I've been developing an application similar to the Google Keep, and was wondering how actually they allocate the text size to a note (algo)?
Do they just allocate size depending upon the Note length?
Or they also check for Card Dimensions i-e card width etc?
Its a bit confusing, because sometimes notes have equal card size dimensions with font-difference, and sometimes notes have both different size dimensions and text size?
So basically, the Question is, What is the algorithm/method to calculate the text size for a note?
you have to use auto-fit TextView for this & add it in RecycleView or ListView(whatever you want) item layout. here is one of stack answer of AutoFit-TextView and source code from github android-autofittextview
apply max text size in TextView then it automatically adjust if there is more text
Do they just allocate size depending upon the Note length
No,
Or they also check for Card Dimensions i-e card width etc
No
just make you TexView size wrapcontent its allow you to add all text in textview like whatsup chat thread.
Edited
you have to manage like below way
*in Google keep text size depend of words. text length is 10 then maximum text size. text length is 30 then medium textsize and more then 50 then small text*
they are using two typeface one is for title and another is for text message

So I have read possibly everything about the difference between sp and dp. I can say that I do understand why sp is better than dp regarding text size. One thing I don't understand and want some help with is how do I make the text look the same with every possible font size the user has selected for their phone? Is it that bad to use dp for text size? (I know that the app won't take the user's phone font size into consideration but at least it will look the same across the board.) Any advice would be appreciated.
To make the text look the same irrespective of the users' choice, use dp. To change the text size according to users' choice use sp. So, if you have a constraint that the text size should remain the same use dp.
Is not bad at all to use DP as text size. It just won't follow the users preferences regarding text size. We have to use the tools we have, to best fit our needs. I always use DP in elements wich i need to maintain the layout. If you don't want the text size to change, use DP. Some times i use textAutosizing When the text changes. And often i use sp, when dealing with "content" text, wich can grow and scroll, shrink and fit.
I have a function that generates a random number. Then, I place the number in a TextView. When the number is a single digit, it fills the TextView perfectly, but when the number is two digits or more, it only shows a single digit because the text size is huge.
How do I automatically fit the text size to the TextView? Something like reduce the text size so that all the number will be shown in the TextView.
I don't have enough reputation to comment so I must abuse an answer. No need to reduce the number's size. Just make sure the TextView is set to wrap_context in the layout:width property and also possibly the layout:height property, that should fix your formatting problem.
I am writing an app about eye test. It is necessary to set the standard text size. I used the following code but it showed what I did not expect.
Typeface type=Typeface.createFromAsset(getAssets(),"Optotypes.ttf");
textView2.setTypeface(type);
textView2.setTextSize(TypedValue.COMPLEX_UNIT_MM,25);
textView2.setText(randomLetter);
I expected the textview show a 2.5cm letter but it is not the exact length/height still.
This situation appear also on different device.
The next problem is that the size is different between the original font and ttf I added. (the original font didn't show the text with 2.5cm also.
Is my code wrong or anything else i missed ? Thanks guys . it is important to me.
I think you're missing how Android handles text sizes.
In Android, you should specify text size in SP units, so Android can scale it accordingly to the user's font size preferences. Never specify hardcoded pixels or centimeters.
Check this references for documentation on the subject:
http://developer.android.com/guide/topics/resources/more-resources.html#Dimension
http://developer.android.com/reference/android/widget/TextView.html#attr_android:textSize
What is the difference between "px", "dp", "dip" and "sp" on Android?
If you want to set the text size in SP programatically, you can do this
// same as android:textSize="15sp" in XML
textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 15);
-- EDIT
Keep in mind that by just setting a certain text size it doesn't mean that every letter will be of that size. Remember that there are multiple letters with multiple sizes. For instance, with a size of 20mm, this is what you get
Because Android needs to accommodate every possible character in a textview with the size you provided. That being said, textSize is not 100% accurate to what you provide to it.
If this is not enough for you, please provide more details of the problem you have at hands.
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.

I am making CSS voice bubbles, and I fit the text to the bubbles using em to set the text size, but now when I zoom in the text changes size too and it overflows out of the bubble. I don't want to set the text size with px because I want it to be cross-browser accessible, so is there a way to make it so the text doesn't scale itself to always fit the screen?
i think you should use % instead of em.
