[Android] AdapterView - 3

커스텀 항목 뷰는 원하는 항목 배치에 좋다.

먼저 커스텀 레이아웃을 작성한다.

mail.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
   <TextView
        android:layout_width="wrap_content"

    <ListView

</RelativeLayout>

Item 클래스

public class Item {
 String _name;
 public Item(String name){
  this._name = name;
 }
}

Adapter 클래스

class ListAdapter extends BaseAdapter{
 Context _main;
 LayoutInflater _inflater;
 ArrayList<Item> _item;
 int _layout;
 
 public ListAdapter(Context context, int layout, ArrayList<Item> arr){
  this._main=context;
  this._inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  this._layout=layout;
  this._item=arr;
 }
 
 public int getCount(){
  return this._item.size();
 }
 
 public String getItem(int index){
  return this._item.get(index)._name;
 }
 
 public long getItemId(int index){
  return index;
 }
 
 public View getView(int index, View view, ViewGroup parent){
  final int idx = index;
  if(view==null){
   view = this._inflater.inflate(this._layout,parent,false);
  }
  TextView txtview = (TextView)view.findViewById(R.id.text);
  txtview.setText(this._item.get(idx)._name);
  
  Button btn = (Button)view.findViewById(R.id.btn);
  btn.setOnClickListener(new Button.OnClickListener(){
   public void onClick(View v){
    String str = _item.get(idx)._name;
    Toast.makeText(_main, str, Toast.LENGTH_SHORT).show();
   }
  });
  return view;
 }
}

메인 클래스

public class ImageViewActivity extends Activity{
 
 ArrayList<Item> arr;
 
 ListView list ;
    /** Called when the activity is first created. */
 @Override   
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
        arr = new ArrayList<Item>();
        Item item;
        item = new Item("first");
        arr.add(item);
        item = new Item("second");
        arr.add(item);
        item = new Item("third");
        arr.add(item);
       
        ListAdapter adapter = new ListAdapter(this,R.layout.main,arr);
        ListView list;
        list=(ListView)findViewById(R.id.list);
        list.setAdapter(adapter);
 }
}
실행을 하면 어댑터를 통하여 제어를 하는 것이 확인 가능하다.
