this spinner code cause problem. in below mentioned assignmentdetailsactivity class, showdamageditementrypopup() method

    statusspinner = (spinner)popupview.findviewbyid(r.id.popup_status_spinner);     arrayadapter<string> statusspinnerarrayadapter = new arrayadapter<string>(assignmentdetailsactivity.this, android.r.layout.simple_spinner_item, statusspinnerarray);     statusspinnerarrayadapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item);     statusspinner.setadapter(statusspinnerarrayadapter); 

this method creates popup in assignmentdetailsactivity class

the workaround find use spinner in dialog mode

android:spinnermode="dialog"
