android - 联系人 API 编辑群组

Question

我正在尝试编辑组标题和注释，

编辑标题适用于系统组 和用户创建的组，

虽然注释列只有在系统组(例如“联系人”、“ friend ”、“家庭”、“同事”)时才会保留，我假设它不会为用户创建的组保存注释，或者某些如何被注释列中的标题列内容覆盖。 p>

如何在联系人组中使用备注栏？还有其他方法可以与组一起存储附加信息吗？这是我的代码 fragment :

     ArrayList<ContentProviderOperation> ops =new ArrayList<ContentProviderOperation>();

                ContentProviderOperation.Builder op = 
     ContentProviderOperation.newUpdate(ContactsContract.Groups.CONTENT_URI)
                    .withSelection(ContactsContract.Groups._ID + "="+group.getId(), null)
                    .withValue(ContactsContract.Groups.TITLE, group.getTitle());

                HashMap<String, String> notes = group.getNotes();
                if(notes!=null && notes.size()>0){
                    op = op.withValue(ContactsContract.Groups.NOTES, new Gson().toJson(group.getNotes()));
                }

                ops.add(op.build());
                try {
                    getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
                } catch (RemoteException e) {
                    e.printStackTrace();
                } catch (OperationApplicationException e) {
                    e.printStackTrace();
                }

希望这个解决方案对你有用，似乎对我也有用。

我用过 ContentResolver.update()方法。

I assume that it either doesn't save notes for user created groups or some how gets overwritten with title column content in notes column.

我能够使用以下代码更新用户创建的组的注释。

How can I use notes column in contact groups?

您可以使用注释列来保存任何 TEXT 值，因为它在 sqlite 中定义为 TEXT 类型。参见 ContactsContract.Groups.NOTES .

(在 Google Pixel XL、Oreo 8.0.0 上测试)

    public class MainActivity extends AppCompatActivity {

    private Cursor mCursor;
    private SimpleCursorAdapter adapter;
    private ListView lvGroups;

    @Override
    protected void onDestroy() {
        if (mCursor != null)
            mCursor.close();
        super.onDestroy();
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        lvGroups = findViewById(R.id.lvGroups);
        checkAndRequestPermission();

    }

    private void checkAndRequestPermission() {
        if (PermissionChecker.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) == PermissionChecker.PERMISSION_GRANTED) {
            loadGroups();
        } else {
            ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS}, 123);

        boolean isGranted = true;
        for (int i = 0; i < grantResults.length; i++) {
            if (grantResults[i] == PermissionChecker.PERMISSION_DENIED)
                isGranted = false;
        }
        if (isGranted)
            loadGroups();
        else
            ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS},123);
    }

    private void loadGroups() {
        mCursor = getContentResolver().query(ContactsContract.Groups.CONTENT_URI,null,ContactsContract.Groups.GROUP_IS_READ_ONLY + " = 0",null, ContactsContract.Groups.TITLE);

        adapter = new SimpleCursorAdapter(this, R.layout.contact_group_item, mCursor, new String[] {

        lvGroups.setAdapter(adapter);

        lvGroups.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Cursor cursor = adapter.getCursor();
                cursor.moveToPosition(position);

                int groupId = cursor.getInt(cursor.getColumnIndex(ContactsContract.Groups._ID));
                ContentValues contentValues = new ContentValues();
                contentValues.put(ContactsContract.Groups.NOTES,"My test Notes");
                getContentResolver().update(ContactsContract.Groups.CONTENT_URI, contentValues, ContactsContract.Groups._ID + " = " + groupId, null);
                adapter.notifyDataSetChanged();
            }
        });

    }
