workdetails.java

        edittext timein = (edittext) findviewbyid(r.id.edittext6);         edittext timeout = (edittext) findviewbyid(r.id.edittext7);         timein.setonfocuschangelistener(new view.onfocuschangelistener() {             @override             public void onfocuschange(view v, boolean hasfocus) {                 if (hasfocus) {                     timepick time = new timepick(v);                     fragmenttransaction ft = getfragmentmanager().begintransaction();                     time.show(ft, "timepicker");                 }             }         });           timeout.setonfocuschangelistener(new view.onfocuschangelistener(){             @override             public void onfocuschange(view v,boolean hasfocus) {                 if (hasfocus) {                     timepick time = new timepick(v);                     fragmenttransaction ft = getfragmentmanager().begintransaction();                     time.show(ft, "timepicker");                  }             }         }); 

timepick.java

public class timepick extends dialogfragment implements timepickerdialog.ontimesetlistener {    edittext time;      public timepick(view view)     {        time=(edittext)view;     }      public dialog oncreatedialog(bundle savedinstancestate)     {         final calendar c= calendar.getinstance();         int hour=c.get(calendar.hour_of_day);         int minute=c.get(calendar.minute);         return new timepickerdialog(getactivity(),this,hour,minute, dateformat.is24hourformat(getactivity()));     }      public void ontimeset(timepicker view,int hourofday, int minute)     {          time.settext(integer.tostring(hourofday) + ":" + integer.tostring(minute));     }   } 

workdetails.xml

<edittext         android:layout_width="140dp"         android:layout_height="wrap_content"         android:id="@+id/edittext6"         android:layout_x="147dp"         android:layout_y="170dp"         android:hint="select time"         android:clickable="true"/>      <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:textappearance="?android:attr/textappearancelarge"         android:text="time in"         android:id="@+id/textview7"         android:layout_x="23dp"         android:layout_y="184dp" />      <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:textappearance="?android:attr/textappearancelarge"         android:text="time out"         android:id="@+id/textview8"         android:layout_x="23dp"         android:layout_y="247dp" />      <edittext         android:layout_width="143dp"         android:layout_height="wrap_content"         android:id="@+id/edittext7"         android:layout_x="147dp"         android:layout_y="241dp"         android:hint="select time"/> 

you can calculate hours of day concat time hours , min (.) dot >> later parse float >> , make differance. here working code snippet.

        float end = float.parsefloat("21.00");         float start = float.parsefloat("10.00");          system.out.println(end-start); 

change method like:

public void ontimeset(timepicker view,int hourofday, int minute)     {          time.settext(integer.tostring(hourofday) + "." + integer.tostring(minute));     } 

and value later edittext.gettext();

edit:

make timein edittext variable static , value of while setting timeout this..

    public void ontimeset(timepicker view,int hourofday, int minute)         {              time.settext(integer.tostring(hourofday) + "." + integer.tostring(minute));            if(time.getid==r.id.edittext7){             if(youractivity.timein !=null){             string timein = youractivity.timein.gettext().tostring();              float end = float.parsefloat(time.gettext().tostring);             float start = float.parsefloat(timein);              system.out.println(end-start);            // need calculated hours          }         }         }
