    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //调用工具类判断保存的布尔值
        boolean b = SharedUtils.getBooleanData(MainActivity.this, "flag", false);

        if (b) {   //已经进入过，现在是第二次
            handler.sendEmptyMessageDelayed(0, 3000);
        }else{    //现在是第一次
            SharedUtils.savaBooleanData(MainActivity.this, "flag", true);

        this.list = list;
    }

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

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        //设置视图
        ImageView imageView = new ImageView(context);
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        ImageLoader.getInstance().displayImage(list.get(position),imageView);
        container.addView(imageView);
        return imageView;

3. 我的：	自定义
五. 存取数据的 SharedPreferences类
package com.shared;
import android.content.Context;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;

public class SharedUtils {
   static SharedPreferences preferences;
   static String  File = "data";
   
   //保存数据的方法
   public static void savaBooleanData(Context context, String key,boolean value){
      if (preferences == null) {
         preferences = context.getSharedPreferences(File, Context.MODE_PRIVATE);
      }
      
      //获取编辑器对象
      Editor editor = preferences.edit();
      editor.putBoolean(key, value).commit();
   }
   
   //获取数据的方法
   public static boolean getBooleanData(Context context, String key,boolean defValue){
      if (preferences == null) {
         preferences = context.getSharedPreferences(File, Context.MODE_PRIVATE);
      }
      
      return preferences.getBoolean(key, defValue);
   }
}


六. 自定义工具类；（找关联代码）
七. view包下的XListView；（找关联代码）
八. 自定义的布局文件：
1. 设置字体颜色的color文件夹下的 color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_checked="true" android:color="@color/selected"></item>
    <item android:state_checked="false" android:color="@color/defaulted"></item>
</selector>

2. drawable文件夹下设置小圆点的布局文件
（1）shape_selected.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid android:color="#00b7ff"></solid>
    <corners android:radius="8dp"></corners>
    <size android:width="8dp"  android:height="8dp"></size>
</shape>

（2）shape_select_no.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid android:color="#dfdfdf"></solid>
    <corners android:radius="8dp"></corners>
    <size android:width="8dp"  android:height="8dp"></size>
</shape>


*** 主要的布局：
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
