package abc.xys;  import android.annotation.suppresslint; import android.app.activity; import android.os.bundle; import android.os.handler; import android.os.message; import android.widget.imageview; import android.widget.textview;  public class wishes extends activity {      imageview slide;     textview msg;      int i=0;     int imgid[]={r.drawable.friends01,r.drawable.friends02,r.drawable.friends03,r.drawable.friends04,r.drawable.friends05};      refreshhandler refreshhandler=new refreshhandler();      @suppresslint("handlerleak")     class refreshhandler extends handler{         @override         public void handlemessage(message msg) {             // todo auto-generated method stub             wishes.this.updateui();         }         public void sleep(long delaymillis){             this.removemessages(0);             sendmessagedelayed(obtainmessage(0), delaymillis);         }     };     public void updateui(){         int currentint=integer.parseint((string)msg.gettext())+10;         if(currentint<=100){             refreshhandler.sleep(2000);             msg.settext(string.valueof(currentint));             if(i<imgid.length){                 slide.setimageresource(imgid[i]);                  // slide.setpadding(left, top, right, bottom);                 i++;             }         }     }         @override     protected void oncreate(bundle savedinstancestate) {         // todo auto-generated method stub         super.oncreate(savedinstancestate);         setcontentview(r.layout.wishes_template);         slide = (imageview) findviewbyid(r.id.slideshow);         msg = (textview) findviewbyid(r.id.message);      }  } 

the xml file (wishes_template) is:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"   android:layout_height="match_parent"   android:orientation="vertical"   android:id="@+id/slideshow_layout"   >       <imageview android:id="@+id/slideshow"               android:layout_width="wrap_content"               android:layout_height="wrap_content"               android:layout_gravity="center"               android:paddingtop="20dp"               ></imageview>      <textview android:text="10"                android:id="@+id/message"                android:layout_width="fill_parent"                android:layout_height="wrap_content"></textview> </linearlayout>
