3 | # 概述
4 | > 这是一个通用的下拉刷新、上拉自动加载的组件，该组件继承自LinearLayout,方向为竖直布局，由三部分组成，分别是Header、ContentView、Foooter,其中ContentView的宽高都为match_parent,footer和header的宽、高分别为match_parent、wrap_content，在Header、Foooter初始时都会通过设置padding隐藏掉，只有
5 | ContentView区域显示出来。当用户下拉到顶端，并且继续下拉时触发下拉刷新操作；当用户上拉到底部，
6 | > 并且继续上拉时触发加载更多的操作。

19 | ## 二、已有组件的使用示例
20 | 下面的例子都是在一个Activity中演示。
21 | ### 2.1 使用PullRefreshListView
22 | ```java
23 | public class MainActivity extends Activity {
24 |
25 | ListView mListView;
26 |
27 | PullRefreshListView mPullRefreshListView;
28 |
29 | @Override
30 | protected void onCreate(Bundle savedInstanceState) {
31 | super.onCreate(savedInstanceState);
32 |
33 | // 下拉刷新的listview
34 | mPullRefreshListView = new PullRefreshListView(this);
35 | // 获取listview 对象, 即PullRefreshListView中的mContentView
36 | mListView = mPullRefreshListView.getContentView();
37 |
38 | List datas = new ArrayList();
39 | for (int i = 0; i < 5; i++) {
40 | datas.add(" Item - " + i);
41 | }
42 |
43 | // 设置adapter
44 | mListView.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1,
45 | datas));
46 |
47 | // 下拉刷新
48 | mPullRefreshListView.setOnRefreshListener(new OnPullRefreshListener() {
49 |
50 | @Override
51 | public void onRefresh() {
52 |
53 | Toast.makeText(getApplicationContext(), "refresh", Toast.LENGTH_SHORT).show();
54 | mPullRefreshListView.postDelayed(new Runnable() {
55 |
56 | @Override
57 | public void run() {
58 | mPullRefreshListView.refreshComplete();
59 | }
60 | }, 2000);
61 | }
62 | });
63 | // 上拉自动加载
64 | mPullRefreshListView.setOnLoadMoreListener(new OnLoadMoreListener() {
65 |
66 | @Override
67 | public void onLoadMore() {
68 | Toast.makeText(getApplicationContext(), "load more", Toast.LENGTH_SHORT).show();
69 | mPullRefreshListView.postDelayed(new Runnable() {
70 |
71 | @Override
72 | public void run() {
73 | mPullRefreshListView.loadMoreComplete();
74 | }
75 | }, 1500);
76 | }
77 | });
78 |
79 |
80 | setContentView(mPullRefreshListView);
81 |
82 | }
83 | }
84 | ```
85 | **下拉刷新截图**
86 |
87 | 
88 |
89 | **上拉到底部的自动加载**
90 | 
91 |
92 | ### 2.2 使用可下拉刷新的TextView
93 | ```java
94 |
95 | public class MainActivity extends Activity {
96 |
97 | @Override
98 | protected void onCreate(Bundle savedInstanceState) {
99 | super.onCreate(savedInstanceState);
100 |
101 | // PullRefreshTextView
102 | final PullRefreshTextView pullRefreshTextView = new PullRefreshTextView(this);
103 | pullRefreshTextView.getContentView().setText("下拉刷新TextView");
104 | // 下拉刷新
105 | pullRefreshTextView.setOnRefreshListener(new OnPullRefreshListener() {
106 |
107 | @Override
108 | public void onRefresh() {
109 | pullRefreshTextView.getContentView().setText(new Date().toGMTString());
110 | pullRefreshTextView.postDelayed(new Runnable() {
111 |
112 | @Override
113 | public void run() {
114 | pullRefreshTextView.refreshComplete();
115 | }
116 | }, 1000);
117 | }
118 | });
119 |
120 | // 上拉自动加载, TextView不能设置scroll listener ，所以无效
121 | pullRefreshTextView.setOnLoadMoreListener(new OnLoadMoreListener() {
122 |
123 | @Override
124 | public void onLoadMore() {
125 | Toast.makeText(getApplicationContext(), "textview load", Toast.LENGTH_SHORT).show();
126 | pullRefreshTextView.postDelayed(new Runnable() {
127 |
128 | @Override
129 | public void run() {
130 | pullRefreshTextView.loadMoreComplete();
131 | }
132 | }, 1000);
133 | }
134 | });
135 |
136 | setContentView(pullRefreshTextView);
137 |
138 |
139 | }
140 | }
141 | ```
142 | **截图**
143 |
144 | 
145 |
146 | ## 三、扩展该组件
147 | ### 3.1、继承自PullRefreshBase
148 | T为你要实现下拉刷新的View的类型，如ListView.
149 |
150 | ### 3.2、初始化ContentView
151 | 覆写initContentView方法，并且在该函数中初始化mContentView对象。我们以ListView为例，例如 :
152 | ```java
153 | /*
154 | * 初始化mContentView
155 | * @see com.uit.pullrefresh.base.PullRefreshBase#initContentView()
156 | */
157 | @Override
158 | protected void initContentView() {
159 | // 初始化mContentView
160 | mContentView = new ListView(getContext());
161 | // 设置OnScrollListener, 用以实现滑动到底部时的自动加载功能，如果不需要该功能可以不设置.
162 | mContentView.setOnScrollListener(this);
163 | }
164 | ```
165 |
166 | ### 3.3、覆写判断是否滑动到顶端和底部的方法
167 | 我们以ListView为例，例如 :
168 | ```java
169 | /*
170 | * 是否滑动到了顶端，如果返回true, 则表示到了顶端，用户继续下拉则触发下拉刷新
171 | * @see com.uit.pullrefresh.base.PullRefreshBase#isTop()
172 | */
173 | @Override
174 | protected boolean isTop() {
175 | View firstChild = mContentView.getChildAt(0);
176 | if (firstChild == null) {
177 | return true;
178 | }
179 | return mContentView.getFirstVisiblePosition() == 0
180 | && (firstChild.getTop() >= mContentView.getTop());
181 | }
182 |
183 | /*
184 | * 下拉到listview 最后一项时则返回true, 将出发自动加载
185 | * @see com.uit.pullrefresh.base.PullRefreshBase#isShowFooterView()
186 | */
187 | @Override
188 | protected boolean isShowFooterView() {
189 | if (mContentView == null || mContentView.getAdapter() == null) {
190 | return false;
191 | }
192 |
193 | return mContentView.getLastVisiblePosition() == mContentView.getAdapter().getCount() - 1;
194 | }
195 | ```
196 | ### 3.4使用即可
