Package gphone. ex03_03; import android. app. activity; import android. content. res. resources; import android. OS. bundle; import android. widget. textview; public class ex03_03 extends activity {/** called when the activity is first created. * // @ override public void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); setcontentview (R. layout. main );Resources resources = This. getbasecontext (). getresources (); int color = resources. getcolor (R. color. red); textview TV = (textview) This. findviewbyid (R. id. text); TV. setbackgroundcolor (color );}}
 

Or the color is defined using the System-defined color during encoding:

 Package Gphone. ex03_03; Import Android. App. activity; Import Android. content. res. Resources;Import Android. OS. Bundle; Import Android. widget. textview; Public   Class Ex03_03 Extends Activity { /** Called when the activity is first created .*/ @ Override Public   Void Oncreate (bundle savedinstancestate ){ Super . Oncreate (savedinstancestate); setcontentview (R. layout. Main );/* Resources resources = This. getbasecontext (). getresources (); int color = resources. getcolor (R. color. Red );*/ Textview TV = (textview) This . Findviewbyid (R. Id. Text); TV. setbackgroundcolor ( Android. Graphics. color. Red );}}
