Add the JitPack repository to your build file 32 | Add it in your root build.gradle at the end of repositories: 33 | ```gradle 34 | allprojects { 35 | repositories { 36 | ... 37 | maven { url 'https://jitpack.io' } 38 | } 39 | } 40 | ``` 41 | 42 | Step 2. Add the dependency 43 | ```gradle 44 | dependencies { 45 | implementation 'com.github.nukc:LoadMoreWrapper:v1.9.1' 46 | } 47 | ``` 48 | AndroidX 49 | ```gradle 50 | dependencyResolutionManagement { 51 | repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS) 52 | repositories { 53 | ... 54 | maven("https://jitpack.io") 55 | } 56 | } 57 | ``` 58 | ```gradle 59 | dependencies { 60 | implementation("com.github.nukc:LoadMoreWrapper:v1.9.3") 61 | } 62 | ``` 63 | 64 | ## Usage 65 | 66 | ```java 67 | //the adapter is the original (这个 adapter 是原有的, 不改动它) 68 | LoadMoreWrapper.with(adapter) 69 | .setFooterView(...) // view or layout resource 70 | .setShowNoMoreEnabled(true) // enable show NoMoreView，default false 71 | .setListener(new LoadMoreAdapter.OnLoadMoreListener() { 72 | @Override 73 | public void onLoadMore(LoadMoreAdapter.Enabled enabled) { 74 | // do something 75 | // you can enabled.setLoadMoreEnabled(false) when do not need load more 76 | // you can enabled.setLoadFailed(true) when load failed 77 | }) 78 | .into(recyclerView); 79 | ``` 80 | 81 | or 82 | 83 | in the original adapter: [demo](https://github.com/nukc/LoadMoreWrapper/blob/master/app/src/main/java/com/github/nukc/sample/AnotherActivity.java) 84 | ```java 85 | private static class AnotherAdapter extends RecyclerView.Adapter { 86 | 87 | private LoadMoreWrapper mWrapper; 88 | 89 | // code.. 90 | 91 | @Override 92 | public void onAttachedToRecyclerView(RecyclerView recyclerView) { 93 | super.onAttachedToRecyclerView(recyclerView); 94 | 95 | mWrapper = LoadMoreWrapper.with(this); 96 | mWrapper.setListener( 97 | new LoadMoreAdapter.OnLoadMoreListener() { 98 | @Override 99 | public void onLoadMore(LoadMoreAdapter.Enabled enabled) { 100 | // do something 101 | } 102 | }) 103 | .setShowNoMoreEnabled(true) 104 | .into(recyclerView); 105 | } 106 | 107 | } 108 | 109 | ``` 110 | 111 | 方法名 | 备注 112 | :------------- | :------------- 113 | setLoadMoreEnabled(boolean enabled) | 设置是否启用加载更多，默认 true 114 | setShowNoMoreEnabled(boolean enabled) | 设置全部加载完后是否显示没有更多视图，默认 false 115 | setLoadFailed(boolean isLoadFailed) | 设置是否加载失败，默认 false 116 | setNotShowFooterWhenNotCoveredScreen(boolean notShow) | 设置在 item 未铺满屏幕的时候是否不显示底部视图，默认 false 117 | getOriginalAdapter() | 获取原来的 adapter 118 | getFooterView | 获取加载更多视图 119 | getNoMoreView | 获取没有更多视图 120 | getLoadFailedView | 获取加载失败视图 121 | 122 | 注意：当加载完全部后且已 setLoadMoreEnabled(false)，但如果由于生命周期或其他问题而导致 View 重建，mLoadMoreEnabled 依然为 true。 123 | 这时候应该需要保存 mLoadMoreEnabled 的状态，如果是 ViewPager + Fragment，可以使用 setOffscreenPageLimit 进行解决。 124 | 125 | ## License 126 | 127 | Copyright 2016 nukc 128 | 129 | Licensed under the Apache License, Version 2.0 (the "License");
