单击工具栏搜索打开导航抽屉

Question

我正在开发一个应用程序，该应用程序具有底部导航菜单、导航抽屉和工具栏中的搜索功能。我现在只有一件事在工作——我遇到的问题是当我点击工具栏中的“搜索图标”时，抽屉也打开了！我真的不明白为什么！我敢肯定这是我看不到的简单事情，但是。 . .

无论如何，有人可以帮忙吗！

Answer 1

在 onOptionsItemSelected 方法中，您定义了当您单击任务栏中的选项时，它应该打开抽屉菜单。尝试删除它。如果您想定义要在任务栏上处理的项目，请在 onOptionsItemSelected 中使用下面的用户代码：

when(item.getId()){

    R.id.item1 -> ////

    R.id.item2 -> ////

}

使用您为菜单项指定的 ID。

Answer 2

问题是您的 onOptionsItemSelected() 没有调用 super.onOptionsItemSelected() - 那个是自动调度对 android.R.id.home 按钮的调用并且是什么连接了 onSupportNavigateUp() 调用。

鉴于 onSupportNavigateUp() 正在为您处理向上按钮，您可以删除整个 onOptionsItemSelected() 实现。
