如何片段之间传递数据，并在新片段找回？ [英] How to pass data between fragments and retrieve it in the new fragment?

问题描述

我currentley推出新的活动，并通过数据liek这样的：

I am currentley launching new activities and passing data liek this:

Intent myIntent = new Intent(c, TastePage.class);
myIntent.putExtra("taste", tempTaste);
c.startActivity(myIntent);

，然后检索新活动的数据：

and then retrieving the data in the new activity with:

 //get data from listview
Bundle extras = getIntent().getExtras();
String taste = extras.getString("taste");

为了遵循Android设计指南更好的我实现导航抽屉，改变了我的活动成了碎片。我只是对如何片段之间传递数据有点困惑。

In order to follow android design guidelines better I am implementing a navigation drawer and changing my activities into fragments. I am just a little confused on how to pass data between fragments.

有关加载新的片段我用这code：

For loading new fragments I am using this code:

FragmentManager man=getFragmentManager();
                FragmentTransaction tran=man.beginTransaction();
                Fragment_two=new BPTopTastes();
                tran.replace(R.id.main, Fragment_two);//tran.
                tran.addToBackStack(null);
                tran.commit();

我能实现成code将数据传递到新的片段，我怎么可以检索新的片段数据？

what can I implement into that code to pass data to the new fragment, and how can I retrieve that data in the new fragment?

推荐答案

使用捆绑：

从源代码片段发送数据

Fragment fragment = new Fragment();
final Bundle bundle = new Bundle();
bundle.putString("user_name", myusername);
fragment.setArguments(bundle);

和来自目的片段阅读

Bundle args = getArguments();
if (args  != null && args.containsKey("user_name"))
String userName = args.getString("user_name");
