What is causing this trouble? The com.github.ppartisan... is from another provider, which I found in StackOverflow. Link - https://stackoverflow.com/a/41573178/1379286

Use right class name . com.example.graphs.viewchart.BarView

<com.example.graphs.viewchart.BarView
            android:id="@+id/low_bar"
            android:layout_weight="1"
            android:layout_width="0dp"
            android:layout_height="8dp" />

Then Clean-Rebuild-Run

Awesome. Thank you. Do I need this line? - tools:context="com.github.ppartisan.graphish.MainActivity"

IntelliJ Amiya Over a year ago

@PeakGen No problem .As your wish

PeakGen Over a year ago

I think I should remove. Showing error in android studio.

@PeakGen Replace with your own context.

tools:context is only used by the IDE, it is not important to the functionality of your app
