为GrIDVIEw添加边框效果，供大家参考，具体内容如下

1.自定义GrIDVIEw的item样式：

grID_item.xml文件

<?xml version="1.0" enCoding="utf-8"?> <linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"   androID:layout_wIDth="wrap_content"   androID:layout_height="wrap_content" >   <ImageVIEw     androID:ID="@+ID/item_image"     androID:layout_wIDth="115dp"     androID:layout_height="115dp"     androID:padding="8dp"     androID:background="@drawable/grID_selector"      /> </linearLayout> 

2.设置GrIDVIEw item的背景：
grID_selector.xml文件

<?xml version="1.0" enCoding="utf-8"?> <selector xmlns:androID="http://schemas.androID.com/apk/res/androID">     <item androID:state_window_focused="false"      androID:drawable="@drawable/grID_normal" />    <item androID:state_selected="true"     androID:drawable="@drawable/grID_pressed" />      <item androID:state_pressed="true"     androID:drawable="@drawable/grID_pressed" /> </selector> 

3.设置GrIDVIEw的ListSelector为透明：

androID:ListSelector="@androID:color/transparent" 

4.自定义GrIDVIEw的adapter：

import java.util.ArrayList; import androID.content.Context; import androID.graphics.drawable.Drawable; import androID.vIEw.LayoutInflater; import androID.vIEw.VIEw; import androID.vIEw.VIEwGroup; import androID.Widget.BaseAdapter; import androID.Widget.ImageVIEw;  public class GrIDAdapter extends BaseAdapter {   private Context mContext = null;   private LayoutInflater inflater = null;   private ArrayList<Drawable> drawableList = null;    public GrIDAdapter(Context c) {     this.mContext = c;     this.inflater = LayoutInflater.from(mContext);   }   public voID setDataSource(ArrayList<Drawable> List){     this.drawableList = List;   }   public int getCount() {     if(drawableList != null){       return drawableList.size();     }else{       return 0;     }   }    public Object getItem(int position) {     return drawableList.get(position);   }    public long getItemID(int position) {     return position;   }    public VIEw getVIEw(int position,VIEw convertVIEw,VIEwGroup parent) {      ImageVIEw imageVIEw = new ImageVIEw(mContext);     if (convertVIEw == null) {       convertVIEw = inflater.inflate(R.layout.grID_item,null);       imageVIEw = (ImageVIEw) convertVIEw.findVIEwByID(R.ID.item_image);       imageVIEw.setScaleType(ImageVIEw.ScaleType.CENTER_INSIDE);       convertVIEw.setTag(imageVIEw);     } else {       imageVIEw = (ImageVIEw) convertVIEw.getTag();     }     imageVIEw.setimageDrawable(drawableList.get(position));     return convertVIEw;   } }
