's setMessage()
? Adding <b>

doesn't work.
Java Solutions
Solution 1 - Java
You need to use Html.fromHtml()
too. For example:
AlertDialog.setMessage(Html.fromHtml("Hello "+"<b>"+"World"+"</b>"));
Update:
Looks like Html.fromHtml(String source)
has been deprecated in the Latest Android Nougat version. Although deprecation doesn't mean that you need to change your code now, but it's a good practice to remove deprecated code from your app as soon as possible.
The replacement is Html.fromHtml(String source, int flags)
. You just need to add an additional parameter mentioning a flag.
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
AlertDialog.setMessage(Html.fromHtml("Hello "+"<b>"+"World"+"</b>", Html.FROM_HTML_MODE_LEGACY));
} else {
@Suppress("DEPRECATION")
AlertDialog.setMessage(Html.fromHtml("Hello "+"<b>"+"World"+"</b>"));
}

Solution 2 - Java
This page describes how to add HTML formatting to resource strings.
<resources>
<string name="welcome_messages">Hello, %1$s! You have <b>%2$d new messages</b>.
</string>
</resources>
And do not forget to use: Html.fromHtml
AlertDialog.setMessage(Html.fromHtml(getString(R.string.welcome_messages)));
This works for me
Solution 3 - Java
None of these solutions worked for me, but I am required to use an older version of the API so I could not use Html.fromHtml
. To bold part of the text for an AlertDialog
I had to use a SpannableString
.
String msgPart1 = getString(R.string.PartOneOfMessage);
SpannableString msg = new SpannableString(msgPart1 + " " + boldTextString + " " + getString(R.string.PartTwoOfMessage));
msg.setSpan(new StyleSpan(Typeface.BOLD), msgPart1.length() + 1, msgPart1.length() + datumName.length() + 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
AlertDialog.setMessage(msg);
I am not saying this is the best way, but it was the way that worked for me.
Solution 4 - Java
<string name="abouttxt">"<b>Info</b>\ntexttxtxtxtxt"</string>
this works for me in xml
Solution 5 - Java
In case if anyone wants to add only a single string:
<string name="abouttxt"><b>Enter license key</b></string>
Add this line in your Alertdialog code.
dialog.setTitle(Html.fromHtml(getString(R.string.abouttxt)))
