如何绑定ArrayList的对象到Android GridView的？ [英] How to bind ArrayList Objects to android GridView?

问题描述

我有数组列表对象的集合，如：

 的ArrayList＆LT;＆人GT;人=新的ArrayList＆LT;＆人GT;（）;
 

所以，我怎么可以绑定对象名单人到Android GridView控件

解决方案

  GridView控件settingGrid;
  ArrayList的＆LT;＆人GT;者;
  公共无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.setting）;   人=新的ArrayList＆LT;＆人GT;（）;    settingGrid =（GridView控件）findViewById（R.id.settinggridview）;
    settingGrid.setAdapter（新SettingImageAdapter（本））;
    settingGrid.setOnItemClickListener（新OnItemClickListener（）{
        公共无效onItemClick（适配器视图父母，视图V，INT位置，长的id）{
             }）; 公共类SettingImageAdapter延伸BaseAdapter {
    上下文MyContext;    公共SettingImageAdapter（上下文_MyContext）{
        MyContext = _MyContext;
    }    公众诠释的getCount（）{
        返回persons.size（）;
    }    公共查看getView（INT位置，查看convertView，父母的ViewGroup）{
        视图V;
        如果（convertView == NULL）{
            LayoutInflater李= getLayoutInflater（）;
            V = li.inflate（R.layout.setting_gried_item，NULL）;
            TextView的电视=（TextView中）v.findViewById（R.id.grid_item_text）;
            tv.setText（档案+位置）;            tv.setText（persons.get（位置））;        }
        其他
        {
            V = convertView;
        }
        返回伏;
    }    公共对象的getItem（INT为arg0）{
        返回null;
    }
    众长getItemId（INT为arg0）{
        返回0;
    }    //我们的图像的引用
    私人整数[] = mThumbIds {
            R.drawable.one，R.drawable.two，
            R.drawable.five，R.drawable.four，
            R.drawable.eight，R.drawable.seven，
            R.drawable.seven
        };
    私有String [] =名称{
            墙纸设置，字体设置，
            Sysnchronization下载，上传Sysnchronization
            更改密码，照相机，
            画廊
    };
}
 

和您的XML就像是：

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT; LinearLayout中的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
机器人：ID =@ + ID /的GridItem
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
机器人：方向=垂直
机器人：重力=CENTER_HORIZONTAL
机器人：layout_x =201px
机器人：layout_y =165像素＆GT;
＆LT; TextView的机器人：ID =@ + ID / grid_item_text
  机器人：layout_width =WRAP_CONTENT
  机器人：layout_height =WRAP_CONTENT
  机器人：文字=TextView的
  机器人：重力=CENTER_HORIZONTAL
  机器人：文字颜色=＃000000＆GT;
＆LT; / TextView的＆GT;＆LT; / LinearLayout中＆GT;
 

这是Setting.xml的

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？; ＆LT; GridView控件的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
机器人：背景=@绘制/壁纸
机器人：ID =@ + ID / settinggridview
机器人：layout_width =FILL_PARENT
机器人：layout_height =FILL_PARENT
机器人：为numColumns =auto_fit
机器人：textFilterEnabled =真
机器人：stretchMode =columnWidth时
机器人：比重=中心
机器人：horizo​​ntalSpacing =15像素
机器人：verticalSpacing =25像素
＆GT;
 

试试这样

I've a collection of array list objects like:

ArrayList<Person> persons=new ArrayList<Person>();

so how can i bind this list of objects persons to android gridview?

解决方案

  GridView settingGrid;
  ArrayList<Person> persons;
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.setting);

   persons =new ArrayList<Person>();

    settingGrid = (GridView)findViewById(R.id.settinggridview);
    settingGrid.setAdapter(new SettingImageAdapter(this));
    settingGrid.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView parent, View v, int position,long id) {
             });

 public class SettingImageAdapter extends BaseAdapter{
    Context MyContext;

    public SettingImageAdapter(Context _MyContext){
        MyContext = _MyContext;
    }

    public int getCount() {
        return persons.size();
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        View v;
        if(convertView==null){
            LayoutInflater li = getLayoutInflater();
            v = li.inflate(R.layout.setting_gried_item, null);
            TextView tv = (TextView)v.findViewById(R.id.grid_item_text);
            tv.setText("Profile "+position);

            tv.setText(persons.get(position));

        }
        else
        {
            v = convertView;
        }
        return v;
    }

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


    public long getItemId(int arg0) {
        return 0;
    }

    // references to our images
    private Integer[] mThumbIds = { 
            R.drawable.one, R.drawable.two,
            R.drawable.five, R.drawable.four, 
            R.drawable.eight,R.drawable.seven,
            R.drawable.seven
        };
    private String[] names = {
            "Wallpaper Setting","Font Setting",
            "Sysnchronization Download","Sysnchronization Upload",
            "Change Password","Camera",
            "Gallery"
    };
}

And your XML like be :

   <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/GridItem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_x="201px"
android:layout_y="165px" >


<TextView android:id="@+id/grid_item_text"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="TextView"
  android:gravity="center_horizontal"
  android:textColor="#000000">
</TextView>

</LinearLayout>

This is setting.xml

  <?xml version="1.0" encoding="utf-8"?>

 <GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:background="@drawable/wallpaper"
android:id="@+id/settinggridview" 
android:layout_width="fill_parent"
android:layout_height="fill_parent" 
android:numColumns="auto_fit"
android:textFilterEnabled="true"
android:stretchMode="columnWidth" 
android:gravity="center"
android:horizontalSpacing="15px" 
android:verticalSpacing="25px"
>
