Question

我在Android studio 1.1工作，我试图在我的工具栏中包含一个搜索选项，选项搜索显示在下拉菜单中，而不是像工具图标一样显示在工具栏中。我需要在右侧的工具栏中放置图标搜索，靠近三个菜单选项。

这是我的xml活动代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.example.xxxxx.myapplication.MainActivity" >

    <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        android:minHeight="?android:attr/actionBarSize"
        android:background="#ff7fb4ff"

        />

    <android.support.v4.widget.DrawerLayout
        android:id="@+id/drawerLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#ffffffff">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:weightSum="1">

    </LinearLayout>

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_gravity="left" >

            <ListView
                android:id="@+id/mimenu"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                android:divider="#eee"
                android:dividerHeight="1dp"
                android:background="#ffa6d0ff" />

    </RelativeLayout>

</android.support.v4.widget.DrawerLayout>

</LinearLayout>

我的风格xml

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

        <item name="colorPrimary">#005500</item>

        <item name="android:textColorPrimary">#FFFFFF</item>

        return true;

    }


    @Override

        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
