I have a textView where I am getting data from JSON and displaying. My problme is that I want to store all data into database but want to display few letters on TextView. I used
android:singleLine = "true"
Is there any way to show only few characters in textView but getting full data in background ?
You can use in xml android:maxLength="10"
You can use android:maxLength="10" (for showing only 10 characters). Apart from android:singleLine = "true" if you want to show 3 dots at the end of the text then you can use android:ellipsize="end"
To store the full text data in database , store the json string which comes from server , however in the textview use maxLength property to restrict the number of characters. Hope this helps.
android:maxLength="<Any character Length>" (for showing only n
characters).
android:singleLine = "true"
if you want to show 3 dots at the end of the text then you can use android:ellipsize="end"
So storing the full text data in database , store the json string
which comes from server , however in the textview use maxLength
property to restrict the number of characters.
Hope this will help you !.
android:singleLine = "true" doesn't have to do anything with the data in background. You will get your data in database as it is.
singleLine will only show the maximum data it can show in a single line on UI.
However, you can use maxLength to get exact maximum characters you want to show, maxLines to set maximum number of lines the TextView can be expanded to and ellipsize to show that there are more words but it can not be fit in a single line.

I have a TextView and I set text which I receive from Backend.
the text is either from 1 to 3 words.
Maximum the textview can be 2 lines.
I am using setAutoSizeTextTypeUniformWithConfiguration
and text.breakStrategy = LineBreaker.BREAK_STRATEGY_SIMPLE
And I don't have any success.
wondering is it possible if the text is single word I don't want to split it. I would like to have it in single line with small textSize. if the text is 2 words and long I am fine to show it in 2 lines. The problem is it always breaks the word in 2 lines if it is long while I don't want.
The only solution that comes to my mind is before setting the text to a textview, check whether text has spaces in it.
If it has not that that means it's a single word, so set ptogrammatically maxlines to 1, otherwise set maxlines to 2.
EDIT: I missed text size part. I use this library for autoresizing and it worked so far https://github.com/jivimberg/AutoResizeTextView
it's automatically handled in androidx.appcompat.widget.AppCompatEditText and just set android:maxLines="2"
remove all other properties you set
I want to access text of particular line in a multi-line TextView. Any suggestions on how I could do this?
Fetch the Layout (android.text.Layout) of the TextView by calling mTextView.getLayout(); There you can for instance use the getLineStart or getLineEnd methods to get the offset of the text. That combined with getText and used using normal String operations should probably be enough for u!
By default, text view is multi line. Set the text with new line characters for ex. "First line \nSecond line".
Another option is listed here : https://stackoverflow.com/questions/2610280/how-to-get-multi-line-text-on-a-button-in-android
I have a TextView and my need is to add 10 characters in that TextView by code. But when characters are greater than 10, they should be display in TextView but with 8 character + .. of that charsequence. And when I want to read text of that TextView I must get full charsequence not 8 character + .. . For example
tv.settext("ASDFGHJKLQ") // this is 10 characters long, so no rule required
but
tv.settext("ASDFGHJKLOP") // this is more than 10 characters then it should be display as
ASDFGHJK.. in textView, but when I retrieve the value of textview, it should return ASDFGHJKLOP instead of ASDFGHJK.. , so how can it be done.
That textView is row of a listview.
Try adding this to your TextView (marquee or end):
android:ellipsize="marquee"
You may also need:
android:scrollHorizontally="true"
Without scrollHorizontally="true" you may still get the text wrapped rather than appended with ... I use these very 2 lines to display a list view in my app. The 3 long lines I have get appended correctly.
This truncating happens because it does not fit in your list item. Reduce the font ?
or ellipsize ?
I see only one solution. But maybe there are another solutions.
To store you string.
If string's length is greater than 10 letters set text of your TextView with 12345678..
And if you want to get right text you should take the value of the string and not of the textview.
in my custom listview that Contain an image and EditText ,and in EditText i can comment the photo ,i can give text comment max length of 50 ,when i lost the focus in EditText i want to rearrange the text in EditText in following format
EG: suppose comment contain 40 char and user can at a time directly view only 20 char,then if i lost the focus text should be rearranged that at the end there should be 3 dot
Original Comment i wirte:eg-> eeeeeeeeeeeeeeeeeeeeeeeeeee after i lost focus it should shown as-> eeeeeeeee...
it's importent that the nothing happens to original text because these text i want to send to server, and i directly take these values,and if am replace the text by new this type of text this will create problem, also when i gain focus i need to see full text also.
i have used this android:ellipsize="end"
You have to set a specific value for android:ems on your EditText if you want to use the ellipsize function as it will only truncate strings longer than the EditTexts width. With ems or maxEms you can specify how many ems wide your EditText should be. Also don't forget to set android:singleLine to true.

NB: i set android:singleline=true
Try android:ellipsize="end", or if you want to fade, try android:fadingEdge="horizontal"
Use the android:ellipsize="end" in you XML layout file. You can also show the scrolling text by using android:ellipsize="marquee".
