// class that defines events on clicking menu button
class NaviClickListener implements OnClickListener {
    @Override

        MainFrame me = MainFrame.this;
        Context context = me;
        Animation anim;

        int w = parentLinearLayout.getMeasuredWidth();
        int h = parentLinearLayout.getMeasuredHeight();
        int left = (int) (parentLinearLayout.getMeasuredWidth() * 0.55);

     first than remove this property)
        anim.setFillAfter(false);


        // Only use fillEnabled and fillAfter if we don't call layout ourselves.
        // We need to do the layout ourselves and not use fillEnabled and fillAfter 
  because when the anim is finished
        // although the View appears to have moved, it is actually just a drawing effect and the View hasn't moved.
        // Therefore clicking on the screen where the button appears does not work, but clicking where the View *was* does
        // work.
        // anim.setFillEnabled(true);
        // anim.setFillAfter(true);

        parentLinearLayout.startAnimation(anim);

//////////////////////////////// 嗨，我在制作菜单栏时遇到问题。

它的工作方式与Facebook菜单栏类似 -

（当我按下按钮时，会出现包含可扩展列表视图和主布局移动的菜单到页面的右侧）。

问题是，当我点击列表视图以展开父行（以查看子行）时，

菜单消失，主要布局返回主页。

当我通过使用expandGroup（）方法

强制扩展父行时，我试图找出它

它再次发生。

我想解决它，但我不能自己解决。请帮助我〜（为我糟糕的英语而烦恼）

- ＆GT;我是使用AnimationListener制作的。

制作菜单栏时出现ExpandableListView问题（与facebook类似）
