使用DataBinding自定义控件

使用DataBinding自定义控件：

1、view_time_type.xml

<?xml version="1.0" encoding="utf-8"?>
<layout>

    <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <com.caowj.enetcloud.view.widget.RadiusTextView
            android:id="@+id/rtv_week"
            style="@style/type_selected"
            android:text="@string/type_week"
            app:layout_constraintEnd_toStartOf="@+id/rtv_month"
            app:layout_constraintHorizontal_chainStyle="spread_inside"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

        <com.caowj.enetcloud.view.widget.RadiusTextView
            android:id="@+id/rtv_month"
            style="@style/type_unselected"
            android:text="@string/type_month"
            app:layout_constraintEnd_toStartOf="@+id/rtv_quarter"
            app:layout_constraintStart_toEndOf="@+id/rtv_week"
            app:layout_constraintTop_toTopOf="@+id/rtv_week" />

        <com.caowj.enetcloud.view.widget.RadiusTextView
            android:id="@+id/rtv_quarter"
            style="@style/type_unselected"
            android:text="@string/type_quarter"
            app:layout_constraintEnd_toStartOf="@+id/rtv_year"
            app:layout_constraintStart_toEndOf="@+id/rtv_month"
            app:layout_constraintTop_toTopOf="@+id/rtv_month" />

        <com.caowj.enetcloud.view.widget.RadiusTextView
            android:id="@+id/rtv_year"
            style="@style/type_unselected"
            android:text="@string/type_year"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toEndOf="@+id/rtv_quarter"
            app:layout_constraintTop_toTopOf="@+id/rtv_quarter" />
    </androidx.constraintlayout.widget.ConstraintLayout>
</layout>

2、TimeTypeView.kt

package com.caowj.enetcloud.view.widget

import android.content.Context
import android.util.AttributeSet
import android.view.LayoutInflater
import androidx.constraintlayout.widget.ConstraintLayout
import androidx.databinding.DataBindingUtil

    private fun initBinding() {
        val inflater: LayoutInflater =

    }

    private fun initListener() {
        _binding.rtvWeek.setOnClickListener {

            setSelectedItem(_binding.rtvWeek)

        }
        _binding.rtvMonth.setOnClickListener {

        }
    }

    private fun initDate() {

        _binding.rtvYear.setViewSelected(false)
    }

    private fun setSelectedItem(radiusTextView: RadiusTextView) {
        radiusTextView.setViewSelected(true)
    }

    fun setOnClick(
        weekListener: () -> Unit,
        monthListener: () -> Unit,
        quarterListener: () -> Unit,
        yearListener: () -> Unit
    ) {
        this.onWeekViewClick = weekListener
        this.onMonthViewClick = monthListener
        this.onQuarterViewClick = quarterListener
        this.onYearViewClick = yearListener
    }

    fun setOnWeekViewClick(weekListener: () -> Unit): TimeTypeView {
        this.onWeekViewClick = weekListener
        return this
    }

    fun setOnMonthViewClick(monthListener: () -> Unit): TimeTypeView {
        this.onMonthViewClick = monthListener
        return this
    }

    fun setOnQuarterViewClick(quarterListener: () -> Unit): TimeTypeView {
