toplayout.xml

   <linearlayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/linear1"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal"     >       <button         android:id="@+id/butt1"         android:layout_width="130dp"         android:layout_height="wrap_content"         android:layout_marginleft="24dp"         android:layout_marginstart="20dp"         android:layout_margintop="24dp"         android:background="@drawable/mybutton"          android:text="@string/schedule" />  </linearlayout> 

mainactivity.java

 private  linearlayout lin1;    private button bt1;    protected void oncreate(bundle savedinstancestate) {       // todo auto-generated method stub     super.oncreate(savedinstancestate);     setcontentview(r.layout.usemerge);       final layoutinflater  inflater =            (layoutinflater)getsystemservice(context.layout_inflater_service);       lin1 = (linearlayout)findviewbyid(r.id.i1);         view vi=inflater.inflate(r.layout.toplayout,lin1,false);          lin1.addview(vi);         bt1=(button)vi.findviewbyid(r.id.butt1);          bt1.setonclicklistener(new view.onclicklistener() {              @override             public void onclick(view vo) {                 // todo auto-generated method stub                  intent ain=new intent(getbasecontext(), scheduleactivity.class);                 startactivity(ain);              }         }); 

define activity in androidmanifest.xml :

<activity android:name=".scheduleactivity"/>  

set click listener before add button linearlayout :

public class mainactivity extends fragmentactivity {      private linearlayout lin1;     private button bt1;      protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.usemerge);          lin1 = (linearlayout) findviewbyid(r.id.i1);         view vi = layoutinflater.from(this).inflate(r.layout.toplayout, lin1, false);         bt1 = (button) vi.findviewbyid(r.id.butt1);         bt1.setonclicklistener(new view.onclicklistener() {              @override             public void onclick(view vo) {                 intent ain = new intent(mainactivity.this, scheduleactivity.class);                 startactivity(ain);             }         });         lin1.addview(vi);     }  }
