二，建实体类，
public class ContactBean {   private int contactId;   private String desplayName;   private String phoneNum;   private String sortKey;   private Long photoId;   private String lookUpKey;   private int selected = 0;   private String formattedNumber;   private String pinyin;   public int getContactId() {      return contactId;   }   public void setContactId(int contactId) {      this.contactId = contactId;   }   public String getDesplayName() {      return desplayName;   }   public void setDesplayName(String desplayName) {      this.desplayName = desplayName;   }   public String getPhoneNum() {      return phoneNum;   }   public void setPhoneNum(String phoneNum) {      this.phoneNum = phoneNum;   }   public String getSortKey() {      return sortKey;   }   public void setSortKey(String sortKey) {      this.sortKey = sortKey;   }   public Long getPhotoId() {      return photoId;   }   public void setPhotoId(Long photoId) {      this.photoId = photoId;   }   public String getLookUpKey() {      return lookUpKey;   }   public void setLookUpKey(String lookUpKey) {      this.lookUpKey = lookUpKey;   }   public int getSelected() {      return selected;   }   public void setSelected(int selected) {      this.selected = selected;   }   public String getFormattedNumber() {      return formattedNumber;   }   public void setFormattedNumber(String formattedNumber) {      this.formattedNumber = formattedNumber;   }   public String getPinyin() {      return pinyin;   }   public void setPinyin(String pinyin) {      this.pinyin = pinyin;   }}
三，写具體代码
