How do you change the textcolor of the list items

问题:

Hello I am trying to change the text color of the items in a list on a ListPreference pop up window. I have spent over an hour looking through all of the various style names but I can't find TextAppearance or anything that goes to this particular text. Thanks for your help!

You can't and you shouldn't. *Preference uses styles from com.android.internal.R.styleable which might be changed by manufactures. The idea of using the default ones is that every preference screen in your device look alike.

On the other hand you can try doing an Activity with android:theme="@android:style/Theme.Dialog" in your app's AndroidManifest and place a ListView styled as you want.

I don't really know which kind of View use ListPreference, probably it's something like TextView. If so than you could make smth like:

TextView textView;
String myString;
//....
SpannableString spanString=new SpannableString(myString);
spanString.setSpan(new ForegroundColorSpan(Color.RED), 0, myString.length(), Spanned.SPAN_INCLUSIVE_INCLUSIVE);
textView.setText(spanString);
