为什么80%的码农都做不了架构师？>>> 
做法：去掉点击打开drawer的home，去掉滑出事件就变相去掉了draw
源码位置:framworks/base/packages/SettingLib/src/com/android/settinglib/drawer/
1、去掉home：找到Drawer，然后找到对应的toolbar,去找actionbar，让如下方法不执行就设置不上左图标了
public void showMenuIcon() {
mShowingMenu = true;
getActionBar().setHomeAsUpIndicator(R.drawable.ic_menu);
getActionBar().setHomeActionContentDescription(R.string.content_description_menu_button);
getActionBar().setDisplayHomeAsUpEnabled(true);
}
2、去掉滑动：mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
