R.id.content, because all the activity background to change color, therefore must write a base class, the code is as follows:

public class Baseactivity extends Activity {   protected void onCreate (Android.os.Bundle savedinstancestate) {   Super.oncreate (savedinstancestate);   };   @Overridepublic void Setcontentview (int layoutresid) {Super.setcontentview (layoutresid);(((viewgroup) Findviewbyid ( Android. r.id.content). Getchildat (0)). SetBackgroundColor (Getresources (). GetColor (true? R.color.root_view_background_color_night:r.color.root_view_background_color));}}
