How to reference a string array in XML of Android layout file

The closest I could find on S.O. is this but it doesn't answer it.
It specifies here how to make a resource reference for a string, i.e. #string/string_name but further down under String Array in the documentation, it gives no option under Resource Reference for referencing the string array in XML like it does further up for String.

It's unclear what element you are trying to load the array into...
ListView has android:entries that accepts #array/ resource.
However, I find that adding adapters in the code makes more sense.
ArrayAdapter.createFromResource allows you to use an a String Array XML resource to load either a Spinner or a ListView using R.array in Java code.

How to access values from "strings.xml" dynamically in android?

App version 2.3.3
Here is what i am looking for...
I have few strings in "values/strings.xml". I wish to retrieve the values depending on the string's "name" attribute and use it my application. The input to which string in the xml should be used comes dynamically. Here is an example...
My input from other file :: "A" => This value changes. It can be any value in A,B,C,D.
I have different strings in strings.xml, like...
<string name="A">AforApple</string>
<string name="B">BforBall</string>
<string name="C">CforCat</string>
<string name="D">DforDog</string>
Now, how do i programmatically get the value(AforApple) of the String with name="A".

String str = context.getResources().getString(R.string.A)
or u can use
textBox.setText(R.string.A);
do not forget to import the package com.yourpackackage.R.

You need to use getResources() method:
String a = getResources().getString(R.string.A);

Just for the record, you can also dynamically generate it using reflection.
int stringRes=R.string.class.getField("Here you put the dynamically generated input, such as A").getInt(null);
textView.setText(stringRes);
This will return the resource int value from string XML based on the input, as long as the input value "A" matches string name in the XML, this will retrieve them dynamically.

To access a String resource/value that you’ve defined in an XML file from your Android/Java code, use the Android getString method, like this:
String A = getString(R.string.a_string);

If your code gets a string like "A" and you are trying to dynamically find the string in your resources that matches that name, I don't think you can do that.
Instead of using the strings.xml, you might want to use arrays.xml and build a HashMap from that before you need to access those strings

Try this:
String word = getResources().getString(R.string.A);
Check out the link here.

You can use this code:
getText(R.string.A);
Basically, you need to pass the resource id as a parameter to the getText() method.

Android: how to put question mark in a string resource?

Android doesn't allow strings containing '?' because it has special meaning in XML context. How do I encode this symbol in a string resource?

Use a backslash.

Set values to text identifier by var name. An alternative to getIdentifier

I am trying to set String values for ids defined in xmls. I have defined the set of text which can be assigned to different ids in the layout xml files. Thereby I can also see the int values that are associated with different texts in R.java.
I have stored the variable names that I have given to the texts in my database along with the R.id prefix as they appear in R.java file.
For setting text,
TextView messageone = (TextView)findViewById(R.id.textfield1);
Normal Usage:
String message = "Hi, hello";
messageone.setText(Status);
What i want to implement:
public static final int messagestring is present in R.java
R.id.messagestring is stored in sqlite database in text format
messageone.setText(what_here);
what_here = a way to get the value from "R.id.messagestring" string as obtained from database.
I know public int getIdentifier (String name, String defType, String defPackage)
can be used here. The only change would be stored text in database will change from R.id.messagestring to messagestring. But there is a note discouraging this type of implementation.
It says: use of this function is discouraged. It is much more efficient to retrieve resources by identifier than by name.
Android Docs getIdentifier
I think although this method seems like a longer implementation, can be efficient when the objects dealt with are not text.

There's a getString(int Id) method you can use inside an Activity. It will return a String from a given R.string Id.
String something = getString(R.string.something);
I hope I helped out a bit here, because I'm not entirely sure if I understand your question.

Show a bulleted list from Strings.xml file in android

I have a problem that I want to show a bulleted list contents which is resided in strings.xml file as an array elements. Then the problem is that how to convert the array elements in Html List format? Can any one suggest any solution regarding the same.
Thanks in advance

I just put the symbol directly into the strings.xml without any codes or anything:
<string name="msg_sms_no_note">• Notes and attachments will not be sent.</string>

There's a problem with the approach suggested by some of the answers in this thread of prepending the bullet unicode character (i.e. \u2022) to each of the Strings in the String array: You don't get proper indentation when one or more Strings in the String array span multiple lines. What you get is formatting as follows:
In order to get proper indentation, you're better using BulletSpan. In doing so, you'll get formatting as follows:
To use BulletSpan, you need to create a SpannableStringBuilder instance and append each String in your String array to this SpannableStringBuilder instance. As you append each String, call the setSpan(what:start:end:flags:) method on the SpannableStringBuilder instance passing in a BulletSpan instance for the what parameter. You can find an example of this in the appendBulletSpan(...) Kotlin extension function located here.

I think, the most elegant way of doing this is to load a WebView and put your string in it. this way, you use the common ul/li convention and you can style it at your leisure with CSS.

Use the unicode escape sequence "\u2022" in strings.xml
like so:
<string name="menu_new_trip_desc">View them in: \n\u2022 Table
