/layout/frag_detail.xml 생성

<?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">

    <TextView
        android:id="@+id/txtName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="TextView" />
</LinearLayout>

<?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">

<TextView

android:id="@+id/txtName"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:text="TextView" />

</LinearLayout>

FragDetail 클래스 생성

public class FragDetail extends android.support.v4.app.Fragment {

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.frag_detail, container, false);

        return view;
    }
}

public class FragDetail extends android.support.v4.app.Fragment {

@Nullable

@Override

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

View view = inflater.inflate(R.layout.frag_detail, container, false);

return view;

}

FragList 클래스 수정

public class FragList extends android.support.v4.app.Fragment{
    ArrayList<AddrDTO> arList;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.frag_list, container, false);

        AddrDTO dto = new AddrDTO();
        AddrDAO dao = new AddrDAO(getContext());

        arList = dao.getArrayList("");
        ListView listView = view.findViewById(R.id.lstView);
        AddrAdapter adapter = new AddrAdapter(this.getContext(), arList);
        listView.setAdapter(adapter);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                //Toast.makeText(getContext(), ""+arList.get(position).name, Toast.LENGTH_SHORT).show();
                Fragment fragDetail = new FragDetail();
                Bundle bundle = new Bundle();
                bundle.putInt("id", arList.get(position)._id);
                fragDetail.setArguments(bundle);
                FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
                ft.replace(R.id.container, fragDetail);
                ft.commit();
            }
        });


        return view;
    }
}

public class FragList extends android.support.v4.app.Fragment{

ArrayList<AddrDTO> arList;

@Nullable

@Override

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

View view = inflater.inflate(R.layout.frag_list, container, false);

AddrDTO dto = new AddrDTO();

AddrDAO dao = new AddrDAO(getContext());

arList = dao.getArrayList("");

ListView listView = view.findViewById(R.id.lstView);

AddrAdapter adapter = new AddrAdapter(this.getContext(), arList);

listView.setAdapter(adapter);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override

public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

//Toast.makeText(getContext(), ""+arList.get(position).name, Toast.LENGTH_SHORT).show();

Fragment fragDetail = new FragDetail();

Bundle bundle = new Bundle();

bundle.putInt("id", arList.get(position)._id);

fragDetail.setArguments(bundle);

FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();

ft.replace(R.id.container, fragDetail);

ft.commit();

}

});

return view;

}

ListView의 item을 클릭했을때의 리스너 연결
listView.setOnItemClickListerner(new 까지 쓰고 Ctrl+Space를 누르고 마우스로 선택
public void onItemClick(AdapterView<?> parent, View view, int position, long id) 의 매개변수가 다르면 parent, position, id로 수정
FragDetail 클래스로 id를 전송하는 부분

Bundle bundle = new Bundle(); bundle.putInt("id", arList.get(position)._id); fragDetail.setArguments(bundle);

1
2
3

Bundle bundle = new Bundle();
bundle.putInt("id", arList.get(position)._id);
fragDetail.setArguments(bundle);

AddrDAO 클래스에 다음 메서드 추가

// 테이블 전체 내용을 ArrayList로
public AddrDTO getRecord(int id) {
	AddrDTO dto = new AddrDTO();

	SQLiteDatabase db = getConn();
	String sql;
	Cursor cursor;

	sql = "SELECT * FROM `" + tableName + "` WHERE `_id` = " + id + ";";
	cursor = db.rawQuery(sql, null);

	while(cursor.moveToNext()){
		dto._id = cursor.getInt(cursor.getColumnIndexOrThrow("_id"));
		dto.name = cursor.getString(cursor.getColumnIndexOrThrow("name"));
		dto.tel = cursor.getString(cursor.getColumnIndexOrThrow("tel"));
		dto.hp = cursor.getString(cursor.getColumnIndexOrThrow("hp"));

		break;
	}
	cursor.close();
	// 목록 작성 끝

	return dto;
}// getRecordDTO()

// 테이블 전체 내용을 ArrayList로

public AddrDTO getRecord(int id) {

AddrDTO dto = new AddrDTO();

SQLiteDatabase db = getConn();

String sql;

Cursor cursor;

sql = "SELECT * FROM `" + tableName + "` WHERE `_id` = " + id + ";";

cursor = db.rawQuery(sql, null);

while(cursor.moveToNext()){

dto._id = cursor.getInt(cursor.getColumnIndexOrThrow("_id"));

dto.name = cursor.getString(cursor.getColumnIndexOrThrow("name"));

dto.tel = cursor.getString(cursor.getColumnIndexOrThrow("tel"));

dto.hp = cursor.getString(cursor.getColumnIndexOrThrow("hp"));

break;

}

cursor.close();

// 목록 작성 끝

return dto;

}// getRecordDTO()

FragDetail 클래스 수정

public class FragDetail extends android.support.v4.app.Fragment {
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.frag_detail, container, false);

        Bundle bundle = getArguments();
        int id = bundle.getInt("id");

        AddrDAO dao = new AddrDAO(getContext());
        AddrDTO dto = dao.getRecord(id);

        ((TextView)view.findViewById(R.id.txtName)).setText(dto.name);

        return view;
    }
}

public class FragDetail extends android.support.v4.app.Fragment {

@Nullable

@Override

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

View view = inflater.inflate(R.layout.frag_detail, container, false);

Bundle bundle = getArguments();

int id = bundle.getInt("id");

AddrDAO dao = new AddrDAO(getContext());

AddrDTO dto = dao.getRecord(id);

((TextView)view.findViewById(R.id.txtName)).setText(dto.name);

return view;

}

전송된 id를 받는 부분

Bundle bundle = getArguments(); int id = bundle.getInt("id");

1
2

Bundle bundle = getArguments();
int id = bundle.getInt("id");
