Android之ImageSwitcher的实例详解

public class AndroidUIActivity extends Activity {    // 当前显示的图片索引   private int index;    // 图片数组   private int[] images = { R.drawable.image1, R.drawable.image2,       R.drawable.image3, R.drawable.image4, R.drawable.image5 };    /** Called when the activity is first created. */   @Override   public void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      // 全屏设置     requestWindowFeature(Window.FEATURE_NO_TITLE);     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,         WindowManager.LayoutParams.FLAG_FULLSCREEN);      setContentView(R.layout.main);      // 得到ImageSwitcher对象     final ImageSwitcher is = (ImageSwitcher) findViewById(R.id.imageSwitcher1);      // 实现并设置工厂内部接口的makeView方法，用来显示视图。     is.setFactory(new ViewFactory() {        public View makeView() {         return new ImageView(AndroidUIActivity.this);       }     });      // 设置图片来源     is.setImageResource(images[index]);      // 设置点击监听器     is.setOnClickListener(new View.OnClickListener() {        public void onClick(View v) {         // 点击会切换图片         index++;         if (index >= images.length) {           index = 0;         }         is.setImageResource(images[index]);       }     });      // 设置切入动画     is.setInAnimation(AnimationUtils.loadAnimation(getApplicationContext(),         android.R.anim.slide_in_left));     // 设置切出动画     is.setOutAnimation(AnimationUtils.loadAnimation(         getApplicationContext(), android.R.anim.slide_out_right));    } }
