public class ButtonpageflipperActivity extends Activity implements OnGestureListener{

// 声明两个按钮,分别代表向左和向右滑动

private ImageView btnLeft = null;

private ImageView btnRight = null;

// 设置WindowManager

private WindowManager wm = null;

private WindowManager.LayoutParams wmParams = null;

// ImageView的alpha值

private int mAlpha = 0;

private boolean isHide;

private ViewFlipper viewFlipper = null;
