This is what the app looks like.
I just started
studying Android.
but I want this.
I just started st
udying Android.
I searched for an answer.
This is the search result.
It's a bit hacky, but you could replace spaces with the unicode no-break space character (U+00A0). This will cause your text to be treated as a single string and wrap on characters instead of words.
myString.replace(" ", "\u00A0");
Where should I put that code????
If you don’t want replace string in code, and purpose is only chaning void to nbsp,
You can use #BindingAdapter feature of AAC.
#BindingAdapter(“app:text”)
fun TextView.setText(str : String){
this.text = str.replace(“ “,”\u00A0”)
}
in XML,
<TextView
...
app:text=“Put your text here”
/>
Quick way would be replace all spaces with \u00A0 in your xml file
<TextView
...
app:text=“Put your text here”
/>
&# 160;(without the space) is \u00A0 in html unicode excape syntax (https://unicode-table.com/en/00A0/)
Or when setting via code
String myString="put your text here";
textView.setText(myString.replace(" ", "\u00A0"));
I have an issue when mixing in one string English, Hebrew and digits.
The order of digits next to Hebrew is getting reversed, no matter what order I make - fist digit and then text, of first text and then Hebrew - it's getting reversed to: on the left digit, on the right text.
My text example is:
String leftPart = "10 gr";
int numder = 8;
String hebrewText = "כפות";
String rightPart = hebrewText + " " + number;
String finalString = leftPart + " · " + rightPart; //10 gr · כפות 8
I want to display the digit 8 in the end of this string, after the Hebrew word, not before it, but I'm unable to do it even here...it's getting reversed because of the English text in the begging.
Even if I change the order to:
String rightPart = number + " " + hebrewText ;
the result is the same...
Any ideas? It's looks like something simple that I'm missing
A tip for forcing English to be shown nicely when mixed with Hebrew:
Wrap the English (or numbers) words with LRI and PDI (check here: https://unicode.org/reports/tr9/ ) .
For example, instead of these (first word is in English) :
<string name="test">ABC היא האפליקציה הכי טובה</string>
<string name="test2">%1$s היא האפליקציה הכי טובה</string>
Use these:
<string name="test">\u2066ABC\u2069 היא האפליקציה הכי טובה</string>
<string name="test2">\u2066%1$s\u2069 היא האפליקציה הכי טובה</string>

Nothing is screwing up here, this is actually correct behavior. The number is coming after the end of the hebrew word- the end of the hebrew word is on the left. What you seem to want is for the number to come before the hebrew word. But when you combine it with english like that it doesn't know tht the number is supposed to be bound to the hebrew part and not the english part, so putting it before the hebrew doesn't work either.
I'd suggest putting the number before the hebrew part and wrapping the number and hebrew text in unicode right to left mark characters, to tell it explicitly the 8 is part of the right to left text.
Alternatively you could put the number after the hebrew text but use an rtl mark before the hebrew and a ltr mark after. Which is probably a slightly better way of doing things overall if you want more complex embedding elsewhere.
<string name="message">هذا المجلد يحتويى على %1$s ملفات. الرجاء التأكد قبل الحذف. الملفات المحذوفة غير قابلة للإسترجاع.</string>
I wanna put "%1$s" in an arabic string, but as you can see here, word, notepad++, utraedit, all failed to get the right string. how you guys edit arabic string?
In android Studio 2, RTL support is not turned on by default,
Configure it Manually:
1. In your Computer, go to the [android-studio2.0]/bins/idea.properties
2. add editor.new.rendering=true to the end of idea.properties
3. restart your android studio.
This is a source of frustration when editing mixed-direction text. What counts is the logical order of the text, not how any of the editors display it. When you finally format the string at run time in the app, the %1$s will be replaced by whatever string you pass to the formatting method. The only thing that matters is how the string will be rendered after the substitution.
The easiest thing to do is to write the message without the %1$s, then position the insertion caret, paste in the format code, and simply ignore how the editors screw up the bidi analysis. (The screw-up is because the editors are using a left-to-right base level. In some editors, you can set the base flow to right-to-left, but then the xml markup ends up being unreadable.)
When I work with RTL text and I need to put a place holder(%1$s) or LTR words, I just write it in MS Word and copy to the IDE.
It works for me in Eclipse and Android Studio.
All you need to check is that the components that displays that string like TextView has the right gravity.
You can try in Activity..
String formatedString = String.format("%1$s", getString(R.string.your_string));
I am developing the application which consists of AutoCompleteTextView,here is my problem,How I can upper case the letters entering in AutoCompleteTextView.
I Don't want in xml: android:capitalize="characters"
I want to declare in Java code.
You can try like this..In your text watcher in ontextchanged change the text to upper case..and check if the new string in edittext is the old string which you converted to upper case...in order to avoid stackoverflow error..
String upper = mytextview.getText().toString().toUpperCase()
mytextview.setText(upper);
Try this in your code there are some other flags also which you can check and try.
tv.setInputType(InputType.TYPE_TEXT_FLAG_CAP_CHARACTERS);
I am trying to add a line break in the TextView.
I tried suggested \n but that does nothing. Here is how I set my texts.
TextView txtSubTitle = (TextView)findViewById(r.id.txtSubTitle);
txtSubTitle.setText(Html.fromHtml(getResources().getString(R.string.sample_string)));
This is my String: <string name="sample_string">some test line 1 \n some test line 2</string>
It should show like so:
some test line 1
some test line 2
But it shows like so: some test line 1 some test line 2.
Am I missing something?
\n works for me, like this:
<TextView android:text="First line\nNext line"
ok figured it out:
<string name="sample_string"><![CDATA[some test line 1 <br />some test line 2]]></string>
so wrap in CDATA is necessary and breaks added inside as html tags
Android version 1.6 does not recognize \r\n.
Instead, use: System.getProperty("line.separator")
String s = "Line 1"
+ System.getProperty("line.separator")
+ "Line 2"
+ System.getProperty("line.separator");
Linebreaks (\n) only work if you put your string resource value in quotes like this:
<string name="sample_string">"some test line 1 \n some test line 2"</string>
It won't do linebreaks if you put it without quotes like this:
<string name="sample_string">some test line 1 \n some test line 2</string>
yes, it's that easy.
Tried all the above, did some research of my own resulting in the following solution for rendering linefeed escape chars:
string = string.replace("\\\n", System.getProperty("line.separator"));
Using the replace method you need to filter escaped linefeeds (e.g. '\\n')
Only then each instance of line feed '\n' escape chars gets rendered into the actual linefeed
For this example I used a Google Apps Scripting noSQL database (ScriptDb) with JSON formatted data.
Cheers :D
There are two ways around this.
If you use your string as a raw string, you need to use the newline
character. If you use it as html, e.g. by parsing it with Html.fromString,
the second variant is better.
1) Newline character \n
<string name="sample">This\nis a sample</string>
2) Html newline tag <br> or <br />
<string name="sample">This<br>is a sample</string>
This worked for me
android:text="First \n Second"
This worked for me, maybe someone will find out this helpful:
TextView textField = (TextView) findViewById(R.id.textview1);
textField.setText("First line of text" + System.getProperty("line.separator") + "Linija 2");
If you're using XML to declare your TextView use android:singleLine = "false" or in Java, use txtSubTitle.setSingleLine(false);
Used Android Studio 0.8.9. The only way worked for me is using \n.
Neither wrapping with CDATA nor <br> or <br /> worked.
I use the following:
YOUR_TEXTVIEW.setText("Got some text \n another line");
very easy : use "\n"
String aString1 = "abcd";
String aString2 = "1234";
mSomeTextView.setText(aString1 + "\n" + aString2);
\n corresponds to ASCII char 0xA, which is 'LF' or line feed
\r corresponds to ASCII char 0xD, which is 'CR' or carriage return
this dates back from the very first typewriters, where you could choose to do only a line feed (and type just a line lower), or a line feed + carriage return (which also moves to the beginning of a line)
on Android / java the \n corresponds to a carriage return + line feed, as you would otherwise just 'overwrite' the same line
As I know in the previous version of android studio uses separate lines " \n " code. But new one (4.1.2) uses "<br/" to separate lines. For example -
Old one:
<string name="string_name">Sample text 1 \n Sample text 2 </string>
New one:
<string name="string_name">Sample text 1 <br/> Sample text 2 </string>
Also you can add "<br/>" instead of \n.
It's HTML escaped code for <br/>
And then you can add text to TexView:
articleTextView.setText(Html.fromHtml(textForTextView));
Try to double-check your localizations.
Possible, you trying to edit one file (localization), but actually program using another, just like in my case. The default system language is russian, while I trying to edit english localization.
In my case, working solution is to use "\n" as line separator:
<string name="string_one">line one.
\nline two;
\nline three.</string>
You could also use the String-Editor of Android Studio, it automatically generates line brakes and stuff like that...
As Html.fromHtml deprecated I simply I used this code to get String2 in next line.
textView.setText(fromHtml("String1 <br/> String2"));
.
#SuppressWarnings("deprecation")
public static Spanned fromHtml(String html){
Spanned result;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
result = Html.fromHtml(html,Html.FROM_HTML_MODE_LEGACY);
} else {
result = Html.fromHtml(html);
}
return result;
}
The most easy way to do it is to go to values/strings (in your resource folder)
Declare a string there:
<string name="example_string">Line 1\Line2\Line n</string>
And in your specific xml file just call the string like
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/example_string" />
I found another method:
Is necessary to add the "android:maxWidth="40dp"" attribute.
Of course, it may not work perfectly, but it gives a line break.
\n was not working for me. I was able to fix the issue by changing the xml to text and building the textview text property like below.
android:text="Line 1
Line 2
Line 3
DoubleSpace"
Hopefully This helps those who have said that \n did not work for them.
I'm reading my text from a file, so I took a slightly different approach, since adding \n to the file resulted in \n appearing in the text.
final TextView textView = (TextView) findViewById(R.id.warm_up_view);
StringBuilder sb = new StringBuilder();
Scanner scanner = new Scanner(getResources().openRawResource(R.raw.warm_up_file));
while (scanner.hasNextLine()) {
sb.append(scanner.nextLine());
sb.append("\n");
}
textView.setText(sb.toString());
In my case, I solved this problem by adding the following:
android:inputType="textMultiLine"
Maybe you are able to put the lf into the text, but it doesn't display? Make sure you have enough height for the control. For example:
Correct:
android:layout_height="wrap_content"
May be wrong:
android:layout_height="10dp"
I feel like a more complete answer is needed to describe how this works more thoroughly.
Firstly, if you need advanced formatting, check the manual on how to use HTML in string resources.
Then you can use <br/>, etc. However, this requires setting the text using code.
If it's just plain text, there are many ways to escape a newline character (LF) in static string resources.
Enclosing the string in double quotes
The cleanest way is to enclose the string in double quotes.
This will make it so whitespace is interpreted exactly as it appears, not collapsed.
Then you can simply use newline normally in this method (don't use indentation).
<string name="str1">"Line 1.
Line 2.
Line 3."</string>
Note that some characters require special escaping in this mode (such as \").
The escape sequences below also work in quoted mode.
When using a single-line in XML to represent multi-line strings
The most elegant way to escape the newline in XML is with its code point (10 or 0xA in hex) by using its XML/HTML entity
or
. This is the XML way to escape any character.
However, this seems to work only in quoted mode.
Another method is to simply use \n, though it negatively affects legibility, in my opinion (since it's not a special escape sequence in XML, Android Studio doesn't highlight it).
<string name="str1">"Line 1.
Line 2.
Line 3."</string>
<string name="str1">"Line 1.\nLine 2.\nLine 3."</string>
<string name="str1">Line 1.\nLine 2.\nLine 3.</string>
Do not include a newline or any whitespace after any of these escape sequences, since that will be interpreted as extra space.
I would recommend querying the line.separator property, and using that whenever you want to add a line break.
Here is some sample code:
TextView calloutContent = new TextView(getApplicationContext());
calloutContent.setTextColor(Color.BLACK);
calloutContent.setSingleLine(false);
calloutContent.setLines(2);
calloutContent.setText(" line 1" + System.getProperty ("line.separator")+" line2" );
