当我尝试将activity_home.xml作为设计查看时，它不会显示左抽屉，但是当我在设备上安装该应用程序时，它将在单击时显示左抽屉，但是当我单击任何时候时，它都不会显示复选框而不起作用.
When I try to view activity_home.xml as a design it will not showing left drawer but when I install the app on device it will show the left drawer on click but when I click on any time it will not showing check able box and not working.
