Android 如何将值从片段的RecyclerAdapter传递到另一个片段？
我试图将值从一个包含回收器视图的片段传递到另一个片段，该片段都是底部栏的一部分 我曾尝试使用界面来实现这一点，但我的应用程序崩溃并显示Android 如何将值从片段的RecyclerAdapter传递到另一个片段？,android,android-fragments,android-recyclerview,location,Android,Android Fragments,Android Recyclerview,Location,我试图将值从一个包含回收器视图的片段传递到另一个片段，该片段都是底部栏的一部分 我曾尝试使用界面来实现这一点，但我的应用程序崩溃并显示NullPointerException 我的第一个片段包含一个复选框和一个显示当前位置、价格的编辑文本，以及一个用作日期选择器的图像按钮 当用户选中复选框时，他可以从图像按钮将日期输入到EditText字段中。 用户可以在EditText字段中选择三个日期 我的问题是如何填写这些条目（地点、价格和日期） 传给第三个碎片 我已经参考了来实现接口 这是我的密码 Te
