Android 约束布局 ConstrainLayout min max width

写一个自定义view

package com.anguomob.guideline

import android.content.Context
import android.graphics.Canvas
import android.graphics.Color
import android.util.AttributeSet
import android.view.View

class ZeroView constructor(context: Context?, attrs: AttributeSet?, defStyleAttr: Int) :
    View(context, attrs, defStyleAttr) {
    override fun onDraw(canvas: Canvas?) {
        super.onDraw(canvas)
        canvas?.drawColor(Color.RED);
    }

}

放到布局当中

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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="match_parent"
    tools:context=".MainActivity">
