I am using takephoto_library for selecting multiple images.
https://github.com/crazycodeboy/TakePhoto
It is working properly but as you can see in the below screenshot, the caption is in Chinese.
I found that the view control is "com.darsh.multipleimageselect.activities" and Id of this caption is in the below
actionBar.setTitle(R.string.album_view);
Is there any way to change this string to English?

Yes, you can change all the Strings in strings.xml
https://github.com/crazycodeboy/TakePhoto/blob/master/takephoto_library/src/main/res/values/strings.xml
Change these two chinese word to english
<string name="add">确定</string>
<string name="selected">已选</string>
In English
<string name="add">confirm</string>
<string name="selected">selected</string>
Try this .
find the strings.xml(values) and strings.xml(values-en) in the library of TakePhoto .
And change the string name to the English .
In the strings.xml(values)
string name="add">确定</string>
<string name="selected">已选</string>
<string name="limit_exceeded">最多能选 %d 张</string>
And add this to the strings.xml(values-en)
string name="add">confirm</string>
<string name="selected">selected</string>
<string name="limit_exceeded">You can choose%d at most</string>
And you can change this strings.xml(values-en) and strings.xml(values)
For internationalization, android looks in different directories for the appropriate local as determined by your selection for the phone. For instance, you should see something like this:
./explorer/src/main/res/values-uk/strings.xml
./explorer/src/main/res/values-tr/strings.xml
./explorer/src/main/res/values-ru/strings.xml
./explorer/src/main/res/values-pl/strings.xml
./explorer/src/main/res/values-de/strings.xml
./explorer/src/main/res/values-ko/strings.xml
./explorer/src/main/res/values-sv/strings.xml
...
Where the translated strings are in the values-../strings as determined by the res/values/strings.xml.
In my case, res/values/strings.xml has an entry:
<string name="createnewfolder">Create new folder</string>
which is translated in values-uk/strings.xml as
<string name="createnewfolder">Нова папка</string>
You might find Localizing with Resources useful.
Is there a way to set the value of an xml string tag value to include that of another string tag value. The idea is like this:
<string name="tag1">"this is"</string>
<string name="tag2"><tag1 + " what I mean"</string>
Is this possible and if so how do I do it?

Arithmetic, concatenation operations are not possible in android resource files.
You can concatenate strings without writing any Java/Kotlin code, only XML by using this small library I created which does so at buildtime: https://github.com/LikeTheSalad/android-stem
Usage
Based on your example, you'd have to set your strings like this:
<string name="tag1">this is</string>
<string name="tag2">${tag1} what I mean</string>
And then after building your project, you'll get:
<!-- Auto generated during compilation -->
<string name="tag2">this is what I mean</string>
In my Android app I'm using strings.xml for all texts. I have many situations where I use almost the same string,
e.g. "Name" and "Name:" - translation is the same only additional colon is difference.
Is there any other way to have these two string except creating two string items like this:
<string name="name">Name</string>
<string name="name2">Name:</string>
There is no way you can concatenate strings in the strings.xml file.
All you can do is specify the format,
<string name="name">Name</string>
<string name="string_with_colon">%s:</string>
Then pass the name programatically,
String.format(getString(R.string.string_with_colon), getString(R.string.name));

Is it possible to use an integer:
<integer name="minstringlength">7</integer>
within the same resource file but within a string:
<string name="nametooshort">Please enter a name longer than #integer/minstringlength characters</string>
I presume you want to use different minimum limits based on device configuration. You can't use the #integer/minstringlength in the string content, so I think the best you can do is have a format argument and build the string yourself like this:
<integer name="minstringlength">7</integer>
<string name="nametooshort">Please enter a name longer than %1$d characters</string>
int nameMinLength = getResources.getInt(R.integer.minstringlength, 0);
String nametooshort = getString(R.string.nametooshort, nameMinLength);
This assumes you are using an Activity/Fragment, otherwise you need a Context in order to use getResources() and getString().
It can not be done in resource file.
As xml contains static content and also from android string-resource doc there is no sub tag or nested tag of <string>
It task can done easily in java file
getResources().getString(R.string.minstringlength);
getResources().getInteger(R.integer.nametooshort);
OR
Follow this post
<string name="meatShootingMessage">You shot %1$d pounds of meat!</string>
int numPoundsMeat = 123;
String strMeatFormat = getResources().getString(R.string.meatShootingMessage);
String strMeatMsg = String.format(strMeatFormat, numPoundsMeat);
Is it possible to have placeholders in string values in string.xml that can be assigned values at run time?
Example:
some string PLACEHOLDER1 some more string
Formatting and Styling
Yes, see the following from String Resources: Formatting and Styling
If you need to format your strings using String.format(String, Object...), then you can do so by putting your format arguments in the string resource. For example, with the following resource:
<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>
In this example, the format string has two arguments: %1$s is a string and %2$d is a decimal number. You can format the string with arguments from your application like this:
Resources res = getResources();
String text = String.format(res.getString(R.string.welcome_messages), username, mailCount);
Basic Usage
Note that getString has an overload that uses the string as a format string:
String text = res.getString(R.string.welcome_messages, username, mailCount);
Plurals
If you need to handle plurals, use this:
<plurals name="welcome_messages">
<item quantity="one">Hello, %1$s! You have a new message.</item>
<item quantity="other">Hello, %1$s! You have %2$d new messages.</item>
</plurals>
The first mailCount param is used to decide which format to use (single or plural), the other params are your substitutions:
Resources res = getResources();
String text = res.getQuantityString(R.plurals.welcome_messages, mailCount, username, mailCount);
See String Resources: Plurals for more details.
Supplemental Answer
When I first saw %1$s and %2$d in the accepted answer, it made no sense. Here is a little more explanation.
They are called format specifiers. In the xml string they are in the form of
%[parameter_index$][format_type]
%: The percent sign marks the beginning of the format specifier.
parameter index: This is a number followed by a dollar sign. If you had three parameters that you wanted to insert into the string, then they would be called 1$, 2$, and 3$. The order you place them in the resource string doesn't matter, only the order that you supply the parameters.
format type: There are a lot of ways that you can format things (see the documentation). Here are some common ones:
s string
d decimal integer
f floating point number
Example
We will create the following formatted string where the gray parts are inserted programmatically.
My sister Mary is 12 years old.
string.xml
<string name="my_xml_string">My sister %1$s is %2$d years old.</string>
MyActivity.java
String myString = "Mary";
int myInt = 12;
String formatted = getString(R.string.my_xml_string, myString, myInt);
Notes
I could use getString because I was in an Activity. You can use context.getResources().getString(...) if it is not available.
String.format() will also format a String.
The 1$ and 2$ terms don't need to be used in that order. That is, 2$ can come before 1$. This is useful when internationalizing an app for languages that use a different word order.
You can use a format specifier like %1$s multiple times in the xml if you want to repeat it.
Use %% to get the actual % character.
For more details read the following helpful tutorial: Android SDK Quick Tip: Formatting Resource Strings
When you want to use a parameter from the actual strings.xml file without using any Java code:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE resources [
<!ENTITY appname "WhereDat">
<!ENTITY author "Oded">
]>
<resources>
<string name="app_name">&appname;</string>
<string name="description">The &appname; app was created by &author;</string>
</resources>
This does not work across resource files, i.e. variables must be copied into each XML file that needs them.
Was looking for the same and finally found the following very simple solution. Best: it works out of the box.
1. alter your string ressource:
<string name="welcome_messages">Hello, <xliff:g name="name">%s</xliff:g>! You have
<xliff:g name="count">%d</xliff:g> new messages.</string>
2. use string substitution:
c.getString(R.string.welcome_messages,name,count);
where c is the Context, name is a string variable and count your int variable
You'll need to include
<resources xmlns:xliff="http://schemas.android.com/apk/res-auto">
in your res/strings.xml.
Works for me. :)
If you want to write percent (%), duplicate it:
<string name="percent">%1$d%%</string>
label.text = getString(R.string.percent, 75) // Output: 75%.
If you write simply %1$d%, you will get the error: Format string 'percent' is not a valid format string so it should not be passed to String.format.
Or use formatted=false" instead.
In Kotlin you just need to set your string value like this:
<string name="song_number_and_title">"%1$d ~ %2$s"</string>
Create a text view on your layout:
<TextView android:text="#string/song_number_and_title"/>
Then do this in your code if you using Anko:
val song = database.use { // get your song from the database }
song_number_and_title.setText(resources.getString(R.string.song_number_and_title, song.number, song.title))
You might need to get your resources from the application context.
In your string file use this
<string name="redeem_point"> You currently have %s points(%s points = 1 %s)</string>
And in your code use as accordingly
coinsTextTV.setText(String.format(getContext().getString(R.string.redeem_point), rewardPoints.getReward_points()
, rewardPoints.getConversion_rate(), getString(R.string.rs)));
However, you should also read Elias Mårtenson's answer on Android plurals treatment of “zero”. There is a problem with the interpretation of certain values such as "zero".
For Multilingual Projects
As someone who has worked on a major white label solution with many and varying languages and configurations per variant, I can say that there's a lot to consider.
Text direction aside, grammar alone can give you some headaches.
For instance can the order of items change thus
<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>
is to be preferred over
<string name="welcome_messages">Hello, %s! You have %d new messages.</string>
but once you work with translators who often don't know what a string or an integer is, let alone what formatting character to use for each type, or people in general who have no idea in what order the parameters are applied in your code, or even you yourself forget that, or things change which then must be updated at multiple places at once, so using MessageFormat like
<string name="welcome_message">Hello, {0}! You have {1} new messages.</string>
MessageFormat(R.string.welcome_message).format("Name", numMessages)
isn't viable either and the idea of having non tech people try to figure out xlift can't even be entertained then the best solution I know so far is to use explicit, named placeholders as such
<string name="placeholder_data" translatable="false">DATA</string>
<string name="placeholder_data" translatable="false">$DATA</string>
<string name="placeholder_data" translatable="false">%DATA%</string>
..or whatever else doesn't conflict with your texts.
And while you could use DOCTYPE like
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE resources [
<!ENTITY placeholder_data "$DATA">
]>
<string name="text_with_data">Your data is &placeholder_data;.</string>
this will not work with separate files for each language.
Thus in your main/res/values/strings.xml provide the placeholders and default strings like this
<resources>
<string name="placeholder_data" translatable="false">$DATA</string>
<string name="placeholder_error" translatable="false">$ERROR</string>
<string name="app_name">The App</string>
<string name="content_loading">loading..</string>
<string name="content_success">success: $DATA</string>
<string name="content_error">error: $ERROR</string>
</resources>
and then in your variant variant/res/values-de/strings.xml
<resources>
<string name="app_name">Die Applikation</string>
<string name="content_loading">Ladevorgang..</string>
<string name="content_success">Erfolg: $DATA</string>
<string name="content_error">Netzwerkkommunikationsfehler: $ERROR</string>
</resources>
and to use it, write something like
textView.text = when (response) {
is Data -> getText(content_success).resolveData(response.data)
is Error -> getText(content_error).resolveError(response.error)
is Loading -> getText(content_loading)
}
with the use of some helper functions like
fun CharSequence.resolveData(data: JsonObject) =
toString().replace(getString(placeholder_data), data.toString())
fun CharSequence.resolveError(error: Throwable) =
toString().replace(getString(placeholder_error), error.toString())
for simply the reason of having a reference for the translation files and development. Hence there should not be a default file per build flavor. Only the single default file and then a file per language x variant.
Now there's also the issue of numeric grammar. This can be solved with plurals but here again the complexity of the xml file increases. And, as pointed out, zero does not work as one would expect. But also you may want to have a limit to which your app counts due to display size limitations or number of pre-rendered images for your UI and need to display 99+ instead of 100. A solution would be to use a helper function like
fun Context.getText(
quantity: Int,
#PluralsRes resIdQuantity: Int,
#StringRes resIdNone: Int? = null,
#StringRes resIdMoreThan: Int? = null,
maxQuantity: Int? = null,
): CharSequence {
if (resIdMoreThan != null && maxQuantity != null && quantity > maxQuantity)
return getText(resIdMoreThan)
return if (resIdNone != null && quantity == 0) return getText(resIdNone)
else resources.getQuantityText(resIdQuantity, quantity)
}
to override and extend the behavior of the plurals resolver.
And if you have optional features per variant then add a res/values/strings-beans.xml like:
<resources>
<string name="placeholder_name" translatable="false">$NAME</string>
<string name="placeholder_count" translatable="false">$COUNT</string>
<string name="beans_content_bean_count_zero">Hello $NAME! You have no beans.</string>
<string name="beans_content_bean_count_one">Hello $NAME! You have one bean.</string>
<string name="beans_content_bean_count_many">Hello $NAME! You have $COUNT beans.</string>
<string name="beans_content_bean_count_more_than_9000">Hello $NAME! You have over $COUNT beans!</string>
<string name="beans_content_bean_count_two">#string/beans_content_bean_count_many</string>
<string name="beans_content_bean_count_few">#string/beans_content_bean_count_many</string>
<string name="beans_content_bean_count_other">#string/beans_content_bean_count_many</string>
<plurals name="beans_content_bean_count">
<item quantity="zero">#string/beans_content_bean_count_zero</item>
<item quantity="one">#string/beans_content_bean_count_one</item>
<item quantity="two">#string/beans_content_bean_count_two</item>
<item quantity="few">#string/beans_content_bean_count_few</item>
<item quantity="many">#string/beans_content_bean_count_many</item>
<item quantity="other">#string/beans_content_bean_count_other</item>
</plurals>
</resources>
while the variant in variant-with-beans/res/value-en/strings-beans.xml only needs to contain
<resources>
<string name="beans_content_bean_count_zero">Hello $NAME! You have no beans.</string>
<string name="beans_content_bean_count_one">Hello $NAME! You have one bean.</string>
<string name="beans_content_bean_count_many">Hello $NAME! You have $COUNT beans.</string>
<string name="beans_content_bean_count_more_than_9000">Hello $NAME! You have over 9000 beans!</string>
</resources>
and language specific overrides can be provided on a per file basis.
To use this, the code can look like this
val name = "Bob"
val beanCount = 3
val limit = 9000
text = getText(
beanCount,
beans_content_bean_count,
beans_content_bean_count_zero,
beans_content_bean_count_more_than_9000,
limit,
)
.resolveCount(beanCount)
.resolveName(name)
which resolves to the outputs
beanCount = 0 -> "Hello Bob! You have no beans."
beanCount = 1 -> "Hello Bob! You have one bean."
beanCount = 3 -> "Hello Bob! You have 3 beans."
beanCount = 9001 -> "Hello Bob! You have over 9000 beans!"
and due to the resulting simplicity of the language specific resource files, they then can be generated with deployment tools from spread sheets or your company's own server endpoints, etc.
I hope you enjoyed my maddening ride into the world of dynamic string resources for Android and hopefully appreciate that you're not the poor fools having to get the same functionality to work on the iOS side of the product which from my experience required python scripts to modify .xcodeproj files and generate swift code.
in res/values/string.xml
<resources>
<string name="app_name">Hello World</string>
<string name="my_application">Application name: %s, package name: %s</string>

String[] args = new String[2];
args[0] = context.getString(R.string.app_name);
args[1] = context.getPackageName();
String textMessage = context.getString(R.string.my_application,(Object[]) args);
You can use MessageFormat:
<string name="customer_address">Wellcome: {0} {1}</string>
In Java code :
String text = MessageFormat(R.string.customer_address).format("Name","Family");
