So basically I have 3 boxes on screen, each displaying different information regarding audio frequencys.
The top box shows the Note, Middle shows the pitch of that Note, and 3rd shows your pitch.
I wanted to have the numbers in a box, and since they constantly change, I wanted the box to remain a certain size instead of constantly increasing in size to fit the text. However, I also don't want to give the boxes a specific size as I want them to be able to resize depending on the screen size.
Is there a way to do this easily? Or would I have to create separate XML files for each device or something?
I will attach an image so you can see what I mean.

So just imagine that each box is resizing itself depending on what text is placed in the box.
Any help with this would be great thanks!
If "So just imagine that each box is re-sizing itself depending on what text is placed in the box" this is needed then in the XML for the TextView widget that you use for displaying the values use.,
android:layoutWidth="wrap_content", android:layoutHeight="wrap_content" . The wXh of the view would be adjusted according to the content (values) .
If "I wanted the box to remain a certain size instead of constantly increasing in size to fit the text." -If this is not done, that is if you have fixed width text widgets, then the text will be clipped if they exceed the max width.
2.1 By above if you mean same size on each device, then figure out the maximum possible width/height on a mdpi (320X480 mdpi) emulator for each textview, say 100px width and 80px height and is what suits you for the Note, then in the XML for the TextView widget for Note use android:layoutWidth="100dp", android:layoutHeight="80dp" where "dp" would give you device independent pixel size, meaning the size will be adjusted according to the screen density on which the emulator is running.

Hi I am developing an app for large screens (24 inch - 30 inch) and I need a way to make it easier for wheelchair users to use the app. The first idea I have is resize all activities to a percent (50%) and put layout to bottom left or right. But I dont know how it can be done and need help or a different solution for the problem.
What i want is with a button click resize activity layout to example below. orange color represents activity and black orange image is when activity size reduced to size.
You can set other xml which have difference size which make you can design your UI depend what type device user used. There four type size = small, normal, large, and extra large (CMIIW). You can use this for reference

I have read all about supporting different screens and I understand the concept of Density Pixels (DP). However one thing I am not sure about. Lets say I have an image file which is 200 by 200 pixels and I loaded it using xml with wrap_content attributes at the top left of the screen (0,0). Now let's say I want to place a textview programmatically beside it.
If I put the text view at coordinates (250,0). Does that mean that the text view will never overlap the image and will always be to the right no matter what the device density/screen size is.
I understand the distance ( gap) will be different but I am hoping my theory of not overlapping will hold.
I tried it on 2 device and no issues but I am not sure if this is coincendence
Thanks
If you are using px unit it will always remain the same. But if you are using dp unit instead of pixel you cannot definitely be sure.
By the way you should use toRightOf property instead of this approach if you only want this.
I want a text to have relatively same size in every Android device.
I have a canvas (fullscreen). In middle of this canvas is some text. This text fills 20% of my screen leaving 40% for both sides. I want these precentages to be true when text is viewed in any Android device.
I also want the same thing vertically.
Put the size into a Dimension resource using “sp” units.
I decided to measure width of text in pixels and save that value.
When text is loaded in different resolution, I multiply the original pixels with scale of resolution change. I loop up from text size one, always calculating new resolution and checking which matches the original resolution best.
I have a full screen png image with all descriptive text for each EditText. I want to place the six EditText input areas at the correct positions on the screen.
I understand the different layout folder names for different screen sizes, densities and orientations. So I would have different layout XML files for each.
My problem is how to place the EditTexts at the correct location, and have them scale what would be small amounts with the small variations of sizes as the full screen png image will scale.
I believe that I should not specify locations, even with density independent pixel (dp |dip), as they may not work in future versions.
I cannot find anything on searching for this problem. What I can think of is a Relative Layout with blank or transparent dummy TextViews pushing the EditTexts to the correct positions.
My reasons for doing it this way with one png image for all the non-EditText parts of the screen are (I think)
- Can get a nicer screen image
- Is more efficient to place one png ImageView on the screen
- Is how it was done in another mobile environment
Any thoughts or suggestions?
My recommendation is that you remove any text parts and other that needs to be aligned from the background image, then create a RelativeLayout where you can add these as real TextViews/EditTexts.
This will give you the best result and flexibility considering all the different screen sizes and resolutions available for Android phones and tablets.
Is it possible to set TextView's text size to be the same as TextView height, when TextView height isn't predefined(WRAP_CONTENT or FILL_PARENT)?

i also wanted to do something like this and the closest you can seem to get is to say android:textSize=20dp (or whatever size you think is appropriate) for either your style or each element that is displaying text. since dp is device independent pixels, if it appears to be taking up the whole screen on your device, then it is supposed to appear that way on all other devices too. you might want to check on this as you might have to choose a different dp value for each of the different size/density combinations possible (depending on what kind of devices you are aimed at, also whether you are allowing the use to change the orientation) this has all that info.
