try this ..

 <?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" >

    <DatePicker
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:layout_marginTop="37dp"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:scaleX="1.1"
        android:scaleY="1.1"/>

</RelativeLayout>

output like this..

回答2:

you can meet your requirement by adding gravity for parent like like..

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center">

    <DatePicker
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</LinearLayout>

or else by adding layout_gravity for child as follows

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <DatePicker
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"/>
</LinearLayout>
