Android 高仿【优酷】圆盘旋转菜单的实现(转载)

来源:互联网 发布:苹果手机加速软件 编辑:程序博客网 时间:2024/05/07 03:46

目前,用户对安卓应用程序的UI设计要求越来越高,因此,掌握一些新颖的设计很有必要.

比如菜单,传统的菜单已经不能满足用户的需求. 其中优酷中圆盘旋转菜单的实现就比较优秀,这里我提供下我的思路及实现,仅供参考.


不过在这里个人认为点击home图标关闭菜单的时候先关第三层,接着第二层,效果比较好看点,只需在关闭第二层的时候加个延迟便可。


该菜单共分里外三层导航菜单.可以依次从外向里关闭三层菜单,也可以反向打开,并且伴有圆盘旋转的动画效果

首先,看下效果:



以下是具体的代码及解释:

1. 菜单布局文件:

大家看到主要有三个RalativeLayout,就是大家看到的三层,但是关于图片的倾斜 是怎样实现的呢?实际上是个假象,图片是正放的,里面图像是倾斜的

2. MainActivity:

3. 自定义动画类MyAnimation:

  3. import android.view.animation.Animation;      
  4. import android.view.animation.Animation.AnimationListener;      
  5. import android.view.animation.RotateAnimation;      
  6.       
  7. public class MyAnimation {      
  8.     //入动画      
  9.     public static void startAnimationIN(ViewGroup viewGroup, int duration){      
  10.         for(int i = 0; i < viewGroup.getChildCount(); i++ ){      
  11.             viewGroup.getChildAt(i).setVisibility(View.VISIBLE);//设置显示      
  12.             viewGroup.getChildAt(i).setFocusable(true);//获得焦点      
  13.             viewGroup.getChildAt(i).setClickable(true);//可以点击      
  14.         }      
  15.               
  16.         Animation animation;      
  17.         /**   
  18.          * 旋转动画

  20.          * fromDegrees 开始旋转角度   
  21.          * toDegrees 旋转到的角度   
  22.          * pivotXType X轴 参照物   
  23.          * pivotXValue x轴 旋转的参考点   
  24.          * pivotYType Y轴 参照物   
  25.          * pivotYValue Y轴 旋转的参考点   
  26.          */      
  27.         animation = new RotateAnimation(-1800, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 1.0f);      
  28.         animation.setFillAfter(true);//停留在动画结束位置      
  29.         animation.setDuration(duration);      
  30.               
  31.         viewGroup.startAnimation(animation);      
  32.               
  33.     }      
  34.           
  35.     //出动画      
  36.     public static void startAnimationOUT(final ViewGroup viewGroup, int duration , int startOffSet){      
  37.         Animation animation;      
  38.         animation = new RotateAnimation(0, -180, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 1.0f);      
  39.         animation.setFillAfter(true);//停留在动画结束位置      
  40.         animation.setDuration(duration);      
  41.         animation.setStartOffset(startOffSet);      
  42.         animation.setAnimationListener(new AnimationListener() {      
  43.                   
  44.             @Override      
  45.             public void onAnimationStart(Animation animation) {      
  46.                 // TODO Auto-generated method stub      
  47.                       
  48.             }      
  49.                   
  50.             @Override      
  51.             public void onAnimationRepeat(Animation animation) {      
  52.                 // TODO Auto-generated method stub      
  53.                       
  54.             }      
  55.                   
  56.             @Override      
  57.             public void onAnimationEnd(Animation animation) {      
  58.                 for(int i = 0; i < viewGroup.getChildCount(); i++ ){      
  59.                     viewGroup.getChildAt(i).setVisibility(View.GONE);//设置显示      
  60.                     viewGroup.getChildAt(i).setFocusable(false);//获得焦点      
  61.                     viewGroup.getChildAt(i).setClickable(false);//可以点击      
  62.                 }      
  63.                       
  64.             }      
  65.         });      
  66.               
  67.         viewGroup.startAnimation(animation);      
  68.     }      
  69. }      

这样,一个高仿优酷三级导航圆盘旋转菜单就完成了.,以后完全可以借鉴这些优秀的UI设计,甚至根据新的需求,可以做出更好的UI.
