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)); 
 
  } 
}
