如何保存联系人

 这两天项目有个需求，可以对事务操作人进行 【新建联系人】【保存到已有联系人】【编辑联系人(xxx)】.

 总结一下，日后备用。先看一下效果：

                                                                               

  一、【新建联系人】主要是给系统发一个Intent

            

 public void addContact() {
  Intent intent = new Intent("android.intent.action.INSERT",
    People.CONTENT_URI);
  if (emailAdderss != null) { // 将要增加的联系人信息放到 exta data里
     intent.putExtra(ContactsContract.Intents.Insert.EMAIL, emailAdderss);
     intent.putExtra(ContactsContract.Intents.Insert.NAME, creatorName);
  }
  startActivity(intent);
  setResult(RESULT_FIRST_USER);
  finish();

 }

二、【保存到已有联系人】.（备注：选联系人中之后，到编辑该联系人，程序手动需要继续调用系统功能）

     1、先调用系统的已有联系人列表

               Intent intent = new Intent("android.intent.action.PICK",
                  People.CONTENT_URI);
     2、设置resultCode             startActivityForResult(intent,Constants.PICK_CONTACT);

     3、编写响应 resultCode 代码，做出编辑响应。

          @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

switch (requestCode) {
   case Constants.PICK_CONTACT:
   if (resultCode == RESULT_OK) {
     Uri contactData = data.getData();  
     String urlStr = contactData.getEncodedPath();
    String[] idStrs = urlStr.split("/");
    int id = Integer.parseInt(idStrs[2]); // 主要是获得 选中人的 id 然后 进行编辑

     if (Build.VERSION.SDK_INT == 4 || Build.VERSION.RELEASE.equals("1.6")) { // 发送编辑联系人请求
      
      // for sdk1.6
      Intent intent_ = new Intent("android.intent.action.EDIT", Uri.parse("content://contacts/people/" + id));
      intent_.putExtra(ContactsContract.Intents.Insert.EMAIL, emailAdderss);
      startActivity(intent_);

     } else {
      Intent intent_ = new Intent("android.intent.action.EDIT", Uri.parse("content://com.android.contacts/raw_contacts/" + id));
      intent_.putExtra(ContactsContract.Intents.Insert.EMAIL, emailAdderss);

      startActivity(intent_);
     }
     finish();
   }
   break;
  default:
   super.onActivityResult(requestCode, resultCode, data);
   break;
  }

三：编辑以后联系人

      1、根据email获得联系人名称

           public  String lookupContactNameByEmail(String email) {
  
  String where=Email.DATA1+"=?";
  Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, new String[]{ Email.CONTACT_ID}, where, new String[]{email}, null);
  if(cursor.moveToNext()){
   String contactWhere=Contacts._ID+"="+cursor.getInt(0);
   cursor.close();
   Cursor cursor2 = getContentResolver().query(Contacts.CONTENT_URI, new String[]{Contacts.DISPLAY_NAME}, contactWhere, null,null);
   if(cursor2.moveToNext()){
    String str = cursor2.getString(0);
    return str;
   }
  }
  return "unKnow";
 }

      2、发送编辑Action

      

 public void editContact() {
  Integer id = null;
  Cursor cursor = getContactsByEmail();
     if(cursor.getCount()>0){
      cursor.moveToFirst();
      id = cursor.getInt(cursor.getColumnIndex(Data.RAW_CONTACT_ID));
      DebugUtils.v(TAG, emailAdderss+"===================================================+++"+id );
   cursor.close();
   if (Build.VERSION.SDK_INT == 4 || Build.VERSION.RELEASE.equals("1.6")) {
    
    // for sdk1.6
    Intent intent_ = new Intent("android.intent.action.EDIT", Uri.parse("content://contacts/people/" + id));

    startActivity(intent_);

   } else {
    Intent intent_ = new Intent("android.intent.action.EDIT", Uri.parse("content://com.android.contacts/raw_contacts/" + id));
    startActivity(intent_);
   }
   
   finish();
     }
    
    
 }
