Android 控件 ListView 用法

示例代码：

这是一个读取联系人的代码：

[java]
package com.ui.domain;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.database.Cursor;
import android.database.DataSetObserver;
import android.graphics.Color;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.EditText;
import android.widget.ListAdapter;
import android.widget.ListView;

public class CallPhone extends Activity {



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.call_phone);
        //联系人列表
        final List<String> dataList=new ArrayList<String>();
           // 获得所有的联系人
        Cursor cur = getContentResolver().query(
                ContactsContract.Contacts.CONTENT_URI,
                null,
                null,
                null,
                ContactsContract.Contacts.DISPLAY_NAME
                        + " COLLATE LOCALIZED ASC");
        while (cur.moveToNext()) {
               int idColumn = cur.getColumnIndex(ContactsContract.Contacts._ID);
               int displayNameColumn = cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);

               String phoneNumber=cur.getString(1);

               String disPlayName = cur.getString(displayNameColumn);
              dataList.add(disPlayName+":"+phoneNumber);
               Log.i("联系人名称：", disPlayName);
        }
        cur.close();//关闭游标

        ListView listView=(ListView)findViewById(R.id.listView1);
        listView.setAdapter(new ListAdapter() {

            @Override
            public void unregisterDataSetObserver(DataSetObserver paramDataSetObserver) {
                // TODO Auto-generated method stub

            }

            @Override
            public void registerDataSetObserver(DataSetObserver paramDataSetObserver) {
                // TODO Auto-generated method stub

            }

            @Override
            public boolean isEmpty() {
                // TODO Auto-generated method stub
                return false;
            }

            @Override
            public boolean hasStableIds() {
                // TODO Auto-generated method stub
                return false;
            }

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

            @Override
            public View getView(int paramInt, View paramView, ViewGroup paramViewGroup) {
                // TODO Auto-generated method stub
       &n
