android 自定义ListView布局中动态加入几个TextView控件, 如何获得每个TextView来单独改变某一个TextView的文字颜色啊。

public class ListView3333 extends Activity {
/**
* @查看我发布的商品
*/
    private List<Map<String, Object>> mData;
    private ListView mListView;
    public static int count = 0;
    private MyAdapter adapter = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.main3);
     mListView=(ListView)findViewById(R.id.MyListView3);
     adapter = new MyAdapter(this);
     mListView.setAdapter(adapter);
     mListView.setItemsCanFocus(false);
     mListView.setOnItemClickListener(new OnItemClickListener(){
     @Override
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//点击列表中栏目发生的事件
     Toast.makeText(ListView3333.this, "商品描述：" + position, Toast.LENGTH_LONG).show();
     }
     });


     Button changeButton = (Button)findViewById(R.id.changebutton);
     changeButton.setOnClickListener(new Button.OnClickListener(){
     @Override
     public void onClick(View v) {

     if(count == mData.size()){
     count = 0;
     }
     Map<String, Object> map = new HashMap<String, Object>();
         //map.put("title", "这是第" + (i + 1) + "题目");
         map.put("A", count + "E选项      ");
         map.put("B", count +"F选项      ");
         map.put("C", count +"G选项      ");
         map.put("D", count +"H选项      ");
         mData.remove(count);
         mData.add(count++,map);
     adapter.notifyDataSetChanged();

                        //能够改变某个TextView的数据
                             //但是不能单独改变某个TExtView的颜色

     }
     });

    }

    @Override

     map.put("A", "A选项      ");
     map.put("B", "B选项      ");
     map.put("C", "C选项      ");
     map.put("D", "D选项      ");
     mData.add(map);
     }
    }


   class MyAdapter extends BaseAdapter{
     private LayoutInflater mInflater;

     public MyAdapter(Context context){
     this.mInflater = LayoutInflater.from(context);
     init();
     }

     @Override
     public int getCount() {
     return mData.size();
     }

     @Override
     public Object getItem(int arg0) {
     return null;
     }

     @Override
     public long getItemId(int arg0) {
     return arg0;
     }

     @Override
     public View getView(int position, View convertView, ViewGroup parent) {
//System.out.println("position: " + position);
convertView = mInflater.inflate(R.layout.my_listitem3, null);
TextView t1 = (TextView) convertView.findViewById(R.id.textView1);
TextView t2 = (TextView) convertView.findViewById(R.id.textView2);
TextView t3 = (TextView) convertView.findViewById(R.id.textView3);
TextView t4 = (TextView) convertView.findViewById(R.id.textView4);
convertView.setTag(position);
t1.setText((String) mData.get(position).get("A"));
t2.setText((String) mData.get(position).get("B"));
t3.setText((String) mData.get(position).get("C"));

--------------------编程问答-------------------- 自己把问题解决了，其实你根本不用获得那个TextView，只要你的数据改变了，你就可以通知ListView数据改变，这时候ListView就会重新加载适配器，这时你根据条件设置字体的颜色就行了。。
通知ListView数据改变代码adapter.notifyDataSetChanged();

补充：移动开发 ,  Android

android 自定义ListView布局中动态加入几个TextView控件, 如何获得每个TextView来单独改变某一个TextView的文字颜色啊 。
