您可以通过以下方式执行此操作： -

package com.aman.sample.bubblelist;

import android.app.Activity;
import android.content.SharedPreferences;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;

public class Main extends Activity {

    String[] data = { "Sample User Data ", "Sample User Data ",
            "Sample User Data ", "Sample User Data ", "Sample User Data ",
            "Sample User Data ", "Sample User Data ", "Sample User Data ",
            "Sample User Data ", "Sample User Data ", "Sample User Data ",
            "Sample User Data ", "Sample User Data ", "Sample User Data ",
            "Sample User Data ", "Sample User Data " };
    Drawable[] usrimg = null;
    String bgimg = "", _user = "", _pass = "";
    int odd_resID, even_resID;
    ListView myList;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // finding the list view
        myList = (ListView) findViewById(R.id.myList);
        myList.setAdapter(new MyCustomAdapter());
        myList.setCacheColorHint(0);

    }

    class MyCustomAdapter extends BaseAdapter {

        @Override
        public int getCount() {
            return data.length;
        }

        @Override
        public String getItem(int position) {
            // TODO Auto-generated method stub
            return null;
        }

        @Override
        public long getItemId(int position) {
            // TODO Auto-generated method stub
            return position;
        }

        @Override
        public int getItemViewType(int position) {
            // TODO Auto-generated method stub
            return position;
        }

        @Override
        public int getViewTypeCount() {
            // TODO Auto-generated method stub
            return data.length;
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            LayoutInflater inflater = getLayoutInflater();
            View row;
            int _intPosition = getItemViewType(position);
            String even_color, odd_color;
            SharedPreferences prefList = getSharedPreferences("PrefsFile",
                    MODE_PRIVATE);
            ;
            even_color = prefList.getString("even_bubble_color", "pink");
            odd_color = prefList.getString("odd_bubble_color", "green");
            int even_color_id = getResources().getIdentifier(even_color,
                    "drawable", "com.teks.chilltwit"), odd_color_id = getResources()
                    .getIdentifier(odd_color, "drawable", "com.teks.chilltwit");
            ImageView even_view, odd_view;

            if (_intPosition % 2 == 0) {
                row = inflater.inflate(R.layout.list_row_layout_even, parent,
                        false);
                TextView textLabel = (TextView) row.findViewById(R.id.text);

                textLabel.setText(data[position]);

            } else {
                row = inflater.inflate(R.layout.list_row_layout_odd, parent,
                        false);
                TextView textLabel = (TextView) row.findViewById(R.id.text);

                textLabel.setText(data[position]);
            }

            return (row);
        }
    }

}
