フラグメントデータからAndroidのアクティビティにデータを渡す

Question

私は最初の画面としてフラグメントを使用しています。私はOnclickが私にさまざまな行動をとらなければならないボタンを持っています。ここで

は私のコードです：

HomeFragment.Java：

package info.androidhive.navigationdrawer.fragment; 

import android.content.Context; 
import android.net.Uri; 
import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 

import info.androidhive.navigationdrawer.R; 


public class HomeFragment extends Fragment { 
    // TODO: Rename parameter arguments, choose names that match 
    // the fragment initialization parameters, e.g. ARG_ITEM_NUMBER 
    private static final String ARG_PARAM1 = "param1"; 
    private static final String ARG_PARAM2 = "param2"; 

    // TODO: Rename and change types of parameters 
    private String mParam1; 
    private String mParam2; 

    private OnFragmentInteractionListener mListener; 

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

    /** 
    * Use this factory method to create a new instance of 
    * this fragment using the provided parameters. 
    * 
    * @param param1 Parameter 1. 
    * @param param2 Parameter 2. 
    * @return A new instance of fragment HomeFragment. 
    */ 
    // TODO: Rename and change types and number of parameters 
    public static HomeFragment newInstance(String param1, String param2) { 
     HomeFragment fragment = new HomeFragment(); 
     Bundle args = new Bundle(); 
     args.putString(ARG_PARAM1, param1); 
     args.putString(ARG_PARAM2, param2); 
     fragment.setArguments(args); 
     return fragment; 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     if (getArguments() != null) { 
      mParam1 = getArguments().getString(ARG_PARAM1); 
      mParam2 = getArguments().getString(ARG_PARAM2); 
     } 
    } 

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

    // TODO: Rename method, update argument and hook method into UI event 
    public void onButtonPressed(Uri uri) { 
     if (mListener != null) { 
      mListener.onFragmentInteraction(uri); 
     } 
    } 

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

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

    /** 
    * This interface must be implemented by activities that contain this 
    * fragment to allow an interaction in this fragment to be communicated 
    * to the activity and potentially other fragments contained in that 
    * activity. 
    * <p> 
    * See the Android Training lesson <a href= 
    * "http://developer.android.com/training/basics/fragments/communicating.html" 
    * >Communicating with Other Fragments</a> for more information. 
    */ 
    public interface OnFragmentInteractionListener { 
     // TODO: Update argument type and name 
     void onFragmentInteraction(Uri uri); 
    } 
} 

HomeFragment.XML

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="info.androidhive.navigationdrawer.fragment.HomeFragment"> 

    <ImageView 
     android:layout_width="100dp" 
     android:layout_height="100dp" 
     android:layout_gravity="center" 
     android:alpha="0.3" 
     android:src="@drawable/ic_home_black_24dp" /> 

    <Button 
     android:id="@+id/button" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Button" /> 

</FrameLayout> 

私も活動を追加した

package info.androidhive.navigationdrawer.activity; 

import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 
import android.view.MenuItem; 

import info.androidhive.navigationdrawer.R; 

public class ChoseFoodCourt extends AppCompatActivity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_about_us); 
     getSupportActionBar().setDisplayHomeAsUpEnabled(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(); 

     //noinspection SimplifiableIfStatement 
     if (id == android.R.id.home) { 
      // finish the activity 
      onBackPressed(); 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 
} 

Activity.JAVA人の中でifestファイル。 HomeFragment.JAVAにonclickリスナーを追加してください。どこにonclickリスナーを呼び出すか分からない。

ありがとうございます。

developers.android.comから次のコードを使用してください。 OnClickListenerがどのように機能するかについての説明もあります。質問いただきまし

public class MyActivity extends Activity { 
protected void onCreate(Bundle icicle) { 
    super.onCreate(icicle); 

    setContentView(R.layout.content_layout_id); 

    final Button button = (Button) findViewById(R.id.button_id); 
    button.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      // Perform action on click 
     } 
    }); 
} 

}
