如何在导航抽屉本身中启用“过度滚动”（页面末尾的“跳动”动画），以及如何更改图标的颜色？

Question

Though I'm trying to build an app with the Navigation Drawer Activity from android studio's default Navigation Drawer Activity . Everything is working fine on that, but I can't see the over scroll mode in my drawer like the Google play store app. And also I can't change the image color of the navigation drawer icons (Different colors for each icon).

So, my first question is : How to add the bounce animation in the drawer?

And, my second question is : How to change the color of the drawer icons?(Different colors for each icon)

My codes (Remember one thing that I'm using Android Studio's default Navigation Drawer Activity).

-: XML :-

activity_main

<?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_main"
        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_main"
        app:menu="@menu/activity_main_drawer" />

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

activity_main_drawer

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <group android:checkableBehavior="single">
        <item android:title="@string/drawer_subtitle_01">
            <menu>
                <item
                    android:checkableBehavior="single"
                    android:id="@+id/1st"
                    android:icon="@drawable/ic_1st"
                    android:title="@string/drawer_1st" />
            </menu>
        </item>
    </group>
</menu>

-: JAVA :-

onCreate

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);

onClick

@Override
public boolean onNavigationItemSelected(MenuItem item) {
      int id = item.getItemId();
      if (id == R.id.1st) {
         toast.setText("1st option selected");
         toast.show();
      }
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}

-: Not working methodS :-

IconColors

01. app:itemIconTint="@color/colorAccent"

OverScroll

01. android:overScrollMode="always"

02. drawer.setOverScrollMode(DrawerLayout.OVER_SCROLL_ALWAYS);

03. navigationView.setOverScrollMode(NavigationView.OVER_SCROLL_ALWAYS);

04. for (int i = 0; i < drawer.getChildCount(); i++) { drawer.getChildAt(i).setOverScrollMode(View.OVER_SCROLL_ALWAYS);}

05. for (int i = 0; i < navigationView.getChildCount(); i++) { navigationView.getChildAt(i).setOverScrollMode(View.OVER_SCROLL_ALWAYS);}

06. for (int i = 0; i < drawer.getChildCount(); i++) { drawer.getChildAt(i).setOverScrollMode(DrawerLayout.OVER_SCROLL_ALWAYS);}

07. for (int i = 0; i < navigationView.getChildCount(); i++) { navigationView.getChildAt(i).setOverScrollMode(NavigationView.OVER_SCROLL_ALWAYS);}

要将抽屉图标的颜色更改回其原始颜色，只需添加以下代码（科特琳）：

drawerView.itemIconTintList = null
