Error: Attribute not allowed here.

[Dujana-Abrar]

activity_main.xml is giving an error when setting the height and width of the layout:- Attribute android:layout_width and android:layout_height is not allowed here. And it is also showing in setting the TextView :- Element TextView is not allowed here.

Here is the code in activity_main.xml.

I also have the same issue but couldn't find any solution till now.
What I have tried is.

• close and reopen manifest file and activity_main.xml as it is suggested in stackoverflow.
• change sdk version and re-sync project.

The same Problem I was Facing but I use the following trick that worked for me.

Go to File Section then click on Invalidate Caches/Restart

I hope After doing this issue should be solved.

@gOgRABgEEK so I think the last option remains is copy the content of your project to somewhere else and delete the existing project and create new one and paste the content.
For my some project making on Android Studio there is some problemn with emulator but I follow the above thing and suprisingly it worked for me though I still don't know what the actual problemn was but currently it is working perfectly.
