Android Studio does not show layout preview

Question

I m using Android Studio 1 4  It has passed some time since the last time I ve created a new project in android studio and today when I did it the android studio does not show anything from the layout preview  Its a blank window and says  Nothing to show    I think it s related with the new support design library cuz I ve never seen this new  default code   I ve researched a bit and it s the new android material design guidelines       I ve already done this    updated the SDK tools cleaned the project and rebuild it invalidated and restarted caches      and still nothing   Updated   I decided to update 1 5 1 it s like this  it s giving me that rendering problem   I think it s not showing correctly the lower right button  cuz I think it s supposed to be a button with a message icon in it and in my AS just shows the message icon  correct me if I m wrong

This problem occurs due to theme compatibility issue. All you have to do is first navigate to res/values/styles.xml in the project view.There look for base application theme which by default should be the fourth line. It'd look similar to the following:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

Now, you just have to add 'Base. to the parent.

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

Go to style xml file and just add  Base  class before theme  as like   lt style name  AppTheme  parent  Base Theme AppCompat Light DarkActionBar  gt   lt  style gt     Note  Replace Theme AppCompat Light DarkActionBar to Base Theme AppCompat Light DarkActionBar  and clear project

Fast Forward to 2018 and we are still having this issue   When I had this issue with Android Studio Canary 3 2 today  this is what I did   I went to   File - gt  Settings - gt  Plugins  On the plugins list  I disabled Android Support by unchecking it   Then  I selected Apply and then  OK   After this I restarted Android Studio   On restart  I repeated the process   File - gt  Settings - gt  Plugins   But this time  on the plugins list  I enabled Android Support by checking it   Then I restarted   When Android Studio came on  I allowed Gradle do its thing  then I did   File - gt  Sync Project with Gradle Files   When this was done  I reopened my xml files or refreshed them anyhow possible and everything was fine   Yeah long route  but on a day when I have to deliver at work  It sure works   TLDR  Just disable and re-enable Android Support and you will be fine

Switch from Blank Activity and use Empty Activity  Change your theme to for example Holo Light NoActionBar     Unlike Blank  Empty is more stripped down thus you may need to add some stuff yourself  Such as add the 2 Override methods onCreateOptionsMenu and onOptionsItemSelected yourself if you need to manipulate controls on the ActionBar and such  Otherwise  no other significant difference

Choose another theme  other than Holo  for example Theme   When you create the style incorrectly or from an existing style  this problem usually occurs  So select the  quot Graphical Layout quot  select  quot AppTheme quot   The tab with a blue star   And select any of the predefined style  In my case  quot Light quot  which should resolve the problem  Try to  Invalidate caches  amp  restart    Restart your Android Studio by choosing this option  It may take some time  Then  if still doesn t work try to rebuild your project
