Android Studio Navigation Draw Activity

I am creating an App with a Navigation Draw Activity. In android studio, after I start a new android activity project, I select Navigation draw activity. My question is, how to a

Solution 1:

Go to res -> layout -> activity_main.xml and add the following:

   <android.support.design.widget.NavigationView
        app:itemTextColor="#A9A9A9"// text color
        android:background="#FF0000" /> // background color

---

The top part it is defined in res -> layout -> nav_header_main.xml and the same color definitions apply to it too. Look for :

<LinearLayoutandroid:background="@drawable/side_nav_bar" />

and change it to any color you want.

Solution 2:

I just made some changes.

To define the color there are two ways to use the colors file in the values ​​directory or define in hexadecimal as for example android: background = "# 84FFFF".

<android.support.design.widget.NavigationView
    android:id="@+id/ejemplo_nav_view"
    android:layout_height="match_parent"
    android:layout_width="wrap_content"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/ejemplo_nav_header"
    app:menu="@menu/ejemplo_drawer_view"
    android:background="@color/color_define"/>
