I have 3 ToolBars that I use across my whole application The first one is just a ToolBar with a close button.The second one is a ToolBar with a close and delete icon.The third one is a ToolBar with a close and home icon.Here is my case, I use this ToolBar in many places, and I dont want to use Fragment for some reasons so I am forced to use Activity.For usability, I created methods to handle their functions, but I am sure I can do something to make this easier as I repeat this code in each activity.toolbar_layout.xml<?xml version=1.0 encoding=utf-8?><android.support.v7.widget.Toolbar
