child weights is the weightSum of the parent. In addition, each child should have their layout_height or layout_width set to 0dp, whichever is going to be decided by the weight.
Here's an example based on your diagram. Let's say you want the two top views to take up 1/4 of the screen each, and the ListView to take up the bottom half. Add android:weightSum="4" to your LinearLayout, android:layout_weight="1" to the two child layouts that you represent with ...Other Layouts..., and android:layout_weight="2" to the ListView. Code might look something like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="4">
<ImageView
android:layout_weight="1"
android:layout_height="0dp"
...some other attributes.../>
<LinearLayout
android:layout_weight="1"
android:layout_height="0dp"
android:orientation="horizontal"
...some other attributes...>
...some children of the LinearLayout...
</LinearLayout>
<ListView
android:id="#+id/listArea"
android:layout_width="match_parent"
android:layout_height="0dp"
android:paddingLeft="#dimen/list_padding"
android:paddingRight="#dimen/list_padding"
android:layout_weight="2"/>
</LinearLayout>
So I'm trying to create a screen which has a ListView and over that I need to be able to float another custom horizontal ListView, right at the bottom edge of the screen. When the user scrolls on the vertical listview, the horizontal one would go invisible and reappear when the scrolling stops. I figured FrameLayout would be my best bet for overlapping views. But I can't seem to make this work. The Horizontal listview seems to occupy the whole screen space. Any ideas? Is this even the right approach? I wish to have something similar to a fixed div in HTML.
Here's my XML:
UPDATE-1: Used RelativeLayout as suggested, but still a no-go. The HorizontalListView still seems to be occupying the whole screen. I'm using the HorizintalListView from here
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<ListView
android:id="#+id/messages"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="5dip" />
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<test.ui.app.HorizontalListView
android:id="#+id/folders"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF" />
</RelativeLayout>
</RelativeLayout>
I got it to work by setting the height of the inner Relative Layout myself instead of using 'wrap_content'.
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<ListView
android:id="#+id/messages"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="80dip"
android:layout_alignParentBottom="true" >
<test.ui.app.HorizontalListView
android:id="#+id/folders"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF" />
</RelativeLayout>
</RelativeLayout>
You cannot adjust the views inaide FrameLayout.So it will be better for you to go for RelativeLayout.
Or you can put your listviews inside RelativeLayout or linearlayout and then you can adjust.
Hope this will help you. :)
Like the other answerer said, you could use a RelativeLayout:
set android:layout_alignParentLeft|Right|Top|Bottom="true" for the vertical list view
set android:layout_alignParentLeft|Right|Bottom="true" for the horizontal list view (and height to "wrap_content" or fixed size)
Or if you reeeeaaaally want to stick with FrameLayout (maybe for performance reasons...), you could somply add a huge android:layout_marginTop to the horizontal list view. But this solution is uglier, since you need to set exact values. For example if the whole screen is 320dp height, and you want the horizontal list view to be 80dp height, you need to set the top margin to 240dp. However if you run this on a screen with different aspect ratio, the horizontal list view will be ugly.
I have a main.xml with a LinearLayout with three items inside, LinearLayout, ListView and LinearLayout. I would like the ListView to be as big as possible while keeping the bottom LinearLayout always showing and not shrunk or knocked off the screen.
I have tried making the ListView height fillparent, but then the bottom LinearLayout doesn't show up, same with wrapcontent, since the ListView has lots of content.
When I make the ListView a set size, say 300dp, I have space below the bottom LinearLayout. I tried to fix this by making the top level LinearLayout gravity=fill, but that didn't help.
Also, depending on the android I try it on, the bottom LinearLayout will drop off the screen, or get shrunk.
In case it's relevant, the top level LinearLayout is set to fillparent for height.
My goal is to keep the top and bottom LinearLayout to wrap their content, and the middle ListView fill what's left... any suggestions?
Thanks in advance for your efforts!
I believe you can just add android:layout_weight="1" to the ListView, with the ListView set to a height of fill_parent, and the two LinearLayouts set to wrap_content. Regardless, I usually prefer to use a RelativeLayout. You can specify the header to align to the top of the screen, the footer to align to the bottom, and the ListView to fill the space in between, like so:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout
android:id="#+id/header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
>
//...insert stuff here
</LinearLayout>
<LinearLayout
android:id="#+id/footer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
>
//...insert stuff here
</LinearLayout>
<ListView
android:id="#+id/listview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/footer"
android:layout_below="#id/header"
/>
</RelativeLayout>
I am attempting to make a ListView inside a table consume all of the available vertical space minus the space needed for an EditText control.
I have set every attribute I can think of here to make it work:
<?xml version="1.0" encoding="utf-8"?>
<TableRow android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FF0000">
<ScrollView android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView android:id="#+id/conversation"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="false"/>
</ScrollView>
</TableRow>
<TableRow android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#00FF00">
<EditText android:id="#+id/messagetext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="text|textAutoCorrect|textMultiLine|textImeMultiLine"
android:imeOptions="actionDone"/>
</TableRow>
I must be missing something, as the result is a fully filled horizontal, but both the ListView and EditText appear to be behaving as if their attributes were wrap_content.
Is there a particular reason you're using a TableLayout? I'm not very familiar with using them yet, but what you're trying to accomplish is simple with a RelativeLayout. Also, you don't need to place the ListView within a ScrollView, the ListView handles scrolling on its own. Here is an example of how you could accomplish this using a RelativeLayout:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<EditText
android:id="#+id/message_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#00FF00"
android:inputType="text|textAutoCorrect|textMultiLine|textImeMultiLine"
android:imeOptions="actionDone"
android:alignParentBottom="true"
/>
<ListView
android:id="#+id/conversation"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FF0000"
android:layout_above="#id/message_text"
/>
</RelativeLayout>
This way, you first define the EditText to take up a certain amount of space (wrap_content, in this instance). Then, you define the ListView to fill the remaining space with fill_parent. Adding android:layout_above="#id/message_text" aligns the bottom edge of the ListView with the top edge of the EditText view.
I appear to have been missing an attribute android:layout_weight on the top TableRow. Evidently, anything over 2 makes it consume the rest of the vertical real estate. Can anybody explain why the special treatment for TableRows?
Don't use ListView inside of ScrollView, because ListView manages it's own vertical scrolling. Doing so will kill all optimization's done by the ListView
