Android的：如何编程一个无焦点搜索查看 [英] Android: How to unfocus a SearchView programmatically

问题描述

我有一个搜索查看我的布局（而不是在操作栏），我无法用通常的方法来取消键盘：

I have a SearchView in my layout (not in the action bar) and I'm unable to dismiss the keyboard using the usual method:

public static void hideKeyboard(Activity activity) {
    InputMethodManager imm = (InputMethodManager)activity
            .getSystemService(Context.INPUT_METHOD_SERVICE);

    if (imm != null && activity != null) {
        View currentFocus = activity.getCurrentFocus();

        if (currentFocus != null) {
            imm.hideSoftInputFromWindow(currentFocus.getWindowToken(), 0);
        }
    }
}

该搜索查看其保持对焦状态。旧设备上使用此方法显示被解雇键盘，然后重新显示。

The SearchView maintains its focus state. Using this method on older devices shows the keyboard being dismissed then redisplaying.

我相信这个问题是一个事实，即搜索查看实际上是在内部保持自己的状态视图的层次结构。

I believe the issue is with the fact that a SearchView is actually a hierarchy of Views that maintain their own state internally.

我怎么不显示键盘并在无焦点搜索查看？

How do I dismiss the keyboard and unfocus the SearchView?

推荐答案

这听起来像什么可能发生的事情是，你unfocusing的搜索查看，然后它说：哦，等等，我还是有重点，我需要的键盘 。是否 activity.getCurrentFocus（）。clearFocus（）清除重点是什么？

It sounds like what might be happening is that you're unfocusing the SearchView and then it's saying "oh wait, I still have focus, I need the keyboard". Does activity.getCurrentFocus().clearFocus() clear out the focus?
