Navigation drawer view background color showing black background

问题

I am facing a weired issue, I have a navigation drawer activity in my app, and i found some errors with toolbar when app running on below API 21 i have fixed it by changing toolbar color.And accidently the navigation drawer color changed to black .I could not find how it changed to black in color.

Here is the navigationView

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 
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"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">

<include
    layout="@layout/app_bar_home_page_new"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header_home_page_new"
    app:menu="@menu/activity_home_page_new_drawer" />

 and the toolbar layout

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 
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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#fff"
tools:context=".NEWUI.HomePageNew">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

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

<include layout="@layout/content_home_page_new" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    app:backgroundTint="@color/colorFab"
    app:srcCompat="@drawable/ic_fab_svg" />
 </android.support.design.widget.CoordinatorLayout>

回答1:

Try to change the background-tint:

<android.support.design.widget.NavigationView
 android:id="@+id/nav_view"
 android:layout_width="wrap_content"
 android:layout_height="match_parent"
 android:layout_gravity="start"
 android:fitsSystemWindows="true"
 app:headerLayout="@layout/nav_header_home_page_new"
 app:menu="@menu/activity_home_page_new_drawer"
 android:backgroundTint="#ffffff"/>

回答2:

Use android:background with the color you want and transparent app:itemBackground:

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header_home_page_new"
    app:menu="@menu/activity_home_page_new_drawer"
    app:itemBackground="@android:color/transparent"
    android:background="@color/your_color" />
