• Make one Activity named MainActivity.java in your src folder.

import java.util.ArrayList;

import java.util.HashMap;

import android.app.Activity;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.widget.ListView;

import android.widget.SimpleAdapter;

public class MainActivity extends Activity {

ArrayList<HashMap<String, Object>> list = new ArrayList<HashMap<String,Object>>();

String [] text = {"Jelly Bean","Kitkat","Lollipop"};

Integer[] image = {R.drawable.jellybean,R.drawable.kitkat,R.drawable.lollipop};

ListView lv;

@Override

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

initializeControls();

setListView();

}

public void initializeControls(){

}

public void setListView(){

HashMap<String, Object> map = new HashMap<String, Object>();

map.put("t", text[i]);

map.put("i", image[i]);

list.add(map);

}

String[] from = {"t","i"};

int[] to = {R.id.textViewrow,R.id.imageViewrow};

SimpleAdapter adapter = new SimpleAdapter(MainActivity.this, list, R.layout.row_list, from, to);

lv.setAdapter(adapter);

}
