<?xml version="1.0" encoding="utf-8"?> <relativelayout 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">      <include         android:id="@+id/toolbar"         layout="@layout/toolbar"         android:layout_width="match_parent"         android:layout_height="wrap_content" />      <scrollview         android:id="@+id/scroll_view"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_below="@+id/toolbar">          <linearlayout             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:orientation="vertical">              <datepicker                 android:id="@+id/datepicker"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:layout_gravity="center" />              <timepicker                 android:id="@+id/timepicker"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:layout_gravity="center" />          </linearlayout>     </scrollview> </relativelayout>

onresume method in datetimepickeractivity:

/* ... */ @override protected void onresume() {     super.onresume();      int width = resources.getsystem().getdisplaymetrics().widthpixels;     linearlayout.layoutparams params = (linearlayout.layoutparams) datepicker.getlayoutparams();     params.width = width;     datepicker.setlayoutparams(params); } /* ... */

try this

style.xml

<style name="dialogtheme" parent="theme.appcompat.light">         <!-- customize theme here. -->         <item name="colorprimary">@color/colorprimary</item>         <item name="colorprimarydark">@color/colorprimarydark</item>         <item name="coloraccent">@color/coloraccent</item>     </style>

mainactivity.java apply theme in constructor of date picker (r.style.apptheme)

 datepickerdialog datepickerdialog = new datepickerdialog(getactivity(), r.style.apptheme, this, year, month, day);             datepickerdialog.getdatepicker().setmaxdate(c.gettimeinmillis());             return datepickerdialog;
