从“底部工作表"对话框片段中获取价值 [英] Get value from Bottom Sheet Dialog Fragment

问题描述

我正在从片段A开始bottomSheetDialogFragment.我想从该bottomSheetDialogFragment中选择日期，然后将其设置在片段A中.

I'm starting bottomSheetDialogFragment from a fragment A. I want to select the date from that bottomSheetDialogFragment then set it in the fragment A.

选择日期已经完成，我只想将其放在片段A中以在某些字段中进行设置.

The select date is already done, I just want to get it in the fragment A to set it in some fields.

我如何获得价值?有什么建议怎么做吗?

How can I get the value? Any suggestions how to do it?

推荐答案

创建这样的接口类

public interface CustomInterface {

    public void callbackMethod(String date);
}

在您的 Activity 或 Fragment 中实现此界面.并创建此接口的对象.

Implement this interface in your Activity or Fragment. and make an object of this Interface.

private CustomInterface callback;

在 onCreate 或 onCreateView

callback=this;

现在在调用它时，在您的 BottomSheetDialogFragment 构造函数中传递此回调.

Now pass this callback in your BottomSheetDialogFragment constructor when you call it.

yourBottomSheetObject = new YourBottomSheet(callback);
yourBottomSheetObject.show(getSupportFragmentManager()," string");

现在在您的BottomSheetFragment的构造函数中

Now in your BottomSheetFragment's constructor

私有CustomInterface回调；

private CustomInterface callback;

public SelectStartTimeSheet(CustomInterface callback){

this.callback=callback;

}

最后使用此回调对象设置日期

And at last use this callback object to set your date

callback.callbackMethod("your date");

您将在 callbackMethod 函数中的片段"或活动"中接收该日期.

and yout will recieve this date in your Fragment or Your Activity in callbackMethod function.
