How to change color of ListView items on focus and on click

Question

i have a list View in my app (this is the xml layout):

Answer 1

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 < 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));
