Android 下拉刷新,非常强大的下拉刷新功能

Android下拉刷新各式各样,今天介绍两种常见的

第一种下拉刷新就是Android自带API ,V4包下面的

android.support.v4.widget.SwipeRefreshLayout

只要将要刷新的控件放到SwipeRefreshLayout 里面

比如:

<android.support.v4.widget.SwipeRefreshLayoutandroid:id="@+id/swipeRefreshLayout"android:layout_width="match_parent"android:layout_height="match_parent">    <android.support.v7.widget.RecyclerView        android:id="@+id/rv"        android:layout_width="match_parent"        android:layout_height="match_parent"></android.support.v7.widget.RecyclerView></android.support.v4.widget.SwipeRefreshLayout>

然后再代码里面

mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {    @Override    public void onRefresh() {        new Handler().postDelayed(new Runnable() {            @Override            public void run() {                List headDatas = new ArrayList<>();                for (int i = 30; i < 40; i++) {                    headDatas.add("Heard Item " + i);                }                mMyAdapter.AddHeaderItem(headDatas);                //刷新完成                mSwipeRefreshLayout.setRefreshing(false);                Toast.makeText(MainActivity.this, "更新了 " + headDatas.size() + " 条目数据", Toast.LENGTH_SHORT).show();            }        }, 3000);    }});

第二种介绍第三方的下拉刷新

首先

compile 'in.srain.cube:ultra-ptr:1.0.11'

应用一下

然后在布局文件.xml加上

<in.srain.cube.views.ptr.PtrClassicFrameLayout    xmlns:cube_ptr="http://schemas.android.com/apk/res-auto"    android:id="@+id/store_house_ptr_frame"    android:layout_width="match_parent"    android:layout_height="match_parent"    cube_ptr:ptr_duration_to_close="300"    cube_ptr:ptr_duration_to_close_header="800"    cube_ptr:ptr_keep_header_when_refresh="true"    cube_ptr:ptr_pull_to_fresh="false"    cube_ptr:ptr_ratio_of_header_height_to_refresh="1.2"    cube_ptr:ptr_resistance="1.7"></in.srain.cube.views.ptr.PtrClassicFrameLayout>

代码里面

mPtrClassicFrameLayout = (PtrClassicFrameLayout) findViewById(R.id.store_house_ptr_frame);

mPtrClassicFrameLayout.setPtrHandler(new PtrHandler() {    @Override    public void onRefreshBegin(PtrFrameLayout frame) {        frame.postDelayed(new Runnable() {            @Override            public void run() {                mPtrClassicFrameLayout.refreshComplete();                mPtrClassicFrameLayout.setLastUpdateTimeKey("2017-2-10");            }        }, 2000);    }    @Override    public boolean checkCanDoRefresh(PtrFrameLayout frame, View content, View header) {        return PtrDefaultHandler.checkContentCanBePulledDown(frame, content, header);    }});

既可以下拉刷新,还可以修改第三方,变成产品要求的背景样式.
