I am using shopping experience to design a section, there doesn't seem to be a way to center icons horizontally. For such small thing do I need to create a plugin? or is there a some-way to center them? There is option to vertically center but not horizontally. I have used "Three columns, boxed". I played around with layout CSS classes but that didn't help.
Have you tried display mode "Cover"?
Okay, so I'm really trying to do a lab for a class thing and I don't get why I can't have a textbox that takes up the width of the phone and a button that takes up the width of the phone on the bottom, but I don't know why that is? Here's a picture of what I have.
I know this is a noob question but it hasn't been addressed yet on the online course I'm taking and I really need an answer because I wanted android development to be as easy as .NET on windows.
Well anyway here is one picture:
Also here is the other picture:
Notice if I try to make one element bigger, it leads to it pushing the other one out of the activity, I want to have one activity with both elements taking up the entire width of the phone.
Does anyone know what I'm doing wrong?
EDIT: I'm using Ubuntu 14.04 not Mac OS X.
Your controls are children of a LinearLayout with android:orientation="horizontal". This means that the parent ViewGroup is aligning them horizontally; you cannot get the children aligned vertically in this configuration.
If you change the attribute to android:orientation="vertical", you will achieve the result you're looking for.
I strongly suggest getting yourself familiar with the default set of layouts available in the Android SDK by reading this official guide.
Edit : Please refer to this answer for placing views at bottom of the screen.
When you use a android:orientation=horizontal orientation in the layout, the views are stacked/placed in a single row. Since both your views have their width set to fill the screen, only the first one is shown/seen.
What you want is the vertical orientation. This places the views in a single column, one below the other. The width set to fill-parent will allow you the view to occupy all available space.

There are 8 buttons from top to bottom on my layout.
When i run .apk in my device, it is shown good. But when i run same .apk on an old android device, last 2 buttons is not shown. they dont squeeze on display
Please, help me.
Give equal weights to all buttons and set height and width of all buttons as wrap_content.
Ad scrollview to your buttons.It is because the screen is small.
Basically, I have an usercontrol as main container, inside which I have a few groupboxes and buttons. But, my interface controls will not be resized and positioned properly as what I expect in design interface.
I've already tried to change the anchor and dock properties but none of them serve my purpose.
I searched online and found something called viewbox in WPF, I'm wondering if there is something like "viewbox" in visual studio 2010?
Please help!
Try using TableLayoutPanel container and put your controls in it. It is similar to the idea of table in HTML where it is divided to rows and columns each one of them can be set to either a set of pixels or a percentage. Usually if you want to use re-sizable form, usually you should have a control that will give you good results when stretching such as image, multiline textbox etc... In addition, put the dock property to fill to get the stretching you want.
I hope this info was useful for you.
Application develop in the J2ME using LWUIT. When I port this application on the Samsung Device it create the following problem.
int h = Display.getInstance().getDisplayWidth();
It returns 388 for the Samsung GT S5250. So when I draw an image using this dimension it displays a white strip at the bottom of the screen. When I call the Form.show() it displays correctly and height is 400 so how to resolve this issue.
I want to know how the Form size is calculated in LWUIT and how it takes MenuBar Height and white strip display at bottom of the screen.
I think you typed getDisplayWidth() where you meant to type getDisplayHeight().
Regardless, the problem you are seeing is due to a bug in the samsung device. LWUIT invokes the full screen mode in MIDP which hides the native title area, however that doesn't always happen immediately in some devices and thus LWUIT gets incorrect information from the devices. A refresh usually solves this and by the time LWUIT draws on the screen the size is corrected.
Generally the solution is rather simple, create generic code to create your image and if the image dimensions are inappropriate when you are about to draw to the screen then just recreate the image on the fly. This will also solve the issue of device rotation which might pose a problem too.
