如何从Android设备的右侧删除右侧弹出菜单的空间

Question

我的右侧弹出菜单留下了一些我不想要的空间。有没有办法做到这一点。我尝试了很多主题，但没有得到任何解决方案。如果有人能给我一些解决方案，那将会有所帮助

我的xml是

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:background="?attr/colorPrimary"
        android:padding="4dp"
        android:minHeight="?attr/actionBarSize"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

        <ImageButton
            android:id="@+id/imageView4"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:background="#f04d3c"
            android:layout_gravity="right"
            android:layout_alignParentRight="true"
            android:src="@drawable/search_icon" />

        <ImageButton
            android:id="@+id/imageView5"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_marginRight="2dp"
            android:background="#f04d3c"
            android:layout_gravity="right"
            android:layout_alignParentRight="true"
            android:src="@drawable/cart_icon" />

        <ImageButton
            android:id="@+id/imageView3"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:background="#f04d3c"
            android:layout_gravity="right"
            android:layout_marginRight="2dp"
            android:layout_alignParentRight="true"
            android:src="@drawable/notification_icon" />





    </android.support.v7.widget.Toolbar>

    <android.support.v4.widget.DrawerLayout
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/toolbar">



        <ExpandableListView
            android:id="@+id/navList"
            android:layout_width="270dp"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:layout_marginLeft="25dp"
            android:layout_marginRight="25dp"
            android:dividerHeight="1dp"
            android:divider="@drawable/list_divider"
            android:childDivider="@drawable/child_list_divider"
            />


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


</RelativeLayout>

我的风格是使用Theme.AppCompat.Light.NoActionBar

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <!--   your app branding color for the app bar -->
        <item name="colorPrimary">#f04d3c</item>
        <!--   darker variant for the status bar and contextual app bars -->
        <item name="colorPrimaryDark">#f04d3c</item>
        <!--   theme UI controls like checkboxes and text fields -->
        <item name="colorAccent">#FF4081</item>
    </style>
</resources>

我的形象是错误的
