[android-developers] Re: layout problem

[Piren]

change the linearlayout to warp_content and put it in a 
RelativeLayout/Framelayout and use the proper centering field 
(centerInParent/layout_gravity)

[android-developers] Re: layout problem

[viktor]

http://developer.android.com/reference/android/widget/ImageView.html#attr_android:scaleType

set scale type to the fitXY

Or you can calculate width and height for your ImageView manualy by
ParentView (width, height) with correct aspect ration for your image.

[Abhishek Akhani]

I have also encountered this problem i think 9 patch images take some 
space on all four sides which makes the inner content to squeeze you 
have to readjust your text view or just use png... :-)   this is what i 
did

[android-developers] Re: layout problem

[dashman]

thanks - that was the problem.

but this seems like a layout bug.

if i have a LinearLayout with 3 elements in them
with the 1st and 3rd with layout_width of wrap_content and then
middle one with fill_parent. it seems relatively clear what i
want done. the middle element will take all the space after
the 1st and 3rd widths have been allocated.

even if i do a wrap_content, it doesn't work - tablelayout takes
the full rest of the row.

the only way it works - is with a hard pixel amount.

[android-developers] Re: layout problem

[dashman]

on further researh, it was the stretchColumns inside the
tablelayout - causing the problem

TableLayout
android:layout_width=fill_parent
android:layout_height=wrap_content
android:stretchColumns=1

but again, that attribute should be subservient to the layout_width.

if i set the width to wrap_content - it still strectches even though
the content width is quite a bit less than the remaining width.

[grace]

hi,
your table layout as defined in your xml specifes to fill the parent
with its content.
that is why it is not showing up the second image button.
try to adjust the width of the table layout so that image button can
also be seen
TableLayout
 android:layout_width=fill_parent /here
 android:layout_height=wrap_content
 android:stretchColumns=1

 works fine!

 i wanted to add an image-button to the

 problem is that image-button never appears
 on the screen.

 if i comment out the tablelayout (i.e.
 just 2 image-views in the layout) - then
 the image-button shows up.

 i've verified the code for the image-button -
 it's correct.

 it's almost as if one cannot have a view

 I'll add an example of this sort of layout to my to-do list to add to
 the book. As I mentioned to somebody else earlier today, it's a long
 to-do list...

Sounds good.

One more thing wanted to ask, regarding Layouts and Themes.
I have my Application (in the AndroidManifest.xml) set to the theme
below. It draws a background picture on all my activities. However, on
a select few (about 2) I am not wanting the background to be drawn but
instead I want to implement my own view using the canvas. So what I am
wanting to know is, can I override / switch off themes in certain
activities ?

Themes.xml snippet
style name=Theme.SVP parent=android:Theme
item name=android:windowBackground@drawable/background/
item
item name=android:windowNoTitletrue/item
/style

Every activity can have its own theme. Just use android:theme on the
activity / tag in your AndroidManifest.

Hi Romain,

Thanks for that, but I am actually wanting to switch the theme off so
it's just normal. Would it be enough to just tell it to render the
default android theme but I do not know how to do that.

Found it, I just set my theme in the activity to @android:style/

 Move your ListView after the TableLayout the RelativeLayout definition

 because you're going to need to give your TableLayout an android:id

Superb as always Mark, thanks. Works perfectly.
Funny thing is I know about the layout_above tag from reading your

  I want to center a TextView inside of a layout.  I've been playing

  Please help!

  ?xml version=1.0 encoding=utf-8?
  LinearLayout xmlns:android=http://schemas.android.com/apk/res/

        android:orientation=horizontal
        android:gravity=center
        android:layout_width=fill_parent

            android:layout_width=fill_parent
            android:layout_height=fill_parent

  /LinearLayout

 Step #1: Use RelativeLayout.

 Step #2: Give the TextView the android:layout_centerInParent=true
 attribute.

 Step #3: Have a beer. Possibly preceded by root or birch, if that's
 your preference. ;-)

I want to center a TextView inside of a layout.  I've been playing
with the XML code below and can't get it to work?
Please help!


?xml version=1.0 encoding=utf-8?
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
  android:orientation=horizontal
  android:gravity=center
  android:layout_width=fill_parent
  android:layout_height=fill_parent 

  TextView
  android:id=@+id/txtMessage
  android:layout_width=fill_parent
  android:layout_height=fill_parent
  android:gravity=center /

/LinearLayout

 I tried to post a much simpler version of the question in the beginner
 group but its been hours and it still has not showed up.  I think they
 have a problem with new topics over there.

Step #1: Use RelativeLayout.

Step #2: Give the TextView the android:layout_centerInParent=true
attribute.

Step #3: Have a beer. Possibly preceded by root or birch, if that's
your preference. ;-)

Hmm it looks like my diagrams didn't post quite right to the message
board.

Just use your imagination to picture nicely drawn boxes that borders
the text :)

 First let me say that this problem is probably real easy to solve.
 But I've been looking at it all night and its got me stumped.  So to
 keep from pulling my hair out, I'll post this problem here where some
 expert can look at it for 5 seconds and figure out what I'm an
 idiot :)

 Here's the background info for what I am trying to do.  I have a
 ListView that displays text input from the user (similar to the
 Android notepad example).  I want to center the text inside a
 background image (text bubble).  I want the text bubble to be centered
 in view.

 This is what an ideal to look like.

 Here is the code I'm using.

 LinearLayout xmlns:android=http://schemas.android.com/apk/res/
 android
     android:layout_width=fill_parent
     android:layout_height=?android:attr/listPreferredItemHeight
     android:padding=6dip
     android:gravity=center 

     LinearLayout
         android:orientation=vertical
         android:layout_width=fill_parent
         android:layout_weight=1
         android:layout_height=fill_parent
         android:gravity=center
         android:background=@drawable/textbub 

         TextView
             android:id=@+id/txtMessage
             android:layout_width=fill_parent
             android:layout_height=0dip
             android:layout_weight=1
             android:paddingLeft=40dip
             android:paddingRight=20dip
             android:gravity=center /

     /LinearLayout

 /LinearLayout

 Here is what is actually displayed by my program.

 Above is what the first entry looks like.  Not what I want.
 Below is what the rest of the entries look like after the first.
 Definitely not what I want.

 So what am I doing wrong?

 Bonus Question:

 A RelativeLayout is supposed to be more efficient than a LinearLayout.
 Can I use a RelativeLayout for what I'm trying to do instead of a
 LinearLayout?
 If so, how?
