I'm new to android programming The drag/ and drop feature in android studio is not working. I can't drag anything to my phone. Right now my fragment is google map view and i want to add a search bar to the view. It just doesn't drag. When I try to add it in text it says element item not allowed here?
This is my activity_maps.xml file
<fragment xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/map" tools:context=".MapsActivity" android:name="com.google.android.gms.maps.SupportMapFragment"> <item android:id="@+id/search" android:title="@string/search_title" android:icon="@drawable/ic_search" android:showAsAction="collapseActionView|ifRoom" android:actionViewClass="android.widget.SearchView" /> </fragment>

After the user releases the drag shadow, and after the system sends out (if necessary) a drag event with action type ACTION_DROP , the system sends a drag event with action type ACTION_DRAG_ENDED to indicate that the drag and drop operation is over. This is done regardless of where the user released the drag shadow.
A double tap and hold allows you to grab and then drag. A two-finger tap acts as a right click. A two-finger drag reproduces the mouse wheel scrolling action.
In most android applications where data is displayed in the form of a list format, there is a functionality with the help of which we can simply drag and drop any item from that list to any specific position within the list.
the new version of android studio uses 2 xml files for each layout. One (e.g. content_main.xml) embedded in the other one (Activity_main.xml). you should open the content_*.xml and do the design in it. hope it helps.

In addition to Hamed's answer I also had to:
File > Invalidate Caches / Restart ...
I'm missing vim.
