ConstraintLayout使用简单记录

1.首先引入对应的包
compile 'com.android.support.constraint:constraint-layout:1.0.2'
2.记录一下对应用的属性

layout_constraintLeft_toRightOf
layout_constraintRight_toLeftOf
layout_constraintRight_toRightOf
layout_constraintTop_toTopOf
layout_constraintTop_toBottomOf
layout_constraintBottom_toTopOf
layout_constraintBottom_toBottomOf

# 即文章的baseline对齐
layout_constraintBaseline_toBaselineOf

# 与left,right类似
layout_constraintStart_toEndOf 
layout_constraintStart_toStartOf
layout_constraintEnd_toStartOf
layout_constraintEnd_toEndOf

# margin不需要解释
android:layout_marginStart
android:layout_marginEnd
android:layout_marginLeft
android:layout_marginTop
android:layout_marginRight
android:layout_marginBottom

layout_constraintHorizontal_bias  
layout_constraintVertical_bias  

layout_constraintHorizontal_chainStyle
layout_constraintVertical_chainStyle

layout_constraintVertical_weight

Guideline 

3.贴一下简单的代码

贴一下效果图

另外其实是可以用拖拽的方式来实现的，具体可以参考郭神，鸿神的文章有具体的介绍：
