When adding a TextView using ConstraintSet#connect to an empty ConstraintLayout defined in XML, left and right margins are ignored (are zero) while top and bottom margins are honored. The TextView height and width are both set to "MATCH_CONSTRAINT". See the following code and screen shot. This works fine when everything is set in XML.

I expect each side of the TextView to have the specified margin set in ConstraintSet#connect.

Library used (support-v4, appcompat-v7, ...):
    com.android.support:appcompat-v7:25.3.1
    com.android.support.constraint:constraint-layout:1.0.2

Version used:

Theme used:
Theme.AppCompat.Light.DarkActionBar

Devices/Android versions reproduced on:
Emulator/API 24
Samsung S7/API 24

- Relevant code to trigger the issue.
public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ConstraintLayout layout;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        layout = (ConstraintLayout) findViewById(R.id.constraint_layout);
        TextView textView = new TextView(this);
        textView.setId(View.generateViewId());
        textView.setBackgroundColor(Color.RED);
        textView.setGravity(Gravity.CENTER);
        textView.setText("A text view");
        layout.addView(textView);

        ConstraintSet constraints = new ConstraintSet();
        constraints.clone(layout);
        constraints.constrainWidth(textView.getId(), ConstraintSet.MATCH_CONSTRAINT);
        constraints.constrainHeight(textView.getId(), ConstraintSet.MATCH_CONSTRAINT);
        constraints.connect(textView.getId(), ConstraintSet.LEFT, ConstraintSet.PARENT_ID,
                ConstraintSet.LEFT, 40);
        constraints.connect(textView.getId(), ConstraintSet.RIGHT, ConstraintSet.PARENT_ID,
                ConstraintSet.RIGHT, 40);
        constraints.connect(textView.getId(), ConstraintSet.TOP, ConstraintSet.PARENT_ID,
                ConstraintSet.TOP, 80);
        constraints.connect(textView.getId(), ConstraintSet.BOTTOM, ConstraintSet.PARENT_ID,
                ConstraintSet.BOTTOM, 80);
        constraints.applyTo(layout);
    }
