How can I set the android preference summary text color?

Question

On my preference screen I have a preference that when clicked opens a color picker dialog. What I would like to do is when the user selects a color, that the text summary of the preference is displayed in that color.

I know I can have the summary set up like this, Currently <font color="#ff0000">this color</font> and have it display in that color. The problem is the color I am getting back is the android int color.

I could use the red(), green(), blue() methods and then convert those to Hex and then combine them into a string so I could set the summary text with the new value and that works: String colorString = String.format("#%02x%02x%02x",Color.red( defaultColor ), Color.green( defaultColor ), Color.blue( defaultColor )); I was just curious if there is an easier way to do this.

Thanks ahead of time.

OK what I ended up doing was using a Spannable. This takes the color as an integer.

Spannable summary = new SpannableString("Currently This Color");
summary.setSpan(new ForegroundColorSpan(color), 0, summary.length(), 0);
preference.setSummary(summary);

Use Html.fromHtml to style your text.

mPodFolderPref.setTitle(Html.fromHtml("<font color='red'>" +  mPodFolderPref.getTitle() + "</font>"));
mPodFolderPref.setSummary(Html.fromHtml("<font color='red'>" +  mPodFolderPref.getSummary() + "</font>"));

Html.fromHtml can do a lot for you.

Not sure why it's being downvoted but this is the simplest answer to the question and easiest to implement. – Mendhak Oct 11 '14 at 14:16
The .fromHtml-solution also allows you to change lots of attributes more than just the textcolor, such as to bold the text. Hence, it is the much more valuable answer for me. Upvoted. – MojioMS Jul 08 '16 at 19:06
Its depreciated. – Yetti99 Mar 23 '17 at 18:56
This works, but I think it doesn't work for ListPreference – android developer Aug 28 '18 at 13:39

All the above ways didn't help me. I ended up by extends the Prefernces class:

public class CustomListPreferences extends Preference {

    public CustomListPreferences(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomListPreferences(Context context) {
        super(context);
    }

    @Override
    protected void onBindView(View view) {
        super.onBindView(view);
       ((TextView)view.findViewById(android.R.id.summary)).setTextColor(getContext().get Resources().getColor(R.color.green));
    }

}

A bit late, but I found useful to write these self-contained methods:

private void setColorPreferencesTitle(EditTextPreference textPref, int color) {
    CharSequence cs     = (CharSequence) textPref.getTitle();
    String plainTitle   = cs.subSequence(0, cs.length()).toString();
    Spannable coloredTitle = new SpannableString (plainTitle);
    coloredTitle.setSpan( new ForegroundColorSpan(color), 0, coloredTitle.length(), 0 );
    textPref.setTitle(coloredTitle);
}

private void resetColorPreferencesTitle(EditTextPreference textPref) {
    CharSequence cs     = (CharSequence) textPref.getTitle();
    String plainTitle   = cs.subSequence(0, cs.length()).toString();
    textPref.setTitle(plainTitle);
}

Hi you can change the color of preference using Html.fromHtml().

ex : private String title = "" + "Set the SMS Send Limit" + "";

and add set this string from your android application like this .

CheckBoxPreference _test = (CheckBoxPreference)findPreference("text"); _test .setTitle(Html.fromHtml(title ));

follow this link for html view of android : http://www.androidpeople.com/tag/html-tags/

I am aware of that. However, like I said above, I have access to the color as an int which is how Android stores it. Not the RGB or ARGB strings. – Sean Oct 28 '10 at 20:42
