Answer 1

There are two main classes for color handling in Java/Android.

This first one is from "plain" Java and can be found in java.awt.Color. This class supports converting a String into a color with the method decode. Example:

Color red = Color.decode("#FF0000");

The second class is for Android and can be found in android.graphics.Color. The conversion can be done with the method parseColor.

int red = Color.parseColor("#FF0000");

So you should check which kind of Color class you've imported to your project. I recommend using the Android version of Color for your case. If you've done that the statement targetView.setBackgroundColor(Color.parseColor("#FFFFFF")); should work.

Define your color in the resource File color.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <color name="yourColor">#FFFFFF</color>
</resources>

and set Backgroundcolor

targetView.setBackgroundResource(R.color.yourColor)
