Java code:

Inflateractivity, Java

Package Fover. inflater; import android. app. activity; import android. content. intent; import android. OS. bundle; import android. view. view; import android. view. view. onclicklistener; import android. widget. button; public class inflateractivity extends activity implements onclicklistener {private button button1; private button button2;/** called when the activity is first created. * // @ overridepublic void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); setcontentview (R. layout. main); findview (); setonclick () ;}/ *** Description: Set the listener event */private void setonclick () {button1.setonclicklistener (this); button2.setonclicklistener (this );} /*** Description: Various views */private void findview () {button1 = (button) findviewbyid (R. id. button1); button2 = (button) findviewbyid (R. id. button2) ;}@ overridepublic void onclick (view v) {Switch (v.

Personal. Java

 
Package Fover. inflater; import android. app. activity; import android. OS. bundle; import android. view. layoutinflater; import android. view. view; import android. view. viewgroup. layoutparams; import android. view. window; import android. widget. linearlayout; public class personal extends activity {private view inflaterview; private linearlayout bgview; @ overrideprotected void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); requestwindowfeature (window. feature_no_title); setcontentview (R. layout. background); bgview = (linearlayout) findviewbyid (R. id. bglayout); layoutinflater Inflater = layoutinflater. from (this); inflaterview = Inflater. inflate (R. layout. inflater, null); bgview. addview (inflaterview, new layoutparams (layoutparams. match_parent, layoutparams. match_parent ));}}
 

Rank. Java

Package Fover. inflater; import android. app. activity; import android. OS. bundle; import android. view. layoutinflater; import android. view. view; import android. view. viewgroup. layoutparams; import android. view. window; import android. widget. linearlayout; public class rank extends activity {private linearlayout bigview; private view inflaterview; @ overrideprotected void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); requestwindowfeature (window. feature_no_title); setcontentview (R. layout. background); bigview = (linearlayout) findviewbyid (R. id. bglayout); layoutinflater Inflater = layoutinflater. from (this); inflaterview = Inflater. inflate (R. layout. inflater2, null); bigview. addview (inflaterview, new layoutparams (layoutparams. match_parent, layoutparams. match_parent ));}}
