활동/단편에서 활동/단편으로 텍스트를 보낼 때 오류가 발생합니다.

Question

하나의 단편에서 다른 단편으로 정보를 보내는 약간의 문제가 있습니다. 스 와이프 탐색을 사용하여 프로젝트를 만들었습니다. 하나의 단편에는 버튼 만 있습니다. 다른 단편에는 텍스트 뷰만 있습니다. fragment1에있는 버튼을 클릭하면 fragment2에 텍스트를 보내려고합니다. 나는 인터페이스로 시도했지만, 내가 뭘 잘못하고 있는지 모르겠다.

다음은 현재 코드입니다.

인터페이스들 :

public interface ActivityCommunicator { 

    public void passDataToActivity(String someValue); 

} 


public interface FragmentCommunicator { 

    public void passDataToFragment(String someValue); 

} 

MainActivity :

public class MainActivity extends FragmentActivity implements ActivityCommunicator { 

public FragmentCommunicator fragmentCommunicator; 
SectionsPagerAdapter mSectionsPagerAdapter; 
Button btn; 
ViewPager mViewPager; 

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

    btn = (Button)findViewById(R.id.button1); 
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager()); 

    // Set up the ViewPager with the sections adapter. 
    mViewPager = (ViewPager) findViewById(R.id.pager); 
    mViewPager.setAdapter(mSectionsPagerAdapter); 
} 

private void SendText(View v) { 

    if(fragmentCommunicator != null) { 

     fragmentCommunicator.passDataToFragment("Hi from FragmentActivity"); 
    } 
} 

@Override 
public void passDataToActivity(String someValue) { 
    // TODO Auto-generated method stub 
} 
} 

Fragment1 :

public class Fragment1 extends Fragment { 

Button btn; 

public Fragment1(int position) { 
    // TODO Auto-generated constructor stub 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

    View v = inflater.inflate(R.layout.fragmen1, container, false); 
    btn = (Button)v.findViewById(R.id.button1); 
    return v; 
} 
} 

Fragment2 :

fragment1.xml :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<Button 
    android:id="@+id/button1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:onClick="SendText" 
    android:text="Button" /> 

</LinearLayout> 

fragment2.xml :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<TextView 
    android:id="@+id/textView1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Large Text" 
    android:textAppearance="?android:attr/textAppearanceLarge" /> 

</LinearLayout> 

main.xml :

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/pager" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context=".MainActivity" > 

<!-- 
This title strip will display the currently visible page title, as well as the page 
titles for adjacent pages. 
--> 

<android.support.v4.view.PagerTitleStrip 
    android:id="@+id/pager_title_strip" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_gravity="top" 
    android:background="#33b5e5" 
    android:paddingBottom="4dp" 
    android:paddingTop="4dp" 
    android:textColor="#fff" /> 

</android.support.v4.view.ViewPager>

귀하의 버튼에 대해 onClickListener을 볼 수 있습니까? 당신이 당신의 XML 파일에했다, 내 나쁜 : 당신의 MainActivity

편집의 개인 방법 sendText를 호출하는 것 같다 D를하지만 난 여전히 생각하는 그 SendText 방법은 문제가 될 수 개인이라는 사실 .
