Android-contentprovider 获取手机联系人

                                 Android-contentprovider 获取手机联系人

一，布局文件（3个）

1，activity_main.xml



    
    


2，activity_test.xml


    
    
    
    
        
    
    


3，contact_list_item.xml


    
    
    
    
        
    
    

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
