How to set part of text to bold when using AlertDialog.setMessage() in Android?

Question

How to set part of text to Bold when using AlertDialog\'s setMessage()? Adding and to my Strin

Answer 1

In case if anyone wants to add only a single string:

<string name="abouttxt">&lt;b>Enter license key&lt;/b></string>

Add this line in your Alertdialog code.

dialog.setTitle(Html.fromHtml(getString(R.string.abouttxt)))

Answer 2

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>"));
}

Answer 3

This page describes how to add HTML formatting to resource strings.

<resources>
    <string name="welcome_messages">Hello, %1$s! You have &lt;b>%2$d new messages&lt;/b>.  
    </string>
</resources>

And do not forget to use: Html.fromHtml

AlertDialog.setMessage(Html.fromHtml(getString(R.string.welcome_messages)));

This works for me
