Question

下面的布局不显示搜索图标只显示另一个图标，搜索来自其他图标的下拉菜单。我想将其作为操作栏中的单独图标

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.example.diveintojava1.MainActivity" >


<item android:id="@+id/search"
      android:title="search"
      android:icon="@drawable/search1"
      android:actionViewClass="android.support.v7.widget.SearchView"
      android:showAsAction="collapseActionView|ifRoom"
       />

  <item android:id="@+id/file"
      android:title="drop"
      android:icon="@drawable/moremenu" >

    <menu>
        <item android:id="@+id/create_new"
              android:title="java" />
        <item android:id="@+id/open"
              android:title="rate us" />
    </menu>
</item>
</menu>

以下是实现菜单的java代码

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);
    MenuItem searchItem = menu.findItem(R.id.search);
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
    return true;
}
