I have a listview that I'm populating with data and I'm trying to get my layout to look like this:
Is there a way to create this while using Linear or Relative layouts? I tried with TableRows and while it works, it leaves a gap between for the column that divides the left from the right and it doesn't look appealing at all.
Not too sure where to get started....any help is greatly appreciated.
I am writing a sample for one line. Please refer that.
<LinearLayout
android:id="#+id/line1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:text="Issue Number"
android:layout_weight="1.0"
android:layout_height="wrap_content"
android:layout_width="0px"
android:gravity="right"/>
<TextView
android:text="6046"
android:layout_weight="1.0"
android:layout_height="wrap_content"
android:layout_width="0px"
android:gravity="left"/>
</LinearLayout>
You need to write this for all the lines and then enclose it under the parent LinearLayout with orientation vertical.
You can provide an xml to format each row in a ListView, whereby each row is a simple horizontal LinearLayout with two TextViews.
So something along the same lines as this:

A more detailed article dealing with ListViews:
http://www.vogella.de/articles/AndroidListView/article.html
I created a layout with your firsts 2 rows:
<?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/linearLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:gravity="right"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Issue Number:"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Date Received:"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:layout_toRightOf="#+id/linearLayout1"
android:gravity="left"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="6,046"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="09/02/2008"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
</RelativeLayout>
You can actually do this by placing a 2 LinearLayout inside a single parent LinearLayout. Where parent android:orientation should be horizontal. For each row you need to use this technique.
I did use this method for my project.

I am designing a table using RelativeLayout in Android and add entries programmically. The result pleases me so far:
The layout code is
<RelativeLayout
android:id="#+id/table_relativelayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="#+id/column1_header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="#string/column1_header"
style="?android:attr/listSeparatorTextViewStyle"
android:layout_weight="1.0"
/>
<TextView
android:id="#+id/column2_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignBaseline="#id/column1_header"
android:text="#string/column1_header"
android:textSize="14sp"
android:textStyle="bold"
android:textAllCaps="true"
android:textColor="#color/textColor"
/>
<TextView
android:id="#+id/column3_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignBaseline="#id/column1_header"
android:text="#string/column3_header"
android:textSize="14sp"
android:textAllCaps="true"
android:textStyle="bold"
android:paddingRight="8dip"
/>
<TextView
android:id="#+id/example_column1_entry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#id/column1_header"
android:text=""
android:paddingLeft="8dip"
android:visibility="gone"
/>
<TextView
android:id="#+id/example_column2_entry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="#id/column2_header"
android:text=""
android:visibility="gone"
/>
<TextView
android:id="#+id/example_column3_entry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="#id/column3_header"
android:paddingRight="8dip"
android:text=""
android:visibility="gone"
/>
</RelativeLayout>
However, as more entries are added, scrolling becomes necessary. So I wrap the whole thing in a ScrollView (as per this answer)
<ScrollView
android:id="#+id/table_scrollview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fillViewport="true"
>
...
</ScrollView>
This of course has the result that the header row is hidden if I scroll down. I'd much rather have it outside the ScrollView but then I don't know how to align the entries with the header. Any ideas?
Try with something like this:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentTop="true">
<TextView
android:id="#+id/column1_header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="#string/column1_header"
style="?android:attr/listSeparatorTextViewStyle"
android:layout_weight="1.0"
/>
<TextView
android:id="#+id/column2_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignBaseline="#id/column1_header"
android:text="#string/column1_header"
android:textSize="14sp"
android:textStyle="bold"
android:textAllCaps="true"
android:textColor="#color/textColor"
/>
<TextView
android:id="#+id/column3_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignBaseline="#id/column1_header"
android:text="#string/column3_header"
android:textSize="14sp"
android:textAllCaps="true"
android:textStyle="bold"
android:paddingRight="8dip"
/>
</LinearLayout>
<ScrollView
android:layout_below="#id/header"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/scroll_view_container"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<rows>
</LinearLayout>
</ScrollView>
<RelativeLayout>
you don't want to do this with xml.
Because you simply can't reference views inside of an relativeLayout
from the outside and vice versa, to align things.
I had to deal with exactly your issue, as I implemented a in size selfadjusting tableView. The trick is to add all your textViews for one row into a ViewGroup (LinearLayout e.g, because easy to use with addView) and calculate the width of every row header in forehand. Than set the size of the viewGroups programmaticaly.
That's the key. This way, you can easily change your row header later and keep beeing flexible. Moreover you are not limited to a fixed size of columns.
calculate the width of the header
set the size of the (e.g) LinearLayouts for every row
add all TextViews to the LinearLayouts
This should hopefully help you. Answers to all the upcoming question for calculation sizes etc, should you find yourself on stackoverflow.
Greets, Steve.
OK, I found a solution: I'll have the three header TextViews outside of the ScrollView, as suggested by several commenters, and three additional "header" TextViews with the same parameters plus android:visibility="invisible" inside the ScrollViews. Those invisible TextViews will be used to align the visible entries.
Thanks for your answers!
In my app I have the following layout, and no matter what value I give the textview doesn't change its width. Can someone please help me in correcting this layout.
Here is the XML code:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_marginTop="15dp"
android:descendantFocusability="blocksDescendants" >
<TableRow
android:layout_width="match_parent"
android:gravity="center_horizontal" >
<TextView
android:id="#+id/rec_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/fill_rece"
android:ems="10"
android:focusable="false"
android:padding="10dp"
android:textColor="#FFFFFF" />
<ImageButton
android:id="#+id/btn_rec_delete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/content"
android:src="#drawable/ipad_postcare_landscape_from" />
</TableRow>
</TableLayout>
I also get a warning near TableRow saying "This TableRow layout or its TableLayout parent is useless". Please guide me.
Thanks in advance.
Try this one Insted of table use Linear Layout with and set LAYOUT_WEIGHT property. This property shares the equal amount of space for text view and image button
<?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="wrap_content"
android:orientation="horizontal"
>
<TextView
android:id="#+id/rec_name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/fill_rece"
android:focusable="false"
android:padding="10dp"
android:textColor="#FFFFFF" />
<ImageButton
android:id="#+id/btn_rec_delete"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:contentDescription="#string/content"
android:src="#drawable/ipad_postcare_landscape_from" />
</LinearLayout>
try this....,you can add android:textSize="some value" which you want t o give
<TextView
android:id="#+id/rec_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:padding="10dp"
android:text="hllo"
android:textSize="25dp" />
You might need to use
android:layout_weight
I am mentioning one example for your help, also make sure your every element has height and weight with it, to display everything correctly
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#drawable/layout_border"
android:weightSum="1.0"
android:id="#+id/r1c1r2">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:textIsSelectable="true"
android:id="#+id/key"/>
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:textIsSelectable="true"
android:id="#+id/key2" />
</LinearLayout>
Give the textsize using:
android:textSize="some value"
try to give size according to your requirement you have the width of the table row and textview set as match_parent hence it(textview) can't change it's size.
android:layout_width="50dp"
The following is the XML of my layout. It explicitly states that the title, time and description TextViews should be under the image of the alarm. However, as the screen shot shows, the TextViews have moved into the ImageView. Why does this happen and how can I fix this? The problem only started happening when I added the scrollview.

Cute app :)
hmm... not sure why it's doing it, looks like you have the right code, without busting out eclipse. but i've also had some weird bugs with relativelayout that i didn't understand and didn't have time to debug.
i do know of an alternative way you can accomplish what you're looking for -
have a scrollview that encases a linearlayout instead of a relative layout. Do these things:
For the linearlayout, you can set orientation = vertical so that it's still a top down order.
For the part where you need two textviews where one is aligned to the right and the other is aligned to the right, you need another inner linearlayout with its orientation=horizontal. then have one element align parent left, and the other align parent right. add a weightSum=1 attribute to this linearlayout and have each of the two textviews layout_width=0.5 so that each is half the width of the screen
Apply a weightSum=1 attribute to your outer most linearlayout, and see each element inside so that it's layout_weight sum adds up to 1. layout_weight will allow an element to take up that much % of real estate on the screen. like if you set your imageView to have android:layout_weight=0.8 then it'll take up 80% of the screen... since mathematically, (layout_weight/weightSum) = (.08/1) = 80%
try to use that mechanism instead, and if should work :) if it's confusing i can give code
example
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1">
<ImageView
android:id="#+id/img_alarm"
android:layout_width="match_parent"
android:layout_height="0dip"
android:src="#drawable/alarm"
android:layout_weight="0.7"
android:contentDescription="#string/content_description_layout_alarm"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.1">
<TextView
android:id="#+id/lbl_alarm_title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:textSize="20dip"
android:textStyle="bold"
android:text="#string/empty"

i hope this deserves at least an upvote for the effort :D
been trying to figure out Android layouts and having a bit of an issue. i got as far as figuring out how to get the objects in the places i want, using a RelativeLayout (tried LinearLayout and TableLayout combinations, only to find that gravity and attributes weren't doing things i thought they would...) but i've run into an issue with text bleeding behind other text.
the second item demonstrates the problem. i'd like to have this same layout without the text bleeding. here is my code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_width="wrap_content"
android:padding="6dip">
<TextView android:id="#+id/item_text_product"
android:layout_alignParentLeft="true"
android:textSize="24sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/item_text_total"
android:layout_alignParentRight="true"
android:textSize="18sp"
android:textStyle="bold"
android:textColor="#00aa00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/item_text_count"
android:layout_alignParentRight="true"
android:layout_below="#id/item_text_total"
android:textSize="12sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/text_count"
android:text="Count: "
android:textSize="12sp"
android:layout_toLeftOf="#id/item_text_count"
android:layout_alignBaseline="#id/item_text_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>
Put first your item_text_count and text_count items (I mean, put them above the text_count in the XML)... then:
<TextView android:id="#+id/item_text_total"
android:layout_alignParentRight="true"
android:layout_toLeftOf="#id/text_count"
android:textSize="18sp"
android:textStyle="bold"
android:textColor="#00aa00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
As you see, the difference is android:layout_toLeftOf="#id/text_count".
Set a maxEms attribute on the product TextView so that it's width can never exceed n ems.
That way should be the best solution.
I think you just have to add android:layout_toRightOf="#id/item_text_product" to the second textView, but can't try it right now.
The issue is with wrap_content, with it the view is going to expand to fit its content.
What about shrinking the text and using nested Linear Layouts?
You might try and use a LinearLayout if you don't want overlapping behavior.
Something like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_width="wrap_content"
android:padding="6dip">
<TextView android:id="#+id/item_text_product"
android:textSize="24sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView android:id="#+id/item_text_total"
android:layout_alignParentRight="true"
android:textSize="18sp"
android:textStyle="bold"
android:textColor="#00aa00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/item_text_count"
android:layout_alignParentRight="true"
android:layout_below="#id/item_text_total"
android:textSize="12sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/text_count"
android:text="Count: "
android:textSize="12sp"
android:layout_toLeftOf="#id/item_text_count"
android:layout_alignBaseline="#id/item_text_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>
</LinearLayout>
layout_weight="1" causes that view to expand to fill the available space not taken up by the right-hand views.
I am trying to make a relativeLayout with three textViews in a column on the left and two buttons next to each other on the right. The problem is, when the first textView is short "i.e. 3 or 4 characters" the textViews below get wrapped whenever they are longer then the first textView. I don't want this and want them to go all the way to the buttons if possible. I know I'm probably missing a parameter or something similar. Can anybody help me?
<LinearLayout android:id="#+id/LinearLayout02" android:orientation="vertical" android:layout_height="fill_parent" android:layout_width="fill_parent">

Why not just use a table layout? It might be a little easier to design because you are talking about columns and rows. The problem with relative is that its going to change based on the others, if you don't want this to happen then using a table layout with x rows and y columns will be a lot easier.
Along with this, using table layout allows you to specific zeroing-in in a particular column or having a particular element consume more than one column.
I have experienced something similar when creating a home screen widget. As widgets have limited options, a TableLayout could not be used. I reverted to something that translates as follows to your situation:
<?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="horizontal" >
<LinearLayout
android:id="#+id/RelativeLayout_class1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right"
android:orientation="vertical"
android:visibility="visible" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="short" >
</TextView>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="shrt" >
</TextView>
<TextView
android:id="#+id/TextView_class1_room"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="quite a bit longer" >
</TextView>
</LinearLayout>
<LinearLayout

android:layout_height="wrap_content"
android:text="button 2" >

</LinearLayout>
</LinearLayout>
