-# MVVMLight
-A toolkit help to build Android MVVM Application
+# MVVM Light Toolkit
+A toolkit help to build Android MVVM Application，We have more
+attributes for Data Binding  of View(like Uri for ImageView) ,we create some command for deal with event( like click of Button),also have a global message pipe to communicate with other ViewModel.
+##Download##
+
+```groovy
+ compile 'com.kelin.mvvmlight:library:0.6.0'
+```
+ 
+requires at least android gradle plugin 1.5.0.
+
+##Usage##
+---
+###Data Binding###
+
+
+Binding URI to the ImageView with bind:uri will make it loading bitmap from URI and render to ImageView automatically.
+
+   ```xml
+   <ImageView
+     android:layout_width="match_parent"
+     android:layout_height="match_parent"
+     android:layout_alignParentRight="true"
+     bind:uri="@{viewModel.imageUrl}"
+     bind:placeholderImageRes="@{R.drawable.ic_launcher}"/>
+   ```
+   
+   ---  
+    
+   **Example**
+
+   ![image.gif](http://upload-images.jianshu.io/upload_images/966283-2e13447dfd5028a1.gif?imageMogr2/auto-orient/strip)
+   
+   ---
+
+AdapterView like ListView、RecyclerView 、ViewPager is convenient, bind it to the collection view with app:items and app:itemView,You should use an ObservableList to automatically update your view based on list changes.
+
+   ```xml
+    <android.support.v7.widget.RecyclerView
+       android:layout_width="match_parent"
+       android:layout_height="match_parent"
+       bind:itemView="@{viewModel.itemView}"
+       bind:items="@{viewModel.itemViewModel}"
+       bind:layoutManager="@{LayoutManagers.linear()}"
+   ```
+   
+   In ViewModel define itemViewModel and itemView
+   
+   ```java
+    public final ObservableList<ViewModel> itemViewModel = new ObservableArrayList<>();
+    public final ItemView itemView = ItemView.of(BR.viewModel, R.layout.layoutitem_list_view);
+   ```
+   
+   Adapter，ViewHolder ..is Not Required:
+   
+   ---   
+   
+   **Example**
+   
+   ![listview_databinding.gif](http://upload-images.jianshu.io/upload_images/966283-fb4ae1cdc79ff478.gif?imageMogr2/auto-orient/strip)
+   
+   ---
+ **Other attributes supported:**
+
+  - *ImageView*
+
+     ```xml
+     <attr name="uri" />
+     <!--width for ResizeOptions (use Fresco to load bitmap). -->
+     <attr name="request_width" format="integer" />
+     <!--height for ResizeOptions (use Fresco to load bitmap). -->
+     <attr name="request_height" format="integer" />
+     <attr name="placeholderImageRes" format="reference|color" />
+      ```
+
+  - *ListView*、*ViewPager*、*RecyclerView*
+
+     ```xml
+     <!-- require ItemView  or  ItemViewSelector   -->
+     <attr name="itemView" />
+     <!-- require List<ViewModel> bind to ItemView to presentation.-->
+     <attr name="items" />
+     <!-- require a adapter which type of BindingRecyclerViewAdapter<T> to AdapterView-->
+     <attr name="adapter" />
+     <attr name="dropDownItemView" format="reference" />
+     <attr name="itemIds" format="reference" />
+     <attr name="itemIsEnabled" format="reference" />
+     <!-- require PageTitles<T>-->
+     <attr name="pageTitles" format="reference" />
+     ```
+
+  - *ViewGroup*
+
+     ```xml
+     <!-- require ItemView  or ItemViewSelector -->
+     <attr name="itemView" />
+     <!-- require List<ViewModel> bind to ItemView to presentation.-->
+     <attr name="viewModels" format="reference" />
+     ```
+
+  - *EditText*
+
+     ```xml
+     <!-- require boolean value to decide whether requestFocus for view. -->
+     <attr name="requestFocus"  format="boolean" />
+     ```
+
+  - *SimpleDraweeView*
+
+     ```xml
+     <!-- require String to load Image"-->
+     <attr name="uri" />
+     ```
+
+  - *WebView*
+
+     ```xml
+     <!-- require String render to html show in webview-->
+     <attr name="render" format="string" />
+     ```
+
+
+###Command Binding###
+---
+
+When RecyclerView scroll to end of list,we have onLoadMoreCommand to deal with event.
+
+   ```xml
+      <android.support.v7.widget.RecyclerView
+           android:id="@+id/recyclerView"
+           android:layout_width="match_parent"
+           android:layout_height="match_parent"
+           bind:onLoadMoreCommand="@{viewModel.loadMoreCommand}"/>
+   ```
+
+In ViewModel define a ReplyCommand<Integer> field to deal with this event.
+
+  ```java
+     public final ReplyCommand<Integer> loadMoreCommand = new ReplyCommand<>(
+        (count) -> {
+            /*count: count of list items*/
+             int page=count / LIMIT +1;
+             loadData(page)
+        });
+  ```
+  
+   ---   
+   
+   **Example**
+  
+   ![listview load more](http://upload-images.jianshu.io/upload_images/966283-4774960c95b4e1e5.gif?imageMogr2/auto-orient/strip)
+ 
+   ---
+ 
+   Deal with click event of View is more convenient:
+
+  ```xml
+   <Button
+              android:layout_width="match_parent"
+              android:layout_height="wrap_content"
+              bind:clickCommand="@{viewModel.btnClickCommand}" />
+  ```
+In ViewModel define a ReplyCommand btnClickCommand will be call when click event occur.
+
+  ```java
+   public ReplyCommand btnClickCommand = new ReplyCommand(() -> {
+         do something...
+      });
+  ```
+  
+  ---   
+  
+  **Example** 
+   
+  ![clickCommand.gif](http://upload-images.jianshu.io/upload_images/966283-127546f950733b22.gif?imageMogr2/auto-orient/strip)
+  
+  ---
+  
+  **onRefreshCommand to SwipeRefreshLayout**
+  
+   ![refresh.gif](http://upload-images.jianshu.io/upload_images/966283-ea1e70f3282003aa.gif?imageMogr2/auto-orient/strip)
+   
+  ---
+  
+More command binding is supported:
+
+  - *View*
+
+    ```xml
+    <!-- require ReplyCommand to deal with view click event. -->
+    <attr name="clickCommand" format="reference" />
+    <!-- require ReplyCommand<Boolean> to deal with view focus change event.
+    ReplyCommand would has params which means if view hasFocus.-->
+    <attr name="onFocusChangeCommand" format="reference" />
+    <!-- require ReplyCommand<MotionEvent> -->
+    <attr name="onTouchCommand" />
+    ```
+
+  - *ListView*、*RecyclerView*
+
+    ```xml
+    <!-- require ReplyCommand<Integer> -->
+    <attr name="onScrollStateChangedCommand" />
+    <!-- require ReplyCommand<ListViewScrollDataWrapper> -->
+    <attr name="onScrollChangeCommand" />
+    <!-- require ReplyCommand<Integer> count of list items-->
+    <attr name="onLoadMoreCommand" format="reference" />
+    ```
+  - *ViewPager*
+
