上周我开始开发android。我正在为我训练的健身房制作应用程序。到目前为止,我已经完成了主要功能,但是当打开或关闭导航抽屉时,我仍然试图添加动画。现在,导航抽屉功能齐全,但箭头没有动画,如图所示:
这是使用Android Studio制作的项目的链接: App
这是主要活动。该应用程序的Java:

您需要同步抽屉:
ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(<context>, drawerLayout, 0, 0, 0);
drawerLayout.setDrawerListener(drawerToggle);
drawerToggle.syncState();
