Answer 1

add your NavigationView android:fitsSystemWindows="false"

Answer 2

Add top margin of action bar size in your layout, like

<ExpandableListView
    android:groupIndicator="@null"
    android:id="@+id/left_drawer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    android:headerDividersEnabled="false"
    android:layout_marginTop="?attr/actionBarSize"
    android:childDivider="#00000000"
   />

Answer 3

i solved this by using this. thanks for the comment to set navigation view below toobar.

   // Calculate ActionBar height
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            TypedValue tv = new TypedValue();
            int actionBarHeight = 0;

            if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true)) {
                actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data, getResources()
                        .getDisplayMetrics());
            }
            ViewGroup.MarginLayoutParams mlp = (ViewGroup.MarginLayoutParams) expandableListView
                    .getLayoutParams();

            mlp.setMargins(0, actionBarHeight, 0, 0);
            expandableListView.setLayoutParams(mlp);
        }
