Android: set color programatically from XML color constants

Color entries should be like this

<color name="tableHead">#FF444444</color>

and use tv.setBackgroundResource(R.color.tableHead);

Use,..

Color.parseColor("#bdbdbd");

like,

mTextView.setTextColor(Color.parseColor("#bdbdbd"));

OR......................

Get a handle to the root layout used, then set the background color on that. The root layout is whatever you called setContentView with.

// Now get a handle to any View contained // within the main layout you are using

 View someView = findViewById(R.id.randomViewInMainLayout);

// Find the root view

 View root = someView.getRootView()

// Set the color

  root.setBackgroundColor(getResources().getColor(android.R.color.red));

tv.setTextColor(getResources().getColor(R.color.tableHead));

And guess what your colors.xml should be like this

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="tableHead">#FF444444</color>
</resources>
