java - add views programmatically on DialogFragment leaves empty space -

given have custom dialog class extends dialogfragment. suppose have dialog shows doctor information in it, has booking schedules consist of string arraylist shows available date.

in layout have prepared placeholder image, name, , have prepared vertical linear layout addviews programmatically of arraylist java class.

i looping list addview linearlayout

    private doctor doctor; // has doctor.schedule = arraylist<string>      @override     public view oncreateview(layoutinflater inflater, @nullable viewgroup container, @nullable bundle savedinstancestate) {         layoutsearchdoctordialogbinding binding = databindingutil.inflate(inflater, r.layout.layout_search_doctor_dialog, container, true);         getdialog().getwindow().requestfeature(window.feature_no_title);         binding.layoutschedule.removeallviewsinlayout();         (schedule schedule : doctor.schedule) {             view view = inflater.inflate(r.layout.item_schedule, null);             textview textdays = (textview) view.findviewbyid(r.id.text_days);             textview texthours = (textview) view.findviewbyid(r.id.text_hours);             textdays.settext(schedule.day);             texthours.settext(schedule.hours);             binding.layoutschedule.addview(view,                     new viewgroup.layoutparams(viewgroup.layoutparams.match_parent,                             viewgroup.layoutparams.match_parent));         }         binding.setviewmodel(new searchdoctordialogviewmodel(doctor));         binding.btncall.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 ((searchdoctorview) getactivity()).checkrecords(doctor.phonenumber);                 dismiss();             }         });         return binding.getroot();     } 

here dialog layout r.layout.layout_search_doctor_dialog

<linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="vertical"     android:padding="@dimen/dimen_16dp">      <com.bloonerd.rspondokindah.custom.circleimageview         android:layout_width="@dimen/dimen_60dp"         android:layout_height="@dimen/dimen_60dp"         android:layout_margintop="@dimen/dimen_20dp"         android:layout_marginbottom="@dimen/dimen_20dp"         android:layout_gravity="center"         app:imageurl="@{viewmodel.image}"/>      <textview         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:gravity="center"         tools:text="michael jackson"         android:text="@{viewmodel.doctorname}"         android:textstyle="bold"         android:textcolor="@color/black"         android:ellipsize="end"         android:textsize="@dimen/dimen_16sp"/>      <!-- linear layout below addviews -->     <linearlayout         android:id="@+id/layout_schedule"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="vertical"         android:paddingleft="@dimen/dimen_16dp"         android:paddingright="@dimen/dimen_16dp"/>  </linearlayout> 

also adding linearlayout addview r.layout.item_schedule

<linearlayout  xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">  <textview         android:id="@+id/text_days"         style="@style/width0heightwrapstyle"         android:textsize="@dimen/dimen_16sp"         android:textcolor="@color/text_small"/>      <textview         android:id="@+id/text_hours"         style="@style/wrapcontentstyle"         android:textsize="@dimen/dimen_16dp"         android:textcolor="@color/text_small"/>  </linearlayout> 

when debug it, shows looping doctor.schedule , adding view. shows first index of string arraylist. leaves empty spaces in linearlayout looks string arraylist added hidden.

moreover, after check uiautomatorviewer there one child view inside layout_schedule linearlayout

i realize specific dialogfragment, in recyclerview can show list fine
