mainActivity如下:

package cn.testlistviewcolor;
import java.util.ArrayList;
import java.util.HashMap;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.SimpleAdapter;
//小功能:
//1 点击ListView的item时,item的颜色(或者背景图片)发生变化
//2 与此同时,item中的TextView里的字体颜色发生变化
public class MainActivity extends Activity {
    private ListView listView;
    private ArrayList<HashMap<String, Object>> arrayList;
    private HashMap<String, Object> hashMap;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		
		listView = (ListView) findViewById(R.id.listView);
		arrayList = new ArrayList<HashMap<String, Object>>();
        for(int i=0; i<5; i++) {
        	hashMap = new HashMap<String, Object>();
        	hashMap.put("data", "Test" + i);
        	arrayList.add(hashMap);
        }
        
        SimpleAdapter simple = 
        new SimpleAdapter(this, arrayList, R.layout.list_item, new String[]{"data"},new int[]{R.id.textView});
        listView.setAdapter(simple);
		
		
	}
