18 | mRecyclerView.setAdapter(mHeaderAndFooterRecyclerViewAdapter); 19 | 20 | mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); 21 | 22 | //add a HeaderView 23 | RecyclerViewUtils.setHeaderView(mRecyclerView, new SampleHeader(this)); 24 | 25 | //add a FooterView 26 | RecyclerViewUtils.setFooterView(mRecyclerView, new SampleFooter(this)); 27 | ``` 28 | 29 | * LinearLayout/GridLayout/StaggeredGridLayout布局的RecyclerView分页加载 30 | 31 | ```java 32 | mRecyclerView.addOnScrollListener(mOnScrollListener); 33 | ``` 34 | 35 | ```java 36 | private EndlessRecyclerOnScrollListener mOnScrollListener = new EndlessRecyclerOnScrollListener() { 37 | 38 | @Override 39 | public void onLoadNextPage(View view) { 40 | super.onLoadNextPage(view); 41 | 42 | LoadingFooter.State state = RecyclerViewStateUtils.getFooterViewState(mRecyclerView); 43 | if(state == LoadingFooter.State.Loading) { 44 | Log.d("@Cundong", "the state is Loading, just wait.."); 45 | return; 46 | } 47 | 48 | mCurrentCounter = mDataList.size(); 49 | 50 | if (mCurrentCounter < TOTAL_COUNTER) { 51 | // loading more 52 | RecyclerViewStateUtils.setFooterViewState(EndlessLinearLayoutActivity.this, mRecyclerView, REQUEST_COUNT, LoadingFooter.State.Loading, null); 53 | requestData(); 54 | } else { 55 | //the end 56 | RecyclerViewStateUtils.setFooterViewState(EndlessLinearLayoutActivity.this, mRecyclerView, REQUEST_COUNT, LoadingFooter.State.TheEnd, null); 57 | } 58 | } 59 | }; 60 | ``` 61 | ## 注意事项 62 | 63 | 如果已经使用 ```RecyclerViewUtils.setHeaderView(mRecyclerView, view);``` 为RecyclerView添加了HeaderView，那么再调用ViewHolder类的```getAdapterPosition()```、```getLayoutPosition()```时返回的值就会因为增加了Header而受影响（返回的position等于真实的position+headerCounter）。 64 | 65 | 因此，这种情况下请使用 66 | ```RecyclerViewUtils.getAdapterPosition(mRecyclerView, ViewHolder.this)```、```RecyclerViewUtils.getLayoutPosition(mRecyclerView, ViewHolder.this)``` 两个方法来替代。 67 | 68 | ## Demo 69 | 70 | * 添加HeaderView、FooterView 71 | 72 | ![截屏][1] 73 | 74 | * 支持分页加载的LinearLayout布局RecyclerView 75 | 76 | ![截屏][2] 77 | 78 | * 支持分页加载的GridLayout布局RecyclerView 79 | 80 | ![截屏][3] 81 | 82 | * 支持分页加载的StaggeredGridLayout布局RecyclerView 83 | 84 | ![截屏][4] 85 | 86 | * 分页加载失败时的GridLayout布局RecyclerView 87 | 88 | ![截屏][5] 89 | 90 | ## 关于我 91 | 92 | * Blog: [http://my.oschina.net/liucundong/blog][6] 93 | * Mail: cundong.liu#gmail.com 94 | 95 | ## License 96 | 97 | Copyright 2015 Cundong 98 | 99 | Licensed under the Apache License, Version 2.0 (the "License");
