RecyclerView曾經出來良久了，許很多多的項目都開端從ListView轉戰RecyclerView，那末，上拉加載和下拉刷新是一件很有需要的工作。

在ListView上，我們可以經由過程本身添加addHeadView和addFootView去添加頭結構和底部局完成自界說的上拉和下拉，或許應用一些第三方庫來簡略的集成，例如Android-pulltorefresh或許android-Ultra-Pull-to-Refresh，後者的自界說更強，但須要本身完成上拉加載。

而鄙人面我們將用兩種方法來完成上拉加載和下拉刷新

第一種方法：SwipeRefreshLayout+滑動底部主動加載

第二種方法：應用第三方庫SwipeToLoadLayout完成上拉加載和下拉刷新。

第一種方法：SwipeRefreshLayout+滑動底部主動加載

SwipeRefreshLayout完成很簡略，重點是滑動究竟部主動加載應當若何完成，其實其完成的方法相似於ListView的完成方法。

看一下activity_recycle_swiperefresh.xml文件：

<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/swipe_refresh"
 android:orientation="vertical" android:layout_width="match_parent"
 android:layout_height="match_parent">

 <android.support.v7.widget.RecyclerView
  android:id="@+id/swipe_target"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:scrollbars="none" />

</android.support.v4.widget.SwipeRefreshLayout>

結構文件就兩個控件，SwipeRefreshLayout中嵌套RecyclerView。

在代碼中初始化RecyclerView和完成adapter等，這不是重點，不再貼代碼。

在RecyclerView中無方法addOnScrollListener，該辦法相似於ListView的setOnScrollListener辦法，OnScrollListener中有兩個辦法的回調

*onScrolled(RecyclerView recyclerView, int dx, int dy) ：轉動的回調，dx和dy表現手指滑動程度和垂直的偏移量。

*onScrollStateChanged(RecyclerView recyclerView, int newState)：滑動狀況的回調。

那末，我們的側重點就在這個兩個辦法上了。

關於向上加載更多，我們須要有以下斷定

--能否是向上滑動

--能否滑動究竟部

--以後能否正在加載數據

--以後狀況能否是滑動停滯的狀況

完成比擬龐雜，界說一個類LoadDataScrollController，繼續類RecyclerView.OnScrollListener，

由於onScrollStateChanged其實狀況轉變時的回調，沒法不時的獲得顯示的條目和地位，所以我們在onScrolled中獲得響應地位，

 @Override
 public void onScrolled(RecyclerView recyclerView, int dx, int dy) {

  /**
   * 獲得結構參數
   */
  RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();

  //假如為null，第一次運轉，肯定結構類型
  if (mLayoutManagerType == null) {
   if (layoutManager instanceof LinearLayoutManager) {
    mLayoutManagerType = LayoutManagerType.LINEAR_LAYOUT;
   } else if (layoutManager instanceof GridLayoutManager) {
    mLayoutManagerType = LayoutManagerType.GRID_LAYOUT;
   } else if (layoutManager instanceof StaggeredGridLayoutManager) {
    mLayoutManagerType = LayoutManagerType.STAGGERED_GRID_LAYOUT;
   } else {
    throw new RuntimeException("LayoutManager should be LinearLayoutManager,GridLayoutManager,StaggeredGridLayoutManager");
   }
  }

  //關於不太可以或許的結構參數，分歧的辦法獲得到以後顯示的最初一個條目數
  switch (mLayoutManagerType) {
   case LINEAR_LAYOUT:
    mLastVisibleItemPosition = ((LinearLayoutManager) layoutManager).findLastVisibleItemPosition();
    break;
   case GRID_LAYOUT:
    mLastVisibleItemPosition = ((GridLayoutManager) layoutManager).findLastVisibleItemPosition();
    break;
   case STAGGERED_GRID_LAYOUT:
    StaggeredGridLayoutManager staggeredGridLayoutManager = (StaggeredGridLayoutManager) layoutManager;
    if (mLastPostions == null) {
     mLastPostions = new int[staggeredGridLayoutManager.getSpanCount()];
    }
    staggeredGridLayoutManager.findLastVisibleItemPositions(mLastPostions);
    mLastVisibleItemPosition = findMax(mLastPostions);
    break;
   default:
    break;
  }

 }

起首獲得結構治理器，並斷定是那品種型的，由於有三品種型，界說列舉來保留結構類型的參數

/**
 *
 * RecycleView的結構治理器的類型
 * Created by Alex_MaHao on 2016/5/10.
 */
public enum LayoutManagerType {
 LINEAR_LAYOUT,
 GRID_LAYOUT,
 STAGGERED_GRID_LAYOUT
}

然後依據結構通例其的類型獲得其以後顯示的最年夜條目，關於瀑布流來講，他假如是垂直的兩列瀑布的話，我們須要獲得兩列平分別最年夜條目數，停止比擬，選出最年夜條目數。

 /**
  * 當是瀑布流時，獲得到的是每個瀑布最下方顯示的條目，經由過程條目停止比較
  */
 private int findMax(int[] lastPositions) {
  int max = lastPositions[0];
  for (int value : lastPositions) {
   if (value > max) {
    max = value;
   }
  }
  return max;
 }

拿到以後最年夜的條目數以後，在onScrollStateChange中停止斷定狀況等，

 @Override
 public void onScrollStateChanged(RecyclerView recyclerView, int newState) {

  RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();

  //RecycleView 顯示的條目數
  int visibleCount = layoutManager.getChildCount();

  //顯示數據總數
  int totalCount = layoutManager.getItemCount();


  // 四個前提，分離是能否稀有據，狀況能否是滑動停滯狀況，顯示的最年夜條目能否年夜於全部數據（留意偏移量），能否正在加載數據
  if(visibleCount>0
    &&newState==RecyclerView.SCROLL_STATE_IDLE
    &&mLastVisibleItemPosition>=totalCount-1
    &&!isLoadData){
   //可以加載數據
   isLoadData = true;
  }

 }

正文很清晰，在加載數據的處所，我們將isLoadData設為true，同時應用接口回調加載數據，等數據加載完成，經由過程setLoadDataStatus辦法設置為false

 public void setLoadDataStatus(boolean isLoadData){
  this.isLoadData = isLoadData;
 }

假如如許就停止了，感到很費事，關於刷新和加載更多，我們須要在挪用的處所分離設置監聽，那末我們可讓LoadDataScrollController完成SwipeRefreshLayout的刷新監聽辦法，在應用我們界說的同一的上拉刷新和加載數據接口停止處置

/**
 * 完成上拉加載的監聽：加載前提：滑動到最初，且是停滯狀況，則開端加載數據
 * Created by Alex_MaHao on 2016/5/10.
 */
public class LoadDataScrollController extends RecyclerView.OnScrollListener implements SwipeRefreshLayout.OnRefreshListener {

 /**
  * 以後結構治理器的類型
  */
 private LayoutManagerType mLayoutManagerType;


 /**
  * 以後RecycleView顯示的最年夜條目
  */
 private int mLastVisibleItemPosition;


 /**
  * 每列的最初一個條目
  */
 private int[] mLastPostions;


 /**
  * 能否正在加載數據 包含刷新和向上加載更多
  */
 private boolean isLoadData = false;


 /**
  * 回調接口
  */
 private OnRecycleRefreshListener mListener;


 public LoadDataScrollController(OnRecycleRefreshListener onRecycleRefreshListener) {
  this.mListener = onRecycleRefreshListener;
 }

 @Override
 public void onScrolled(RecyclerView recyclerView, int dx, int dy) {

  /**
   * 獲得結構參數
   */
  RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();

  //假如為null，第一次運轉，肯定結構類型
  if (mLayoutManagerType == null) {
   if (layoutManager instanceof LinearLayoutManager) {
    mLayoutManagerType = LayoutManagerType.LINEAR_LAYOUT;
   } else if (layoutManager instanceof GridLayoutManager) {
    mLayoutManagerType = LayoutManagerType.GRID_LAYOUT;
   } else if (layoutManager instanceof StaggeredGridLayoutManager) {
    mLayoutManagerType = LayoutManagerType.STAGGERED_GRID_LAYOUT;
   } else {
    throw new RuntimeException("LayoutManager should be LinearLayoutManager,GridLayoutManager,StaggeredGridLayoutManager");
   }
  }

  //關於不太可以或許的結構參數，分歧的辦法獲得到以後顯示的最初一個條目數
  switch (mLayoutManagerType) {
   case LINEAR_LAYOUT:
    mLastVisibleItemPosition = ((LinearLayoutManager) layoutManager).findLastVisibleItemPosition();
    break;
   case GRID_LAYOUT:
    mLastVisibleItemPosition = ((GridLayoutManager) layoutManager).findLastVisibleItemPosition();
    break;
   case STAGGERED_GRID_LAYOUT:
    StaggeredGridLayoutManager staggeredGridLayoutManager = (StaggeredGridLayoutManager) layoutManager;
    if (mLastPostions == null) {
     mLastPostions = new int[staggeredGridLayoutManager.getSpanCount()];
    }
    staggeredGridLayoutManager.findLastVisibleItemPositions(mLastPostions);
    mLastVisibleItemPosition = findMax(mLastPostions);
    break;
   default:
    break;
  }

 }

 @Override
 public void onScrollStateChanged(RecyclerView recyclerView, int newState) {

  RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();

  //RecycleView 顯示的條目數
  int visibleCount = layoutManager.getChildCount();

  //顯示數據總數
  int totalCount = layoutManager.getItemCount();


  // 四個前提，分離是能否稀有據，狀況能否是滑動停滯狀況，顯示的最年夜條目能否年夜於全部數據（留意偏移量），能否正在加載數據
  if(visibleCount>0
    &&newState==RecyclerView.SCROLL_STATE_IDLE
    &&mLastVisibleItemPosition>=totalCount-1
    &&!isLoadData){
   //可以加載數據
   if(mListener!=null){
    isLoadData = true;
    mListener.loadMore();
   }
  }

 }


 /**
  * 當是瀑布流時，獲得到的是每個瀑布最下方顯示的條目，經由過程條目停止比較
  */
 private int findMax(int[] lastPositions) {
  int max = lastPositions[0];
  for (int value : lastPositions) {
   if (value > max) {
    max = value;
   }
  }
  return max;
 }


 public void setLoadDataStatus(boolean isLoadData){
  this.isLoadData = isLoadData;
 }

 @Override
 public void onRefresh() {
  //刷新數據的辦法
  if(mListener!=null){
   isLoadData = true;
   mListener.refresh();
  }

 }

 /**
  * 數據加載接口回調
  */
 interface OnRecycleRefreshListener{
  void refresh();
  void loadMore();
 }
}

最初看一下main的代碼

/**
 * 應用原生的SwipeRefreshLayout和代碼斷定

 *
 * Created by Alex_MaHao on 2016/5/10.
 */
public class SwipeRefreshActivity extends AppCompatActivity implements LoadDataScrollController.OnRecycleRefreshListener {


 private SwipeRefreshLayout mSwipeRefresh;

 private RecyclerView mRecycle;

 private HomeAdapter mAdapter;

 private LoadDataScrollController mController;


 private ProgressDialog pd;

 @Override
 protected void onCreate(@Nullable Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_recycle_swiperefresh);

  mRecycle = ((RecyclerView) findViewById(R.id.swipe_target));

  mSwipeRefresh = ((SwipeRefreshLayout) findViewById(R.id.swipe_refresh));

  mSwipeRefresh.setColorSchemeColors(Color.RED,Color.GREEN,Color.BLUE);

  /**
   * 創立掌握器，同時使以後activity完成數據監聽回調接口
   */
  mController = new LoadDataScrollController(this);



  mAdapter = new HomeAdapter();

  //設置垂直的線性結構治理器，Orientation --> VERTICAL:垂直 HORIZONTAL:程度
  LinearLayoutManager layoutManager = new LinearLayoutManager(this);
  layoutManager.setOrientation(LinearLayoutManager.VERTICAL);

  //StaggeredGridLayoutManager layoutManager = new StaggeredGridLayoutManager(2,StaggeredGridLayoutManager.VERTICAL);

  //添加朋分線
  mRecycle.addItemDecoration(new DividerItemDecoration(getApplicationContext(), DividerItemDecoration.VERTICAL_LIST));


  mRecycle.setLayoutManager(layoutManager);

  mRecycle.setItemAnimator(new DefaultItemAnimator());

  mRecycle.setAdapter(mAdapter);

  mAdapter.refresh();

  /**
   * 設置監聽
   */
  mRecycle.addOnScrollListener(mController);

  mSwipeRefresh.setOnRefreshListener(mController);

 }

 @Override
 public void refresh() {
  //刷新的接口調
  mSwipeRefresh.postDelayed(new Runnable() {
   @Override
   public void run() {
    mAdapter.refresh();
    mSwipeRefresh.setRefreshing(false);
    mController.setLoadDataStatus(false);
   }
  },2000);
 }

 @Override
 public void loadMore() {
  //加載更多的接口回調
  pd = new ProgressDialog(this);
  pd.show();
  mSwipeRefresh.postDelayed(new Runnable() {
   @Override
   public void run() {
    mAdapter.add();
    //設置數據加載停止的監聽狀況
    mController.setLoadDataStatus(false);
    pd.dismiss();
   }
  },2000);
 }
}

貼個後果圖

第二種方法：SwipeToLoadLayout完成上拉加載和下拉刷新

該刷新控件的方法相似於Ultra-pull-to-refresh的應用方法。

以下方法添加該庫：

 repositories {
  maven { url "https://jitpack.io" }
   }

 compile 'com.github.Aspsine:SwipeToLoadLayout:1.0.3'

起首我們須要自界說一個頭視圖和底部視圖，頭部試圖和底部試圖的用法雷同，所以我們先界說一個頭部視圖類：

/**
 * 基本的refreshHeadView
 */
public class RefreshHeaderView extends TextView implements SwipeRefreshTrigger, SwipeTrigger {

 public RefreshHeaderView(Context context) {
  super(context);
 }

 public RefreshHeaderView(Context context, AttributeSet attrs) {
  super(context, attrs);
 }

 public RefreshHeaderView(Context context, AttributeSet attrs, int defStyleAttr) {
  super(context, attrs, defStyleAttr);
 }

 @TargetApi(Build.VERSION_CODES.LOLLIPOP)
 public RefreshHeaderView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
  super(context, attrs, defStyleAttr, defStyleRes);
 }

 @Override
 public void onRefresh() {
  //下拉到必定地位松開以後，挪用此辦法
  setText("refresh");

  Log.i("info","onRefresh");
 }

 @Override
 public void onPrepare() {

  //下拉之前挪用此辦法
  Log.i("info","onPrepare");
 }

 @Override
 public void onMove(int yScrolled, boolean isComplete, boolean automatic) {
  if (!isComplete) {
   //以後Y軸偏移量年夜於控件高度時，標識下拉到界線，顯示“松開已刷新”
   if (yScrolled >= getHeight()) {

   } else {
    //未到達偏移量

   }
  } 
  Log.i("info","onMove");
 }

 @Override
 public void onRelease() {
  //到達必定滑動間隔，松開刷新時挪用
  setText("onRelease");
  Log.i("info","onRelease");
 }

 @Override
 public void onComplete() {
  //加載完成以後挪用此辦法
  setText("complete");
  Log.i("info","onComplete");
 }

 @Override
 public void onReset() {
  //重置
  setText("onReset");
  Log.i("info","onReset");
 }
}

其須要完成接口SwipeRefreshTrigger和SwipeTrigger。

而底部須要完成SwipeTrigger和SwipeLoadMoreTrigger。

結構文件中以下應用

<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:background="#ECEDF0"
 >

 <com.aspsine.swipetoloadlayout.SwipeToLoadLayout
  android:id="@+id/swipeToLoadLayout"
  android:layout_width="match_parent"
  android:layout_height="match_parent">

  <com.mahao.alex.systemwidgetdemo.recycleView.swipetoloadlayout.RefreshHeaderView
   android:id="@+id/swipe_refresh_header"
   android:layout_width="match_parent"
   android:layout_height="wrap_content" />

  <android.support.v7.widget.RecyclerView
   android:id="@+id/swipe_target"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:scrollbars="vertical" />

  <com.mahao.alex.systemwidgetdemo.recycleView.swipetoloadlayout.LoaderMoreView
   android:id="@+id/swipe_load_more_footer"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:gravity="center"
   android:padding="20dp" />
 </com.aspsine.swipetoloadlayout.SwipeToLoadLayout>


</RelativeLayout>

查找控件，設置監聽

swipeToLoadLayout.setOnRefreshListener(this);
swipeToLoadLayout.setOnLoadMoreListener(this);

在我們之前的代碼中，參加了log信息，我們可以看一下log信息。…代表屢次onMove()辦法屢次挪用。

05-10 10:30:34.906 23814-23814/com.mahao.alex.systemwidgetdemo I/info: onMove
..........................................................................
05-10 10:30:35.086 23814-23814/com.mahao.alex.systemwidgetdemo I/info: onMove
05-10 10:30:35.106 23814-23814/com.mahao.alex.systemwidgetdemo I/info: onRefresh
05-10 10:30:37.116 23814-23814/com.mahao.alex.systemwidgetdemo I/info: onComplete
05-10 10:30:37.416 23814-23814/com.mahao.alex.systemwidgetdemo I/info: onMove
..........................................................................
05-10 10:30:37.516 23814-23814/com.mahao.alex.systemwidgetdemo I/info: onMove
05-10 10:30:37.916 23814-23814/com.mahao.alex.systemwidgetdemo I/info: onReset

起首會挪用onPrepare()辦法，onMove()辦法會一向挪用,只需視圖有偏移，就會挪用。下拉到必定間隔以後，松開挪用onRelaease(),回歸到刷新地位時回調onRefresh()，加載完成挪用onComplete()，視圖開端減少，最初隱蔽以後挪用onReset()

依據需求自界說視圖，

OK。確定有小同伴應用該框架時一向報錯，為何，看框架的源碼，有以下一段

this.mHeaderView = this.findViewById(id.swipe_refresh_header);
 this.mTargetView = this.findViewById(id.swipe_target);
 this.mFooterView = this.findViewById(id.swipe_load_more_footer);

可以看出，作者是依據固定的id值獲得的，所以在我們的結構文件中，必需應用固定的三個id。

若有需求，可移步我的github獲得源碼，源碼在systemwidgetdemo中。
