Display string with bold letters in Dialog message

问题

Let's say I had this:

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity())
    .setMessage("I want THIS word to be bold and the rest normal!")
    .create().show();

Is there any way to have Android apply formatting or bold font to parts of the text string?

回答1:

You can add a string to your strings.xml like this:

<string name="bold_message">I want <b>THIS</b> word to be bold and the rest normal!</string>

and then in your alert dialog just use setMessage(R.string.bold_message)

Using Spannable string is easy way

In your string.xml add

<string name = "bold_message"><![CDATA[<p>This want <b>THIS</b> word to bold and the rest normal!</p>]]></string>

In your alert dialog

.setMessage(Html.fromHtml(R.string.bold_message);

You must use custom dialogs . Default Android dialogs don't have any option to do this .
