Question

我有抽屉类，那个节目，抽屉布局和我用于所有活动并且有一个抽屉xml，其中包含drawerLayout＆amp; NavigationDrawer。

通过拖动它可以正常工作但我想从右边打开抽屉，点击toggleButton。当我点击toggleButton并尝试从右侧打开导航抽屉时。

异常：java.lang.IllegalArgumentException：找不到重力RIGHT的抽屉视图：

drawerLayout.closeDrawer（Gravity.RIGHT）;

我在drawerLayout中使用（tools：openDrawer =“right”）。

我想要一直打开抽屉（rtl和ltr语言）

drawer.xml：
