Android联系人增删改查

1：申请权限

   <uses-permission android:name="android.permission.READ_CONTACTS"/>
    <uses-permission android:name="android.permission.WRITE_CONTACTS"/>

2：读取联系人

 Cursor cursor = context.getContentResolver()
                .query(ContactsContract.Contacts.CONTENT_URI,
                        null, null, null, null);
        if (cursor == null) {
            Log.e(TAG, "联系人cursor is null");
            return;
        }
        while (cursor.moveToNext()) {
            @SuppressLint("Range") int id = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts._ID));
            @SuppressLint("Range") String lastUpdatedTimeStamp = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.CONTACT_LAST_UPDATED_TIMESTAMP));
            @SuppressLint("Range") String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            Log.e(TAG, "id:" + id + "  name:" + name);
        }

3：删除联系人

    private void delContact2(Context c, String mContactId) {
        ArrayList ops = new ArrayList();
// 先删除子表Contacts中的数据
        ops.add(ContentProviderOperation
                .newDelete(ContactsContract.Contacts.CONTENT_URI)
                .withSelection(
                        ContactsContract.Contacts._ID + "=?",
                        new String[]{String.valueOf(mContactId)})
                .build());
// 然后删除子表Data中的数据
        ops.add(ContentProviderOperation
                .newDelete(ContactsContract.Data.CONTENT_URI)
                .withSelection(
                        ContactsContract.Data.RAW_CONTACT_ID + "=?",
                        new String[]{String.valueOf(mContactId)})
                .build());
// 最后删除父表RawContacts中的数据
        ops.add(ContentProviderOperation
                .newDelete(ContactsContract.RawContacts.CONTENT_URI)
                .withSelection(
                        ContactsContract.RawContacts.CONTACT_ID
                                + "=?",
                        new String[]{String.valueOf(mContactId)})
                .build());
        try {
            getContentResolver().applyBatch(
                    ContactsContract.AUTHORITY, ops);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
