约束布局边距不断变化

Question

正如您在视频中看到的那样，左侧按钮的边距一直在变化，我希望它们不要改变。

我正在做一个计算器，我想在不改变边距的情况下将所有按钮移动到一起。

代码如下：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.a3ibm.calculator.MainActivity">


    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        app:layout_constraintBaseline_toBaselineOf="@+id/button2"
        app:layout_constraintRight_toLeftOf="@+id/button2"
        android:layout_marginRight="86dp" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintHorizontal_bias="0.864"
        app:layout_constraintVertical_bias="0.319" />
</android.support.constraint.ConstraintLayout>

这是您想要的可能解决方案。问题在于居中：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        app:layout_constraintEnd_toStartOf="@+id/button2"
        android:layout_marginEnd="56dp"
        android:layout_marginRight="56dp"
        app:layout_constraintTop_toTopOf="@+id/button2"
        app:layout_constraintBottom_toBottomOf="@+id/button2"
        app:layout_constraintVertical_bias="0.0" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        tools:layout_editor_absoluteY="186dp"
        tools:layout_editor_absoluteX="208dp" />
</android.support.constraint.ConstraintLayout>
