                            .setStartTime(10, 10)
                            .setThemeDark();

                    rtpd.show(getFragmentManager(), FRAG_TAG_TIME_PICKER);

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

这意味着将父活动从扩展活动更改为扩展android.support.v4.app.FragmentActivity并使用getSupportFragmentManager()而不是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);
