Android ile Custom ListView oluşturabilmek için Adapter yazmamız gerekiyor. ListActivity ait create metoudunda this.setListAdapter(new MyCustomAdapter(this, liste)); şeklinde adapter ekliyoruz. Sonra istediğimiz şekilde adapterimizi düzenliyoruz. Dikkat edilmesi gereken şey ise adapter.xml de hangi component tanimlanmışsa private AdaptirSatir{} sinifinda ayni bileşenler tanimlanmalidir ve MyCustomerAdapter içindeki getView() metodundan findByIde() metodu ile erişmemiz lazım.

custom listview

MyListActivity.java

package com.custom.list;

import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ListView;
import android.widget.Toast;

public class MyListActivity extends ListActivity {
	private String[] liste = { "PYTHON", "C", "C", "C++", "C#", "MATLAB","PHP", "JAVA", "JSP", "JSF", "JPA", "SEAM", "ANDROID" };

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		this.setListAdapter(new MyCustomAdapter(this, liste));
	}

	@Override
	protected void onListItemClick(ListView l, View v, int position, long id) {
		super.onListItemClick(l, v, position, id);
		Object clicked = this.getListAdapter().getItem(position);
		String o = clicked.toString();
		Toast.makeText(getApplicationContext(), o, Toast.LENGTH_SHORT).show();
	}

}
