How to fix "No Suggestion" on ctrl+space on xml file android studio?

Question

I can't get any suggestion from my xml layout file. What must I do to fix the problem?

I have tried to invalidate/restart Android studio, enable and disable, deleting build folder, .idea folder, .iml file, and I have tried to make a new project but the suggestion still not show up.

I just want to show suggestion like before normally.

[EDIT]

And every time i select TextView or EditText the element not making layout_width and height automatically.

How I Solved It!

Everybody maybe had a different way of solving this problem. But for me after doing so many experiments, the last thing I do is going to delete configuration setting for Android Studio on "C:\Users\.AndroidStudio" then all fixed for me.

Answer 1

I have tried different things(deleting .idea folder and .iml files from the project, invalidate cache and restart the Android Studio) nothing worked.

Finally I close the Android Studio and navigate to android studio installation directory(i.e C:\Users\Your Username\.AndroidStudio3.3\system) delete the Cache folder, run the android studio and it's works for me.

Answer 2

Have the same issue, delete caches, invalidate caches or disable power mode is not work for me

I change compileSdk from 33 to 30

and it's work

I use Android studio chipmunk | 2021.2.1 Patch 1

Maybe new feature still not work properly or something. If anyone can explain this will be very helpfull

Answer 3

Normally, you will not get suggestions until your project is rightly indexed. So before the indexing is complete, you will see this problem. Once the indexing of files is complete, you should be able to see the suggestions.

However, if the indexing is complete and you still do not get the suggestion, I would like to recommend to install the latest version of Android Studio again and do not import any settings from your previous version.

You can also try looking for if the Power Saving Mode and invalidating the cache. This post addresses the same issue I think where you might have a look as well.

first solution

deleting .idea folder and all .iml files from the project, restarting Android Studio and rebuilding gradle did the trick. Autocomplete in XML support library is working again.

Second Solution

Just navigate to your android studio installation directory, i.e,

your drive path:/.AndroidStudio3.4/system

inside system folder.. DELETE CATCH FOLDER
