package kr.co.dothome.braverokmc.tutorial5;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

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

        String[] items ={"망고 쥬스", "토마토 쥬스", "포도 쥬스"};
       // ListAdapter listAdapter =new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, items);
        ListAdapter listAdapter =new ImageAdapter(this, items);
        listView.setAdapter(listAdapter);


        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                String item =String.valueOf(parent.getItemAtPosition(position));
                Toast.makeText(getApplicationContext(), item, Toast.LENGTH_SHORT).show();
            }
        });




    }



}

 

 

 

 

R.layout.activity_main

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

class ImageAdapter

 

핵심코드 

생성자

super()

  super(context, R.layout.image_layout, items);

 

 다음과 같이 컨텍스트 객체를  쉽게 가져올 수 있다. 

 LayoutInflater inflater = LayoutInflater.from(getContext());
