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. */@Overridepublic 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));}}

main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <ImageSwitcher        android:id="@+id/imageSwitcher1"        android:layout_width="wrap_content"        android:layout_height="wrap_content" >    </ImageSwitcher></LinearLayout>
