![demo](https://github.com/jianghejie/XRecyclerView/blob/master/art/demo.gif)



on real device it is much more smoother. 

Usage

-----

## gradle

```groovy

// 1.6.0 is the main

compile 'com.jcodecraeer:xrecyclerview:1.6.0'

```

just like a standard RecyclerView

```java

LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());

layoutManager.setOrientation(LinearLayoutManager.VERTICAL);

mRecyclerView.setLayoutManager(layoutManager);

mRecyclerView.setAdapter(mAdapter);

```

## pull to refresh and load more

the pull to refresh and load more featrue is enabled by default. we provide a callback to trigger the refresh and LoadMore event.

```java

 mRecyclerView.setLoadingListener(new XRecyclerView.LoadingListener() {

    @Override

    public void onRefresh() {

       //refresh data here

    }



    @Override

    public void onLoadMore() {

       // load more data here

    }

});

```

new function of 1.5.7 version.

```java

mRecyclerView

    .getDefaultRefreshHeaderView() // get default refresh header view

    .setRefreshTimeVisible(true);  // make refresh time visible,false means hiding



// if you are not sure that you are 100% going to

// have no data load back from server anymore,do not use this

@Deprecated

public void setEmptyView(View emptyView) {

    ...

}

```



new function of 1.5.6 version,fixed a memory leak problem,use the code below to release XR's memory

```java

// any time,when you finish your activity or fragment,call this below

if(mRecyclerView != null){

    mRecyclerView.destroy(); // this will totally release XR's memory

    mRecyclerView = null;

}

```



new function of 1.5.3 version,you can use XR in the sticky scroll model now,like the code below,the demo activity is 'LinearStickyScrollActivity'

```java

final View topView = findViewById(R.id.topView);

final View tabView = findViewById(R.id.tabView);

final View content = findViewById(R.id.contentView);



final StickyScrollLinearLayout s = findViewById(R.id.StickyScrollLinearLayout);

s.addOnLayoutChangeListener(

        new View.OnLayoutChangeListener() {

            @Override

            public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {

                if(s.getContentView() != null)

                    return;

                // 放在这里是为了等初始化结束后再添加，防止 height 获取 =0

                // add from here just in case they height==0

                s.setInitInterface(

                        new StickyScrollLinearLayout.StickyScrollInitInterface() {

                            @Override

                            public View setTopView() {

                                return topView;

                            }



                            @Override

                            public View setTabView() {

                                return tabView;

                            }



                            @Override

                            public View setContentView() {

                                return content;

                            }

                        }

                );

            }

        }

);

```



call notifyItemRemoved or notifyItemInserted, remember to use the functions inside XRecyclerView

```java

listData.remove(pos);

mRecyclerView.notifyItemRemoved(listData,pos);

```



and of course you have to tell our RecyclerView when the refreshing or loading more work is done.

you can use

```java

mRecyclerView.loadMoreComplete();

```



to control when the item number of the screen is list.size-2,we call the onLoadMore



```java

mRecyclerView.setLimitNumberToCallLoadMore(2); // default is 1

```



to notify that the loading more work is done.

and



```java

 mRecyclerView.refreshComplete();

```



to notify that the refreshing work is done.



here is what we get:

## call refresh() manually(I change the previous setRefreshing() method to refresh() )



```java

mRecyclerView.refresh();

```



### custom refresh and loading more style

pull refresh and loading more style is highly customizable.



#### custom loading style

the loading effect we use the  [AVLoadingIndicatorView](https://github.com/81813780/AVLoadingIndicatorView) . and it is built in(make a little change).

we provide all the effect in AVLoadingIndicatorView library besides we add a system style.

you can call 

```java

mRecyclerView.setRefreshProgressStyle(int style);

```

and 

```java

mRecyclerView.setLaodingMoreProgressStyle(int style);

```

to set the RefreshProgressStyle and  LaodingMoreProgressStyle respectively.



for example

```java

mRecyclerView.setRefreshProgressStyle(ProgressStyle.BallSpinFadeLoader);

```

![refreshloadingballspinfade](https://github.com/jianghejie/XRecyclerView/blob/master/art/refreshloadingballspinfade.gif)

```java

mRecyclerView.setLaodingMoreProgressStyle(ProgressStyle.SquareSpin);

```

![loadingmoresquarespin](https://github.com/jianghejie/XRecyclerView/blob/master/art/loadingmoresquarespin.gif)



BallPulse  effect



![BallPulse](https://github.com/jianghejie/XRecyclerView/blob/master/art/ballpulse.gif)



all the effect can be get in the ProgressStyle class



```java

public class ProgressStyle {

    public static final int SysProgress=-1;

    public static final int BallPulse=0;

    public static final int BallGridPulse=1;

    public static final int BallClipRotate=2;

    public static final int BallClipRotatePulse=3;

    public static final int SquareSpin=4;

    public static final int BallClipRotateMultiple=5;

    public static final int BallPulseRise=6;

    public static final int BallRotate=7;

    public static final int CubeTransition=8;

    public static final int BallZigZag=9;

    public static final int BallZigZagDeflect=10;

    public static final int BallTrianglePath=11;

    public static final int BallScale=12;

    public static final int LineScale=13;

    public static final int LineScaleParty=14;

    public static final int BallScaleMultiple=15;

    public static final int BallPulseSync=16;

    public static final int BallBeat=17;

    public static final int LineScalePulseOut=18;

    public static final int LineScalePulseOutRapid=19;

    public static final int BallScaleRipple=20;

    public static final int BallScaleRippleMultiple=21;

    public static final int BallSpinFadeLoader=22;

    public static final int LineSpinFadeLoader=23;

    public static final int TriangleSkewSpin=24;

    public static final int Pacman=25;

    public static final int BallGridBeat=26;

    public static final int SemiCircleSpin=27;

}

```

#### refresh arrow icon

we provide a default arrow icon:



![ic_pulltorefresh_arrow](https://github.com/jianghejie/XRecyclerView/blob/master/art/ic_pulltorefresh_arrow.png)



but if you don't like it,you can replace it with any other icon  you want.

just call

```java

mRecyclerView.setArrowImageView(R.drawable.iconfont_downgrey);

```

![customarrow](https://github.com/jianghejie/XRecyclerView/blob/master/art/customarrow.gif)

### disable refresh and load more featrue

if you don't want the refresh and load more featrue(in that case,you probably dont'n need the lib neither),you can call

```java

mRecyclerView.setPullRefreshEnabled(false);

```

and

```java

mRecyclerView.setPullRefreshEnabled(true);

```

in which false means disabled ,true means enabled.

##Header

you can add header to XRecyclerView，just call addHeaderView().



```java

View header =   LayoutInflater.from(this).inflate(R.layout.recyclerview_header, (ViewGroup)findViewById(android.R.id.content),false);

mRecyclerView.addHeaderView(header);

```

if you like ,you can add two header



```java

View header =   LayoutInflater.from(this).inflate(R.layout.recyclerview_header, (ViewGroup)findViewById(android.R.id.content),false);

View header1 =   LayoutInflater.from(this).inflate(R.layout.recyclerview_header1, (ViewGroup)findViewById(android.R.id.content),false);

mRecyclerView.addHeaderView(header);

mRecyclerView.addHeaderView(header1);

```
