I am a beginner in android and i had read answers of various related questions but still i am not getting it where i am wrong.

Edit 1 - Removed unusual code.

Answer 1

I think the Problem is in your Drawable Image. The error InflateException is common issue is an out of memory exception when trying to inflate an imageview loading a drawable resource. If one of this resources has a high pixel resolution it would take a lot of memory causing then an inflate exception.

So basically verify that the pixel resolution in your drawables images are just the minimum necessary for your layout.

Answer 2

I had this error message, When I was using a library called com.mikhaellopez:circularimageview and i had the image scale type set to Center_Inside

which was not supported by the library. After removing that line in the xml layout it worked fine.

Answer 3

@drawable/filebinder or @drawable/diarybookmark not a valid drawable.

Official doc: https://developer.android.com/guide/topics/resources/drawable-resource.html

Drawable could be png, jpg, gif files or drawable defined by a XML file as state drawable, shape drawable, ...

Answer 4

In my case the reason of this error was that I added the dimen resource to values-land/dimens.xml, but not in values/dimens.xml. Then IDE didn't show any warning/error but at runtime obviously the layout couldn't be drawn.

In general the best way is commenting/deletion views in the layout file one by one to realise which view causes an error.
