Recently, I've been working for some theming project for Android launchers. I need some guidance and advice from the people around here that could help me with this.
I have created one sample icon for Opera mobile with the size of 192x192. The question is, if I made that icon size as mentioned, should I create another size for it, e.g. 128x128? I'm a bit confused.
Thanks.
I am not sure if understand your question. If you add a drawable resource to Android Studio, it automatically resizes it to multiple sizes. If you have created one, that will be resized automatically.
Hope this helps.
If you want to design icons for android, you better design some for different resolutions. You have to make an icon for each. See at this article https://developer.android.com/guide/practices/screens_support.html#overview. There are the different densities and the multiplication factors.

Hi all !!
I'm newbie to android, Can i get any solutions to make my android app layout that fits in all screens.
If there is any tutorial on it, that would be appreciated !!
Thanks,
Create the following folders in res and add the xml in that
res/layout-small
res/layout-normal
res/layout-large
res/layout-xlarge
And open it from studio layout and make changes.
this link helps you.
The Android resource system gives you the tools to provide alternate resources based on the available width, height, or smallest width — important measurements that serve as the basis for choosing when to change our UI based on the space available.
Width and Breakpoints
Width is perhaps the most important dimension when it comes to choosing when to change your UI. This is because width is the basis for the breakpoint system.
A very good example is here
I am working on windows 10 mobile app. If I design an UI for 5' device, it doesn't look good on 5.2' device. Also on emulators of different screen size show messed up UI. Is there any work around this? Or do I have to design it for every screen size?
Usually, please avoid to have fixed Width/Height for your controls. With a Grid layout, you can set columns/rows and place your controls inside each cells. This is a first level to adapt properly your interface. In addition, UWP provides AdaptiveTriggers if you want to adapt the layout based on the screen resolution (cf. https://channel9.msdn.com/Series/A-Developers-Guide-to-Windows-10/07) for additional information. Last but not least, please check Design&UI documention on https://developer.microsoft.com/en-us/windows/design.
The trick is with UWP that you can design for every screensize at once. It's just a responsive design you use (either HTML/CSS or XAML). But you have to use the right controls and settings.
Some guidance on how to design for various sizes can be found at the MSDN design page.
To create a dynamic layout with XAML, see this article. There are various panel-types you can use to do the layout (see this article). But if you really want to build a responsive UI (or change it dramatically in various sizes) RelativePanel is your friend.
I am new to Android Studio. I am trying to make a basic application that adds two numbers, but each time I move something around, The entire layout gets messed up.
I added a separate View in the center to act as a reference point to counter this, but it is still getting very annoying.
Any idea on how to fix this? I am using Studio version 2.1
If not, is any other way to design the user interface without having to deal with relative layouts?
I have tried linear layouts but those only allow me to place my elements in fixed places which I cannot use in my app.
Please guide me.
Note: I apologize if this question is too simple. I am a newbie after all, do forgive me.
Thanks in advance!
This is indeed the function of RelativeLayout in Android Studio. If you are getting problems with dragging and dropping with RelativeLayout then you should try any other layout. eg. ConstraintLayout
2nd Solution:
Try adding new buttons instead of copying and pasting old ones.
Have you tried using margin: http://android4beginners.com/2013/07/lesson-2-2-how-to-use-margins-and-paddings-in-android-layout/
also look you can align certain object in the xml code relative to eachother, have no link for that atm
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.

I'm new to Android development.
I'm using drag and drop to pull down a default spinner onto my layout.
However, the default is not the one I see everyone using with the triangle on the bottom right.
An example of what I see is:

Whereas what I'm looking to achieve is this:

Is it a styling issue?
Apologies for ripping off other people's images, I don't have enough rep for uploading my own images.
Thanks so much!
I've Solved my issue by setting the Theme of the application/activity to Holo.Light. Hope this helps other people in the process.
