获取手机联系人姓名,电话

- 1,添加权限
    <!-- 获取通讯录权限 -->
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission  android:name="android.permission.CALL_PHONE"/>
    <uses-permission android:name="android.permission.WRITE_CONTACTS" />
- 2,代码,跳转
     Intent intent3 = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
                startActivityForResult(intent3, REQUEST_ADDPHONE);
- 3,获取得到的结果
      switch (requestCode) {
                case REQUEST_ADDPHONE:
                    if (resultCode == RESULT_OK) {
                        try {
                            //处理返回的data,获取选择的联系人信息
                            Uri contactData = data.getData();
                            Cursor cursor = getContentResolver().query(contactData, null, null, null, null);
                            cursor.moveToFirst();
                            String[] str_data = PhoneUtils.getContactPhone(cursor,this);

                            Log.d("date",str_data[0] + str_data[1]);
                            Toast.makeText(this, str_data[0] + str_data[1] ,Toast.LENGTH_SHORT).show();

                        } catch (Exception e) {
                            Toast.makeText(this, "获取联系人失败", Toast.LENGTH_SHORT).show();
                        }
                    }
                    break;
            }

- 4,工具类
    
    public class PhoneUtils {
         public static String[] getContactPhone(Cursor cursor, Context context) {
        int phoneColumn = cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
        int phoneNum = cursor.getInt(phoneColumn);
        String[] str = new String[2];
        String username = "";
        String result = "";
        if (phoneNum > 0) {
            // 获得联系人的ID号
            int idColumn = cursor.getColumnIndex(ContactsContract.Contacts._ID);
            String contactId = cursor.getString(idColumn);
            // 获得联系人电话的cursor
            Cursor phone = context.getContentResolver().query(
                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId, null, null);
            if (phone.moveToFirst()) {
                for (; !phone.isAfterLast(); phone.moveToNext()) {
                    int index = phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
                    String phoneNumber = phone.getString(index);
                    str[0] = phoneNumber;
                    username = getContactNameFromPhoneBook(context, phoneNumber);
                    str[1] = username;
                }
                if (!phone.isClosed()) {
                    phone.close();
                }
            }
        }
        return str;
    }


     public static  String getContactNameFromPhoneBook(Context context, String phoneNum) {
        String contactName = "";
        ContentResolver cr = context.getContentResolver();
        Cursor pCur = cr.query(
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                ContactsContract.CommonDataKinds.Phone.NUMBER + " = ?",
                new String[]{phoneNum}, null);
        if (pCur.moveToFirst()) {
            contactName = pCur
                    .getString(pCur
                            .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            pCur.close();
        }
        return contactName;
    }
