Step 1. Add the JitPack repository to your build file
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
compile 'com.github.yanjiabin:DDPullToRefresh-master:v1.0'
}
in your xml
<?xml version="1.0" encoding="utf-8"?>
<com.yanjiubin.pulltorefreshlibrary.RefreshLayout
android:id="@+id/refresh_layout"
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">
<!-- 當然這裏我使用的是recyecleview -->
<android.support.v7.widget.RecyclerView
android:id="@+id/recycleview"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</com.yanjiubin.pulltorefreshlibrary.RefreshLayout>
in your code
refreshLayout = (RefreshLayout) findViewById(R.id.refresh_layout);
mRecyclerView = (RecyclerView) findViewById(R.id.recycleview);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mRecyclerView.setNestedScrollingEnabled(false);
mAdapter = new TextAdapter();
mRecyclerView.setAdapter(mAdapter);
//美團的效果就是new MeiTuanSelfHeaderViewManager(this),基本的下拉效果new NormalSelfHeaderViewManager(this)
refreshLayout.setSelfHeaderViewManager(new MeiTuanSelfHeaderViewManager(this));
pageLimitDelegate.attach(refreshLayout, mRecyclerView, mAdapter); //pageLimitDelegate 這個是一個分頁管理類
需要注意的是
這裏的上拉加載我使用的是 BaseRecyclerViewAdapterHelper 這個庫,個人感覺挺不錯的,我開發的項目中也都是用的這個庫,挺實用的,推薦給大家.
recycleView 搭配BaseRecyclerViewAdapterHelper可以基本上可以解決所有的列表展示.下拉刷新的和上拉加載的邏輯都封裝在了pageLimitDelegate這個分頁管理類中, 我們只需要請求數據的類 implements PageLimitDelegate.DataProvider 就行了 然後在重寫的 loadData(int page) 中去請求數據.
