attrs定义如下

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="ClockView">
        <attr name="pointer_color" format="color" />
        <attr name="scale_color" format="color" />
        <attr name="one_circle_color" format="color" />
        <attr name="two_circle_color" format="color" />
        <attr name="three_circle_color" format="color" />
        <attr name="four_circle_color" format="color" />
    </declare-styleable>
</resources>

自定义ClockView代码如下

package com.example.helloworld;

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.view.View;

import androidx.annotation.Nullable;

import java.util.Calendar;

public class ClockView extends View {
    private static final int DEFAULT_POINTER_COLOR = Color.parseColor("#FFFFFF");
    private static final int DEFAULT_SCALE_COLOR = Color.parseColor("#FFFFFF");
    private static final int DEFAULT_ONE_CIRCLE_COLOR = Color.parseColor("#FFFFFF");
    private static final int DEFAULT_TWO_CIRCLE_COLOR = Color.parseColor("#CCCCCC");
    private static final int DEFAULT_THREE_CIRCLE_COLOR = Color.parseColor("#BBBBBB");
    private static final int DEFAULT_FOUR_CIRCLE_COLOR = Color.parseColor("#AAAAAA");
    private static final int DEFAULT_FOUR_CIRCLE_DIAMETER = 180; // 默认外圈圆直径，也就是该控件默认宽高，单位dp

    private int pointerColor; // 指针颜色
    private int scaleColor; /
