How to make a linearlayout filling remaining space in a relativelayout? - android

I've got a relativelayout with three linearlayouts as children. The last one has a fixed height and has android:layout_alignParentBottom set to "true". While the middle one is properly positioned below the first one, it goes as far as the bottom of the screen, so that its lower part is overlapped by the third one.
What's wrong?
Thanks

You could try using layout weights to control the relative sizes of the child layouts. There is an article on my blog which gives some information on the use of layout weights.
As an example, try this:
<?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" >
<LinearLayout
android:id="#+id/category"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:orientation="horizontal" >
<ImageView
android:id="#+id/back_btn"
android:layout_width="29dp"
android:layout_height="34dp"
android:layout_gravity="center_vertical" />
<TextView
android:id="#+id/cat_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity="center"
android:textSize="20sp" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/category"
android:layout_marginTop="10dp"
android:layout_weight="1"
android:orientation="horizontal" >
<ListView
android:id="#+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white"
android:cacheColorHint="#android:color/white" />
<TextView
android:id="#+id/android:empty"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white"
android:cacheColorHint="#android:color/white"
android:padding="10dp"
android:text="no_item" />
</LinearLayout>
<LinearLayout
android:id="#+id/nav_bar"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:orientation="horizontal" >
//stuff
</LinearLayout>
</LinearLayout>
The RelativeLayout has been replaced by a LinearLayout, all of the relative positioning tags have been removed, and a layout_weight attribute has been added to the centre LinearLayout which will cause it to stretch to fill the available space.


Nooo... the solution is much simpler! You forgot to say that you wanted the second linear layout to be above the third one :) Yes, the second linear layout must have BOTH android:layout_below="#+id/category" and android:layout_above="#+id/nav_bar". I tested it and it works.
But of course, you can use weights to achieve the same results, it is just going to be harder...
Here is your XML with the change I mentioned (tested it in eclipse):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/category"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_alignParentTop="true"
android:orientation="horizontal" >
<ImageView
android:id="#+id/back_btn"
android:layout_width="29dp"
android:layout_height="34dp"
android:layout_gravity="center_vertical"
android:src="#drawable/red_arrow_left" />
<TextView
android:id="#+id/cat_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity="center"
android:textSize="20sp" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/nav_bar"
android:layout_below="#+id/category"
android:layout_marginTop="10dp"
android:orientation="horizontal" >
<ListView
android:id="#+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white"
android:cacheColorHint="#android:color/white" />
<TextView
android:id="#+id/android:empty"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white"
android:cacheColorHint="#android:color/white"
android:padding="10dp"
android:text="#string/no_item" />
</LinearLayout>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/nav_bar"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:layout_alignParentBottom="true"
android:orientation="horizontal" >
//stuff
</LinearLayout>
</RelativeLayout>


You should add an id to your second LinearLayout
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/category"
android:layout_marginTop="10dp"
android:id="#+id/YOUR_ID">
and in the third layout add android:layout_below="#id/YOUR_ID"
<LinearLayout
android:id="#+id/nav_bar"
android:layout_below="#id/YOUR_ID"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:layout_alignParentBottom="true">

Sorry, i cant share image due to less reputation

you shouldn't be using wrap_content for your listview. you probably should change something about your layout. Perhaps use weight to get the desired size, like suggested here: https://stackoverflow.com/a/7588931/4498224
and here https://stackoverflow.com/a/11295287/4498224
If you don't want your list to scroll at all, you probably shouldn't be using a list. Maybe try to use a linearlayout and fill it in in your code.

this is the o/p which i am getting from the above linear layout i want the same using relative layout that support all the devices.

I think in Relative Layout you can't use weight but you can achieve this design can you make your question clear. What your finding difficult in designing this layout? Relative layout would be better if you go for different screen size

I try to align the last LinearLayout on top of the layout which holds the ListView by using this tag: android:layout_alignTop="#+id/app" But it doesn't seem to work. How can accomplish this?
Many Thanks!

Without any content a Layout with layout_width="wrap_content" and layout_height="wrap_content" is not shown as its width and height have a value of 0! Even if you have set some background color nothing will appear! You either have to add some content to the layout or you have to define another layout dimension. The position of your layout with android:layout_alignTop="#+id/app" should be correct. Hope that helps.

You can set "layout_below" on the first layout targeting to the last layout.
The code is that, I put a button inside the top layout as an exemple (Obs: In your listview you should use 0dp in layout_weight cause you already use layout_weight ^^) :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

Android LinearLayouts conflicting with each other

I have two LinearLayout
One contains a EditText with a patch9 image as a speech bubble and another with a TextView and ImageView
When I try typing into the EditText is begins to expand towards the right hand side then starts to reduce the width of the second LinearLayout (crushing the image)
XML 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:background="#color/white"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"

<EditText

android:layout_width="fill_parent"
android:layout_height="fill_parent"

</LinearLayout>
<LinearLayout

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingLeft="10dp" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
Looks like this
Any ideas?

its expanding since you have specified that layout_width of your LinearLayout should be "wrap_content", you should specify a fixed dimension with dps so it doesn't expand beyond.
Alternative use the weight tag
try out this modification:
<?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:background="#color/white"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal"
android:layout_weight="0.7">
<EditText
android:id="#+id/summaryMessage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/greeting_bubble_white"
android:gravity="center" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.3"
android:gravity="right"
android:orientation="vertical" >
<ImageView
android:id="#+id/summaryImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/picture_frame" />
<TextView
android:id="#+id/summaryText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingLeft="10dp" />
</LinearLayout>
however I would suggest more that you use this one:
<?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:background="#color/white"
android:gravity="center"
android:orientation="horizontal" >
<EditText
android:id="#+id/summaryMessage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.7"
android:background="#drawable/greeting_bubble_white"
android:gravity="center" />
<TextView
android:id="#+id/summaryText"
android:layout_weight="0.3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingLeft="10dp" />
</LinearLayout>
and that you use compound drawables on your summaryText here is a link that should help you: Using Compund Drawables

Use a relative layout, the layout editor is in fact pretty good so use it to position your views

Anybody can tell advise?
Please help.

Try containing the whole set in a RelativeLayout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/top_linear_layout_id"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" >
</LinearLayout>
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/bottom_linear_layout_id"
android:layout_below="#id/top_linear_layout_id" />
<LinearLayout
android:id="#+id/bottom_linear_layout_id"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
</LinearLayout>
</RelativeLayout>
Edited with sizing stuff.

Here's what you're looking for. Estel's on the right track with the RelativeLayout (although it can be done with a LinearLayout, I think the RelativeLayout approach is cleaner, though) but the layout is out of order Nevermind, check Estel's comment which proved me wrong. :) You should first define your header, align it to the top; next, define your footer, and align it to the bottom; finally, declare your ListView, give it a height of fill_parent, and set it to layout above the footer and below the header:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout

The problem would be that you are defining both of them relative to the size of the content they contain, but if the combined content of both is bigger than the screen then one of them will have to overlap the other one, you would be better to define the layout_height using an absolute measurement in a linear layout

Thanks all for your advice and direction of RelativeLayout. I can fix it now.
I have to define the footer LinearLayout before the ListView, and define ListView as android:layout_alignParentTop="true" and android:layout_above="#id/footer"
<?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"
>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<TextView
android:textSize="12px"
android:text="something here"
android:layout_width="50px"
android:layout_height="wrap_content"
/>
<TextView
android:textSize="12px"
android:text="something here"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout
android:id="#+id/footer"
android:orientation="horizontal"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_alignParentBottom="true"
>
<TextView
android:layout_height="wrap_content"
android:layout_width="0dip"
android:layout_weight="1"
android:textSize="12px"
android:text="50%"
/>
<TextView
android:layout_height="wrap_content"
android:layout_width="0dip"
android:layout_weight="1"
android:textSize="12px"
android:text="50%"
/>
</LinearLayout>
<ListView
android:id="#+id/tablebody"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_above="#id/footer"
/>
</RelativeLayout>
</LinearLayout>

This will definitely solve your problem:
<?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">
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:textSize="12sp"
android:text="something here"
android:layout_width="50dp"
android:layout_height="wrap_content"/>
<TextView
android:textSize="12sp"
android:text="something here"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
</HorizontalScrollView>
<ListView
android:id="#+id/listbody"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:orientation="horizontal"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
<TextView
android:layout_height="wrap_content"
android:layout_width="0dip"
android:layout_weight="1"
android:textSize="12sp"
android:text="50%"/>
<TextView
android:layout_height="wrap_content"
android:layout_width="0dip"
android:layout_weight="1"
android:textSize="12sp"
android:text="50%"/>
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
