Question

我想在Android中创建一个Reveal菜单，就像Jquery mobile一样。我希望主FrameLayout向左滑动30％，然后显示其后面的另一个布局，即菜单布局。

滑动FrameLayout的编码成功;那是当我点击菜单时，它左侧30％的距离。我遇到的问题是，当它向左滑动时，菜单按钮在其当前位置停止响应，但它在其初始位置响应，而菜单按钮已向下移动了framelayout 30％

这是我的代码

activity_main.xml中

再次单击菜单按钮，它再次调用移动方法，但它不能再移动30％，所以看起来没有移动使用下面的代码。

>>> a=u'-100'

>>> int(a)
-100

>>> float(a)
-100.0

创建显示菜单
