实现原理：

使用SurfaceView一直重绘实现该动画效果

先看效果图：

代码实现：

1.幻灯片基类：

package com.open.turnpage;import android.graphics.Bitmap;import android.view.SurfaceHolder;/** * 幻灯片效果的接口 * @author admin * */public interface ITurnPage {	public abstract void onCreate();		public abstract void onTurnPageDraw(SurfaceHolder holder,Bitmap[] bitmap,int maxWidth,int maxHeight);		public abstract void onDestory();}

a.从左到右实现：

package com.open.turnpage;import android.graphics.Bitmap;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.graphics.PaintFlagsDrawFilter;import android.graphics.Rect;import android.view.SurfaceHolder;/** *  * @author admin * */public class ShutterLeft2Right implements ITurnPage {	private int duration=350;//动画持续时间	private final int leafNum=5;	private PaintFlagsDrawFilter pdf=new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG);		public ShutterLeft2Right() {		// TODO Auto-generated constructor stub	}	@Override	public void onCreate() {		// TODO Auto-generated method stub			}	@Override	public void onTurnPageDraw(SurfaceHolder holder, Bitmap[] bitmap,			int maxWidth, int maxHeight) {				int dx=(maxWidth-bitmap[0].getWidth())/2;		int dy=(maxHeight-bitmap[0].getHeight())/2;		int perWidth=maxWidth/leafNum;				long start=System.currentTimeMillis();		long runMills=0;				Rect src=new Rect();		Rect dst=new Rect();		Canvas canvas=null;		boolean isRunning=true;		while(isRunning)		{			isRunning=((runMills=(System.currentTimeMillis()-start))
b，从右边到左边：package com.open.turnpage;import android.graphics.Bitmap;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.graphics.PaintFlagsDrawFilter;import android.graphics.Rect;import android.view.SurfaceHolder;/** *  * @author admin * */public class ShutterRight2Left implements ITurnPage {	private int duration=350;//动画持续时间	private final int leafNum=5;	private PaintFlagsDrawFilter pdf=new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG);		@Override	public void onCreate() {		// TODO Auto-generated method stub			}	@Override	public void onTurnPageDraw(SurfaceHolder holder, Bitmap[] bitmap,			int maxWidth, int maxHeight) {				int dx=(maxWidth-bitmap[0].getWidth())/2;		int dy=(maxHeight-bitmap[0].getHeight())/2;		int perWidth=maxWidth/leafNum;				long start=System.currentTimeMillis();		long runMills=0;				Rect src=new Rect();		Canvas canvas=null;		boolean isRunning=true;		while(isRunning)		{			isRunning=((runMills=(System.currentTimeMillis()-start))
c，从上到下：
package com.open.turnpage;import android.graphics.Bitmap;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.graphics.PaintFlagsDrawFilter;import android.graphics.Rect;import android.view.SurfaceHolder;/** *  * @author admin * */public class ShutterUp2Down implements ITurnPage {	private int duration=350;//动画持续时间	private final int leafNum=7;	private PaintFlagsDrawFilter pdf=new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG);		public ShutterUp2Down() {		// TODO Auto-generated constructor stub	}	@Override	public void onCreate() {		// TODO Auto-generated method stub	}	@Override	public void onTurnPageDraw(SurfaceHolder holder, Bitmap[] bitmap,			int maxWidth, int maxHeight) {				int dx=(maxWidth-bitmap[0].getWidth())/2;		int dy=(maxHeight-bitmap[0].getHeight())/2;		int perHeight=maxHeight/leafNum;				long start=System.currentTimeMillis();		long runMills=0;				Rect src=new Rect();		Canvas canvas=null;		boolean isRunning=true;		while(isRunning)		{			isRunning=((runMills=(System.currentTimeMillis()-start))
d，从下到上：
package com.open.turnpage;import android.graphics.Bitmap;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.graphics.PaintFlagsDrawFilter;import android.graphics.Rect;import android.view.SurfaceHolder;/** *  * @author admin * */public class ShutterDown2Up implements ITurnPage {	private int duration=350;//动画持续时间	private final int leafNum=7;	private PaintFlagsDrawFilter pdf=new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG);		public ShutterDown2Up() {		// TODO Auto-generated constructor stub	}	@Override	public void onCreate() {		// TODO Auto-generated method stub	}	@Override	public void onTurnPageDraw(SurfaceHolder holder, Bitmap[] bitmap,			int maxWidth, int maxHeight) {				int dx=(maxWidth-bitmap[0].getWidth())/2;		int dy=(maxHeight-bitmap[0].getHeight())/2;		int perHeight=maxHeight/leafNum;				long start=System.currentTimeMillis();		long runMills=0;				Rect src=new Rect();		Canvas canvas=null;		boolean isRunning=true;		while(isRunning)		{			isRunning=((runMills=(System.currentTimeMillis()-start))
