# 使用方法  

xml



     



        



    



代码



     coolRefreshView.setPullHeader(new MaterialHeader(getContext()));

     //添加刷新监听

     coolRefreshView.addOnPullListener(new SimpleOnPullListener() {

            @Override

            public void onRefreshing(CoolRefreshView refreshView) {

                

            }

        });



# 其它可用方法  



设置全局的IPullHeaderFactory



	  //静态设置全局的IPullHeaderFactory，一次配置，所有默认使用这个factory生成的PullHeader

	  //就不用每个界面设置，该代码可以放在Application onCreate



	  CoolRefreshView.setPullHeaderFactory(new IPullHeaderFactory() {

	      @Override

	      public PullHeader made(Context context) {

	          JellyHeader jellyHeader = new JellyHeader(getContext());

	          jellyHeader.setDragLayoutColor(ContextCompat.getColor(getContext(), R.color.primary));

	          jellyHeader.setLoadingView(R.layout.layout_jelley_header);

	          return jellyHeader;

	      }

	

	      @Override

	      public boolean isPinContent() {

	          return false;

	      }

	  });

设置ContentView是否和头部一起下拉



    /**

     * @param pullHeader   刷新的头部

     * @param isPinContent true滚定内容不下拉，只下拉头部， false 一起下拉

     */

    setPullHeader(PullHeader pullHeader, boolean isPinContent) 



# 自定义Header

##<1>简单的实现  

实现PullHeader



	public class TestHeader implements PullHeader {

	    private View headView;

	    private TextView mTextView;

	

	    @Override

	    public View createHeaderView(final CoolRefreshView refreshView) {

	        headView = LayoutInflater.from(refreshView.getContext()).inflate(R.layout.coolrecyclerview_testhead, refreshView, false);

	        mTextView = (TextView) headView.findViewById(R.id.coolrecyclerview_testhead_text1_textView);

	        return headView;

	    }

	

	    /**

	     * 开始拖动

	     */

	    @Override

	    public void onPullBegin(CoolRefreshView refreshView) {

	        isDownArrow = true;

	    }

	

	    /**

	     * 位置变化

	     *

	     * @param refreshView

	     * @param status          状态 /没有任何操作

	     *                        public final static byte PULL_STATUS_INIT = 1;

	     *                        //开始下拉

	     *                        public final static byte PULL_STATUS_TOUCH_MOVE = 2;

	     *                        //回到原始位置

	     *                        public final static byte PULL_STATUS_RESET = 3;

	     *                        //刷新中

	     *                        public final static byte PULL_STATUS_REFRESHING = 4;

	     *                        //刷新完成

	     *                        public final static byte PULL_STATUS_COMPLETE = 5;

	     * @param dy              下拉事件的位移

	     * @param currentDistance 当前位移的距离

	     */

	    @Override

	    public void onPositionChange(CoolRefreshView refreshView, int status, int dy, int currentDistance) {

	        int offsetToRefresh = getConfig().offsetToRefresh(refreshView, headView);

	        if (status == CoolRefreshView.PULL_STATUS_TOUCH_MOVE) {

	            if (currentDistance < offsetToRefresh) {

	                if (!isDownArrow) {

	                    mTextView.setText("下拉刷新");

	                    isDownArrow = true;

	                }

	            } else {

	                if (isDownArrow) {

	                    mTextView.setText("释放立即刷新");

	                    isDownArrow = false;

	                }

	            }

	        }

	    }

	

	    private boolean isDownArrow;

	

	    /**

	     * 刷新中

	     */

	    @Override

	    public void onRefreshing(CoolRefreshView refreshView) {

	        mTextView.setText("刷新中..");

	    }

	

	    /**

	     * 没有刷新的释放回去

	     */

	    @Override

	    public void onReset(CoolRefreshView refreshView, boolean pullRelease) {

	

	    }

	

	    /**

	     * 设置刷新完成，并且释放回去

	     */

	    @Override

	    public void onPullRefreshComplete(CoolRefreshView frame) {

	

	    }

	

	    @Override

	    public Config getConfig() {

	        return config;

	    }

	

		//使用默认的配置

	    private DefaultConfig config = new DefaultConfig();

	

	}



也可以直接继承View 实现 PullHeader



	public class TestHeader extends View  implements PullHeader {

	    @Override

	    public View createHeaderView(final CoolRefreshView refreshView) {

	        return this;

	    }

	}



##<2>配置距离，可以实现更丰富的效果



	 abstract class Config {

	        /**

	         * 超出这个偏移量，松开手指就会触发刷新。

	         */

	        public abstract int offsetToRefresh(CoolRefreshView refreshView, View headerView);

	

	        /**

	         * 显示刷新的位置的偏移量

	         */

	        public abstract int offsetToKeepHeaderWhileLoading(CoolRefreshView refreshView, View headerView);

	

	        /**

	         * 刷新控件总共可以下拉拖动的距离

	         */

	        public abstract int totalDistance(CoolRefreshView refreshView, View headerView);

	

	        /**

	         * headView 在布局中的偏移量

	         */

	        public abstract int headerViewLayoutOffset(CoolRefreshView refreshView, View headerView);

	

	        /**

	         * contentView 是否可以向上滚动，用来判断是否可以下拉刷新，如果可以向上滚动就不做下拉刷新动作

	         */

	        public abstract boolean contentCanScrollUp(CoolRefreshView refreshView, View contentView);

	

	        /**

	         * 拦截滑动事件

	         *

	         * @param refreshView

	         * @param dy              触摸滑动的偏移量

	         * @param currentDistance 当前的滑动的距离

	         * @param totalDistance   总的可下拉距离

	         * @return

	         */

	        public abstract int dispatchTouchMove(CoolRefreshView refreshView, int dy, int currentDistance, int totalDistance);

	

	    }



  **默认的配置**



    //滑动的总距离是header高度3倍

    //触发刷新的距离是header的1.2倍

    //正在刷新中的距离是header的高度

	class DefaultConfig extends Config {



        @Override

        public int offsetToRefresh(CoolRefreshView refreshView, View headerView) {

            return (int) (headerView.getMeasuredHeight() * 1.2f);

        }



        @Override

        public int offsetToKeepHeaderWhileLoading(CoolRefreshView refreshView, View headerView) {

            return headerView.getMeasuredHeight();

        }



        @Override

        public int totalDistance(CoolRefreshView refreshView, View headerView) {

            return headerView.getMeasuredHeight() * 3;

        }



		.....

    }



  **第二种常用的配置**



    //总的滑动是header的高度，也就是滑动显示的区域控制在header里

    //正在刷新的距离是header3分之一，在header底部的3分之一区域作为正在刷新中的区域

    //触发刷新的距离是正在刷新距离的1.2倍.



 	private DefaultConfig config = new DefaultConfig() {

        @Override

        public int offsetToRefresh(CoolRefreshView refreshView, View headerView) {

            return (int) (headerView.getMeasuredHeight() / 3 * 1.2f);

        }



        @Override

        public int offsetToKeepHeaderWhileLoading(CoolRefreshView refreshView, View headerView) {

            return headerView.getMeasuredHeight() / 3;

        }



        @Override

        public int totalDistance(CoolRefreshView refreshView, View headerView) {

            return headerView.getMeasuredHeight();

        }

    };



##配合MVCHelper类库使用，上滑加载更多

配合

https://github.com/LuckyJayce/MVCHelper   

代码只要5行，就可以实现下拉刷新，滚动底部自动加载更多，分页加载，自动切换显示网络失败布局，暂无数据布局



    CoolRefreshView coolRefreshView = (CoolRefreshView) findViewById(R.id.coolRefreshView);

    MVCHelper> mvcHelper = new MVCCoolHelper>(coolRefreshView);



    // 设置数据源

    mvcHelper.setDataSource(new BooksDataSource());

    // 设置适配器

    mvcHelper.setAdapter(new BooksAdapter(this));



    // 加载数据

    mvcHelper.refresh();



更多的详细使用参照 https://github.com/LuckyJayce/MVCHelper 的demo



## 说明



  滑动事件的处理是参照 v4包的 SwipeRefreshLayout，从而支持了支持NestedScrollingParent,NestedScrollingChild的事件分发和避免了嵌套 ViewPager事件冲突  



  结构是参考  https://github.com/liaohuqiu/android-Ultra-Pull-To-Refresh 的结构，它的结构很不错。可以让使用者根据需求自定义Header



  Header的下拉我采用了两种实现  

  <1>Header下拉，内容固定不下拉采用 ViewCompat.offsetTopAndBottom(mHeaderView, -deltaY);  

  <2>Header和内容一起下拉的采用 scrollTo的方式一起滑动.
