本文将要模仿Win8界面的一个设计，一个一个的方块。方法很简单。这里自己把图片改改就可以成为自己想要的界面了。
先来看看效果：源码免费下载
1、首先来看看自定义的MyImageView：

}

count--;

count = getDegree();
beginRotate(matrix, (XbigY ? count : 0), (XbigY ? 0 : count));
rotate_Handler.sendEmptyMessage(Rotate_Handler_Message_Turned);
break;
}
}
};
private synchronized void beginRotate(Matrix matrix, float rotateX,
float rotateY) {

}

}
private Handler scale_handler = new Handler() {

}

rotateDegree = degree;
}
public float getScale() {

}
public void setScale(float scale) {

}
}
2、下来，来看看布局
3、上面的图片按钮的用法，这里只给一张图片按钮添加了事件：
MyImageView image_3D_1 = (MyImageView)findViewById(R.id.MyImageView01);
image_3D_1.setOnClickIntent(new MyImageView.OnViewClick() {
@Override
public void onClick() {
Toast.makeText(MainActivity.this, "clicked", 100)
.show();
}
});
4、效果
手指按在中间是缩小，手指按在边上是有角度的卷动
手指一直按着的时候，被按下的那个图像变小，并且手指一直按着移动，此时其它图片按钮不响应
