从另一个活动返回时，SearchView会获得焦点并打开键盘 [英] SearchView gains focus and opens keyboard when returning from another activity

问题描述

当我从另一个活动返回到主要活动时，searchView获得了焦点，并且键盘打开了，我设法使用以下命令阻止了键盘的打开:

When I return from another activity to the main activity, the searchView gains focus and the keyboard opens, I managed to stop the keyboard from opening by using:

    getWindow().setSoftInputMode(
              WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

但这还不够，如果打开并关闭了操作栏下拉菜单，则键盘会再次出现，因为searchView仍然具有焦点(请记住我只关闭了键盘).我试图获取对searchView的引用，并使它失去焦点，但这没有用.

but this is not sufficient, if the actionbar drop down menu is opened and closed the keyboard reappears, because the searchView still has focus (remember I only closed the keyboard). I have tried to get a reference to the searchView and make it lose focus, but this has not worked.

因此，基本上，我只希望searchView永远不要聚焦或提示键盘打开，除非真正触摸了searchView文本区域.

So basically, I just want the searchView to never have focus or prompt the keyboard to open, unless the searchView text area is actually touched.

推荐答案

这是由于SearchView是将活动重新带回视图时的第一个可聚焦视图-相同的问题

This is due to the SearchView being the first focusable view when the activity is brought back into view - the same issue can be seen for EditTexts.

解决方案相同-将层次结构中的较早视图设置为可聚焦.就我而言，这是Toolbar我的SearchView位于以下位置:

The solution is the same - set an earlier view in the hierarchy to focusable. In my case, this was the Toolbar my SearchView was on top of:

<android.support.v7.widget.Toolbar
    style="@style/ToolbarStyle"
    android:focusableInTouchMode="true"
    android:id="@+id/search_activity_toolbar"
    android:layout_height="?attr/actionBarSize"
    android:layout_width="match_parent"/>

<android.support.v7.widget.SearchView
    android:iconifiedByDefault="false"
    ... />

现在，当我进入活动(clearFocus(); requestFocus(...);)时，我可以专注于我的SearchView，然后当您通过搜索结果退出活动，然后通过按Back返回时，键盘处于与您输入时相同的状态左.

Now I can gain focus on my SearchView when entering the activity (clearFocus(); requestFocus(...);), then when you exit the activity via a search result, then return by pressing Back, the keyboard is in the same state as when you left.

请注意，有关链接问题的其他一些解决方案，即在活动"上设置windowSoftInputMode="stateUnchanged" 确实完成了不为我工作.

Note that some of the other solutions on the linked question, namely setting windowSoftInputMode="stateUnchanged" on the Activity did not work for me.
