Answer 1

使用RelativeLayout与我合作

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="wrap_content"
                android:layout_height="match_parent">
    <EditText xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:id="@+id/visibility_search_edit_text"/>
</RelativeLayout>

Answer 2

试试这个

<item
        android:id="@+id/action_search"
        android:icon="@drawable/ic_action_search"
        android:title="search_title"
        app:actionViewClass="android.support.v7.widget.SearchView"
        android:actionLayout="@layout/your_layout_name"
        app:showAsAction="collapseActionView|ifRoom" />

不同之处在于showAsAction属性和actionlayout
