Android 下拉刷新 SwipeRefreshLayout 的Kotlin实现

原文链接https://www.shanya.world/archives/614f32fd.html

添加依赖

implementation 'androidx.swiperefreshlayout:swiperefreshlayout:1.0.0'

xml替换上SwipeRefreshLayout

放上一个TextView做刷新演示

<?xml version="1.0" encoding="utf-8"?>
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout 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:id="@+id/swipeRedreshLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal|center_vertical"
        android:text="TextView"
        android:textSize="30sp" />
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

效果图

在这里插入图片描述

MainActivity 代码

package com.shanya.swiperefreshdemo

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import kotlinx.android.synthetic.main.activity_main.*
import java.util.*

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        swipeRedreshLayout.setOnRefreshListener {
            textView.text = System.currentTimeMillis().toString()
            swipeRedreshLayout.isRefreshing = false
        }
    }
}
