Limit height of ListView on Android
I had this exact issue and to solve it I created two seperate LinearLayouts
to house the ListView
and Button
respectively. From there I put both in another Linear Layout
and set that container's android:orientation
to vertical
. I also set the weight of the the LinearLayout
that housed the ListView
to 0.1
but I dont know if that has any effect. From there, you can set the height of the bottom container (that has your button) to whatever height you would like.
EDIT this is what i mean:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.1"
android:orientation="horizontal">
<ListView
android:id="@+id/ListView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:dividerHeight="2px"></ListView>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="45px"
android:background="@drawable/drawable"
android:orientation="horizontal">
<Button
android:id="@+id/moreButton"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:background="@drawable/btn_more2"
android:paddingRight="20px" />
</LinearLayout>
The above solution will fix the button the the bottom of the screen.
To have the button float at the bottom of the list, change the height of ListView01
to wrap_content
:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.1"
android:orientation="horizontal">
<ListView
android:id="@+id/ListView01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:dividerHeight="2px"></ListView>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="45px"
android:background="@drawable/drawable"
android:orientation="horizontal">
<Button
android:id="@+id/moreButton"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:background="@drawable/btn_more2"
android:paddingRight="20px" />
</LinearLayout>

How to limit the height of a ListView within a GridLayout?
This answer extends my comments to the question and attempts to explain why this cannot be done with XML via GridLayout's attributes
.
Adding GridLayout
to the framework allowed solving a range of drawbacks regarding nested layouts, one of wich was "inability to control alignment along both horizontal and vertical axes simultaneously"
as described in the article New Layout Widgets: Space and GridLayout by Philip Milne.
This alignment control is performed by layout_gravity
parameter whose description
states that the parameter "specifies how a component should be placed
in its group of cells",
(NOT within a root layout
). Basically, it's the same as that of LinearLayout
, which also mentioned in the article: "Alignment/gravity also works just like gravity in LinearLayout..."
And as we know, for LinearLayouts
, once a view has taken the whole height of the screen (like ListView
in your case), the views below it go behind the screen if the layout oriention was set to "vertical"
.
If we look at the GridLayout.LayoutParams documentation we won't find any parameter which would allow a component within a cell group to stick to a certain position of the parent layout and stay at the position independent of the size of other components within the same group; similar to the layout_align[...]
parameters of a RelativeLayout.
My best guess about the absence of this kind of parameters in GridLayout
is better alignment control compare to nested layouts.
I'm sure you know a solution(s) for your problem using an approach other than GridLayout's
attributes. I'll just suggest one to make the answer look accomplished:
<GridLayout
... >
<RelativeLayout
... >
<TextView
...
android:id="@+id/tv"
android:layout_alignParentBottom="true" />
<ListView
...
android:layout_above="@id/tv">
</ListView>
</RelativeLayout>
</GridLayout>
Does ListView has a size limit?
The listview is virtualized so it has practically no size limit. So you dont have any limit to add the number of elements in it.
