}

here rownumadapter.java

public class rownumadapter extends baseadapter {

private context mcontext; private  int numrows;   public rownumadapter(context context) {      this.mcontext=context;     this.numrows= 5;  } public void addrows() {     this.numrows+=1; } @override public int getcount() {     // todo auto-generated method stub     return this.numrows; }  @override public object getitem(int position) {      return null; }  @override public long getitemid(int position) {      return 0; }  @override public view getview(int position, view convertview, viewgroup parent) {       button view = null;     if(convertview == null)     {            view = new button(this.mcontext);     }     else     {         view = (button)convertview;     }      view.settext(" row " + position);       return view; } 

}

here activity_main.xml :

<?xml version="1.0" encoding="utf-8"?>  <linearlayout  xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingleft="10dp" android:paddingright="15dp">  <button android:layout_margintop="15dp" android:layout_height="wrap_content" android:layout_width="fill_parent" android:text="add view" android:id="@+id/button"></button>  <listview android:id="@+id/listview" android:layout_width="match_parent" android:layout_height="wrap_content" android:focusable="false" android:clickable="false"  >  </listview>   </linearlayout> 

you have use getview method adapter class. ref.

it should this.

@override public view getview(final int position, view convertview, viewgroup parent) {     layoutinflater inflater = (layoutinflater) thiscontext             .getsystemservice(context.layout_inflater_service);     view vi = convertview;      // layout here     vi = inflater.inflate(r.layout.activity_main, null);      // set button id here      button btncheckin = (button) vi.findviewbyid(r.id.btncheckin);          btncheckin.setonclicklistener(new onclicklistener() {             @override             public void onclick(view v) {                      log.d("you clicked", "the item @ [" + position                             + "] position");                    // button action here.              }         });     }       return vi; }
