自动展开并聚焦于 SearchView [英] Expand and give focus to SearchView automatically
问题描述
我正在开发一个应用程序,用户在其中按下 ActionBar
中的搜索"图标,并且 SearchView
在屏幕顶部可见.
I'm developing an application where the user presses the "Search" icon in the ActionBar
and a SearchView
is made visible at the top of the screen.
我的问题是 SearchView
既未聚焦也未展开,因此用户必须按下 Searchview
上的搜索按钮以使其展开并显示键盘.
My problem is that the SearchView
is not in focus nor expanded so the user has to press the search button on the Searchview
to make it expand and bring out the keyboard.
应该如何解决?
推荐答案
要使 SearchView 默认展开,请调用 setIconifiedByDefault(false) 当你初始化它时(例如在 onCreateOptionsMenu(..)
或 onPrepareOptionsMenu(..)
>).我发现在大多数情况下这会自动给它焦点,但如果不是简单地调用 requestFocus()
也可以.
To make the SearchView expanded by default, call setIconifiedByDefault(false) on it when you initialise it (e.g. in onCreateOptionsMenu(..)
or onPrepareOptionsMenu(..)
). I've found in most cases this will give it focus automatically, but if not simply call requestFocus()
on it too.
