android - PopupView.showAtLocation is undefined for the type View -


i working on app in display contextmenu. now, when 1 of menu items in contextmenu pressed, display popupwindow. have found examples of how use popupwindow on internet still have problem. have following code:

layoutinflater layoutinflater = (layoutinflater) getbasecontext().getsystemservice(layout_inflater_service); view popupview = layoutinflater.inflate(r.layout.popup, null); final popupwindow popupwindow = new popupwindow(popupview, layoutparams.wrap_content, layoutparams.wrap_content); popupview.showatlocation(this.findviewbyid(r.id.main_layout), gravity.center, 0, 0);

and in activity's xml file:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/main_layout"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical"     android:background="#232323" >  ....  </relativelayout>

i thought should work, following error message:

"the method showatlocation(view, int, int, int) undefined type view"

what mean? giving showatlocation view , 3 integers, right? what's problem? guys have ideas?

you calling popview. instead should call popupwindow.

this method popupwindow not view
