Answer 1

searchView.backgroundColorResource = Color.WHITE is the problem. You need to set a resource id here but Color.WHITE is a color value, not a resource id. You can try

searchView.backgroundColorResource = android.R.color.white

Answer 2

You're using a Color value, not a resource reference, so you can't use

searchView.backgroundColorResource = Color.WHITE

As an alternative to Henry's answer, you can use the old Java-style method with

searchView.setBackgroundColor(Color.WHITE)

Answer 3

Use

getApplicationContext().getColor(R.color.white);

And put your color values in xml file, such as

res/values/colors.xml

looking like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="white">#ffffff</color>
    //other colors...
</resources>
