我知道使用线性布局的解决方案。你能帮我使用约束布局吗? –

试试这个工作对我来说...

<android.support.constraint.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<Button 
    android:id="@+id/button_save" 
    android:layout_width="0dp" 
    android:layout_height="wrap_content" 
    android:text="@string/button_save_text" 
    android:layout_marginStart="8dp" 
    android:layout_marginBottom="8dp" 
    android:layout_marginEnd="4dp" 
    app:layout_constraintLeft_toLeftOf="parent" 
    app:layout_constraintBottom_toBottomOf="parent" 
    app:layout_constraintRight_toLeftOf="@+id/button_share" 
    app:layout_constraintHorizontal_chainStyle="spread" /> 

<Button 
    android:id="@+id/button_share" 
    android:layout_width="0dp" 
    android:layout_height="wrap_content" 
    android:text="@string/button_share_text" 
    android:layout_marginStart="4dp" 
    android:layout_marginEnd="8dp" 
    android:layout_marginBottom="8dp" 
    app:layout_constraintLeft_toRightOf="@+id/button_save" 
    app:layout_constraintRight_toLeftOf="parent" 
    app:layout_constraintBottom_toBottomOf="parent" /> 

</android.support.constraint.ConstraintLayout>

试试下面的代码

<?xml version="1.0" encoding="utf-8"?>

    app:layout_editor_absoluteX="0dp" 
    app:layout_editor_absoluteY="80dp" 
    tools:layout_editor_absoluteX="0dp" 
    tools:layout_editor_absoluteY="80dp"> 


    <Button 
     android:text="Button" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/button7"

     app:layout_constraintLeft_toLeftOf="parent" 
     tools:layout_constraintRight_creator="1" 
     tools:layout_constraintLeft_creator="1" /> 

    <Button

     android:layout_width="wrap_content"

     app:layout_constraintRight_toLeftOf="@+id/button7" 
     android:layout_marginEnd="8dp" /> 

    <Button
