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();
      }
      
      
  }
