 private void deleteContactPhoneNumber(String contactName) { 

 //根据姓名求id

 Toast.makeText(this, "添加新的联系人：" + contactName + " " + phoneNumber, Toast.LENGTH_SHORT).show(); 

 private void queryContactPhoneNumber() { 

 String[] cols = {ContactsContract.PhoneLookup.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER}; 

 Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 

 cols, null, null, null); 

 for (int i = 0; i cursor.getCount(); i++) { 

 cursor.moveToPosition(i); 

 // 取得联系人名字 

 int nameFieldColumnIndex = cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME); 

 int numberFieldColumnIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); 

 String name = cursor.getString(nameFieldColumnIndex); 

 String number = cursor.getString(numberFieldColumnIndex); 

 Toast.makeText(this, name + " " + number, Toast.LENGTH_SHORT).show(); 

}

该活动主要是根据http://www.cnblogs.com/liaojie970/p/5744580.html这篇博客改编而来，将里面如：

Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");

方式改为了

uri = ContactsContract.Data.CONTENT_URI;

其基本思路是一样的
