TimeLine就像iOS Path app

Question

我想制作一个像这样的时间表

我试图制作它并且它适用于match_parent内容但是为了更少，这里没有底线是图片

这是我使用ConstraintLayout的XML代码，我使用match_constraint作为底线和顶行

<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:layout_width="match_parent"
android:layout_height="wrap_content">

<android.support.v7.widget.CardView
    android:id="@+id/card1"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginBottom="8dp"
    android:layout_marginEnd="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    android:background="@color/red"
    app:cardBackgroundColor="@color/white"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="0.0"
    app:layout_constraintStart_toEndOf="@+id/circleImageView"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="0.0">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:textSize="20sp"
        android:padding="15dp"
        android:id="@+id/tv"
        android:text="125125125"
        />
</android.support.v7.widget.CardView>

<View
    android:layout_width="0.6dp"
    android:layout_height="0dp"
    android:layout_marginEnd="8dp"
    android:layout_marginStart="8dp"
    android:background="#797979"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="@+id/circleImageView"
    app:layout_constraintStart_toStartOf="@+id/circleImageView"
    app:layout_constraintTop_toBottomOf="@+id/circleImageView" />

<ImageView
    android:id="@+id/circleImageView"
    android:layout_width="6dp"
    android:layout_height="6dp"

    android:layout_marginEnd="4dp"
    android:background="@drawable/circle_bg"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="0.01"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="0.06999999" />

<View
    android:layout_width="0.6dp"
    android:layout_height="0dp"
    android:layout_marginEnd="8dp"
    android:layout_marginStart="8dp"
    android:background="#797979"
    app:layout_constraintBottom_toTopOf="@+id/circleImageView"
    app:layout_constraintEnd_toEndOf="@+id/circleImageView"
    app:layout_constraintStart_toStartOf="@+id/circleImageView"
    app:layout_constraintTop_toTopOf="parent" />

任何人都可以帮我解决这个问题吗？我想在没有match_parent内容

的情况下绘制底线
