Here s a good article on how to use selectors with lists   Instead of setting it to be the android background of the ListView  I believe you want to set android listSelector as shown below    lt ListView android id    id list     android layout width  fill parent    android layout height  wrap content     android layout gravity  center    android divider   null     android dividerHeight  0dip    android listSelector   drawable list selector    gt

The child views in your list row should be considered selected whenever the parent row is selected  so you should be able to just set a normal state drawable color-list on the views you want to change  no messy Java code necessary  See this SO post   Specifically  you d set the textColor of your textViews to an XML resource like this one    lt  xml version  1 0  encoding  utf-8   gt   lt selector xmlns android  http   schemas android com apk res android  gt       lt item android state focused  true  android drawable   color black    gt   lt  -- focused -- gt       lt item android state focused  true  android state pressed  true  android drawable   color black    gt   lt  -- focused and pressed-- gt       lt item android state pressed  true  android drawable   color green    gt   lt  -- pressed -- gt       lt item android drawable   color black    gt   lt  -- default -- gt   lt  selector gt

Very old but I have just struggled with this  this is how I solved it in pure xml   In res values colors xml I added three colours  the colour         lt resources gt        lt color name  black overlay  gt  66000000 lt  color gt        lt color name  colour highlight grey  gt  ff666666 lt  color gt       lt color name  colour dark blue  gt  ff000066 lt  color gt       lt color name  colour dark green  gt  ff006600 lt  color gt    lt  resources gt    In the res drawable folder I created listview colours xml which contained    lt  xml version  1 0  encoding  utf-8   gt   lt selector xmlns android  http   schemas android com apk res android  gt       lt item android drawable   color colour highlight grey  android state pressed  true   gt       lt item android drawable   color colour dark blue  android state selected  true   gt       lt item android drawable   color colour dark green  android state activated  true   gt       lt item android drawable   color colour dark blue  android state focused  true   gt   lt  selector gt    In the main activity xml find the List View and add the drawable to listSelector    lt ListView     android id    id menuList      android layout width  match parent      android layout height  match parent      android listSelector   drawable listview colours      android background   ff222222   gt   lt  LinearLayout gt    Play with the state     items in the listview colours xml to get the effect you want   There is also a method where you can set the style of the List View but I never managed to get it to work

Declare list item components as final outside your setOnClickListener or whatever you want to apply on your list item like this   final View yourView  final TextView yourTextView    And in overriding onClick or whatever method you use  just set colors as needed like this      yourView setBackgroundColor Color WHITE  or whatever RGB suites good contrast     yourTextView setTextColor Color BLACK  or whatever RGB suites good contrast       Or without the final declaration  if let s say you implement an onClick   for a custom adapter to populate a list  this is what I used in getView   for my setOnClickListener onClick       reset color for all list items in case any item was previously selected for int i   0  i  lt  parent getChildCount    i        parent getChildAt i  setBackgroundColor Color BLACK     TextView text  TextView  parent getChildAt i  findViewById R id item     text setTextColor Color rgb 0 178 178        highlight currently selected item  parent getChildAt position  setBackgroundColor Color rgb 0 178 178     TextView text  TextView  parent getChildAt position  findViewById R id item    text setTextColor Color rgb 0 178 178
