问题 I was wondering if it's possible to remove the automatic overlay made by the recently implemented Navigation Drawer ? (The grey layer on the second picture) 回答1: You just need to set setScrimColor(int color) to your DrawerLayout : mDrawerLayout.setScrimColor(Color.WHITE); // OR mDrawerLayout.setScrimColor(Color.TRANSPARENT); Here is the official documentation from Android API: DrawerLayout - setScrimColor(). Hope this solves your problem! : ) 来源： https://stackoverflow.com/questions/18129598
