In Android, I'm trying to basically create a table with 2 rows, where 1 row is say 10 pixels, and the other takes the rest of the screen. In silverlight, this is equivalent of a table with 2 rows, one on "Auto" and the other set to "*".
Is there any way to do this? I have been playing with the layout weight, but this is always a percentage, and I would like 1 row to be fixed size (wrap_content basically).
Any ideas?
edit:
I tried what was suggested, but it'snot working.. So I want the first row to take up the entire space, except what row 2 took up. Row 2 consists of 2 buttons side by side, Row 1 is just a ListView. Here is what I have:
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:layout_weight="1" android:background="#FF0000">
<ListView android:id="#+id/edit_group_listView"
android:layout_width="fill_parent" android:layout_height="fill_parent" />
</LinearLayout>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:layout_weight="0" android:background="#FFFF00">
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="50dip" android:stretchColumns="2">
<TableRow>
<Button android:text="#string/button_save" android:id="#+id/edit_group_save"
android:layout_width="150dip" android:layout_height="50dip"
android:enabled="false" android:layout_column="1"></Button>
<Button android:text="#string/button_cancel" android:id="#+id/edit_group_cancel"
android:layout_width="150dip" android:layout_height="50dip"
android:layout_column="3"></Button>
</TableRow>
</TableLayout>
</LinearLayout>
When I view this all I see is the yellow linearlayout (the buttons), no listview at all. The listview has 50 items, and I can confirm it's visible by taking it out of this setup.
Yep, easy actually.
First cell must have the weight of 0. Second cell must have the weight of 1 and fill the parent by width. That way it will take up the remaning space within the container it's in.
Easy! Here's an example for your convenience
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout android:orientation="vertical" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="0" android:background="#FF0000">
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="SomeText" android:id="#+id/theview"/>
</LinearLayout>
<LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:background="#FFFF00">
</LinearLayout>
</LinearLayout>
=======================================
UPDATE
Mate you overcomplicated it like Crayze!
First. You don't need a table layout for that.
Second the problem is you set both heights of the layout to fill_parrent. So they are both fighting over for the screen size. To fix this you just have to set both the layout sizes to wrap_content. That will work just fine. Here have an example, without the table on your code.
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:layout_weight="1" android:background="#FF0000">
<ListView android:id="#+id/edit_group_listView"
android:layout_width="fill_parent" android:layout_height="fill_parent" />
</LinearLayout>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="0" android:background="#FFFF00">
<Button android:text="#string/button_save" android:id="#+id/edit_group_save"
android:layout_width="150dip" android:layout_height="50dip"
android:enabled="false" android:layout_column="1"></Button>
<Button android:text="#string/button_cancel" android:id="#+id/edit_group_cancel"
android:layout_width="150dip" android:layout_height="50dip"
android:layout_column="3"></Button>
</LinearLayout>
Use layout weight and set the fixed one to be 0, and the other one to be any number.
Okay so actually I figured this out by reviewing what Taranasus wrote, which was accurate to a degree.
This is the final XML that worked:
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:layout_weight="1" android:background="#FF0000">
<ListView android:id="#+id/edit_group_listView"
android:layout_width="fill_parent" android:layout_height="fill_parent" />
</LinearLayout>
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="0" android:background="#FFFF00">
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="50dip" android:stretchColumns="2">
<TableRow>
<Button android:text="#string/button_save" android:id="#+id/edit_group_save"
android:layout_width="150dip" android:layout_height="50dip"
android:enabled="false" android:layout_column="1"></Button>
<Button android:text="#string/button_cancel" android:id="#+id/edit_group_cancel"
android:layout_width="150dip" android:layout_height="50dip"
android:layout_column="3"></Button>
</TableRow>
</TableLayout>
</LinearLayout>
This site also helped: http://www.curious-creature.org/2009/02/22/android-layout-tricks-1/
The problems were that:
1. The orientation had to be "vertical", which actually doesn't make sense according to the docs.
2. The second row (the fixed one) has to have a height of wrap_content, which also doesn't make sense since Google docs about weight specifically say both elements should be fill_parent.

I would like to obtain this layout for an Android app for mobile phones:
Icon - Object1
List with entries related to Object1
Icon - Object2
List with entries related to Object2
So far I have used the following layout tree (edited graphically with the editor in Android Studio):
Root-LinearLayout
Vertical LinearLayout
Horizontal LinearLayout with icon and text
ListView
Vertical LinearLayout
Horizontal LinearLayout with icon and text
ListView
May be this is not the best way to organize such layout (may be I should use lists with header, but suggestions very welcome), however it can be a good case for understanding deeper how ListView works.
This is the graphical layout generated:
the blue row corresponds to the first LinearLayout. As you can see from the second screenshot that follows, the second list goes all the way down to Hell, bringing me with her. Is there any way to make the lists respect the wrap_content+ weight behaviour?
The XML code follows. I have tried several combos (both reasonable and unreasonable) of layout:weights but none works. I also tried to set the min-width of the first LinearLayout (the hidden one), but nothing changes.
Could you please help me?

It should work if you put your ListViews inside of the child LinearLayouts which hold the LinearLayout that has the TextView and ImageView. You also should be using "0dp" for the height when using weight with a vertical layout.
Something like this, I believe, should work
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:gravity="center_vertical"
android:minHeight="50dp"
android:layout_weight=".2">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView15"
android:src="#drawable/abc_ic_menu_share_mtrl_alpha" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Object1"
android:id="#+id/textView24"
android:textSize="26dp"
android:paddingLeft="10dp" />
</LinearLayout>
<ListView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:id="#+id/listView2"
android:layout_weight=".8" />
</LinearLayout>
Note the other changes: I gave the inner-LinearLayout an arbitrary weight of ".2" then the ListView a weight of ".8". And, of course, set the height to "0dp". You may need to play with those weights a bit but I think doing something like that for both first child LinearLayouts should get you close.
That may get your current layout to work but using headers and/or an ExpandableListView may be a better option.
I would like to have a layout which is similar to
Kinda feel guilty because I recently just asked a question about layouts but I had no idea that I needed to do this(nor did I know it was this hard), I have researched into View Layouts and I've tried use layout.toRightOf etc etc. I have the left/right arrows, I just need to add the up and down buttons
<?xml version="1.0" encoding="utf-8"?>

So essentially, just some insight on how I could add the up and down buttons within the same layout as to avoid layouts drawn onto my activity and overlapping
It seems that all your button images have the same height, so why not just use a TableLayout?
Keep the top-left and top-right cells empty, and in the other cells put your buttons.
Code (ommitting variables):
<TableLayout>
<TableRow>
<View />
<Button>...</Button>
<View />
</TableRow>
<TableRow>
<Button>...</Button>
<Button>...</Button>
<Button>...</Button>
</TableRow>
</TableLayout>
I have a linear layout with just a single TableLayout in it.
The Table Layout further has two rows with two columns each.
First Table Row has two Images.
Second Table Rows has two buttons.
But this does not show up on the complete screen, rather only shows on the first half or maybe depends on the image height. Both the images are actually same file, but shown with different Widths.
Help please...

I am showing data from DB in an Activity. I want a Table and buttons on bottom. For data thought TableLayout would be best option for it. I added TableLayout to HorizontalView & to ScrollView making it scroll vertically & Horizontally. Am adding all rows dynamically - including header. This part is working fine.
I want is when the contents is less than the screen width, it should yet occupy the whole screen width. For eg. If a table fits well in Portrait mode then ofcourse for Landscape mode their will be blank space left on the right. I don't want that space to eb empty, instead to occupy by all columns. If the row width is greater than the screen width then no issues at all - as horiontal scrollbar appears.
I tried few variations, but nothing helped out. Any idea what settings to make to utlize all space (if at all avbl) & show it.
And yes, 1 more issue of horizontal scrollbar, it appears just on the last row. I want it to
appear below last row - so the border of last row is visible. My XML :
<?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:scrollbars="horizontal|vertical">

android:layout_height="wrap_content" android:layout_marginBottom="20dp"

</TableLayout>
</HorizontalScrollView>

android:layout_marginTop="15dp">
<Button android:id="#+id/browseAddBtn" android:text="Add" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:layout_marginRight="10dp" />
<Button android:id="#+id/browseViewBtn" android:text="Edit" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:layout_marginRight="10dp" />
<Button android:id="#+id/browseReturnBtn" android:text="Return" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" />
</LinearLayout>
</LinearLayout>
OUTPUT :
I found one thing while solving your problem, about TableLayout when used inside a HorizontalScrollView. The android:stretchColumns is not working when we use Table Layout inside Horizontal Scroll View. So that you are getting blank space when screen is rotated or columns have less width data.
I hope you understand this. I am trying to solve this problem by replacing Horizontal Scroll View with some other. I will post answer if i get solution. Bye.
EDIT
Hi Tvd finally I got the solution for your problem. make below changes to your XML layout file.
In <HorizontalScrollView>
use
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
Use stretchColumns = "*" in TableLayout if you want all columns to be stretched.
Bye. :-)

Unfortunately, it seems to want to fit all the columns into the space that the button occupies, as opposed to the width of the screen. Or maybe there is another constraint that I do not understand. I'd appreciate your help.

I think I forgot this property for the TableLayout element:
android:stretchColumns="0"
It appears to be working now.
I don't see anything obviously wrong in what you are showing there. To get a better picture of what is going on, you might try out the heirarchy viewer. It comes with the SDK. It will visualize for you how much space each of the "hidden" layers is taking, so you can figure out which one decided to only be that big.
