2. 로그인에 성공 후 다음과 같이 리스트뷰로 공지사항이 올라오는 것을 볼 수 있습니다.





예제 구현 시작
 
  1. res/drawable 에서 오른쪽 누르고 Vector Asset선택 후 다음과 같이 Clip Art를 선택해서 지정해줍니다.




res/drawable/ic_textsms_black_24dp.xml
아래 fillColor를 #FFFFFFFF 로 지정합니다.

<vector xmlns:android="http://schemas.android.com/apk/res/android"
        android:width="24dp"
        android:height="24dp"
        android:viewportWidth="24.0"
        android:viewportHeight="24.0">
   <path
        android:fillColor="#FFFFFFFF"
        android:pathData="M20,2L4,2c-1.1,0 -1.99,0.9 -1.99,2L2,22l4,-4h14c1.1,0 2,-0.9 2,-2L22,4c0,-1.1 -0.9,-2 -2,-2zM9,11L7,11L7,9h2v2zM13,11h-2L11,9h2v2zM17,11h-2L15,9h2v2z"/>
</vector>

res/layout/notice.xml

공지사항 리스트뷰의 내용을 채워주는 부분입니다.

Notice.java

리스트뷰에 뿌려주는 데이터를 담기 위한 클래스입니다.

package com.example.kch.registration_v7;

public class Notice
   String notice;
   String name;
    public Notice(String notice, String name, String date)
        this.notice = notice;
        this.name = name;
        this.date = date;
   
   String date;
    public String getNotice()
        return notice;
   
    public void setNotice(String notice)
        this.notice = notice;
   
    public String getName()
        return name;
   
    public void setName(String name)
        this.name = name;
   
    public String getDate()
        return date;
   
    public void setDate(String date)
        this.date = date;
   



NoticeListAdapter.java

리스트뷰에 데이터를 어떻게 뿌려줄지 구현하는 부분입니다.

package com.example.kch.registration_v7;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
import org.w3c.dom.Text;
import java.util.List;
public class NoticeListAdapter extends BaseAdapter
    private Context context;
    private List<Notice> noticedList;
    public NoticeListAdapter(Context context, List<Notice> noticedList)
        this.context = context;
        this.noticedList = noticedList;
   
    @Override
    public int getCount()
        return noticedList.size();//리스트뷰의 총 갯수
   
    @Override
    public Object getItem(int position)
        return noticedList.get(position);//해당 위치의 값을 리스트뷰에 뿌려줌
   
    @Override
    public long getItemId(int position)
        return position;
   
    //리스트뷰에서 실질적으로 뿌려주는 부분임
    @Override
    public View getView(int position, View convertView, ViewGroup parent)
       View v = View.inflate(context, R.layout.notice, null);
       TextView noticeText = (TextView)v.findViewById(R.id.noticeText);
       TextView nameText = (TextView)v.findViewById(R.id.nameText);
       TextView dateText = (TextView)v.findViewById(R.id.dateText);
       noticeText.setText(noticedList.get(position).getNotice());
       nameText.setText(noticedList.get(position).getName());
       dateText.setText(noticedList.get(position).getDate());
       v.setTag(noticedList.get(position).getNotice());
        return v;
   



 MainActivity.java

리스트뷰에 어떤 데이터를 뿌려줄지 연결하는 부분입니다.

            @Override
            public void onClick(View view)
                notice.setVisibility(View.GONE);//공지사항이 안보임
                courseButton.setBackgroundColor(getResources().getColor(R.color.colorPrimaryDark));
                statisticsButton.setBackgroundColor(getResources().getColor(R.color.colorPrimary));
                scheduleButton.setBackgroundColor(getResources().getColor(R.color.colorPrimary));
               FragmentManager fragmentManager = getSupportFragmentManager();
               FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
