Setting the rerources like color using resource file does not work in non activity class.

We need to access the resource folder and then we can set the color.

Eg:
 
   TextView tv = (TextView)findViewById(R.id.text1);
 
Incorrect: 
      tv.setTextColor(R.color.color_name);
 
Correct Syntex:
   tv.setTextColor(getResources().getColor(R.colo.color_name));
