android 幻灯片效果之平移

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：

a，左边向右边平移

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 yanglonghui * */public class TranslateLeft implements ITurnPage {	private int duration=500;//动画持续时间	private PaintFlagsDrawFilter pdf=new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG);		public TranslateLeft() {		// 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[1].getWidth())/2;		int dy=(maxHeight-bitmap[1].getHeight())/2;				int dx2=(maxWidth-bitmap[0].getWidth())/2;		int dy2=(maxHeight-bitmap[0].getHeight())/2;				long start=System.currentTimeMillis();		long runMills=0;				Rect src=new Rect();		Canvas canvas=null;		boolean isRunning=true;		while(isRunning)		{			isRunning=((runMills=(System.currentTimeMillis()-start))
b，右边向左边平移
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 yanglonghui * */public class TranslateRight implements ITurnPage {	private int duration=500;//动画持续时间	private PaintFlagsDrawFilter pdf=new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG);		public TranslateRight() {		// 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 dx2=(maxWidth-bitmap[1].getWidth())/2;		int dy2=(maxHeight-bitmap[1].getHeight())/2;				long start=System.currentTimeMillis();		long runMills=0;				Rect src=new Rect();		Canvas canvas=null;		boolean isRunning=true;		while(isRunning)		{			isRunning=((runMills=(System.currentTimeMillis()-start))
