I'm using a TimePicker in my current project that needs the minutes to only work in half hour intervals. I'm using the time picker set to spinner mode inside a dialog box that pops up when a user clicks on an EditText. I have also tried to use NumberPickers to write more of a custom TimePicker but had minimal success because instead of getting the value that was displayed on the NumberPicker it got the position of the value displayed in the String array and displayed that instead. Below is the Activity the EditText is on.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">

</android.support.v7.widget.Toolbar>
<TextView
android:id="@+id/change_date_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/action_bar"
android:textSize="70sp"
android:gravity="center"
android:layout_centerHorizontal="true"
android:layout_marginTop="10dp"

<TextView

android:layout_height="wrap_content"
android:layout_below="@id/change_date_textview"

<Button

android:layout_below="@id/change_time_textview"
android:layout_centerHorizontal="true"
android:text="@string/search_for_avaiable_rooms"
android:onClick="searchForRoom"/>
</RelativeLayout>
Below here is the custom dialog I have written
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/dialog_time_title"
android:textSize="30sp"
android:layout_centerHorizontal="true"/>
<TimePicker
android:id="@+id/dialog_time_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:timePickerMode="spinner"
android:layout_below="@id/dialog_time_edittext"
android:layout_centerHorizontal="true"
android:layout_marginBottom="5dp"/>
<Button
android:id="@+id/dialog_enter_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/dialog_time_spinner"
android:layout_alignStart="@+id/dialog_time_spinner"
android:layout_alignEnd="@+id/dialog_time_spinner"
android:text="@string/dialog_time_confirm_time"
android:layout_marginBottom="5dp"/>
</RelativeLayout>
And then here is the Java behind the activity.

Thanks a lot for any help!
