Menu
I accidentally created drawer_list_item.xml in the screenshot using New -> File menu, instead of New -> Layout resource file and now I can't open it as a regular layout file in design mode. It opens it as a plain text file.
Is there any way I can change its type. I couldn't find anything related to this through Android Studio's settings
File content:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
Edit for more things I tried:
recreating does not work, as it creates it the same way. But, when I recreate it after deletion it gives the following exception. I close the window and the old text file re-appears
null

if I rename the file to drawer_item.xml, it gains the icon and is seen as a layout file. If I rename it back to drawer_list_item.xml, the problem returns. So it probably indexed it somewhere as a plain text file...
.idea/workspakce.xml to .idea/workspace.xml.bk so it recreates it in case I missed something - still no luck. I even tried removing .idea folder and app.iml file from the root folder, but no fix

As you know every time you create new project with some activity, Android Studio generates a default activity_main. xml file with RelativeLayout as the root element and one TextView.
Android provides a straightforward XML vocabulary that corresponds to the View classes and subclasses, such as those for widgets and layouts. You can also use Android Studio's Layout Editor to build your XML layout using a drag-and-drop interface.
Specifically, Android considers XML-based layouts to be resources, and as such, layout files are stored in the reslayout directory inside your Android project. Each XML file contains a tree of elements specifying a layout of widgets and containers that make up one View.
Found the source of the problem - it was in the config files Android Studio creates in your home directory: ~/.AndroidStudioPreview2.0. In my case, it was ~/.AndroidStudioPreview2.0/config/options/filetypes.xml
<application>
<component name="FileTypeManager" version="16">
<ignoreFiles list="*.hprof;*.pyc;*.pyo;*.rbc;*~;.DS_Store;.git;.hg;.svn;CVS;RCS;SCCS;__pycache__;_svn;rcs;" />
<extensionMap>
<mapping pattern="drawer_list_item.xml" type="PLAIN_TEXT" />
</extensionMap>
</component>
</application>
Therefore, it seems like I somehow made Android Studio index that file name pattern drawer_list_item.xml as plain text...
Removing that mapping entry from the file solves the problem: <mapping pattern="drawer_list_item.xml" type="PLAIN_TEXT" />
