Position view outside of ConstraintLayout

This appears to be an issue with ConstraintLayout 1.1.0-beta1; It works as expected in ConstraintLayout 1.1.0-beta3.

Update to ConstraintLayout 1.1.0-beta3. I will also note that you need to constrain your view horizontally by doing something like the following.

<View
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:background="@color/colorPrimary"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintBottom_toTopOf="parent" />

On a side note, negative margins are not accepted in ConstraintLayout. See this Stack Overflow question regarding negative margins and ConstraintLayout.

I got another way to solve the problem:

1.Add a anchor(anchor_left) layout_constraintStart_toStartOf="parent".

2.Add YourView layout_constraintEnd_toStartOf="@+id/anchor_left"

That's it!

code:

<android.support.constraint.ConstraintLayout>
    <View
        android:id="@+id/anchor_left"
        app:layout_constraintStart_toStartOf="parent"/>

    <YourView
        android:id="@+id/ll_left"
        app:layout_constraintEnd_toStartOf="@+id/anchor_left"/>
</android.support.constraint.ConstraintLayout>
