이번 시간은 CustomAdpater를 활용한 전화번호부를 만드는 방법을 실습해 보겠습니다.

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ListView android:id="@+id/listView1" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_weight="1" > </ListView> </LinearLayout>

MainActivity.java

package com.example.customadaptertest; import java.util.ArrayList; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.widget.ListView; public class MainActivity extends Activity { //1.Data만들기 ArrayList<PersonInfo> phoneBook = new ArrayList<PersonInfo>(); //2.Adapter 만들기 CustomAdapter adapter; //3.ListView에 Adapter부착하기 ListView listview; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); PersonInfo person = new PersonInfo(R.drawable.minjung_144, "김민정","010-111-1111"); phoneBook.add(person); person = new PersonInfo(R.drawable.kim_144, "김태희","010-222-2222"); phoneBook.add(person); //////////////////////////////////////////////////////////////////////////////////////////// //adapter만들기 adapter = new CustomAdapter(this, R.layout.custom, phoneBook); ///// listview = (ListView)findViewById(R.id.listView1); listview.setAdapter(adapter); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } }

CustomAdapter.java

package com.example.customadaptertest; import java.util.ArrayList; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.TextView; public class CustomAdapter extends BaseAdapter { Context context; LayoutInflater Inflater; ArrayList<PersonInfo> phonebook; int layout; CustomAdapter(Context context, int layout, ArrayList<PersonInfo> phonebook){ this.context=context; Inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); this.layout = layout; this.phonebook = phonebook; } @Override public int getCount() { // TODO Auto-generated method stub return phonebook.size(); } @Override public Object getItem(int position) { // TODO Auto-generated method stub return phonebook.get(position).personName; } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub if(convertView == null){ convertView = Inflater.inflate(layout, parent, false); } ImageView img = (ImageView)convertView.findViewById(R.id.facepic); img.setImageResource(phonebook.get(position).facePic); TextView txtName = (TextView)convertView.findViewById(R.id.txtName); txtName.setText(phonebook.get(position).personName); TextView txtNumber = (TextView)convertView.findViewById(R.id.txtNumber); txtNumber.setText(phonebook.get(position).phoneNumber); return convertView; } }

PersonInfo.java (사용자 정의 Data파일)

package com.example.customadaptertest; public class PersonInfo { int facePic; String personName; String phoneNumber; PersonInfo(int facePic, String personName, String phoneNumber){ this.facePic = facePic; this.personName = personName; this.phoneNumber = phoneNumber; } }
