Currently I'm working on an Android Project consisting of Toolbar instead of the regular ActionBar.
I have defined the Toolbar in a separate layout file named as tool_bar.xml, and then I include the ToolBar in every layout where I need it.
My Activity's Layout file is named as acceptor.xml.
My Question is that, whenever I include the tool_bar.xml in acceptor.xml and provide the included layout an id, it gives me a force close error, and it goes smooth when I remove that id attribute.
Please help!
All the needed resources like Logcat, xml files, Java files are posted below :
tool_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://ift.tt/nIICcg"
