You could basically use html tags in your string resource like:
<resource>
<string name="styled_welcome_message">We are <b><i>so</i></b> glad to see you.</string>
</resources>
And use Html.fromHtml or use spannable, check the link I posted.

Solution 2 - Java
Use html tag inside string resources :-
<resources>
<string name="string_resource_name"><![CDATA[<b> Your text </b>]]> </string>
</resources>
And get bold text from string resources like :-
private Spanned getSpannedText(String text) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
return Html.fromHtml(text, Html.FROM_HTML_MODE_COMPACT);
} else {
return Html.fromHtml(text);
}
}
String s = format(context.getResources().getString(R.string.string_resource_name));
textView.setText(getSpannedText(s));
Solution 3 - Java
As David Olsson has said, you can use HTML in your string resources:
<resource>
<string name="my_string">A string with <i>actual</i> <b>formatting</b>!</string>
</resources>
Then if you use getText(R.string.my_string)
rather than getString(R.string.my_string)
you get back a CharSequence
rather than a String
that contains the formatting embedded.
Solution 4 - Java
In kotlin, you can create extensions functions on resources (activities|fragments |context) that will convert your string to an html span
e.g.
fun Resources.getHtmlSpannedString(@StringRes id: Int): Spanned = getString(id).toHtmlSpan()
fun Resources.getHtmlSpannedString(@StringRes id: Int, vararg formatArgs: Any): Spanned = getString(id, *formatArgs).toHtmlSpan()
fun Resources.getQuantityHtmlSpannedString(@PluralsRes id: Int, quantity: Int): Spanned = getQuantityString(id, quantity).toHtmlSpan()
fun Resources.getQuantityHtmlSpannedString(@PluralsRes id: Int, quantity: Int, vararg formatArgs: Any): Spanned = getQuantityString(id, quantity, *formatArgs).toHtmlSpan()
fun String.toHtmlSpan(): Spanned = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Html.fromHtml(this, Html.FROM_HTML_MODE_LEGACY)
} else {
Html.fromHtml(this)
}
Usage
//your strings.xml
<string name="greeting"><![CDATA[<b>Hello %s!</b><br>]]>This is newline</string>
//in your fragment or activity
resources.getHtmlSpannedString(R.string.greeting, "World")
EDIT even more extensions
fun Context.getHtmlSpannedString(@StringRes id: Int): Spanned = getString(id).toHtmlSpan()
fun Context.getHtmlSpannedString(@StringRes id: Int, vararg formatArgs: Any): Spanned = getString(id, *formatArgs).toHtmlSpan()
fun Context.getQuantityHtmlSpannedString(@PluralsRes id: Int, quantity: Int): Spanned = resources.getQuantityString(id, quantity).toHtmlSpan()
fun Context.getQuantityHtmlSpannedString(@PluralsRes id: Int, quantity: Int, vararg formatArgs: Any): Spanned = resources.getQuantityString(id, quantity, *formatArgs).toHtmlSpan()
fun Activity.getHtmlSpannedString(@StringRes id: Int): Spanned = getString(id).toHtmlSpan()
fun Activity.getHtmlSpannedString(@StringRes id: Int, vararg formatArgs: Any): Spanned = getString(id, *formatArgs).toHtmlSpan()
fun Activity.getQuantityHtmlSpannedString(@PluralsRes id: Int, quantity: Int): Spanned = resources.getQuantityString(id, quantity).toHtmlSpan()
fun Activity.getQuantityHtmlSpannedString(@PluralsRes id: Int, quantity: Int, vararg formatArgs: Any): Spanned = resources.getQuantityString(id, quantity, *formatArgs).toHtmlSpan()
fun Fragment.getHtmlSpannedString(@StringRes id: Int): Spanned = getString(id).toHtmlSpan()
fun Fragment.getHtmlSpannedString(@StringRes id: Int, vararg formatArgs: Any): Spanned = getString(id, *formatArgs).toHtmlSpan()
fun Fragment.getQuantityHtmlSpannedString(@PluralsRes id: Int, quantity: Int): Spanned = resources.getQuantityString(id, quantity).toHtmlSpan()
fun Fragment.getQuantityHtmlSpannedString(@PluralsRes id: Int, quantity: Int, vararg formatArgs: Any): Spanned = resources.getQuantityString(id, quantity, *formatArgs).toHtmlSpan()

Strings.xml
<string name="my_text"><Data><![CDATA[<b>Your text</b>]]></Data></string>
To set
textView.setText(Html.fromHtml(getString(R.string.activity_completed_text)));
Solution 6 - Java
You can do it from string
<resources xmlns:tools="http://schemas.android.com/tools">
<string name="total_review"><b>Total Review: </b> </string>
</resources>
and can access it from the java code like
proDuctReviewNumber.setText(getResources().getString(R.string.total_review)+productDetailsSuccess.getProductTotalReview());
Solution 7 - Java
In Kotlin I have created an extension function for the Context. It takes a @StringRes and optionally you can provide parameters as well.
fun Context.fromHtmlWithParams(@StringRes stringRes: Int, parameter : String? = null) : Spanned {
val stringText = if (parameter.isNullOrEmpty()) {
this.getString(stringRes)
} else {
this.getString(stringRes, parameter)
}
return Html.fromHtml(stringText, Html.FROM_HTML_MODE_LEGACY)
}
Usage
tv_directors.text = context?.fromHtmlWithParams(R.string.directors, movie.Director)
Solution 8 - Java
here it's the solution for if there have any assigned values inside the string.xml file.
<string name="styled_welcome_message"><![CDATA[We are <b> %1$s </b> glad to see you.]]></string>
set in to TextView:
textView?.setText(HtmlCompat.fromHtml(getString(R.string.styled_welcome_message, "sample"), HtmlCompat.FROM_HTML_MODE_LEGACY), TextView.BufferType.SPANNABLE)
PS: don't forget to wrap your text (in String Resources) within:
<![CDATA[ YOUR TEXT HERE ]]>
Solution 9 - Java
strings.xml
<string name="sentence">This price is <b>%1$s</b> USD</string>
page.java
String successMessage = getText(R.string.message,"5.21");
This price 5.21 USD
Solution 10 - Java
I was having a text something like:
Forgot Password? Reset here.
To implement this the easy way I used the existing android:textStyle="bold"
<LinearLayout
android:id="@+id/forgotPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:autoLink="all"
android:linksClickable="false"
android:selectAllOnFocus="false"
android:text="Forgot password? "
android:textAlignment="center"
android:textColor="@android:color/white"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:autoLink="all"
android:linksClickable="false"
android:selectAllOnFocus="false"
android:text="Reset here"
android:textAlignment="center"
android:textColor="@android:color/white"
android:textStyle="bold" />
</LinearLayout>

If you want to store formatted as a string variable and reuse it to text view isn't possible
> If you aren't applying formatting, you can set TextView text directly > by calling setText(java.lang.CharSequence). In some cases, however, > you may want to create a styled text resource that is also used as a format string. Normally, this doesn't work because the > format(String, Object...) and getString(int, Object...) methods > strip all the style information from the string. The work-around to this is to write the HTML tags with escaped entities, which are > then recovered with fromHtml(String), after the formatting takes > place.
by from docs so alternatively store the string id and everyttime bind get string from using Htlm.fromHtml().. method.
ex:
Kotlin extention
fun Context.getStringFromResource(stringId: Int): Spanned {
return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Html.fromHtml(java.lang.String.format(resources.getString(stringId)),
Html.FROM_HTML_MODE_COMPACT)
} else {
Html.fromHtml(java.lang.String.format(resources.getString(stringId)))
}
}
In code:
getStringFromResource(id)
Solution 12 - Java
If you want to use basic HTML tags in a string resource, it is necessary to escape the tags, otherwise they are ignored. Simply, replace '<' with < and '>' with '>' e.g:
<string name="bold_statement">This is a <bold> statement</string>
Will produce: This is a bold statement. When loading the String resource, make sure to use
HtmlCompat.fromHtml(stringFromResource, HtmlCompat.FROM_HTML_MODE_COMPACT)
