 Thanks to [Yalantis](https://github.com/Yalantis) for creating a great logic of `PullToRefresh`. And that's logic is the fundation of `PullLaunchRocket` also.
 
 ![sample](https://raw.github.com/lubeast/PullLaunchRocket/master/screenshots/sample.gif)
+
+### Usage
+*You can have a look at Sample Project* `sample` for better use.
+1.include the library as local library project in your module-level `build.gradle`
+```groove
+compile 'com.lumenghz'
+```
+
+2. `PullToRefreshView` widget in your layout.xml
+```xml
+<lumenghz.com.pullrefresh.PullToRefreshView
+        android:id="@+id/pull_to_refresh"
+        android:layout_width="match_parent"
+        android:layout_height="match_parent"
+        app:lrefresh="rocket"
+        >
+
+        <ListView
+            android:id="@+id/list_view"
+            android:layout_width="match_parent"
+            android:layout_height="match_parent"
+            android:divider="@null"
+            android:dividerHeight="0dp"
+            android:fadingEdge="none"
+            />
+
+</lumenghz.com.pullrefresh.PullToRefreshView>
+```
+
+3. Initial the `PullToRefreshView` and setup `OnRefreshListener` in your `onCreate` method
+```java
+mPullToRefreshView.setOnRefreshListener(new PullToRefreshView.OnRefreshListener() {
+    @Override
+    public void onRefresh() {
+        mPullToRefreshView.postDelayed(new Runnable() {
+            @Override
+            public void run() {
+                mPullToRefreshView.setRefreshing(false);
+            }
+        }, REFRESH_DELAY);
+    }
+ });
+```
+
+4.You can change refresh state through call
+```java
+mPullToRefreshView.setRefreshing(boolean isRefreshing)
+```

+
+感谢[Yalantis](https://github.com/Yalantis)为下拉刷新创建了一个炒鸡棒的逻辑案例, 也是`PullLaunchRocket`的基础.
+
+![sample](https://raw.github.com/lubeast/PullLaunchRocket/master/screenshots/sample.gif)
+
+### 使用
+*为了更好使用也可参照示例工程`sample`*
+
+1.在module层级`build.gradle`中加入
+`compile 'com.lumenghz.'pullrefresh`
+2.在布局文件中使用`PullToRefreshView`
+```xml
+<lumenghz.com.pullrefresh.PullToRefreshView
+        android:id="@+id/pull_to_refresh"
+        android:layout_width="match_parent"
+        android:layout_height="match_parent"
+        app:lrefresh="rocket"
+        >
+
+        <ListView
+            android:id="@+id/list_view"
+            android:layout_width="match_parent"
+            android:layout_height="match_parent"
+            android:divider="@null"
+            android:dividerHeight="0dp"
+            android:fadingEdge="none"
+            />
+
+</lumenghz.com.pullrefresh.PullToRefreshView>
+```
+3.在`onCreate`方法中初始化此View并添加刷新监听
+```java
+mPullToRefreshView.setOnRefreshListener(new PullToRefreshView.OnRefreshListener() {
+    @Override
+    public void onRefresh() {
+        mPullToRefreshView.postDelayed(new Runnable() {
+            @Override
+            public void run() {
+                mPullToRefreshView.setRefreshing(false);
+            }
+        }, REFRESH_DELAY);
+    }
+ });
+```
+4.你可以调用`mPullToRefreshView.setRefreshing(boolean isRefreshing);`修改刷新状态.
