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.
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

3. 自定义动画类MyAnimation:
- 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.
