NavigationView项目的ActionLayout显示在右侧

Question

I'm developing an application where I'm using new design support library's navigation view controller for drawer menu. Everything is working fine. I've set items for navigation view using app:menu attribute. Item's are perfectly displayed. Now i'm adding app:actionLayout for those item's and it's also getting added but the problem is it's getting displayed at right side in the view.

My Activity XML

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        app:popupTheme="@style/AppTheme.PopupOverlay">

        <afour.com.uniapp.customwidgets.CustomTextView
            android:id="@+id/text_toolbarTitle"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:gravity="start"
            android:text="@string/app_name"
            android:textColor="@android:color/white"
            android:textSize="20sp"
            app:FontName="@string/type_face_splash" />
    </android.support.v7.widget.Toolbar>


    <FrameLayout
        android:id="@+id/frame_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/toolbar" />

        </RelativeLayout>

<android.support.design.widget.NavigationView
    android:id="@+id/navigation_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="@android:color/holo_green_dark"
    android:paddingTop="20dp"
    app:headerLayout="@layout/navigation_header_layout"
    app:paddingStart="0dp"
    app:itemBackground="@android:color/holo_green_light"
    app:itemTextColor="@android:color/white"
    app:menu="@menu/main_menu" />

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

My menu file

<?xml version="1.0" encoding="utf-8"?>

<item
    android:id="@+id/nav_about"
    android:title="@string/aboutus"
    app:showAsAction="never" />

<item
    android:id="@+id/nav_logout"
    app:actionLayout="@layout/logout_item_layout"
    app:showAsAction="collapseActionView" />

</menu>

my action layout file

<?xml version="1.0" encoding="utf-8"?>

<ImageButton
    android:layout_width="60dp"
    android:layout_height="60dp"
    android:layout_marginLeft="10dp"
    android:layout_marginStart="10dp"
    android:background="@android:color/transparent"
    android:contentDescription="@string/aboutus"
    android:padding="05dp"
    android:src="@android:drawable/ic_menu_help" />

<afour.com.uniapp.customwidgets.CustomTextView
    android:id="@+id/text_logout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="20dp"
    android:layout_marginStart="20dp"
    android:gravity="start"
    android:text="@string/logout"
    android:textColor="@android:color/white"
    android:textSize="20sp"
    app:FontName="@string/type_face_regular" />

</LinearLayout>

PFA of the issue

Answer 1

In your action layout xml file, you can fix your problem adding to the root view (a LinearLayout in your case) the following properties:

<LinearLayout
   ...
   android:layout_gravity="start">

But take note what the documentation says about actionLayout:

android:actionLayout: Layout resource. A layout to use as the action view. https://developer.android.com/guide/topics/resources/menu-resource.html

And an actionView:

An action view is an action that provides rich functionality within the app bar. For example, a search action view allows the user to type their search text in the app bar, without having to change activities or fragments. https://developer.android.com/training/appbar/action-views.html

So maybe that's isn't the best way to display a custom view in your MenuItem.

Seeing your code, why not just add the icon and text to the item element?

<item
    android:id="@+id/nav_logout"
    android:icon="@android:drawable/ic_menu_help"
    android:text="@string/logout" />

But if you really need it, the right way to display the custom view is implementing a ListView with ViewHolder pattern.
