搜索视图关闭图标出现禁用而不是白色

Question

每当我在搜索视图中输入时,关闭按钮(X)似乎由于某种原因而被禁用,而不是以白色显示.如何解决此错误以使其显示为白色？

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_search_list, menu);
    MenuItem item = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
    searchView.setOnQueryTextListener(this);
    searchView.setQueryHint(getResources().getString(R.string.station_search_hint));
}

menu_search_list.xml

<?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/action_search"
        android:icon="@drawable/ic_action_search_light"
        android:title="@string/action_search"
        android:orderInCategory="100"
        app:showAsAction="always"
        app:actionViewClass="android.support.v7.widget.SearchView"/>
</menu>

Answer 1

你的代码看起来不错。尝试以下代码：

final MenuItem search = menu.findItem(R.id.action_search);
    if (search != null) {
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(search);
        search.expandActionView();
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                // Your Logic
                return false;
            }
        });
        MenuItemCompat.setOnActionExpandListener(search, new MenuItemCompat.OnActionExpandListener() {
            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                return false;
            }

            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                finish();
                return true;
            }
        });

另一项调整：尝试使用上面相同的代码，onPrepareOptionsMenu并在顶部添加以下额外行

menu.clear();
getMenuInflater().inflate(R.menu.menu_search_list, menu);
...
// Above code
