Question

在我的项目中，我在RelativeLayout上有了Right to Left动画，完成之后，在同一个位置，我需要Popupdropdown.Both动画＆amp;下拉工作不错但不是一个接一个。请指导我该怎么做。谢谢你。

scroll_bar_animation.setAnimation(animation_right_left);
scroll_bar_animation.startAnimation(animation_right_left);
location = new int[2];
scroll_bar_animation.getLocationOnScreen(location);
p = new Point();
p.x = location[0];
p.y = location[1];
final View v = upper_scrollbar;

new Handler().postDelayed(new Runnable() {
public void run() {
low_scrollbar.setVisibility(View.GONE);//This is to be disappear after animation so
more_Info_Popup.showPopup(p, v, p.x);//This is the popup window and implemented in
an other class
}
}, 400L);

将AnimationListener添加到您的scroll_bar_animation实例，并在此方法中显示弹出窗口结束时：

  public void onAnimationEnd(Animation animation)
  {...}

首先我们要创建动画类的实例

Animation animation_right_left = AnimationUtils.loadAnimation(this,R.anim.reverse_left);
animation_right_left.setAnimationListener(new AnimationListener() {
.....implement the unimplemented methods  }

动画完成后弹出窗口显示
