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.
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);
}
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));
}
}
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/
Thanks
