I have a custom Layout shown below and I would like to update the TextViews text from within that layout file. But the TextView is not within the layout file at all.Sorry I don't know how to properly describe what I am implementing. If anyone could even advise on the correct terminology that would be much appreciated.Basically I want to change the TextView from AM to PM when the button that is inflated from com.grogorian.android.control.MinutePicker is clicked. I am using the below java within com.grogorian.android.control.MinutePicker,but keep getting a null pointer\[code\]<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/L" android
