title: How to pass values between Fragments
body: <p>I am just trying to build a simple sample application that uses Fragments. My scenario is, I have two activities with one fragment inside each activity. The first fragment has an edittext and a button. The second fragment has a textview. When I enter a name in the edittext and click on the button, the textview in the second fragment should display the name entered in the edittext of the first fragment.</p>
  <p>I was able to send the value from first fragment to its activity and then from that activity to second activity. Now how do I use this value inside the second fragment?</p>
  <p>Here is the Java code:</p>
  <pre><code>package com.example.fragmentexample;

  import android.widget.Toast;
  
  public class Fragment_1 extends Fragment{
  
      OnFragmentChangedListener mCallback;
  
      // Container Activity must implement this interface
      public interface OnFragmentChangedListener {
          public void onButtonClicked(String name);
      }
  
      @Override
      public void onAttach(Activity activity) {
          super.onAttach(activity);
  
          // This makes sure that the container activity has implemented
          // the callback interface. If not, it throws an exception
          try {
              mCallback = (OnFragmentChangedListener) activity;
          } catch (ClassCastException e) {
              throw new ClassCastException(activity.toString()
                      + &quot; must implement OnHeadlineSelectedListener&quot;);
          }
      }

          Button btnSayHi_Fragment = (Button) view.findViewById(R.id.btnSayHi);
  
          btnSayHi_Fragment.setOnClickListener(new OnClickListener() {

                  Activity activity = getActivity();
  
                  if(activity != null)
                  {
                      Toast.makeText(activity, &quot;Say&amp;ing Hi in Progress...&quot;, Toast.LENGTH_LONG).show();

  <p>How do I get the value from the bundle in SecondActivity.java to the <em>Fragment_2.Java</em> file?</p>
