在不使用活动的情况下在两个片段之间传递数据 [英] Pass data between two fragments without using activity

问题描述

我想在不使用活动和片段活动的情况下在两个片段之间传递数据.

I want to pass data between two fragments without using activity and fragment activity.

我不想使用这样的活动在片段之间传递数据:Communicating与其他片段

I don't want to pass data between fragments using activity like this : Communicating with Other Fragments

以下是我的场景:

我有一个父片段，里面有两个子片段.现在我需要在这两个片段之间传递数据.如何实现?

I have one Parent fragment and inside that there are two child fragments.Now my need is to pass data between these two fragments.How to achieve this?

我研究了这个:事件总线但没有得到片段的工作示例.

I looked into this : Event Bus but not getting working example for fragments.

是否有其他替代方法可以在片段之间传递数据?

Is there any other alternative to pass data between fragments?

任何帮助将不胜感激.

根据 InnocentKiller 的回答进行

在 FragmentOne 中，我实现了:

In FragmentOne , I have implemented :

    FragmentTwo = new FragmentTwo();
    Bundle bundle = new Bundle();
    bundle.putString("Hello", "My name is Siddharth");
    fragment.setArguments(bundle);

在 FragmentTwo 中，我实现了:

In FragmentTwo, I have implemented :

    Bundle bundle = this.getArguments();
    String myInt = bundle.getString("Hello","Test");
    mStartTripButton.setText(myInt);

推荐答案

在activity/fragment、fragment/fragment/、activity/activity、class/class之间交换数据的最佳方式，制作一个通用的单例类，如:

Best Way to exchange data between activity/fragments, fragment/fragment/, activity/activity, class/ class, make a common singleton class like:

public class DataHolderClass {
private static DataHolderClass dataObject = null;

private DataHolderClass() {
    // left blank intentionally
}

public static DataHolderClass getInstance() {
    if (dataObject == null)
        dataObject = new DataHolderClass();
    return dataObject;
}
private String distributor_id;;

 public String getDistributor_id() {
    return distributor_id;
 }

 public void setDistributor_id(String distributor_id) {
    this.distributor_id = distributor_id;
 }
}

现在可以在移动到新屏幕之前在任何事件的任何地方(片段、活动、类)进行设置

DataHolderClass.getInstance().setDistributor_id("your data");

现在去任何地方(片段，活动，类)

 String _data = DataHolderClass.getInstance().getDistributor_id();
