Вот мой код:

package no.clausjensen.fragmentcommunication; 

import android.app.Fragment; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.Button; 

/** 
* Created by nr1 on 04/03/15. 
*/ 
public class FragmentA extends Fragment implements View.OnClickListener { 

    Button btnClick; 
    int counter = 0; 
    Communicator comm; 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){ 
     //return inflater.inflate(R.layout.fragment_a, container, false); 
     Log.d("FragmentA: ","onCreateView"); 
     View rootView = inflater.inflate(R.layout.fragment_a, container, false); 
     return rootView; 
    } 

    @Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 
     Log.d("FragmentA: ","onActivityCreated"); 
     //det finnes ikke metode for å finne byId i fragment, må man bruke activity.findView...byId 
     comm=(Communicator) getActivity(); 
     btnClick = (Button) getActivity().findViewById(R.id.btn1); 
     btnClick.setOnClickListener(this); 
    } 

    @Override 
    public void onClick(View view){ 
     Log.d("FragmentA: ","onClick"); 
     counter++; 
     comm.respond("The button was clicked " + counter + " times"); 
    } 
} 

Подробнее Код:

package no.clausjensen.fragmentcommunication; 

import android.app.Fragment; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.TextView; 

/** 
* Created by nr1 on 04/03/15. 
*/ 
public class FragmentB extends Fragment { 

    TextView txt1; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){ 
     return inflater.inflate(R.layout.fragment_b, container, false); 


    } 

    @Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 
     txt1=(TextView) getActivity().findViewById(R.id.txwText); 
    } 

    public void changeText(String txtVar){ 

     txt1.setText(txtVar); 

    } 
} 

А потом некоторые из них:

package no.clausjensen.fragmentcommunication; 

import android.app.Activity; 
import android.app.FragmentManager; 
import android.os.Bundle; 



public class MainActivity extends Activity implements Communicator { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
    } 


    @Override 
    public void respond(String data){ 
     FragmentManager fm = getFragmentManager(); 
     FragmentB frg2 = (FragmentB) fm.findFragmentById(R.id.fragment2); 
     frg2.changeText(data); 

    } 

} 

И интерфейс:

package no.clausjensen.fragmentcommunication; 

/** 
* Created by nr1 on 04/03/15. 
*/ 
public interface Communicator { 

    public void respond (String data); 
} 

Answer 1

Im идиот! Я добавил fragment_a в файле fragment_a-XML, как это:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="#99cc00"> 

    <Button 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Click me" 
     android:id="@+id/btn1" /> 

    <fragment 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:id="@+id/fragment_a" 
     android:name="no.clausjensen.fragmentcommunication.FragmentA"/> 
</LinearLayout> 

тогда конечно он будет пытаться создать новый fragment_a, внутри fragment_a ... и т.д.! NOOBME!

Answer 2

Я уверен, из StackTrace, что вы добавляете Fragmenta в layoutB и fragmentB в макет или что-то подобное
