                    rtpd.show(getFragmentManager(), FRAG_TAG_TIME_PICKER);

推荐答案

解决方案:
RadialTimePickerDialogFragment中的show方法需要v4 FragmentManager(即getSupportFragmentManager).显然，RadialTimePickerDialogFragment是一个旧类.

Solution:
The show method in RadialTimePickerDialogFragment required the v4 FragmentManager (ie. getSupportFragmentManager). Obviously, RadialTimePickerDialogFragment is an old class.

这意味着将父Activity从扩展Activity更改为扩展android.support.v4.app.FragmentActivity，并使用getSupportFragmentManager()而不是getFragmentManager().

This means changing the parent Activity from extending Activity to extending android.support.v4.app.FragmentActivity and using getSupportFragmentManager() instead of getFragmentManager().

public class editToDoItem extends android.support.v4.app.FragmentActivity
:
:
:
RadialTimePickerDialogFragment rtpd = new RadialTimePickerDialogFragment()
                .setOnTimeSetListener(editToDoItem.this)
                .setStartTime(mTP.getCurrentHour(),mTP.getCurrentMinute());

rtpd.show(getSupportFragmentManager(), FRAG_TAG_TIME_PICKER);
