android - Changing the highlight and title color for fragments in PreferenceActivity -



android - Changing the highlight and title color for fragments in PreferenceActivity -

i'm using material theme, , i'd alter color of 2 marked areas in image below - i.e. highlight color (#1) , color of title in details fragment (#2).

i know there's attribute color of each somewhere in theme, can't seem find it.

any ideas?

i know there's attribute color of each somewhere in theme, can't seem find it.

item number 1

the attribute you'll want activatedbackgroundindicator.

as per docs

drawable used background activated items.

reason being

the layout used each header item in preferenceactivity preference_header_item_material uses activatedbackgroundindicator background. you'll need selector attribute, like:

<selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_activated="true"><color android:color="yourcolor" /> </item> <item><color android:color="@android:color/transparent" /> </item> </selector> item number 2

this item trickier. it's not preferencescreen suggested in other answer, fragmentbreadcrumbs title. unfortunately, title color cannot set using theme because attribute used style private internal.

you can set text color using reflection or traversing breadcrumb's view hierarchy until find textview used display title.

the layout used display content in each preferenceactivity preference_list_content_material includes breadcrumbs_in_fragment_material layout display each breadcrumb. can see layout id of each fragmentbreadcrums android:id/title. can utilize id find breadcrumb , adjust the textview within it.

using reflection

@override public void onbuildheaders(list<header> target) { super.onbuildheaders(target); loadheadersfromresource(r.xml.yourpreferenceheaders, target); final view breadcrumb = findviewbyid(android.r.id.title); if (breadcrumb == null) { // single pane layout return; } seek { final field titlecolor = breadcrumb.getclass().getdeclaredfield("mtextcolor"); titlecolor.setaccessible(true); titlecolor.setint(breadcrumb, yourtitlecolor); } grab (final exception ignored) { // nil } }

traversing view hierarchy

using view.findviewswithtext easy way handle this.

breadcrumb.getviewtreeobserver().addongloballayoutlistener(new ongloballayoutlistener() { @override public void ongloballayout() { breadcrumb.getviewtreeobserver().removeongloballayoutlistener(this); final arraylist<view> outviews = lists.newarraylist(); breadcrumb.findviewswithtext(outviews, getstring(r.string.your_header_title), view.find_views_with_text); ((textview) outviews.get(0)).settextcolor(yourtitlecolor); } }); results
