android 登录3D翻转动画效果
描述：这是一个 登录3D翻转效果的Demo。
项目代码在最后面！！！！跳转到最后
控件效果如下：
实现功能：
- 使页面进行3D翻转（3D翻转效果）
- 可通过回调监听两个页面的显隐
设计核心：
主要的设计核心是依赖于Camera来进行视觉上深度的放大和缩小，而旋转则是依靠动画进行实现。
核心代码：
Rotate3dAnimation.java 一个3D的旋转动画效果，也是旋转动画的核心
import android.graphics.Camera;
import android.graphics.Matrix;
import android.view.animation.Animation;
import android.view.animation.Transformation;
public class Rotate3dAnimation extends Animation
private float mCenterX,mCenterY;
private Camera mCamera;
private RotateListener rotateListener;
private boolean isBack=false;
private boolean ishalf=false;
private float mDegree=180;
public Rotate3dAnimation()
public void setRotateListener(RotateListener rotateListener)
this.rotateListener=rotateListener;
//翻转监听
public void setBack(boolean back)
isBack = back;
//初始化位置
@Override
public void initialize(int width, int height, int parentWidth, int parentHeight)
super.initialize(width, height, parentWidth, parentHeight);
mCamera=new Camera();
mCenterX=(float) width/2;
mCenterY=(float)height/2;
//动画改变
//interpolatedTime 0~1
@Override
protected void applyTransformation(float interpolatedTime, Transformation t)
if (interpolatedTime>0.5&&interpolatedTime<=1)
if (!ishalf)
rotateListener.transhalf(isBack);
ishalf=true;
else if (interpolatedTime<0.5)
if (ishalf)
ishalf=false;
//是否已过一半
float degrees = mDegree * interpolatedTime;
if (isBack)
degrees =180- degrees;
mCamera.save();;
float z;
//Z轴高度500 默认-576
if (interpolatedTime<0.5)
z= 500*interpolatedTime*2;
else
z= 1000 *(1-interpolatedTime);
mCamera.translate(0,0,z);
final Matrix matrix=t.getMatrix();
mCamera.rotateY(degrees);
mCamera.getMatrix(matrix);
mCamera.restore();
matrix.preTranslate(-mCenterX,-mCenterY);
matrix.postTranslate(mCenterX,mCenterY);
super.applyTransformation(interpolatedTime, t);
public interface RotateListener
void transhalf(boolean isback);//移动到一半 适合显隐界面
使用示例：

使用 electron 实现类似新版 QQ 的登录界面效果（阴影背景动画窗体3D翻转）
