Answer 1

Check this one,

TextView textView = (TextView) findViewById(R.id.text1);
textView.setText("Welcome");
textView.setTextColor(Color.WHITE);
textView.setBackgroundColor(Color.RED);

Answer 2

This may be Help You.

textview.setBackgroundResource(R.color.white);

Note :instead of textview you need to write your TextView object name.
