Контейнер код макета [container.xml]

    android:id="@+id/container" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    tools:context="pl.example.app.MainActivity" 
    tools:ignore="MergeRootFrame" > 

</FrameLayout> 

фрагмент кода макета активность [fragment_activity.xml]

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"

     android:layout_height="wrap_content" 
     android:text="Button" 
     android:onClick="onButtonClick" 
     android:layout_gravity="center"/> 

</FrameLayout> 

Основной код активности[MainActivity.java]

package pl.example.app; 

import android.support.v4.app.FragmentActivity; 
import android.support.v4.app.Fragment; 
import android.os.Bundle; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentTransaction; 
import android.view.LayoutInflater; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.view.ViewGroup; 

public class MainActivity extends FragmentActivity { 

    private FragmentManager fragmentManager = null; 
    private FragmentTransaction fragmentTransaction = null; 

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

     if (savedInstanceState == null) { 
      fragmentManager = getSupportFragmentManager(); 
      fragmentTransaction = fragmentManager.beginTransaction(); 
      fragmentTransaction.add(R.id.container, new Container()); 
      fragmentTransaction.commit(); 
     } 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 

     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

    public static class Container extends Fragment { 

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

    } 

    public void onButtonClick(View view) { 
     changefragment(R.id.fragment_next, new FragmentNext()); 
    } 

    private void changefragment(int fragmentID, Fragment fragment) { 
     fragmentTransaction = fragmentManager.beginTransaction(); 
     fragmentTransaction.replace(fragmentID, fragment); 
     fragmentTransaction.commit(); 
    } 
} 

фрагмента кода следующего макета [fragment_next.xml]

<?xml version="1.0" encoding="utf-8"?> 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/fragment_next" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    tools:context="pl.example.app.MainActivity" 
    tools:ignore="MergeRootFrame"> 

    <TextView 
     android:text="Fragment Next" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center"/> 

</RelativeLayout> 

код фрагмент [FragmentNext.java]

package pl.example.app; 

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 

/**

public class FragmentNext extends Fragment { 

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

} 

Answer 1

Там нет вида с идентификатором fragment_next в container.xml.

Ваш FrameLayout является контейнером с идентификатором android:id="@+id/container". Итак, на lcik, если вы хотите заменить новым, вы должны использовать один и тот же идентификатор.

Изменения в

changefragment(R.id.container, new FragmentNext());
