If you want to use a color from colors xml   experiment       public View getView int position  View convertView  ViewGroup parent                         View rowView   inflater inflate this rowLayoutID  parent  false           rowView setBackgroundColor rowView getResources   getColor R color my bg color            TextView title    TextView  rowView findViewById R id txtRowTitle           title setTextColor              rowView getResources   getColor R color my title color                         You can use too   private static final int bgColor   0xAAAAFFFF  public View getView int position  View convertView  ViewGroup parent                         View rowView   inflater inflate this rowLayoutID  parent  false               rowView setBackgroundColor bgColor

use them in Java code like this    color   getResources   getColor R color mycolor     The getResources   method returns the ResourceManager class for the current activity  and getColor   asks the manager to look up a color given a resource ID

Even better  you do not need to create separate android xml layout for list cell view  You can just use  android R layout simple list item 1  if the list only contains textview   private class ExampleAdapter extends ArrayAdapter lt String gt        public ExampleAdapter Context context  int textViewResourceId  String   objects            super context  textViewResourceId  objects               Override     public View getView int position  View convertView  ViewGroup parent              View view    super getView position  convertView  parent            TextView tv    TextView  view findViewById android R id text1           tv setTextColor 0            return view

You need to create a CustomListAdapter    public class CustomListAdapter extends ArrayAdapter  lt String gt         private Context mContext      private int id      private List  lt String gt items        public CustomListAdapter Context context  int textViewResourceId   List lt String gt  list                  super context  textViewResourceId  list                      mContext   context          id   textViewResourceId          items   list               Override     public View getView int position  View v  ViewGroup parent                View mView   v           if mView    null               LayoutInflater vi    LayoutInflater mContext getSystemService Context LAYOUT INFLATER SERVICE               mView   vi inflate id  null                      TextView text    TextView  mView findViewById R id textView            if items get position     null                         text setTextColor Color WHITE               text setText items get position                text setBackgroundColor Color RED                int color   Color argb  200  255  64  64                    text setBackgroundColor  color                        return mView             The list item looks like this  custom list xml      lt  xml version  1 0  encoding  utf-8   gt   lt LinearLayout   xmlns android  http   schemas android com apk res android    android layout width  wrap content    android layout height  wrap content  gt   lt TextView       android layout width  fill parent       android layout height  wrap content       android id    id textView      android textSize  20px  android paddingTop  10dip  android paddingBottom  10dip   gt   lt  LinearLayout gt    Use the TextView api s to decorate your text to your liking  and you will be using it like this   listAdapter   new CustomListAdapter YourActivity this   R layout custom list   mList   mListView setAdapter listAdapter

Create a CustomAdapter and in that you have the getView   so there if you want to change the listview background color use this     v setBackgroundColor Color CYAN     If you want to change the textColor then do this    tv setTextColor Color RED     and for the textSize     tv setTextSize 20     where  v  is the listview and  tv  is the textview
