Android searchview不显示

Question

我到学校制作了一个android应用程序，我想在recyclerview中实现searchview。 我的第一个活动是NavigationDrawer，然后当我使用菜单进行所需的活动时，它打开了很多操作系统的cardview。 主要问题是searchview小部件没有显示，所以我无法使用过滤器

我的布局

更新应用图像

MainActivity

[！[在此处输入图片描述] [1]] [1]

VisitasActivity（应该在其中显示searchview）

[！[在此处输入图片描述] [2]] [2]

使用此代码，我的搜索视图不会显示，并且我无法使用过滤器小部件

有帮助吗？

谢谢

Answer 1

在您的menu.xml中替换

app:showAsAction="ifRoom|collapseActionView"

使用

app:showAsAction="always"

编辑：- 在您的活动中添加main_layout.xml。因为工具栏位于main_layout内部，而不在recyclerVie的xml中。

Answer 2

setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setTitle("Search");

获取工具栏ID并将其传递到setSupportActionBar
