一. 简单示例

src

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));

	}
}
