在上篇文章中实现了优酷菜单执行动画,本文接着完善已经实现的动画功能

已经实现的菜单动画功能存在一点BUG,那就是当快速连续点击menu或home按钮的时候,动画出现进入和退出不定操作现象
下面来解决这一问题,可以通过监听事件来判断当前是否正在执行进入或进出操作,代码如下:
package com.wuyudong.youkumenu.utils; import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.RotateAnimation;
import android.widget.RelativeLayout; public class AnimationUtils { public static int runningAnimationCount = 0; // 旋转出去的动画
public static void rotateOutAnim(RelativeLayout layout, long delay) {
RotateAnimation ra = new RotateAnimation(
0f, -180f, //开始,结束的角度, 逆时针
Animation.RELATIVE_TO_SELF, 0.5f, //相对的x坐标点(指定旋转中心x值)
Animation.RELATIVE_TO_SELF, 1.0f); //相对的y坐标点(指定旋转中心y值)
ra.setDuration(500);
ra.setFillAfter(true); //设置动画停留在结束位置
ra.setStartOffset(delay); //设置动画开始延时
ra.setAnimationListener(new MyAnimationListener());//添加监听
layout.startAnimation(ra); } // 旋转进来的动画
public static void rotateInAnim(RelativeLayout layout) {
RotateAnimation ra = new RotateAnimation(
-180f, 0f, //开始,结束的角度, 顺时针
Animation.RELATIVE_TO_SELF, 0.5f, //相对的x坐标点(指定旋转中心x值)
Animation.RELATIVE_TO_SELF, 1.0f); //相对的y坐标点(指定旋转中心y值)
ra.setDuration(500);
ra.setFillAfter(true);
ra.setAnimationListener(new MyAnimationListener());
layout.startAnimation(ra); } static class MyAnimationListener implements AnimationListener { @Override
public void onAnimationStart(Animation animation) {
runningAnimationCount++; } @Override
public void onAnimationEnd(Animation animation) {
runningAnimationCount--;
} @Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub } } }
在点击事件中添加一小段判断的代码即可
public void onClick(View v) {
if (AnimationUtils.runningAnimationCount > 0) {
//当前有动画正在执行,不执行当前事件
return;
}
.......
问题搞定
接下来还要进一步完善,当用户点击手机menu的时候,同样能得到点击优酷菜单同样的动画效果
这样需要判断用户的点击本机menu按键事件:
public boolean onKeyDown(int keyCode, KeyEvent event) {
// keyCode 事件码
if(keyCode == KeyEvent.KEYCODE_MENU) {
if (AnimationUtils.runningAnimationCount > 0) {
//当前有动画正在执行,不执行当前事件
return true;
}
if (islevel1Display) {
long delay = 0;
//隐藏三级菜单
if(islevel3Display) {
AnimationUtils.rotateOutAnim(rl_level3, 0);
islevel3Display = false;
delay += 200;
} //隐藏二级菜单
if(islevel2Display) {
AnimationUtils.rotateOutAnim(rl_level2, delay);
islevel2Display = false;
delay += 200;
} //隐藏二级菜单
AnimationUtils.rotateOutAnim(rl_level1, delay);
} else {
AnimationUtils.rotateInAnim(rl_level1, 0);
AnimationUtils.rotateInAnim(rl_level2, 200);
AnimationUtils.rotateInAnim(rl_level3, 400); islevel3Display = true;
islevel2Display = true;
}
islevel1Display = !islevel1Display;
return true; //消费当前事件
}
return super.onKeyDown(keyCode, event);
}
完整的AnimationUtils代码如下:
package com.wuyudong.youkumenu.utils; import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.RotateAnimation;
import android.widget.RelativeLayout; public class AnimationUtils { public static int runningAnimationCount = 0; // 旋转出去的动画
public static void rotateOutAnim(RelativeLayout layout, long delay) {
int childCount = layout.getChildCount();
//如果隐藏,则找到所有的子View,禁用
for (int i = 0; i < childCount; i++) {
layout.getChildAt(i).setEnabled(false);
}
RotateAnimation ra = new RotateAnimation(
0f, -180f, //开始,结束的角度, 逆时针
Animation.RELATIVE_TO_SELF, 0.5f, //相对的x坐标点(指定旋转中心x值)
Animation.RELATIVE_TO_SELF, 1.0f); //相对的y坐标点(指定旋转中心y值)
ra.setDuration(500);
ra.setFillAfter(true); //设置动画停留在结束位置
ra.setStartOffset(delay); //设置动画开始延时
ra.setAnimationListener(new MyAnimationListener());//添加监听
layout.startAnimation(ra); } // 旋转进来的动画
public static void rotateInAnim(RelativeLayout layout, long delay) {
int childCount = layout.getChildCount();
//如果隐藏,则找到所有的子View,启用
for (int i = 0; i < childCount; i++) {
layout.getChildAt(i).setEnabled(true);
}
RotateAnimation ra = new RotateAnimation(
-180f, 0f, //开始,结束的角度, 顺时针
Animation.RELATIVE_TO_SELF, 0.5f, //相对的x坐标点(指定旋转中心x值)
Animation.RELATIVE_TO_SELF, 1.0f); //相对的y坐标点(指定旋转中心y值)
ra.setDuration(500);
ra.setFillAfter(true);
ra.setStartOffset(delay); //设置动画开始延时
ra.setAnimationListener(new MyAnimationListener());
layout.startAnimation(ra); } static class MyAnimationListener implements AnimationListener { @Override
public void onAnimationStart(Animation animation) {
runningAnimationCount++; } @Override
public void onAnimationEnd(Animation animation) {
runningAnimationCount--;
} @Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub } } }
