I have tested this code on sdk 17 to sdk 26 code write the logic after

   setContent(R.layou.your_activity)

find the navigation view with Id

 private void setupNavigationSelection(NavigationView navigationViewList) {


    /* note : warning don't use other attribute  just checked and unchecked else         wont work*/
    int[][] states = new int[][]{
            new int[]{android.R.attr.state_checked}, // checked
            new int[]{-android.R.attr.state_checked} // unchecked
    };
    int[] colors = new int[]{
            Color.RED
            Color.GREEN,
    };

    LayerDrawable layerDrawable = getSideBarDrawable(0x80dedede);
    StateListDrawable arrowImgStates = new StateListDrawable();
    Drawable normalDrawable = new ColorDrawable(Color.TRANSPARENT);;
    arrowImgStates.addState(new int[]{android.R.attr.state_pressed}, normalDrawable);
    arrowImgStates.addState(new int[]{android.R.attr.state_focused}, layerDrawable);
    arrowImgStates.addState(new int[]{android.R.attr.state_selected}, layerDrawable);
    arrowImgStates.addState(new int[]{android.R.attr.state_checked}, layerDrawable);
    arrowImgStates.addState(new int[]{}, normalDrawable);

    ColorStateList colorStateList = new ColorStateList(states, colors);
    navigationViewList.setItemTextColor(colorStateList);
    navigationViewList.setItemIconTintList(colorStateList);
    navigationViewList.setItemBackground(arrowImgStates);

}

public LayerDrawable getSideBarDrawable(int bgColor) {
    int iSize = CLViewUtil.dpToPx(6);
    GradientDrawable gradientDrawable = new GradientDrawable();
    gradientDrawable.setShape(GradientDrawable.RECTANGLE);
    gradientDrawable.setStroke(iSize, CLThemeUtil.getThemePrimaryColor(this));
    gradientDrawable.setColor(bgColor);
    LayerDrawable layerDrawable = new LayerDrawable(new Drawable[]{gradientDrawable});
    layerDrawable.setLayerInset(0, 0, -iSize, -iSize, -iSize);
    return layerDrawable;

}
