A view which can refresh and load more.It is easy to customizable(see header).It's a simple refresh and load more lib.

More importent,BounceLayout is a bounce view.So you You'd better use a BounceLayout rather than the fixed one:

bounceLayout.setDisallowBounce(true)//disallow the BounceLayout bounce!!!!

How to use

1.add dependencies:
Add it in your root build.gradle at the end of repositories:

allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}   

Add the dependency:

dependencies {
	        implementation 'com.github.BLCodes:LightRefresh:1.0.3-beta-4'
	}

2.use a framlayout(must!!!) to wrap the BounceLayout and header or footer,eg:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
   xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:id="@+id/fl_root"
   >
   <!--the header or footer will be added here-->
   <com.blcodes.views.refresh.BounceLayout
       android:id="@+id/bl"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:background="#eee"
       >
       <android.support.v7.widget.RecyclerView
           android:id="@+id/rv_test"
           android:layout_width="match_parent"
           android:layout_height="match_parent"></android.support.v7.widget.RecyclerView>


   </com.blcodes.views.refresh.BounceLayout>
</FrameLayout> 

3.add header or footer and set the Boolean value to make the view not bounce(if you need):

//bounceLayout.setDisallowBounce(true);//disallow the BounceLayout bounce!!!!
FrameLayout rootView = findViewById(R.id.fl_root);
bounceLayout.setHeaderView(new DefaultHeader(this),rootView);//if HeaderView is null,it just bounce.
bounceLayout.setFooterView(new DefaultFooter(this),rootView);

4.set scroll BounceHandler and EventForwardingHelper call back:

RecyclerView recyclerView = findViewById(R.id.rv_test);
bounceLayout.setBounceHandler(new NormalBounceHandler(),recyclerView);

bounceLayout.setEventForwardingHelper(new EventForwardingHelper() {
            @Override
            public boolean notForwarding(float downX, float downY, float moveX, float moveY) {
                return true;
            }
        });

5.add refresh and load more call back: setbounceLayout.setRefreshCompleted() and bounceLayout.setLoadingMoreCompleted() is very important!!!

bounceLayout.setBounceCallBack(new BounceCallBack() {
            @Override
            public void startRefresh() {
		Log.i(TAG, "run: 开始刷新");
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        ArrayList<String> data = new ArrayList<>();
                        for (int i = 0; i < 16; i++) {
                            data.add("新文本"+i);
                        }
                        adapter.setData(data);
                        bounceLayout.setRefreshCompleted();
                        Log.i(TAG, "run: 结束刷新");
                    }
                },2000);
            }

            @Override
            public void startLoadingMore() {

            }
        });

6.set auto refresh or not(if you need):
