圆盘菜单

来源：互联网发布：unity3d 水的特效编辑：程序博客网时间：2024/05/16 19:27

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好.

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

[java]
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <RelativeLayout
        android:layout_width="100dip"
        android:layout_height="50dip"

        <ImageButton

            android:layout_centerInParent="true"
            android:background="@drawable/icon_home" />
    </RelativeLayout>

    <RelativeLayout

2. MainActivity;

[java]
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;
import android.widget.RelativeLayout;

public class MainActivity extends Activity {

    private ImageButton home;
    private ImageButton menu;
    private RelativeLayout level2;
    private RelativeLayout level3;

    private boolean isLevel2Show = true;
    private boolean isLevel3Show = true;

    @Override
    public void onCreate(Bundle savedInstanceState) {

                        //隐藏2级导航菜单
                        MyAnimation.startAnimationOUT(level2, 500, 500);
                        isLevel3Show = !isLevel3Show;
                    }

    }

}

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;

import android.widget.ImageButton;
import android.widget.RelativeLayout;

public class MainActivity extends Activity {

     }
    }
    isLevel2Show = !isLevel2Show;
   }
  });

}

3. 自定义动画类MyAnimation:

[java]
import android.view.View;
import android.view.ViewGroup;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.RotateAnimation;

public class MyAnimation {
    //入动画
    public static void startAnimationIN(ViewGroup viewGroup, int duration){
        for(int i = 0; i < viewGroup.getChildCount(); i++ ){
            viewGroup.getChildAt(i).setVisibility(View.VISIBLE);//设置显示
            viewGroup.getChildAt(i).setFocusable(true);//获得焦点
            viewGroup.getChildAt(i).setClickable(true);//可以点击
        }

        Animation animation;
        /**
         * 旋转动画
         * RotateAnimation(fromDegrees, toDegrees, pivotXType, pivotXValue, pivotYType, pivotYValue)
         * fromDegrees 开始旋转角度
         * toDegrees 旋转到的角度
         * pivotXType X轴参照物
         * pivotXValue x轴旋转的参考点
         * pivotYType Y轴参照物
         * pivotYValue Y轴旋转的参考点
         */
        animation = new RotateAnimation(-180, 0, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 1.0f);
        animation.setFillAfter(true);//停留在动画结束位置
        animation.setDuration(duration);

        viewGroup.startAnimation(animation);

    }

    //出动画
    public static void startAnimationOUT(final ViewGroup viewGroup, int duration , int startOffSet){
        Animation animation;
        animation = new RotateAnimation(0, -180, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 1.0f);
        animation.setFillAfter(true);//停留在动画结束位置
        animation.setDuration(duration);
        animation.setStartOffset(startOffSet);
        animation.setAnimationListener(new AnimationListener() {

            @Override
            public void onAnimationStart(Animation animation) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onAnimationRepeat(Animation animation) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                for(int i = 0; i < viewGroup.getChildCount(); i++ ){
                    viewGroup.getChildAt(i).setVisibility(View.GONE);//设置显示
                    viewGroup.getChildAt(i).setFocusable(false);//获得焦点
                    viewGroup.getChildAt(i).setClickable(false);//可以点击
                }

            }
        });

        viewGroup.startAnimation(animation);
    }
}

import android.view.View;
import android.view.ViewGroup;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.RotateAnimation;

public class MyAnimation {
//入动画
public static void startAnimationIN(ViewGroup viewGroup, int duration){
  for(int i = 0; i < viewGroup.getChildCount(); i++ ){
   viewGroup.getChildAt(i).setVisibility(View.VISIBLE);//设置显示
   viewGroup.getChildAt(i).setFocusable(true);//获得焦点
   viewGroup.getChildAt(i).setClickable(true);//可以点击
  }

  Animation animation;
  /**
   * 旋转动画
   * RotateAnimation(fromDegrees, toDegrees, pivotXType, pivotXValue, pivotYType, pivotYValue)
   * fromDegrees 开始旋转角度
   * toDegrees 旋转到的角度
   * pivotXType X轴参照物
   * pivotXValue x轴旋转的参考点
   * pivotYType Y轴参照物
   * pivotYValue Y轴旋转的参考点
   */
  animation = new RotateAnimation(-180, 0, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 1.0f);
  animation.setFillAfter(true);//停留在动画结束位置
  animation.setDuration(duration);

  viewGroup.startAnimation(animation);

}

//出动画
public static void startAnimationOUT(final ViewGroup viewGroup, int duration , int startOffSet){
  Animation animation;
  animation = new RotateAnimation(0, -180, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 1.0f);
  animation.setFillAfter(true);//停留在动画结束位置
  animation.setDuration(duration);
  animation.setStartOffset(startOffSet);
  animation.setAnimationListener(new AnimationListener() {

   @Override
   public void onAnimationStart(Animation animation) {
    // TODO Auto-generated method stub

   }

   @Override
   public void onAnimationRepeat(Animation animation) {
    // TODO Auto-generated method stub

   }

   @Override
   public void onAnimationEnd(Animation animation) {
    for(int i = 0; i < viewGroup.getChildCount(); i++ ){
     viewGroup.getChildAt(i).setVisibility(View.GONE);//设置显示
     viewGroup.getChildAt(i).setFocusable(false);//获得焦点
     viewGroup.getChildAt(i).setClickable(false);//可以点击
    }

   }
  });

  viewGroup.startAnimation(animation);
}
}

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.
