Android扩展的SearchView使其他ActionBar项目消失

Question

我在Fragment调用的Contextual Action Bar中面临一些SearchView的问题.主要的一点是,当我的SearchView被展开时,它会消除操作栏中的所有其他项目(除了关闭按钮),即使有一些未使用的空间,就像你在这个截图中看到的那样:

此外,我也遇到了与此问题中讨论的完全相同的问题: ActionBar总是使用里面的图标扩展SearchView

这是我的SearchView的XML代码:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item android:id="@+id/menu_series_cab_search"
        android:icon="@drawable/ic_search"
        android:title="@string/action_search"
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="ifRoom"/>
    <item android:id="@+id/action_settings"
        android:title="@string/action_settings"
        android:orderInCategory="100"
        app:showAsAction="never" />
</menu>

这是我的Fragment的JAVA代码,它实现了ActionMode.Callback

@Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
    mode.getMenuInflater().inflate(R.menu.menu_series_cab, menu);
    mSearchView = (SearchView) MenuItemCompat
            .getActionView(menu.findItem(R.id.menu_series_cab_search));
    mSearchView.setQueryHint(getResources().getString(R.string.action_search));
    mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String s) {
            mSearchView.clearFocus();
            return true;
        }

        @Override
        public boolean onQueryTextChange(String s) {
            return false;
        }
    });
    mSearchView.setIconifiedByDefault(false);
    return true;
}

@Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
    mSearchView.requestFocus();
    return true;
}

首先,searchview小部件具有最大固定大小,因此空白空间是不可避免的.

如果你想在搜索视图崩溃时你的"action_settings"项目没有消失,你需要设置app:showAsAction ="always"

<?xml version="1.0" encoding="utf-8"?>

<item android:id="@+id/menu_series_cab_search"
    android:icon="@drawable/ic_search"
    android:title="@string/action_search"
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="ifRoom|collapseActionView"/>
<item android:id="@+id/action_settings"
    android:title="@string/action_settings"
    android:icon="@drawable/abc_ic_menu_moreoverflow_mtrl_alpha"
    app:showAsAction="always" />

你的Java代码应该是这样的:

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    inflater.inflate(R.menu.main, menu);


    MenuItem searchItem = menu.findItem(R.id.action_search);
    // Get the SearchView and set the searchable configuration
    searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);
    searchView = (SearchView) MenuItemCompat.getActionView(searchItem);//MenuItemCompat.getActionView(searchItem);//menu.findItem(R.id.action_search).getActionView();
    // Assumes current activity is the searchable activity
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
    searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default

    super.onCreateOptionsMenu(menu, inflater);
}
