조각에있는 팹이 클릭 이벤트에 응답하지 않는 이유는 무엇입니까?

Question

액티비티에 포함 된 조각에 플로팅 액션 단추를 추가했습니다. 사용자가 클릭하면 새로운 활동이 시작되지만 아무 일도 일어나지 않습니다.

public class ReviewFragment extends Fragment { 

    @BindView(R.id.add_review_fab) FloatingActionButton mAddReviewButton; 

    private OnReviewNext mListener; 

    public ReviewFragment() { 
     // Required empty public constructor 
    } 

    public interface OnReviewNext { 
     void finishReview(String description); 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View view = inflater.inflate(R.layout.fragment_review, container, false); 
     ButterKnife.bind(this, view); 

     mAddReviewButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Intent intent = new Intent(getActivity(), AddReviewActivity.class); 
       startActivity(intent); 
      } 
     }); 
     return view; 
    } 

    @Override 
    public void onAttach(Context context) { 
     super.onAttach(context); 
     if (context instanceof OnReviewNext) { 
      mListener = (OnReviewNext) context; 
     } else { 
      throw new RuntimeException(context.toString() 
        + " must implement OnReviewNext"); 
     } 
    } 

    @Override 
    public void onDetach() { 
     super.onDetach(); 
     mListener = null; 
    } 
} 

왜 팹이이 활동에 의해 처리되어야, 클릭 이벤트에 응답하지 않습니다

이 조각 클래스입니다 : 여기

는 조각 레이아웃입니까?

미리 감사드립니다.

Answer 1

xml 파일에 click 이벤트를 추가하십시오.

<android.support.design.widget.FloatingActionButton 
     android:id="@+id/add_review_fab" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="bottom|end" 
     android:onClick="floatBtnClicked" 
     android:layout_margin="@dimen/fab_margin" 
     app:srcCompat="@drawable/ic_add_white_24dp" 
     android:clickable="true"/> 

그런 활동에 추가

public void floatBtnClicked(View v) { 

}

확인 프로젝트 수준 build.gradle :

buildscript { 
    repositories { 
    mavenCentral() 
    } 
    dependencies { 
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8' 
    } 
} 

확인 모듈 수준 build.gradle :

apply plugin: 'android-apt' 

android { 
    ... 
} 

dependencies { 
    compile 'com.jakewharton:butterknife:8.0.1' 
    apt 'com.jakewharton:butterknife-compiler:8.0.1' 
} 


@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View calcView = inflater.inflate(R.layout.content_main, container, false); 

     unbinder = ButterKnife.bind(this, calcView); 

     return calcView; 
    } 

    @Override 
    public void onDestroyView() { 
     super.onDestroyView(); 
     unbinder.unbind(); 
    } 


    @OnClick(R.id.mAddReviewButton) 
    public void one() { 

     Toast.makeText(getActivity(), "Working", Toast.LENGTH_SHORT).show(); 
     result.setText(result.getText().toString() + 1); 
    }

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    View view = inflater.inflate(R.layout.fragment_review, container, false); 
    ButterKnife.bind(this, view); 

    mAddReviewButton = (FloatingActionButton) view.findViewByID(R.id.addReviewFab); 

    mAddReviewButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Intent intent = new Intent(getActivity(), AddReviewActivity.class); 
      startActivity(intent); 
     } 
    }); 
    return view; 
}
