Won't let me add an imageView to my layout

Rendering Problems The following classes could not be found: - android.support.design.widget.RelativeLayout (Fix Build Path, Create Class) Tip: Try to build the project.

I keep getting presented with this error and when I try to drag the image view in it doesn't allow me. All help is greatly appreciated.

Hopefully it works , play around with it and edit it - you might have to go back to the design view , image - src and find the image again.

Let me know how it goes !

Hi Elliot , yes I figured it out - what happened was for some reason Android had loaded some sort of Custom Layout instead of Relative Layout and I just couldnt drag anything on to Custom Layout - I'm also a beginner haha so everything new was confusing me. I switched to xml code view and commented out all the existing code (not deleted incase I needed , but I didnt) and then copy / pasted the xml code from the mainActivity. I ended up editing it a bit and taking out some stuff but it worked - I got my relativeLayout back and could drag things onto it again.

I've got to open up Android Studio to give you in exact detail what I did (I'll try my best to remember) , but let me know if this helped before I do first .

Hi Chistiaan,

Thanks for your help. Unfortunately, android studio has loaded the custom layout to both my story and main activity therefore when I pasted the code in it was the same. If possible could I have a sample of the code you used? Would be of great help. Thanks.

Elliott.
