2.取消DrawerLayout滑出时菜单区（Menu）边缘阴影效果：
如图中Menu区域边缘阴影效果
源码：
android\support\v4\widget\DrawerLayout.java:
/**
* Set a simple drawable used for the left or right shadow. The drawable provided must have a
* nonzero intrinsic width. For API 21 and above, an elevation will be set on the drawer
* instead of using the provided shadow drawable.
*
* <p>Note that for better support for both left-to-right and right-to-left layout
* directions, a drawable for RTL layout (in additional to the one in LTR layout) can be
* defined with a resource qualifier "ldrtl" for API 17 and above with the gravity
* {@link GravityCompat#START}. Alternatively, for API 23 and above, the drawable can
* auto-mirrored such that the drawable will be mirrored in RTL layout.</p>
*
* @param resId Resource id of a shadow drawable to use at the edge of a drawer
* @param gravity Which drawer the shadow should apply to
*/
public void setDrawerShadow(@DrawableRes int resId, @EdgeGravity int gravity) {
setDrawerShadow(ContextCompat.getDrawable(getContext(), resId), gravity);
}
解决办法：
自定义一个阴影效果
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
