Step 5:
Create two separate variables for country list and denotation.
Step 6:
Set the content view to main and set the set the listview adapter to EfficientAdapter class.
This will load the listcontent in the listview.

[sourcecode language="java"]

import android.app.Activity;
import android.os.Bundle;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ListView;
import android.widget.TextView;

public class customlistview extends Activity {

private static class EfficientAdapter extends BaseAdapter {
private LayoutInflater mInflater;

public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);

}

public int getCount() {
return country.length;
}

public Object getItem(int position) {
return position;
}

public long getItemId(int position) {
return position;
}

public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.listview, null);
holder = new ViewHolder();
holder.text = (TextView) convertView
.findViewById(R.id.TextView01);
holder.text2 = (TextView) convertView
.findViewById(R.id.TextView02);

convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}

holder.text.setText(curr[position]);
holder.text2.setText(country[position]);

return convertView;
}

static class ViewHolder {
TextView text;
TextView text2;
}
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView l1 = (ListView) findViewById(R.id.ListView01);
l1.setAdapter(new EfficientAdapter(this));
}

private static final String[] country = { "Iceland", "India", "Indonesia",
"Iran", "Iraq", "Ireland", "Israel", "Italy", "Laos", "Latvia",
"Lebanon", "Lesotho ", "Liberia", "Libya", "Lithuania",
"Luxembourg" };
private static final String[] curr = { "ISK", "INR", "IDR", "IRR", "IQD",
