如何做聊天泡建设ConstraintLayout

Question

我有这样的Android XML布局，看起来像这样，当你看到它聊天气泡。我想把它从LinearLayout转换为ConstraintLayout
。
这是LinearLayout版本，它看起来不错

这是ConstraintLayout版和聊天bubbels看起来不那么好看。

我想一些帮助，这气泡。你看到的箭头很难约束，所以看起来不错。我添加了一个android.support.constraint.Guideline来做一些约束但不工作。

这里是ConstraintLayout XML

     app:layout_constraintHorizontal_bias="0.0" 
     android:layout_marginEnd="16dp"

    <ImageView

     app:layout_constraintRight_toRightOf="parent" 
     android:layout_marginRight="8dp" /> 

</android.support.constraint.ConstraintLayout> 

也许有在GitHub的一些库，创建这个气泡或任何想法将是巨大的？
