Android--读取通讯录并添加联系人

1.加入读写权限

联系人信息Uri：

content://com.android.contacts/contacts

联系人电话Uri：

content://com.android.contacts/data/phones

联系人Email Uri：

content://com.android.contacts/data/emails

（推荐）也可以这样获取联系人信息Uri：Uri uri = ContactsContract.Contacts.CONTENT_URI;

2.查询与添加联系人的操作（单元测试用例）

    public class ContactTest extends AndroidTestCase   
    {  
        private static final String TAG = "ContactTest";  
          
        /** 
         * 获取通讯录中所有联系人的简单信息 
         * @throws Throwable 
         */  
        public void testGetAllContact() throws Throwable  
        {  
            //获取联系人信息的Uri  
            Uri uri =  ContactsContract.Contacts.CONTENT_URI;  
            //获取ContentResolver  
            ContentResolver contentResolver = this.getContext().getContentResolver();  
            //查询数据，返回Cursor  
            Cursor cursor = contentResolver.query(uri, null, null, null, null);  
            while(cursor.moveToNext())  
            {  
                StringBuilder sb = new StringBuilder();  
                //获取联系人的ID  
                String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));    
                //获取联系人的姓名  
                String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));   
                //构造联系人信息  
                sb.append("contactId=").append(contactId).append(",Name=").append(name);  
                //查询电话类型的数据操作  
                Cursor phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,    
                        null,    
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,    
                        null, null);    
                while(phones.moveToNext())  
                {  
                    String phoneNumber = phones.getString(phones.getColumnIndex(  
                            ContactsContract.CommonDataKinds.Phone.NUMBER));  
                    //添加Phone的信息  
                    sb.append(",Phone=").append(phoneNumber);  
                }  
                phones.close();  
                  
                //查询Email类型的数据操作  
                Cursor emails = contentResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,    
                           null,    
                           ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,    
                           null, null);    
                while (emails.moveToNext())   
                {    
                    String emailAddress = emails.getString(emails.getColumnIndex(  
                            ContactsContract.CommonDataKinds.Email.DATA));  
                    //添加Email的信息  
                    sb.append(",Email=").append(emailAddress);  
                }   
                emails.close();  
                Log.i(TAG, sb.toString());
