This is xml for layout of view.

  <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Select a time to send Message"
    android:textColor="#3B5998"
    android:textSize="20dp"
    android:textStyle="bold"
    android:layout_gravity="center_horizontal" />

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_marginTop="30dp">

        <DatePicker
            android:id="@+id/pickerdate"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
        <TimePicker
            android:id="@+id/pickertime"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
        <Button
            android:id="@+id/setalarm"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Set Alarm"/>
        <TextView
            android:id="@+id/info"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

    </LinearLayout>
</ScrollView>

Date in Java is just amount of milliseconds since January 1, 1970 00:00:00.000 GMT. So you can convert it back and forth to long variable. Date.getTime() to get long value of date (It's UNIX TimeStamp in milliseconds). And use new Date(System.currentTimeMillis()) to create your Date object back. So in the end you simply need to store one long value in your database.
