public class Galleryactivty extends Activity {private static Gallery mgallery;private int[] images = {R.DRAWABLE.A, R.draw ABLE.B,R.DRAWABLE.C, R.DRAWABLE.D,R.DRAWABLE.E, r.drawable.f,r.drawable.h}; @Overrideprotected void OnCreate (Bundle Savedinstancestate) {//TODO auto-generated method Stubsuper.oncreate (savedinstancestate); Setcontentview ( R.layout.activity_gallery) MGallery = (gallery) Findviewbyid (r.id.gallery); Mgallery.setadapter (new MyAdapter (this) ); mgallery.setspacing (10);} Class Myadapter extends Baseadapter{private context context;public Myadapter (context context) {This.context = context;} @Overridepublic int GetCount () {//Gets the total number of picture resources return images.length;} @Overridepublic Object getItem (int position) {//Get the picture's current position return position;} @Overridepublic long Getitemid (int position) {//Get picture of current position Idreturn images[position];} @Overridepublic view GetView (int position, view Convertview, ViewGroup parent) {//Get current picture resource ImageView View = new ImageView ( This.context); View.setimageresource (Images[position]); View.setadjustviewbounds (true);//Set the size of the picture View.setlayoutparams (new Gallery.layoutparams (300, 300));// View.setpadding (all, ten, ten); return view;}}}
