Good morning!
I'm currently trying to create a view similar to this mockup.
I have put down 3 different screen sizes so you can see the issue.
I have a header background image (grey box) with an angled bottom. On the right I want to display an image, which obviously needs to be positioned.
Positioning it horizontally is no issue but how can I position the image vertically? I have it positioned fixed for one screen size but obviously need to make it flexible.
Any ideas? Help would be much appreciated!

You can definitely use measure as #rajesh pointed out, or you can use Dimensions. As far as getting the layout consistent across devices, using position absolute and measuring the device height should allow you to get consistency across these devices.
Check out this example I set up, it should be a good starting point at least.

My problem is three-fold. I'm going to try to explain as detailed as I can, because I've asked this question before and haven't gotten any clear answers.
What I'm Trying to Do:
I have diagonally shaped images, that I'm trying to make clickable, so I separated them out of the background image. They were originally one image, but I've cut out several pieces of the image and I want to align them identically to how they were in the original image. This might not the best method for what I am trying to achieve, and if there is a better way to make non-square areas of an image clickable, that would solve all of these problems. If not, here is my problem. The problem is, as soon as I align them in XML, I boot them up on an Android emulator or my phone, and they are aligned differently on both, differently than the preview and from each other.
Below is my example, and I'll try to explain what I mean.
The black and white grid is my background. The brown, red, and yellow lines are separate images. I don't want to just combine them with the background, because I need those lines to be clickable. I'd set a button behind them, but they are diagonally shaped and I need the entire shape to be clickable. However, they have to be EXACTLY where they are in the background, aligned specifically as they are to the background. The problem is, as soon as I load it on another device, it scales, and everything misaligns.
It also misaligns depending the device, so I presume it's because it's scaling the different parts differently.
I need a way to align it the way I want it, and have each image scale together.
How I've Been Trying This So Far:
Initially, I tried just using XML. And herein was my first problem. My background image is 1920x1080. It loads on the emulator without a problem. However, if I try to load it on my phone, I get the following error:
OpenGLRenderer: Bitmap too large to be uploaded into a texture (5760x3240, max=4096x4096)
So that leads to my first question. Why is my 1920x1080 trying to load as 5760x3240?!
I bypassed this, by using Picasso to scale the image to 1920x1080. As a sidenote, in addition to programmatically loading the image, I also am removing the title bar. Here is my OnCreate:
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main_layout);
Picasso.with(this).load(R.drawable.backgroundimage).resize(1920,1080).into((ImageView)findViewById(R.id.background));
On the XML side, I've tried all sorts of different things. Relative layouts, linear layouts, frame layouts...None seem to scale the separate imageviews the same.
Which leads to my second question.
How do I scale two differently sized imageviews together, so that they maintain their alignment on different sized devices?
My second imageview is 198x547(this would be the equivalent of one of the squiggly lines in the example images) and even setting that in Picasso does not maintain my alignment. In fact, that doesn't seem to work at all, since I have to scale it differently to even match the alignment I have in the original image.
Summary Questions
I need a diagonally shaped portion of an image to be clickable. Is cutting the shape out as a separate image the appropriate method for doing so? If not, how do I make such a specific, non-square area of an image clickable?
I need specific alignments to scale together. Why aren't they?
Why does my png file upscale itself?
I'm creating a simple 2D racing game in Unity. The game has another subwindow that displays the enemy's view. Kinda like a small screen on top; that lets you know where your enemy is or what he's doing.
Currently, I'm using a secondary camera to follow the enemy and a render texture to limit the display of the subwindow as well as its size.
However, I want the size of the window to be flexible like if i want the ratio of the window to be 4:3 instead of a perfect square. With my current implementation, whenever I rescale the subwindow, it just rescales everything up including the view being displayed. What I want to happen is, when I rescale the subwindow, the area being displayed should just be wider. It should just cover more area because I made the window wider. I want the view to be independent.
Is there a way to do this with my current implementation? If not, how can I achieve what I want?
I'm new to Unity so I really hope someone could teach me. Thank you so much.
The are viewed is independant of the size of your window, if you want to change how much is displayed instead of just re fitting the same content in another size you'll have to work with the field of view http://docs.unity3d.com/ScriptReference/Camera-fieldOfView.html
I have this plot as part of a PySide program;
And there are two problems I have with it. The first is the ugly grey border. I know I can can get rid of it using the toolbar option, but I can't find a way to it programatically, or make it default to that when it plots...
The second issue, is that it is drawing the grid lines on top of the surface, which I would rather it didn't do... How do I get the grid lines to be drawn underneath the surface?
EDIT:
i'm using version 1.1.1;
this doesn't happen for all plot types - i.e.
that is fine.
If i try and plot multiple objects, then it can be a problem;
but i understand that's a limitation of mplot3d not being a try 3D engine, just a set of 3D images with a Z-Ordering, so the order of objects drawn becomes orientation dependant. (same graph - different angle: enter link description here).
The grid lines should surely always be at the bottom of the drawing though, no? Is there a way to force them to be?
Will.
I am designing a simple music app where the user gets to play instruments i.e. Drums, and the problem that I am facing is with resolutions.
The drums are images, which I have converted them into buttons. Everything looks great at the state that I have designed it.
However, when I switch to other resolution states, the button(image) are distorted, e.g. skewed, scaled, and looks nasty.
I have tried designing or arranging them via selecting 'Enable state Recording', but the specific designs for that state are not being saved.
Have you tried the approaches discussed here? http://msdn.microsoft.com/en-us/library/windows/apps/hh465362.aspx For the actual button sizes, make sure you are not fixing the width/height with pixel values. Use * weighted rows and columns to layout your grids and have the buttons autosize to fill a given cell in the grid. Then match with the appropriate image resource per the article.
Grids are great for dividing up available space but they can't account for changes in aspect ratios. If your items are still set to Stretch (or Fill) then they can end up out of aspect ratio. Another option is to design the entire layout at a fixed size (let's say 1024 x 768 or 1366 x 768) and wrap the entire thing in a ViewBox. ViewBox will scale all elements equally and maintain the aspect ratio, adding letterboxing (or empty space) on the sides / top & bottom if necessary. This might be a better approach for a drum kit.
Hope that helps.
Redid the whole project of designing again.
This time, I put the image inside a specific grid and that made things lot better. :)
I want to create an omnidirectional scrollview that works pretty much like the one in the "Wall of Sound" app. As in, the user should be able to pull into any direction and never get to an end. I want to keep the move to be smooth (and not see the pages change as you would in a standard scrollview). Does anyone know how that can be done? Or would I need OpenGL for that?
Create a 3x3 grid of views, each the size of the viewport. As the scrollview moves into another section, rearrange the views to constantly put the viewport in the center. In most cases 3x3 is sufficient, but if redrawing the views is expensive, you may want to use a larger grid (5x5 for instance). This requires that you have some mechanism for splitting up your full view into tiles.
You can implement the same thing using CALayer if you like. If you go that way, you should consider instead using CATiledLayer. See Matt Long's quick introduction on CIMGF.
