Question

我在 API 23.Using RadialTimePickerDialogFragment 上使用了 v4 父 activity 基于 Activity （我们不需要

                            .setThemeDark();

                    rtpd.show(getFragmentManager(), FRAG_TAG_TIME_PICKER);

解决方案：
RadialTimePickerDialogFragment 中的显示方法需要 v4 FragmentManager（即 getSupportFragmentManager）。显然，RadialTimePickerDialogFragment 是一个旧的 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()。

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);
