Question

我创建了一个简单的菜单，其中包含Search View。

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.activity_main_actions, menu);

        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

        return super.onCreateOptionsMenu(menu);
    }

我使用了android:launchMode="singleTop"方法。在我执行搜索和更新UI之后，输入的文本仍然保留在那里。

我想要的是按下搜索按钮后，Search View应将其自身恢复为：

有什么方法可以缩回它吗？

Answer 1

使用@Niti Misra最初建议的内容，我必须在我的活动顶部定义SearchView searchView = null;，而不是在onCreateOptionsMenu内，而是在handleIntent内。这是完整的解决方案：

public class MainActivity extends Activity {

    SearchView searchView = null;

    @Override
    protected void onNewIntent(Intent intent) {
        setIntent(intent);
        handleIntent(intent);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.activity_main_actions, menu);

        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

        return super.onCreateOptionsMenu(menu);
    }


    private void handleIntent(Intent intent) {
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            myString = intent.getStringExtra(SearchManager.QUERY);

            searchView.onActionViewCollapsed();
            searchView.setQuery("", false);
            searchView.clearFocus();

            doStuff();
        }
    }
}

Answer 2

MenuItem searchItem = menu.findItem(R.id.menu_item_search);
SearchView mSearchView = (SearchView) menu.findItem(R.id.menu_item_search).getActionView();
       if (mSearchView!=null && searchItem!=null) {
            mSearchView.clearFocus();
            searchItem.collapseActionView();
        }

只要您在上面的代码中提交查询以关闭actionView

其他答案中大多数人遗漏的主键调用是搜索菜单项上的collapseActionView()。

对setQuery，clearFocus等的来电确实会清除视图，但会一直显示到collapseActionView - 这正是大多数人想要的。

以下是完整步骤（假设您已经拥有XML菜单项，包括标准SearchView Android文档中描述的actionViewClass）：

private SearchView mSearchView;

private MenuItem mSearchMenuItem;

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // inflate the action bar menu options, including the option that includes the search item (R.id.action_search)
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.activity_main_actions, menu);

    // get the search menu item and target view
    mSearchMenuItem = menu.findItem(R.id.action_search); // the menu item with the appropriate actionViewClass setting
    mSearchView = (SearchView) mSearchMenuItem.getActionView();

    // setup the Android SearchManager to automatically send the appropriate search intents
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

    return super.onCreateOptionsMenu(menu);
}

无论您将以下代码放入何种方法，只要您完成SearchView，请使用：

// anywhere you have a search item selected and are ready to close the search view...

// clear the search query in the toolbar so it is empty the next time the user
// opens the search view
mSearchView.setQuery("", false);  // 2nd argument is false so it doesn't re-submit a blank search query
// hide the SearchView action so the toolbar returns to normal mode showing the title and other menu items, etc.
mSearchMenuItem.collapseActionView();

Answer 4

searchView.setQuery("", false); // clear the text
searchView.setIconified(true); // close the search editor and make search icon again
