Android通用可自定义下拉刷新上拉加载组件PopularRefreshLayout

简述

目前流行android 下拉刷新上拉加载开源框架有很多，XListView,PullToRefresh,android-Ultra-Pull-To-Refresh 等，但是能够像android-Ultra-Pull-To-Refresh那样，将上下拉处理事件分装到一个类处理，并且提供自定义上下拉显示效果的开源组件不多。所以，小编初试，封装一个兼容性不错，而且可以自定义上下拉效果的组件popularrefreshlayout，

支持gradle引用 compile 'com.awarmisland.android:popularrefreshlayout:1.0.6'

功能简述

目前，小编设置两种下拉刷新效果，一种是经典默认下拉刷新效果，一种是Material风格的，如效果图所示。经过调试，PopularRefreshLayout支持ScrollView ,ListView,WebView等。

使用方式

1. gradle.build中添加引用 compile 'com.awarmisland.android:popularrefreshlayout:1.0.4'

2. 将需要下拉刷新的内容外面添加组件

 <com.awarmisland.android.popularrefreshlayout.RefreshLayout
        android:id="@+id/refresh"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
	
<com.awarmisland.android.popularrefreshlayout.RefreshLayout />

3.设置下拉刷新，上拉加载监听（以默认下拉刷新效果内嵌ListView为例子）

  RefreshLayout  refresh  = (RefreshLayout) findViewById(R.id.refresh);
  refresh.setAllowLoadMore(true);//设置支持上拉加载
  refresh.setRefreshListener(refreshListener);

private RefreshListener refreshListener = new RefreshListener() {
        @Override
        public void onRefresh(final RefreshLayout refreshLayout) {
            refreshLayout.postDelayed(new Runnable() {
                @Override
                public void run() {
                    refreshLayout.finishRefresh();
                    adapter.clear();
		    //刷新数据
                     
                    adapter.notifyDataSetChanged();
                }
            }, 3000);
        }

        @Override
        public void onRefreshLoadMore(final RefreshLayout refreshLayout) {
            refreshLayout.postDelayed(new Runnable() {
                @Override
                public void run() {
                    refreshLayout.finishRefreshLoadMore();
                    //添加数据
                }
            }, 3000);
        }
    };

4.自定义下拉上拉效果，通过自定义类继承BaseHeader 和BaseFooter，提供上下拉手势过程onBegin——>onPull ——>onRelease——>onRefreshing——>onComlete

    public abstract void onComlete(RefreshLayout materialRefreshLayout);
    public abstract void onBegin(RefreshLayout materialRefreshLayout);
    public abstract void onPull(RefreshLayout materialRefreshLayout, float fraction);
    public abstract void onRelease(RefreshLayout materialRefreshLayout, float fraction);
    public abstract void onRefreshing(RefreshLayout materialRefreshLayout);

5.以Material风格下拉刷新效果为例，添加自定义刷新效果

RefreshLayout   refresh  = (RefreshLayout) findViewById(R.id.refresh);
MaterialHeaderView headerView = new MaterialHeaderView(this);//初始化自定义刷新头部
refresh.setHeaderView(headerView);//添加头部
refresh.setAllowLoadMore(true);
