动画效果介绍：

1.点击Actionbar上“+”按钮，菜单从上方d出（带反d效果）；
2.再次点击“+”、点击空白区域或者点击返回键，菜单向上方收起；
3.点击d出框上的按钮时，该按钮放大，其它按钮缩小，菜单整体渐变退出。

主体代码：

1.Activity.

/** * 仿易信动画d出框 */public class MainActivity extends ActionBaractivity {  //用于标记页面顶端位置  private VIEw topVIEw;  @OverrIDe  protected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.activity_main);    topVIEw = findVIEwByID(R.ID.main_top);  }  private PopupWindow popupWindow;  private int line1DeltaY,line2DeltaY;  //仿易信更多d出框  private voID showPopup() {    if (popupWindow == null) {      VIEw contentVIEw = LayoutInflater.from(this).inflate(R.layout.yixin_pop_layout,null);

     itemVIEws[i] = parent.findVIEwByID(ID);      GrIDLayout.LayoutParams p = (GrIDLayout.LayoutParams) itemVIEws[i].getLayoutParams();      p.wIDth = itemWIDth;      itemVIEws[i].setLayoutParams(p);      itemVIEws[i].setonClickListener(l);    }  }  private class OnClickImpl implements VIEw.OnClickListener {    @OverrIDe    public voID onClick(VIEw v) {      final int vIEwID = v.getID();      //背景动画      popupWindow.getContentVIEw().startAnimation(AnimationHelper.createPopupBgFadeOutAnim(AnimationHelper.TIME_OUT_CliCK));

2.动画工具类。

/** * AnimationHelper */public class AnimationHelper {  /**   * 进入动画的时间   */  public static final int TIME_IN = 300;  /**   * 进入动画之后的反d动画时间   */  public static final int TIME_IN_BACK = 100;  /**   * 退出动画的时间   */  public static final int TIME_OUT = 300;  /**   * 点击PopupWindow上菜单后退出动画的时间   */  public static final int TIME_OUT_CliCK = 500;  /**   * PopupWindow上菜单进入动画   */  public static Animation createPopupAnimIn(Context context,int fromYDelta) {    AnimationSet animationSet = new AnimationSet(context,null);//    animationSet.setInterpolator(new BounceInterpolator()); //结束时d跳    animationSet.setFillAfter(true);    //移动    TranslateAnimation translateAnim = new TranslateAnimation(0,fromYDelta,20);    translateAnim.setDuration(TIME_IN);    animationSet.addAnimation(translateAnim);    //回d效果    TranslateAnimation translateAnim2 = new TranslateAnimation(0,-20);    translateAnim2.setStartOffset(TIME_IN);    translateAnim2.setDuration(TIME_IN_BACK);    animationSet.addAnimation(translateAnim2);    return animationSet;  }  /**   * PopupWindow上菜单离开动画   */  public static Animation createPopupAnimOut(Context context,int toYDelta) {    AnimationSet animationSet = new AnimationSet(context,null);    animationSet.setFillAfter(true);    TranslateAnimation translateAnim = new TranslateAnimation(0,toYDelta);    translateAnim.setDuration(TIME_OUT);    animationSet.addAnimation(translateAnim);    return animationSet;  }  /**   * PopupWindow背景进入动画（透明度渐变）   */  public static Animation createPopupBgFadeInAnim() {    AlphaAnimation anim = new AlphaAnimation(0,1.0f);    anim.setDuration(TIME_IN);    anim.setFillAfter(true);    return anim;  }  /**   * PopupWindow背景离开动画（透明度渐变）   */  public static Animation createPopupBgFadeOutAnim(int duration) {    AlphaAnimation anim = new AlphaAnimation(1.0f,0);    anim.setDuration(duration);    anim.setFillAfter(true);    return anim;  }  /**   * PopupWindow按钮点击动画   */  public static Animation createPopupItemBiggerAnim(Context context) {    AnimationSet animationSet = new AnimationSet(context,null);    animationSet.setFillAfter(true);    //放大(设置缩放的中心点为自己的中心)    ScaleAnimation scaleAnim = new ScaleAnimation(1.0f,2.0f,1.0f,Animation.relative_TO_SELF,0.5f,0.5f);    scaleAnim.setDuration(TIME_OUT_CliCK);    animationSet.addAnimation(scaleAnim);    //渐变    AlphaAnimation AlphaAnim = new AlphaAnimation(1.0f,0);    AlphaAnim.setInterpolator(new AccelerateInterpolator());    AlphaAnim.setDuration(TIME_OUT_CliCK);    animationSet.addAnimation(AlphaAnim);    return animationSet;  }  /**   * PopupWindow按钮点击时其它按钮的动画   */  public static Animation createPopupItemSmallerAnim(Context context) {    //放大(设置缩放的中心点为自己的中心)    ScaleAnimation scaleAnim = new ScaleAnimation(1.0f,0.5f);    scaleAnim.setDuration(TIME_OUT_CliCK);    scaleAnim.setFillAfter(true);    return scaleAnim;  }}
