如何禁用viewpager当导航抽屉被打开 [英] How to disable viewpager when navigation drawer is open

问题描述

我写了一个简单的code导航抽屉，3个固定的标签，但我面对这些两个错误
1>即使在导航抽屉是打开的，当我点击它......这是在同一地点藏在抽屉式导航栏后面present的标签获得点击为好。
2>当我点击导航抽屉里的物品......得到执行的行动，但片段没有被替换viewpager或更多precisely隐藏的。

I have written a simple code with navigation drawer and 3 fixed tabs but i facing these two bugs 1> Even when the navigation drawer is open and when i click on it... The tabs which are present at the same spot hidden behind the navigation drawer get clicked as well. 2> When i click the items on navigation drawer... the action get performed but the fragment is not replaced or more precisely hidden by the viewpager.

下面是codeS ..
MainActivity.java

Here are the codes.. MainActivity.java

推荐答案

在你的 fragment_navigation_drawer.xml ：

集rootview 点击 =真。

set rootview clickable = true.
