Android 官方下拉刷新SwipeRefreshLayout使用

网上的下拉刷新控件有很多，比如常用的PullToRefresh、XListView等，这篇文章我们来学习Android 官方的下拉刷新SwipeRefreshLayout。SwipeRefreshLayout是v4包中的，注意要把Support library的版本升级到19.1以上。下面我们来看下怎样实现。

一、布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.huang.loadimage.MainActivity">

    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipeRefreshLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

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

            <ImageView
                android:id="@+id/imageView"
                android:layout_width="match_parent"
                android:layout_height="300dp" />
        </ScrollView>
    </android.support.v4.widget.SwipeRefreshLayout>

</RelativeLayout>

二、主要代码

  swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
        //设置颜色
        swipeRefreshLayout
                .setColorSchemeResources(android.R.color.holo_red_light);
        //设置监听
        swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {

            public void onRefresh() {
                //将setRefreshing设置为true
                swipeRefreshLayout.setRefreshing(true);
            }
        });

停止刷新：

swipeRefreshLayout.setRefreshing(true);
