我已将GitHub中的以下库集成到我的项目中：

https://github.com/jjobes/SlideDateTimePicker

它已被很好地集成,但在执行时不起作用.
我创建了以下FragmetActivity,其中只有一个启动库的按钮.单击该按钮时,它会崩溃.活动设置为具有对话主题.

<activity
            android:name=".AlertDateTimePickerParentActivity"
            android:screenOrientation="landscape"
            android:theme="@style/Theme.AppCompat.Dialog"
            android:excludeFromRecents="true"/>

FragmetActivity：

我试过在网上寻找答案,有些人指出问题是正在显示的片段(DateTime选择器),不属于封闭FragmentActivity的片段管理器.我不确定这究竟是什么意思.

有没有人有任何想法在这里可能是错的？

解决方法:

确保您只使用一种类型的FragmentManager
来自android.app.fragment的getFragmentManager()或来自android.support.v4.fragment的getSupportFragmentManager().
我也遇到了这个错误,&原因是这个.我从支持库扩展了两个,但不知何故,我从app库启动了一个,&从支持中呼唤其他人.试试看
